基于泊松过程的校园车辆调度模型研究

基于动态交通分配原理,根据校园学生出行特点,利用泊松过程研究校园的车辆调度方案,建立了校园车辆调度模型。通过将非齐次泊松过程离散化为分段的齐次泊松过程,描述了学生出行人数随时间推移而动态变化的过程,以此为基础求解出具体的车辆调度方案,并对该模型进行了模拟。模拟结果表明由本文模型得到的车辆调度方案效果良好。

A model of campus vehicle scheduling based on Poisson process

Based on the principle of dynamic traffic assignment,the campus vehicle scheduling with Poisson process according to the travel characters of campus students has been studied. The non-homogeneous Poission process was approximated by discrete method to some homogeneous Poission process,and the travel status of students were described. The campus vehicle scheduling model was built and simulated based on the Poission process. It is shown by the outcome in the simulation the proposed method works very well.
