Regional issues on road accidents and trafc injury in Ukraine

This paper aims to analyse death and injury frequencies caused by road accidents in different regions of Ukraine. Types of road accidents and their degree of severity are analyzed, in addition to the level of road accidents in Ukraine compared to the same parameters in Europe. 2007 and 2013 death rates and injury rates due to car crashes or trafc accidents are considered as ratio per 1,000 inhabitants and 1,000 cars. An overall geographically featured assessment of road injuries has also been computed for each administrative region of the country. An evaluation of an integrated road safety index based on the statistical analysis of road accidents indicators has been developed (primarily making use of factor analysis such as principal component analysis and correlation analysis). Assessment of an integrated road safety index has been introduced since this enabled us to differentiate and identify a variety of regional categories related to traumatism and mortality rates due to road accidents.


Introduction
Ukrainian demography has experienced and continues to face serious mortality dynamics, most aspects being problematic.According to some specialists Ukrainian population goes through a mortality crisis determined by a long-term negative trend during 1965-1984.This trend grew and intensied by the consequences of the Chernobyl disaster in 1986 and the negative impact of the protracted economic crisis during 1991-1998.Unfortunately, the mortality rate in Ukraine over the past ten years remains one of the worst ones as compared to mid-1990s, when the maximum of the population mortality occurred.The extended stagnation of high mortality rate caused the depopulation in Ukraine.During the past ten years (2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015), the overall mortality rate in Ukraine has been kept at a quite high a level compared to the European countries 14.7-16.6‰(Kovalchuk, 2014;Kvitashvili, 2015).
The current structure of causes of death of the population of Ukraine combines elements of traditional and modern structures of pathologies, in which the high mortality rate from endogenous diseases (cardiovascular diseases and neoplasms) is coupled with equally signicant mortality from diseases of respiratory apparatus, digestive system, infectious, parasitic diseases and external (exogenous) reasons, rst of all, as injuries (Kvitashvili, 2015).Road trafc accidents have a special place among the external factors causing injuries and increasing morbidity and mortality.Since the 2010s, about 4,500-5,000 people die each year due to road accidents in Ukraine, which is about 1% of all deaths in the country and about 15% of all deaths caused by external factors (Kvitashvili, 2015;Statistical yearbook, 2015).Each year another 45,000-50,000 people are injured because of car crashes/road accidents (Statistics of road accidents, 2016) ( ). Figure 1 Accidents on the roads and their consequences are the subject of attention for physicians, economists, sociologists, road construction experts, logistics, etc. (Lyebyedyeva, 2015;Myronenko, 2013).Not so many scientic papers are dedicated to geographical aspects of road trafc accidents in Ukraine.They deal with the quantitative characteristics of the accidents at the Ukrainian roads and their dependence on the level of socio-economic development of regions  (Avramenko, 2015).In another study (Statystyka, 2014) is compared mortality rate in road accidents in Ukraine and other countries of the world.Geographical analysis of trafc accidents in some regions of Ukraine, including geography and dynamics of accidents, is presented by Shischuk et al. (2016).
The main goals of the present article are: to reveal the major indicators of trafc crashes-leading to increased danger on roads and to characterise the main types of road accidents and their inuence on mortality and traumatism rates.We also aim to estimate the level of road safety for all regions of Ukraine by determining the road safety index (RSI).

Methodology
A complex methodology was applied to determine the level of road accidents in different regions of Ukraine.It consists of several stages, such as: 1) selection of indicators reecting the number and severity of accidents on the Ukrainian roads and streets and the number of culprits/accident, as well as causes for the occurrence of trafc crashes; 2) bringing diverse indicators to a single standardised range by the feature scaling; 3) calculation of the integrated road safety index.
Many data sources allow you to compare road safety in the EU, Ukraine and other countries around the world.Back in 2004, the World Health Organization (WHO) and the World Bank published the World report on road trafc injury prevention (Peden, 2014).It contained extensive information on the key risk factors for road trafc injuries, information about effective measures and recommendations on how countries can improve a road safety.In 2009, the rst data on the implementation of these recommendations were published in the Global status report on road safety: time for action.
In 2010, the UN General Assembly unanimously adopted the resolution 64/255 (Improving, 2010), and called for to undertake in the 2011-2020 the Decade of Action for Road Safety.To track the results of the Decade on national and global levels, it was proposed to prepare follow-up reports on road safety.The Decade of Action for Road Safety (2011-2020) (Global plan, 2011) calls on countries to implement the measures identied internationally to make their roads safer.The UN General Assembly invited WHO to monitor progress through its Global status report on road safety series.At the end of 2013, the Global status report on road safety 2013: supporting a decade of action was published.
