Anticipatory drivers in the Nagel-Schreckenberg-model

摘要

The Nagel-Schreckenberg-model (NaSch-model) describes macroscopic features of real traffic very well. However, the characterization of a single car driver's behavior in some details is not realistic, e.g., the NaSch-driver calculates his/her distance to the car in front from the position this car has just in the very moment and ignores that it could move further in the next time step. This behavior is rarely found in real traffic. Normally, a driver estimates the speed of the car in front, takes as well a certain braking distance into consideration and keeps distance accordingly. As an answer to this demand, the second rule of the NaSch-model is modified in the following. [References: 2]
