Driver Approach and Traversal Trajectories for Signalized Intersections Using Naturalistic Data
The objective of this paper is to model driver intersection approach and traversal trajectories in response to traffic signals and driver behavior based on stopping behavior. This study analyzed 12,688 observations from signalized intersections from the CICAS-V project (1) database. The selected data were subjected to Multivariate Adaptive Regression Splining to develop a model of a typical driver’s velocity on their approach to the intersection based on the vehicle’s proximity to the stop bar (range [m]) and other categorical factors such as vehicle type, time of day, road surface condition, and weather. The resulting models highlight how driver approach speeds vary as a function of range and other factors depending on the signal phase and intended course of action. The models predict the vehicle speed as a function of distance to the stop bar of the intersection (range). The results suggest that the behaviors of red and yellow light runners are difficult to distinguish from each other, but it is possible. These models will be used to calculate vehicle approach speeds in real-world intersection crashes.