During 2013-2015 worldwide the total number of road trafc deaths has plateaued at 1.25 million per year, with the highest road trafc fatality rates in low-income countries.But, while there has been progress towards improving road safety legislation and in making vehicles safer, the report shows that the paces of change are too slow.Urgent action is needed to achieve the ambitious target for road safety reected in the newly adopted 2030 Agenda for Sustainable Development: halving the global number of deaths and injuries from road trafc accidents by 2020.
The next Global status report on road safety 2015 contained information obtained from 180 countries (Global status, 2015).Three types of trafc accident mortality data are presented in the report: (i) the data reported by the national focal points; (ii) the corrected data; (iii) the comparable estimates.Data reported by national experts are presented in the report in the appropriate 'country proles'.It also identies data sources, the period to which they relate, as well as the time frame used in the accounting of deaths from road accidents.To minimise the impact of differences in the denition of death from accidents and harmonise data from different sources, they were corrected by 30-day denition for their ofcial road trafc fatality data.The comparable estimates (and their corresponding 95% condence intervals) were developed to compensate data underreporting in some countries and to assess mortality from accidents in all WHO member countries of 2013.Unfortunately, Ukraine was not included in this global WHO report.
Besides that, The United Nations Economic Commission for Europe (ECE) publishes the Bulletin on statistics of road trafc accidents in Europe and North America.In 2015 the fty-third edition of the Statistics of Road Trafc Accidents in Europe and North America (Statistics, 2015) was published; it contains basic statistics on road trafc accidents provided by the Governments of 56 member countries of the United Nations Economic Commission for Europe (UNECE).The statistics in this document is limited to road trafc accidents involving personal injury, and excluding accidents where only damage to vehicles is reported.
The Statistics for Road Trafc Accidents in Europe and North America is divided into three basic parts.The rst part sets out charts and summary tables on the overall situation and developments in road trafc accidents and casualties in UNECE countries.The second part provides detailed statistics on road trafc accidents and includes the details of accidents such as location, time of occurrence, road condition, personal injuries and deaths.The third part shows background statistics on countries' vehicle eets and estimates of the vehiclekilometres run.
In Ukraine, the statistics of accidents, deaths and injuries in the road accident is provided by the Ukrainian medical council for road trafc of Ministry of Health and the Ofce for Road Safety of the National Police of Ukraine.The Ministry keeps statistics of trafc accidents by WHO methodology (International, 2015), so its representation is much better and more objectively reects the situation on the roads of Ukraine.However, these data are not published nowhere.Thus, the data from the Ofce of Road Safety are only available.
To study the features and trends of road accidents on the roads of Ukraine we used various indicators characterizing its two main aspects of this problem: a) the number and severity level of accidents (the total number of deaths and injuries resulting of road and street trafc crashes; the total number of all accidents per number of accidents with victims; percentage of accidents with victims of the total number of trafc accidents; the number of fatal and non-fatal accidents with victims that have occurred within settlements, and the percentage of these accidents of all trafc accidents with victims.Based on the analysis of these indicators, the death and injuries rate per 1,000 cars/people was calculated for each administrative region separately, and b) the structure of the road trafc Regional issues on road accidents 201 accidents (in particular, the structure by types of crashes (collisions with another vehicle, include head-on and rear-end collision, angle or side impacts; rollover crashes, collision with stationary vehicles; collision with stationary obstruction, such as a tree, utility pole or road debris; collisions involving pedestrians and cyclists; collisions with animals and cartage transport; passengers fall (from a moving vehicle or inside it due to hard braking, accelerating or changes in direction of movement) and cargo carried fall or fall of subject, rejected by wheel on human, animal or another vehicle was investigated); the number and percentage of accidents that have occurred due to drivers (including drunk drivers) or due to pedestrians (including children) were calculated separately.
All necessary data for calculations we have received from the Ofce of Road Safety of the Department of preventive activity of the National Police of Ukraine (Statistics of road accidents, 2016).
