Abstract:

This paper presents analysis of a Newell-type stochastic car-following model based on stochastic desired acceleration processes. This formulation was shown to generalize previous efforts based on Brownian and geometric Brownian acceleration processes, each reproducing a different feature of the traffic instabilities. Here, we show that the unified model is able to capture virtually all types of traffic instabilities consistently with empirical data, including formation and propagation of oscillations, capacity drop in the absence of lane changes and the concave growth pattern of vehicle speeds along a platoon.
