主 题:traffic flow cellular automaton backward-looking perception range hysteresis phenomenon
摘 要:With Connected Vehicle Technologies being popular,drivers not only perceive downstream traffic information but also get upstream information by routinely checking backward traffic conditions,and the backward-looking frequency or probability is usually affected by prevailing traffic ***,the bi-directional perception range of drivers is expected to significantly increase,which results in more informed and coordinated driving ***,we propose a traffic flow bi-directional CA model with two perception ranges,and perform the numerical simulations with the field data collected from a one-lane highway in Richmond,California,USA as the benchmark *** results show that the CA model can effectively reproduce the oscillation of relatively congested traffic and the traffic hysteresis *** adjusting the backward-looking probability and the perception range,the CA model can well simulate the travel times of all vehicles,and the generation and dissolution of traffic jams under various scenarios.
