【摘要】：考虑车辆到达类型(可表征交叉口信号联动质量),基于交通波理论重构交叉口车辆运行轨迹,进而应用机动车比功率模型(VSP)开发了信号控制交叉口排放估计算法,并结合HCM 2010延误模型,分析了不同到达类型下信号周期和流量对交叉口排放及延误的影响及排放和延误的博弈关系.结果表明,在相同条件下,交叉口联动质量越好,交叉口车均排放和延误越小;周期增大,车均排放减小,延误先减小后增大,其中,交叉口联动质量越好,基于延误最小的最优周期越大;车均排放对流量的变化较不敏感,而延误受流量影响较大.
[Abstract]:Considering the type of vehicle arrival (which can represent the signal quality of intersections), the vehicle trajectory is reconstructed based on the traffic wave theory, and the vehicle specific power model (VSP) is used to develop a signal-controlled intersection emission estimation algorithm. Based on the delay model of 2010, the effects of signal cycle and flow rate on the emission and delay of intersection and the game relation between emission and delay are analyzed. The results show that under the same conditions, the better the quality of intersections, the smaller the average emission and delay of intersections, and the greater the cycle, the smaller the average emissions, and then the greater the delay, and the better the quality of intersections. Based on the minimum delay, the larger the optimal period is, the less sensitive the average vehicle emission is to the flow change, but the more the delay is affected by the flow rate.