Normalized data were calculated for each region.The equation for normalizing is the following: (1), where X' -the data point i normalized between 0 and 1; x -each data point; x i min -the minimum value; x -the maximum value.
max Scaling (unity-based normalisation) was used for bringing all values into the range [0, 1].Therefore, all parameters should have the same scale for the appropriate comparison.The value 0 and 1 are characteristic of regions with, respectively, the smallest or the largest value of a given indicator among the administrative regions of Ukraine.
As has been stated above, the rst step in the calculating of RCI was a selection of indicators of road trafc accidents and the severity of accidents.Such indicators were: a total number of road accidents; trafc accidents in settlements; road trafc deaths; road trafc injuries; rollover crashes; collisions with stationary vehicles; collisions with stationary obstruction; collisions involving pedestrians; collisions involving cyclists; another types of road crashes; road accidents due to drivers; persons killed due to drivers; persons injured due to drivers; road accidents due to drunk drivers; persons killed due to drunk drivers; persons injured due to drunk drivers; road accidents due to pedestrians; persons killed due to pedestrians; persons injured due to pedestrians; road accidents due to children-pedestrians; persons killed due to childrenpedestrians; persons injured due to children-pedestrians in 2007 and in 2013.
The second step was bringing of diverse indicators characterising the frequency of different types of road crashes, traumatism and mortality in trafc accidents to a single standardised range by feature scaling by the procedure mentioned above.The sum of the standardised values of these indicators characterising the frequency, traumatism, and mortality in trafc accidents is an integrated RSI.This index is the coefcient, which characterises the level of the road safety in the separate administrative region.
All calculations and statistical computations (factor analysis, in particular, principal component analysis and correlation analysis) and test the statistics, as well as the graphical representations were obtained by using the capabilities of

Main determinants affecting road safety
The high level of road trafc accidents in Ukraine is highly dependent by three groups of factors, known as 'epidemiologic triad' (Haddon, 1972): human factors, vehicles and equipment factors, and environmental factors.
Human-related factor.First of all the high level of road trafc accidents in Ukraine is highly dependent by the human factor: behaviour of drivers, their unpreparedness, foolhardiness on the road, drunk driving, drunk pedestrians, and, nally, violation of road rules by drivers and pedestrians.The main responsibility for the accident and its consequences lies with the drivers.According to statistics for 2013, about 25,600 of the nearly 30,700 road accidents with victims (83.6%) were due to drivers fault.If we take these estimates, it is clear that the main attention should be paid to the behaviour of the person behind the wheel.Speeding is the main contributing factor in fatal crashes.Both excess speed (exceeding the posted speed limit) and inappropriate speed (faster than the prevailing conditions allow) are important causation factor of road accidents.These are the most frequent violations by Ukrainian drivers involved in an accident.As in European countries (Road Safety, 2014), speeding in Ukraine is the cause of about 30% of fatal accidents, e.g. the share of fatal crashes in Ukraine due to excessive speed was 31.3% in 2013 (Statistics of road accidents, 2016).
However, speeding is only one of the trafc violations, although it is the most fatal.About 20.2% of all road trafc accidents with victims in Ukraine were attributed to a violation of the rules of manoeuvring, and 7.2% -crossing of intersections as the main causes for the crash (Statistics of road accidents, 2016).Drunk driving is the third major cause of car crashes and casualties in Ukraine.In 2013, 6.6% of fatalities were due to drunk driving.Drunk drivers ignore the trafc rules very often and usually fall on their feet in any case.
Another problem of road safety in Ukraine is the attitude to passive safety.The proportion of seat-belt use is 27% for drivers and 25% for front seat passengers (in passenger cars).At the same time, about 10% of Ukrainian drivers believe the seat belts are useless, so these people fasten their seatbelts in extreme cases only.Moreover, almost 10% of drivers believe that use of seat belts is pointless or even dangerous.
Vehicle-related factor.In 2013, the road vehicle eet of Ukraine totalled 6.9 million of passenger cars, about 1.3 million lorries and road tractors, as well as 253 thousands of buses (Statistics, 2015).Vehicle eet of Ukraine is quite old.Almost 27% of it is older than 25 years.Let us add to it 2.8 million vehicle age from 10 to 15 years.It turns out that 6 of 10 vehicles are over 10 years.The average age of passenger car eet is 19.6 years (average age in EU-28 countries is 9.7 years) (The automobile, 2015).
