Improved Car-Following Model Considering Modified Backward Optimal Velocity and Velocity Difference with Backward-Looking Effect

Full velocity difference model for a car-following theory.

In this paper, we present a full velocity difference model for a car-following theory based on the previous models in the literature. To our knowledge, the model is an improvement over the previous ones theoretically, because it considers more aspects in car-following process than others. This point is verified by numerical simulation. Then we investigate the property of the model using both an...

A Modified Optimal Velocity Model for Vehicle Following

This paper presents a modified optimal velocity model (MOVM) for vehicle following. It makes use of time to collision (TTC) in order to reduce the reference speed when relative speed against the leading vehicle is negative. Simulation results have shown an anticipation behavior which leads to smoother maneuvers. The driver risk perception of rear-end collision is also enhanced. Copyright c ©200...

Looking Forward to Looking Backward

Decisions are powerfully affected by anticipated regret, and people anticipate feeling more regret when they lose by a narrow margin than when they lose by a wide margin. But research suggests that people are remarkably good at avoiding self-blame, and hence they may be better at avoiding regret than they realize. Four studies measured people’s anticipations and experiences of regret and self-b...

Deregulation: Looking Backward and Looking Forward

An improved car-following model considering variable safety headway distance

( a Department of Civil Engineering, Tsinghua University, Beijing 100084, China) Abstract: Considering high speed following on expressway or highway, an improved car-following model is developed in this paper by introducing variable safety headway distance. Stability analysis of the new model is carried out using the control theory method. Finally, numerical simulations are implemented and the ...
