城市道路机动车交通分配一般使用的是高峰小时机动车起讫(0D)矩阵,提出一种基于高峰小时发生率调查的高峰小时机动车OD矩阵预测方法.直接调查各类用地的高峰小时机动车发生率以及其出行种类,可以进行高峰小时的小区出发到达量(OD)预测以及到出行产生吸引(PA)的转换.在使用高峰小时机动车PA进行出行分布预测之后,利用调查得到的出行种类比例进行高峰小时机动车PA矩阵到0D矩阵的转换,进而得到高峰小时机动车OD矩阵.
Peak hour vehicular OD matrix is used in urban road network traffic assignment. A method to forecast peak hour origin destination (OD) matrix based on trip generation is presented. The forecasting of peak hour vehicular OD and its transition to producing and abstracting(PA) can be carried out by the survey of peak hour vehicular trip generation of different land utilization and its trip composition. After the PA trip distribution forecasting, the transition of PA matrix to OD matrix can be done by the method.