Motorization rate for a long time considered as one of the most important factors, determining the number of road accidents and the severity of their effects.Over the past decades, the level of motorisation of the population of the EU-28 has increased signicantly -from 334 cars per 1,000 resident population in 1991 to 473 in 2009 and 564 in 2013.The value of motorisation rate among the countries of EU-28 varied in 1991 from 63 per 1,000 people in Romania to 522 in Luxembourg, and in 2013 -from 253 to 769 cars per 1,000 people in these countries (Motorisation rate, 2015; The automobile, 2015).During 2005-2007, the growing level of motorization rate in Ukraine (from 111 to 121 cars per 1,000 Inhabitants) was accompanied by an increase of a road accident mortality rate (from 1.37 to 1.7 deaths per 1,000 cars) as well as injury rate (from 10.57 to 13.94 victims per 1,000 cars).However, in subsequent years, the motorisation rate in Ukraine was continued to grow, and reaching 204 cars per 1,000 inhabitants in 2013, while the injury rate and death rate declined and stabilised at the level of 5.8 and 0.8 victims per 1,000 cars, respectively.
Despite the big number of old cars, the percentage of trafc accidents where the emergency state of the vehicle was the main reason is usually small.In Ukraine, the total number of persons killed in road accidents due to vehicle malfunctions in 2013 was of only 61 (1.2%).The main causes of such accidents in Ukraine are the failure of the brake system and excessive tire wear (Statistics of road accidents, 2016).In addition to the drivers, pedestrians acting as violators of trafc rules contribute to the deterioration of the situation on roads.Pedestrian culture in Ukraine is rather poor.People often cross the streets, ignoring pedestrian crosses and red lights.According to the Trafc Police, for 2013 because of violations of trafc rules by pedestrians 4.4 thousands of accidents were registered (14.4% of all trafc accidents with victims), which killed 1,000 and injured about 4,000 people.The most common type of violation is the transition of the carriageway at an undisclosed location or an unexpected exit of pedestrians to the roadway.These two kinds of violations accounted 81.2% of the total number of road accidents committed by pedestrians (Statistics of road accidents, 2016).
Environment-related factor.The total length of public paved road in Ukraine is 166.1 thousand km (Statistical yearbook, 2015).The road network in Ukraine is 2 characterised by low density -0.28 km road/km land area.At the same time, in neighbouring Slovakia, the road density is 0.88, and in Romania -0.47 km 2 road/km (Road Statistics Yearbook, 2016).A small length and the density of the road network cause a big number of vehicles per km of road in comparison with other European countries.Today in Ukraine are over 50 vehicles per km of road, while in Slovakia -47.6, and in Romania -45.5 vehicles per km of road.Usually, every day the Ukrainian Trafc Police registered about 500 violations of road rules.But it has a strong reputation for shing for bribes, so the control of road safety in Ukraine is very weak, resulting in a weak driving culture.
The acceleration of motorisation has not yet led to a corresponding increase in the volume of construction and reconstruction of the road network.From 2001 to 2013, the Ukrainian car eet increased by 2 times, but the length of paved roads increased by only 1.3% (Transport and Communications of Ukraine, 2014).One of the main problems of the Ukrainian road network is its low quality.Only about 40% of Ukrainian paved roads comply with the regulatory requirements for transport and operational indicators of strength, 37% have an unsatisfactory evenness of pavement.Overall, about 60% of the public paved roads do not meet the regulatory requirements.On the motorways, there are many single-level three-way intersections, and four-way crossroads, inadequate security of barrier fences, bad lighting and road markings, about 20% of bridges are in poor condition (Transport and Communications, 2014).There are no sidewalks; roadsides are in bad condition due to the dangerous location of trees and poles.
Ambulance in Ukraine provides almost complete coverage of accidents in urban areas, but it is fewer when it comes to long-distance roads, where about 30-35% of all road accidents occur.In urban areas, emergency medical services provide help quickly enough, but on the roads, it takes time for the arrival of the medical team.There is a 30-minute standard, which the ambulance tries to maintain, although this is not always possible.In Ukraine the system of organisation of emergency team arrival to the scene of an accident and assistance to the victims is ineffective.Almost 70% of the cases of deaths which occur are directly linked with the transportation of victims to hospitals.Often the victims are transported from the accident site by a passer-by.When transported by passers-by killed more than 80% of the victims.Only 20% of deaths before arrival at the hospital were associated with injuries incompatible with life, and 80% due to inadequate medical care at the accident scene and during transport to the hospital (Shyschuk, 2011).
