摘 要近年来,国内一些大城市的交通拥堵问题愈发严重。信号灯控制能有效解决城市交通拥堵问题。随着经济和科技的高速发展,信号灯在各个十字交叉路口已相当普及,但是如何科学有效地管理信号灯,让路口的通行车辆最大化,使路口车辆的停留时间最少成了一个需要解决的问题。在不同的交叉路口,车辆的实际通行情况各不相同,即使在同一交叉路口,各个时段的车辆通行情况也各不相同。信号灯管理需要根据当地路口的实际通行情况时时进行调整优化。本论文先根据十字路口的通行情况推导出红绿灯和通行车量之间的数学公式,然后实地调查某交通路口高峰段各方向车辆的实际流量 ,最后根据数学公式提出信号灯的优化方案及其评价方案。71280
In recent years, some domestic big city traffic congestion problem has become more serious. Signal control can effectively solve the city traffic congestion problem. With the rapid development of economy and science and technology, signal lamp in each intersection has been quite popular, but how to scientifically effectively management signal lamp, allow intersection traffic maximization, the residence time of the intersection of the vehicle at least become a problem need to be solved. At the intersection of different, the actual capacity of the vehicle is different, even in the same intersection, each time the traffic situation is also different. Signal management according to the actual needs of local traffic intersection constantly optimize. In this paper, first according to the crossroads of the passage of the push export traffic lights and traffic volume between the mathematical formula, and then the field investigation the actual flow of a traffic intersection peak period in the direction of vehicle, and finally put forward some optimization scheme of signal lamp and evaluation program according to the mathematical formula.

1.1研究背景
近年来,我国机动车和驾驶人迅猛增长,近五年机动车年均增量1500多万辆,驾驶人年均增量2000多万人。到2014年为止,我国拥有机动车2.64亿辆,其中汽车占58%;机动车驾驶人超过3亿人,其中机动车驾驶人占82%。[1]论文网
汽车保有量达1.54亿辆,新注册量和年增量均达历史最高水平。随着我国经济社会持续快速发展,群众购车刚性需求旺盛,汽车保有量继续呈快速增长趋势,2014年新注册登记的汽车达2188万辆,保有量净增1707万辆,均为历史最高水平。近五年来,汽车占机动车比例从43.88%增加到58.62%,交通出行结构发生了根本性改变,群众迎来了汽车时代。 解决城市交通问题的合理化建议:http://www.youerw.com/shuxue/lunwen_80907.html
