Research on car-following model based on SUMO

摘要

Vehicular Ad Hoc Network (VANET) is a promising platform for the Intelligent Transportation System (ITS). Car-following theory is a significant research direction in the field of VANET, it describes the one-by-one following process of vehicles on the same lane in traffic flow. The paper analyzed Krauss car-following model and proposed a new model based on the speed safe and Krauss model in SUMO 0.21.0 platform to improve the authenticity of model. We implement it on the SUMO platform. This model considers the movement state of the car and the gradual process of deceleration in vehicles braking. Simulation experimental results show the superiority of new model over other ones in simulation that models real streets. It achieves good results in wait time, travel time, lane-change number and safe speed.