Hospitals provided their specialised care differently, and not all of them have a staff of traumatologists and equipment for treatment of victims with multiple and severe injuries.Treatment of patients can be performed by surgeons without sufcient and modern training in the eld of traumatology.Also, not all hospitals that receive the victims of road accidents are staffed by a trauma surgeon.This leads to next transporting of victims, which increases the time to provide a qualied medical care.It is interesting that 70% of drivers do not know the purpose of medical preparations, which are in the rst-aid kit.The shelf life of medicines, stored therein, is not controlled (Shyschuk, 2011).

Road accidents in Ukraine and Europe -a geographical approach
Each year in Europe, road trafc accidents killed over 90 000 people, and about 26 000 people died on the roads of the European Union (Road fatalities, 2016).Road trafc injuries in the WHO European Region result in an annual loss of 3.6 million years of healthy life due to premature death or disability (disabilityadjusted life-years).The loss of national productivity is an economic threat, resulting in high social costs equivalent 0.36-3.90% of the gross domestic product (Beckmann, 2007;Borovkov, 2011).Annual losses of Ukraine due to accidents are USD 4-5 billion (Koskovetskyi, 2015).
A large number of the non-fatal injuries (taking into account the cost of medical care, social security payments, production losses, etc.) for the country is more expensive than fatal accidents.For the WHO European Region, this translates into hundreds of billions of euros, including health service costs to treat and rehabilitate injured peoples (Global status, 2015;Jackisch, 2015).
For every death on European roads, there are any four permanently disabling injuries such as damage to the brain or spinal cord, eight serious injuries and fty minor injuries.In 2013 death rate in road trafc accidents in the European Union was 5.9 per 100,000 inhabitants, that is below the world average, which is 18.8 per 100,000 inhabitants (Causes of death, 2013; Road trafc deaths, 2016).
However, there are signicant differences in mortality in road accidents in different European countries.In low-and middle-income countries, this gure shows a twice as high index of high-income countries.For example, Sweden, Denmark, the United Kingdom are characterized by one of the world's lowest mortality rates in road accidents (about 3-4 deaths per 100,000 inhabitants).Among the EU countries, the highest rates of road trafc deaths in 2013 are in Lithuania and Poland -10.6 and 10.3 per 100,000 inhabitants, respectively (Road trafc deaths, 2016).
Compared with this, the average death rate in road accidents in the CIS countries is almost four times higher.The highest rate among them is in Kazakhstan (24.2 deaths per 100,000 inhabitants), next followed by Kyrgyzstan (22.0 per 100,000 people) and the Russian Federation (18.9 per 100,000 inhabitants).Many Western European countries tended to decrease the number of car crashes and mortality in trafc accidents (Road trafc deaths, 2016).At the same time, in the eastern part of Europe, the reverse trend is observeddeath rates in the road accidents remain constant or growing there.For example, in Ukraine, the death toll on the roads and streets during 2010-2014 amounted to 4,400-5,100 people annually.The rate of road accidents for the year 2013 was 0.68 accidents with victims per 1,000 inhabitants.In 2013, about 170 people perished per 1000 road accidents with victims.The injury rate in the accidents on the roads in 2014 was 1,241 per 1,000 registered trafc accidents with victims in Ukraine (Statistics of road accidents, 2016).
Pedestrians are the main category of people who killed in road accidents.In 2013, 1,888 pedestrians (39.1% of all road trafc deaths) were killed in the trafc accidents (Statistical yearbook, 2015).Approximately the same portion is drivers and passengers of cars, who killed in trafc accidents -1,874 people (38.8%).About 70% of all perished drivers and car occupants have not used the seat belts (Statistics of road accidents, 2016).As can be seen, these two categories account for about 80% of all deaths on the Ukrainian roads.In 2007, the percentages of the types mentioned above of road users were lower: pedestrians -37.5%, drivers and car occupants -29.9% (Statistical yearbook, 2015).
That is why we focus on the geographical features of road injuries, including the fatal accidents, in different regions of Ukraine.Also, we drew attention to the two main groups of culprits of such accidents: drivers and pedestrians, who are both the main victims of the road accidents.
