【Abstract】:Taking the intersection of Huaishang Avenue and Jiefang Road as the research object, aiming at the traffic problems existing in the intersection, based on the full investigation, taking the traffic flow as the control unit, this paper puts forward the appropriate control strategy, designs the control plan through the independent optimization control algorithm of the signal group, and then applies it to the implementation. Finally, it summarizes the application effect, and compares and analyzes the average vehicle load before and after the optimization of the intersection The speed and average delay data show that the control strategy proposed in this paper can significantly improve the traffic efficiency of the intersection and solve the practical problems of the intersection. The case provides method guidance and reference for signal control optimization of urban signalized intersection.

隨着国内经济的发展和城镇化水平的提升,人民消费结构的逐渐升级,汽车保有量不断增长,并呈明显上升的趋势。随之而来的,是城市交通面临的巨大挑战,交通拥堵、安全问题成为常态,也增加了交通管理者的管理成本。道路交叉口作为道路交通网的结点枢纽[1],解决交叉口问题,是治堵、缓堵、保障交通安全的关键。合理地对交叉口进行信号优化,能够大大地提升道路通行效率,同时,由区域面统筹到交叉口点的控制[2],是解决区域交通问题的重点。
截至2018年4月底,蚌埠市全市的汽车保有量为35.2万辆,市区汽车保有量为16.4万辆,交通拥堵问题也日益凸显。为交叉口制定匹配的信号控制策略[3],自然成为交通管理的要点。……
