Feasibility of Modeling Lane-Change Performance

This paper examines the feasibility of using four driving states (low risk, conflict, near crash, and crash imminent) to characterize lane-change driving performance. Data are analyzed from a test track study to estimate the boundaries between the states and to show that performance maps can be created for lane-change events in two simple scenarios. The map structure is further investigated using naturalistic on-road data and the agreement between the test track and on-road data models is discussed. Implications for crash counter-measure development and evaluation are discussed.
