主干道交通管理优化设计摘要 随着地区发展，车越来越多，传统的同步红绿灯已经无法满足交通网络，传统的同步红绿灯会导致一系列问题：一边绿灯没有车通行另一边红灯堵塞，主干道时间过短，无法全部通行，导致出现堵车，降低单位时间的通行量。如果想要解决城市交通拥堵问题,我们只能从两个方面入手。第一：投入大量的人力与资金进行城市公路的修建,它的优点是能合理最大限度的提高通行量，缺点是需要长期规划时间,大量的人力、财力成本。第二：采用数学建模的思想，通过合理的红绿灯时间分配，对交通控制系统的优化。优点是能够使不改变现有道路情况下减少人力和资金消耗,实行起来不影响交通，可行性较高。我们通过数学建模，数据比较车流量大小，分析单个十字路口和一条主干道，四个交叉路口采用红绿灯不同步和同步红绿灯时, 路口通行能力的比较。发现红绿灯配时不同步能有效提高道路通行能力,使得汽车平均等待时间减少，变相的节约了能源和保护环境,减少人力财力的消耗。 关键词：十字路口 主干道 交通管理 绿波带 数学建模Optimised design of traffic management on main roadsAbstract With the development of the region, more and more cars, the traditional synchronous traffic lights have been unable to meet the traffic network, the traditional synchronous traffic lights will lead to a series of problems: one side of the green light without cars to pass the other side of the red light blocked, the main road time is too short, can not pass all, resulting in traffic jams, reduce the amount of traffic per unit time. If we want to solve the problem of urban traffic congestion, we can only start from two aspects. First: invest a lot of manpower and funds for the construction of urban roads, its advantages are to reasonably maximize the traffic, the disadvantage is the need for long-term planning time, a large number of human and financial costs. Second: the idea of mathematical modeling, through reasonable traffic light time allocation, the optimization of traffic control system. The...