The highest rate of accidents with victims in 2007 was observed in the city of Sevastopol' and the Kyiv region (more than 2 trafc accidents per 1,000 inhabitants.High, relative to the average in Ukraine, was the level of road accidents in Donets'k, Odesa, Chernivtsi, Zaporizhzhya, and Dnipropetrovs'k regions (1.5-2 accidents per 1 000 inhabitants).The smallest amount of the road accidents per 1,000 people was registered in the Ivano-Frankivs'k (0.86), Ternopil' (0.77) and Chernihiv regions (0.64 accidents per 1,000 inhabitants).In 2013, the most of all road trafc injuries remain in Sevastopol' and Odessa region (1-1.25 accidents per 1,000 people); slightly best situation was recorded in the Chernihiv, Ivano-Frankivs'k and Ternopil' regions -0.28-0.30accidents 206 Anatolii Kornus et al. with victims per 1,000 inhabitants (Figure 2).
However, the number of accidents is not always consistent with their severity.In particular, most of all fatal accidents during 2007 were observed in Kyiv (0.45 road deaths per 1,000 inhabitants), Zhytomyr (0.27), Chernivtsi (0.27), Poltava regions and in the Autonomous Republic of Crimea (at 0.26 killed in road accidents per 1,000 population).In 2013, fatal accidents were also more often in Kyiv, Chernivtsi and Zhytomyr regions, although the death rate due to the transport accidents has been decreased to 0.15-0.23 per 1,000 inhabitants.
Given the different level of motorisation in the regions of Ukraine, the highest rate of the road accidents in 2007 was observed in the city of Sevastopol' (18 road accidents with victims per 1,000 cars), as well as Odessa and Donets'k regions (17.0-17.6 road accidents per 1 000 cars).Best situation was in the city of Kyiv (6.8), and in the Chernihiv and Transcarpathian regions (7.7-7.8 road accidents with victims per 1,000 cars).The majority of the fatal accidents happened in Chernivtsi and Kyiv regions -2.7-2.8 road deaths for 1,000 cars and the best situation was in Kyiv (0.75 fatalities per 1,000 vehicles).
In 2013, despite the increase of motorisation in all regions of Ukraine, the level of the road trafc injuries had signicantly declined.This again suggests that the motorisation rate today is not the index determining the level of road trafc injuries.The number of road accidents in the city of Sevastopol' decreased from 18.0 to 10.3 and, for example, in the Donets'k region -from 17.6 to 7.4 road accidents with victims per 1,000 cars.The best situation was in the Ternopil', Vinnytsia, Mykolayiv and Kirovohrad regions, where 2.4-2.5 road accidents with victims per 1,000 cars were recorded in 2013 (Figure 3).As in previous cases, the number of accidents is not consistent with their severity.In particular, most of all fatal accidents during 2013 were observed in Chernivtsi (1.16), Poltava and Zhytomyr, regions (1.27 road fatalities per 1,000 cars).Such a discrepancy between the number of road accidents and the number of deaths may indicate deciencies of health care for persons affected by road accidents in different regions of Ukraine.

Road safety index by Ukrainian regions
For the overall assessment of the geographical features of road injuries, we have been computed the value of RSI for 2007 and 2013, calculated by the method described above for each of the administrative regions of Ukraine.In amount 2007, the largest number of best indicators (12 of 23) of the low level of the road accidents and trafc injuries are in two regions -the cities of Kyiv and Sevastopol'.Kyiv is characterised by the smallest standardised values of the road accidents with victims of the total number of all accidents, as well as crashes with rollovers, collisions involving pedestrians and cyclists in the structure of accident with victims.Also in Kyiv, there are the smallest amount of accidents due to drunk drivers and the lowest standardised values of accidents that have occurred due to of children-pedestrians, as well as the number of children, injured in such accidents.
Sevastopol' is characterised by the smallest standardised value of mortality rate in the road accidents (only 0.08 perished per one accident), the least amount of collision with stationary obstruction in a road accidents structure.It may indicate a better quality of the street surface and good trafc organisation.In this city are the lowest amount of accidents occurred due to drivers -44.96% (an average of Ukraine is 78.85%) and the standardised values of killed and injured people in the accidents for this reason (Figure 4).
If we talk about the outsiders of our regional ranking, after Khmel'nyts'ky region, Chernivtsi, Chernihiv, Kherson, Transcarpathian and Volyn' regions included into a group with the bad situation on the roads: the RSI value in 2007 not reached 10.0 (the average of Ukraine was 12.5).Analyzing the same data for 2013, it can be seen that in most regions of Ukraine the level of the road safety has been improved.This was facilitated by changes in trafc rules, in particular the tightening of legislation, adapting to the requirements of the European Union ( 2008), increased penalties for violation of the rules: driving a car while drunk -from 32-52 to 350 , speeding -from 1.3-2.6 to 70 , non-use of seat belts -from 1.1 to 8.5 (Road safety, 2012) as well as the repair or reconstruction of more than 2,000 km of main roads, made in preparation for the UEFA Euro 2012.However, the safety situation on the roads in some regions did not improve, yet deteriorated.
