急刹车对车联网交通流的影响
Influence of Sudden Braking on Traffic Flows of Internet of Vehicles
摘要
Abstract
In view of the different ranges of obtaining traffic information ahead based on visual percep-tion and vehicle-to-vehicle communication,the limitations of vehicle deceleration ability,and the changes in driver psychology,the deterministic deceleration rules and stochastic deceleration rules were optimized on the basis of the traditional brake light model.An improved cellular automaton traffic flow model considering the influence of sudden braking was established in the internet of vehicles envi-ronment to quantitatively analyze traffic flow phenomena in the area affected by sudden braking.The simulation results show that the vehicle can perceive the position of the vehicle during sudden braking in advance and smoothly decelerate according to the recommended maximum speed in the area.The number of vehicle accidents can be decreased by 82%.关键词
