合作合流对交通流同步流相位的影响
Effect of cooperative merging on the synchronous flow phase of traffic
摘要:
通过增加对向车道上的成对车辆之间的相互作用,引入了合并中的合作。用改进的最优速度模型对两车道合并成单车道的情况进行了仿真。在到达合流区之前约30秒,两条车道上的车辆调整其车头时距,以在合流车辆的前方和后方创造安全距离。合作防止从自由流到同步流的过渡,发生正常合并,合并区域是足够大的,总的传入流不超过最大可能的单车道流量。所考虑的合作类型不需要远距离车辆对车辆通信。
英文摘要:
Cooperation in merging is introduced by adding interactions between pairs of vehicles in opposite lanes. Simulations with an improved version of the modified optimal velocity model are done for two lanes merging into a single lane. For ~30 seconds prior to reaching the merge region, vehicles in both lanes adjust their headways to create safe distances in front of and behind the merging vehicle. Cooperation prevents the transition from free flow to synchronous flow that occurs for normal merging, provided the merge region is sufficiently large and the total incoming flow does not exceed the maximum possible single-lane flow. No long-range vehicle-to-vehicle communication is required for the type of cooperation considered.
