当前交通仿真中,隐含假设车辆由理想司机驾驶.仿真车辆总做出合理决定,如绿灯变亮时车辆就立即驶离.这导致仿真与实际交通存在差距.研究表明,即使是遵守交规的司机,也在绿灯时延迟驶离汽车.司机若在等待时被手机等事物分散注意力,车辆延迟启动(SUD)更为严重.SUD很少体现在交通模拟中.需要对SUD进行模拟,研究其对路网交通流的影响.并研究不同车辆密度和网络复杂度对结果的影响.通过参考SUD对道路通行能力的影响,工程师可以更好地设计路网.“,”In current traffic simulations,it is implicitly assumed vehicles are driven by ideal drivers.Therefore,simulated vehicles make the most reasonable decisions such as moving out immediately when traffic lights turn green,resulting in a gap between simulations and real traffics.Research shows that drivers,including those who follow the rules,show a delay in starting-up their vehicles at the green light.The vehicle startup delay (SUD) is even more significant for drivers by things such as cell phones during waiting.However,the SUD has rarely been considered in simulations.The SUD is simulated to study its impacts on the traffic flow of road networks.Multiple scenarios with various vehicle densities and network complexities are simulated to investigate the influences of these factors.The analytical results can also help transportation engineers to better design road networks by providing references as for road capacities when affected by SUD.
