Abstract
An increase in traffic crashes can be attributed to inconsistencies in roadway geometry. The operating speed model is a statistical tool to evaluate geometric design consistency. This paper explores the relationship between radius, gradient, sight distance parameters, extra widening, and operating speeds at two-lane two-way non-urban roads in India. Data of 107 curves and 107 tangents with horizontal within crest curve combinations were selected. Correlation analysis was done to find the significant geometric variable affecting the operating speed of vehicles. Using these significant variables, operating speed models were developed using a mixed effect modeling approach for different classes of vehicles.
