路段感应式行人过街信号控制系统设计
路段感应式行人过街信号控制系统设计(外文翻译,论文说明书18000字)
摘 要
人行横道是生活中最常见到的路段过街设施，也是交通事故多发的地段。目前无论是交叉口还是路段上的人行横道，绝大多数都是保障了机动车的优先通行，而行人的通行权没有得到很好的保障，导致行人过街随心所欲，并不能很好地遵守交通规则，需要交警额外指挥，增加了人力负担，所以随着智能交通的发展，路段平面过街设施中的感应信号控制便成了新的研究方向。
本文对感应式信号控制所涉及的过街行人和机动车的交通特性做出总结，包括行人等待时间、过街速度、机动车车流特性等，然后通过对比目前应用的三种常见感应式控制策略，分析其优缺点，从而引出本文设计的新型路段感应式信号控制系统，并对新型系统的原理和系统组成做了详细介绍，系统包括了信息采集、感应控制和辅助系统，同时选取东南大学西门路段过街人行横道运用VISSIM进行仿真评价，对比原有定时信号控制，使机动车与行人延误达到最小。
本文设计方案充分考虑路段行人交通流运行状况，适时切换行人和机动车相位，对机动车与行人通行时间合理分配，同时对提高机动车和行人通行效率、减少行人与机动车平均总延误以及降低交通事故率，具有十分重要的意义，也为之后交叉口和特殊路段等更深层次的研究提供理论基础。 [版权所有：http://DOC163.com]

Design of Link Actuated signal control system for pedestrian crossing
Abstract
Pedestrian crossing is the most common road crossing facility in life, and it is also the area where traffic accidents occur frequently. At present, whether at intersections or crosswalks on sections, the vast majority of them guarantee the priority of motor vehicles, and pedestrians' right of passage is not well guaranteed, which leads to pedestrians crossing the street at will, can not well comply with traffic rules, need additional traffic police command, and increase the burden of manpower. Therefore, with the development of intelligent transportation, the control of the actuated signals in the road crossing facilities has become a new research direction.
In this paper, the traffic characteristics of pedestrians and motor vehicles involved in inductive signal control are summarized, including pedestrian waiting time, crossing speed and vehicle flow characteristics. Then analyze the advantages and disadvantages of the three common actuated control strategies currently applied and a new type of actuated signal control system for road sections designed in this paper is introduced, and the original of the new system is also presented. The system includes information acquisition, induction control and auxiliary system. At the same time, VISSIM is used to simulate and evaluate the pedestrian crossing in west-door section of Southeast University. By comparing with the original timing signal control, the delay between motor vehicles and pedestrians is minimized.
The design scheme of this paper fully considers the pedestrian traffic flow condition of the road section, timely switches the pedestrian and motor vehicle phase, and reasonably allocates the transit time of motor vehicles and pedestrians. At the same time, it is of great significance to improve the efficiency of motor vehicles and pedestrians, reduce the average total delay of pedestrians and motor vehicles, and reduce the traffic accident rate. It also provides a theoretical basis for deeper research such as intersections and special road sections.
Key words: Pedestrian Crossing on Section; Actuated control; pedestrian waiting time; VISSIM