In 2013, the low value of RSI was recorded only in the Kherson region (Figure 5), mainly due to the undisciplined drivers.In this region there is the highest share of accidents with victims due to of drivers, the largest proportion of killed and injured in such accidents, etc.
As in 2007, Kyiv characterised by the safest roads: there was the lowest standardised value of road accidents with victims of the total number of all road accidents; the smallest proportion of rollover crashes among the trafc accidents with victims; the smallest amount of killed and injured people in road accidents due to child-pedestrians.Also in Kyiv are the smallest severity of accidents -only 0.07 persons killed per one accident with victims (0.15 in average for Ukraine), the lowest standardised value of accidents with victims occurred due to drivers, and the lower value of deaths and injuries in accidents of the same type.
The other leaders of this regional ranking in 2013 are the Transcarpathian region and Sevastopol'.In the Transcarpathian region is characterised by the smallest amount of car collisions among the accidents with victims, the lowest proportion of accidents with victims due to drunk drivers, the smallest standardised value of perished and injured people in accidents caused by drunk drivers.In addition, the smallest amount of accidents with victims occurred due to of pedestrians, including the fault of the children, was also recorded for the Transcarpathian region.
Bottom of our rankings, besides the Kherson region, consists of Khmel'nyts'kyi, Chernihiv, Volyn' and Vinnytsia regions where the RSI value in 2013 did not reach 11.5, while the average in Ukraine was 12.9.Moreover, the road safety in the Vinnytsia region during 2007-2013 is the most deteriorated as compared with other regions.

Conclusions
The analysis of the frequency of injuries and mortality in road accidents at the regional level in Ukraine allow us to dene certain spatial features of the  210 Anatolii Kornus et al. distribution of these indicators and on the non-random nature of the location of their values that is shown on maps of Ukraine.Based on the methods of statistic analyses, we have demonstrated the existence of a spatial structure in the distribution of the risks and consequences of trafc accidents in different regions of Ukraine.
In 2013, the road trafc death rate in Ukraine was about 10.7 per 100,000 population.This level was lower than in the Russian Federation (18.2),Belarus (13.7), and Republic of Moldova (12.5).However, the mortality rate in road accidents in Ukraine was much highest than in neighboring EU countries (Road trafc deaths, 2016): Bulgaria (8.3), Hungary (7.7), Romania (8.7), Slovakia (6.6 deaths per 100,000 population), and much worse than, for example, in Germany (4.3).As it can be seen, the death rate in road accidents in Ukraine is almost the same as in Lithuania (10.6) or Poland (10.3).
The value of RSI in 2007 is ranging from 8.5 in the Khmel'nyts'kyi region to 14,4-14,7 in Kyiv and Sevastopol' In 2013, the value of road safety index was ranged from 9.9 in the Kherson region to 16.7 in Kyiv.RSI enabled us to distinguish regions categorised by traumatism and mortality rates of road accidents.Based on analysis of these indicators we have introduced the evaluation of an integrated safety level for the different regions of Ukraine.This allows us to estimate the complex inuence of the risks and their consequences (trafc accidents) on the level of safety for certain regions or their groups.
Most of the trafc accidents were due to driver factors.The percentage of accidents with victims occurred due to the fault of drivers in 2013 ranged from 57.28% in Kyiv to 91.19% in Kharkiv region.The main causes of accidents are speeding, unsuccessful manoeuvring, unsafe lane changes, violation of rules in the crossroads or marked crosswalks, driving a vehicle while intoxication through drink or drugs.Because of these violations in Ukraine committed about 55% of accidents.The statistics show that drivers, who commit trafc accidents, incorrectly assess their skills and ability to drive, can't anticipate dangerous situations and, consequently, can't properly deal with such cases.Many die as a consequence of inexperience or just plain recklessness.
The results of our research can be used for the improvement of national and regional programs of road and transport safety, as well as for the development of strategies and actions aimed at reducing the risks and consequences of trafc accidents in the regions of Ukraine.It is necessary to establish in more detail the reasons underlying the emergence of these factors at the local, regional or national levels and, by taking these reasons into account, to develop a complex of target actions to its reducing.
