One limitation of point-based detectors is their inability to estimate directional demand （i.e. number of leftturners, through, and right-turners） at intersections. This affects traffic signal systems that have separate rightturn phases. Right-turners often experience significantly longer waiting times due to short green-time allocations despite low demand in other directions from the same approach. We developed a method for estimating rightturn demand and travel times by combining high-resolution detector data and probe data from infrared beacons （UPLINK data）. The method was tested on real-world traffic data and the potential effect of improving greentime allocation is shown.
