交通路口信號燈設(shè)計,畢業(yè)論文,共52頁,20222字。
摘要
交叉口是道路網(wǎng)中道路通行能力的“隘路”和交通事故的“多發(fā)源”,為此,必須解決交通擁擠現(xiàn)象,減少車輛在交叉口等待時間。而解決這些問題主要是通過提高交通燈的循環(huán)效率即找到交通燈的最優(yōu)相位個數(shù)來實現(xiàn)的。同時信號相位設(shè)計是交通信號燈設(shè)計的首要步驟,直接影響到交叉口交通流運行的安全性和交叉口可能提供的通行能力。通常,在十字交叉路口,只需設(shè)置紅、綠兩色的交通信號燈即可保持正常的交通秩序,而在多叉路口需設(shè)幾種顏色的交通信號燈才能即使車輛相互之間不碰撞,又能達到車輛的最大流量。本文通過對多叉路口幾何特性的分析,運用圖論的知識和回溯著色法,通過引入圖論中“頂點著色”的概念,將城市路口交通信號相位方案設(shè)計歸結(jié)為其交通道路模型圖的頂點著色問題。

ABSTRACT
The intersection is the “bottleneck” of the road network’s traffic capacity and the “Multi-happening” of traffic accident. So, we hand to solve the crowed phenomenon of traffic and reduce the waiting time of vehicle. However, the key to solve these problems is that we should increase the efficiency of traffic lights’ cycle, in other words, finding the optimal number of traffic lights’ phase. Furthermore, designing the signal phase is the first step to design the traffic lights, which influence the safety of the intersection’s traffic operation and the capacity of the intersection’s access that can provide. Generally, at intersections, people would set red and green traffic signal to keep the usual traffic order. However, on the multiple intersections, it needs several traffic signals that can make vehicles don’t collide each other. In this paper, we analyze the geometric features of multiple intersections, then we apply the graph theory and the backtrack algorithm coloring. By quoting the concept of “vertex coloring”, finally we change the design of multiple intersections’ signal phase program to the problem of vertex o coloring.
Keywords:Multiple intersections, Graph theory, Backtrack algorithm coloring,signal phase program
