摘要在一些道路交叉口，机动车流量很大，而且道路跨度较大，对行人过街造成一定程度的困难，特别是弱势群体，例如老年人，残障人士等，若等待时间过长，心理上易造成烦躁从而闯红灯过街，导致违章情况的发生，且最小绿灯时间对机动车信号配时会产生很大干扰。若设置一些交通设施，如过街天桥、地下通道，虽能将行人与机动车完全隔离，但要在一定条件下才能实行，并需要较高的费用。因此我们考虑二次过街方式，其能有效减少行人过街时间，减少人车冲突，提高行人的过街安全，并且可以随道路条件的变化而变化，成本花费较少，可以有效缓解交通拥堵的问题。

Title The design and simulation analysis of two pedestrian crossing signal scheme
Abstract
In some road intersection，vehicle flow is very large, and the road of big span， causing a certain degree of difficulty on the pedestrian crossing， especially vulnerable groups， such as the elderly， the disabled and so on， if the waiting time is too long， the psychological easy cause irritability to red light running across the street， led to the illegal situation occur, and the minimum green time greatly the interference of the motor vehicle signal timing will. If the set some traffic facilities， such as pedestrian bridges， underground passage， although the pedestrians and vehicles are completely isolated， but must implement can under certain conditions， and require higher cost. Therefore， we consider two crossing mode， which can effectively reduce the crossing time， reduce vehicle conflict, improve the pedestrian crossing safety， change and can follow a road condition， cost less， and can effectively alleviate the traffic congestion problem.
This paper first behavior characteristics of pedestrian crossing the street two times is analyzed，and according to gender and age were analyzed. At the same time on the two crossing facilities structure and setting standards of research. In addition，also the design method of pedestrian crossing the street two times of signal timing and makes a thorough study.
This paper takes Nanjing city of East Zhongshan road and Longpan Road intersection as an example，a preliminary analysis is carried through
investigation of pedestrian crossing，pedestrian illegal number partition type，on the intersection of two street in the perspective of the improvement，and effectively improve the traffic efficiency and the traffic quality of the intersection，greatly easing the traffic here pressure. And through the VISSIM simulation of intersection，in the process of simulation，through the acquisition of pedestrian crossing time，queue length and delay data，to further prove the correctness and rationality of the scheme.
