Identifying Vehicle Trajectories and Turning Movements at Roundabouts
Studying the performance of roundabouts is a challenging task. The events that take place occur far apart from one another: at the entrances and exits and even the road segments in-between. Consequently, roundabouts are quite different from other types of junctions, such as signalized intersections, where all the events effectively take place at a single point. For roundabouts, just identifying the turning movements is a challenging task. Moreover, when the flow rates are high, it is easy to lose track of vehicles. This paper describes a way in which timestamps can be used to identify vehicle trajectories and estimate turning movement volumes. The method for chaining the timestamps together is discussed as well as effective and efficient ways to collect the data in the field. Several examples are presented. The relationship of these ideas to other estimation techniques is discussed.
