摘要
通过分析实际道路交通状况,在合理假设的基础上,建立了孤立十字、丁字交叉路口、三个交叉路口线状区域以及六个交叉路口网络状区域的交通信号实时配时数学模型,利用Matlab产生满足泊松分布的车流量实时序列,按照优化目标进行了算法的设计和编程,得到了相应的数值结果,并对优化结果进行了讨论.
Based on reasonable hypotheses according to analysis of real road traffic condition, mathematical models for real time control of road traffic signals relating to single cross-shaped intersection, single-t-shaped intersection, linear regions with three multi-intersections, and net regions with six multi intersections are built. Utilizing Matlah to generate a real time sequence of vehicle flow which satisfies the Poisson distribution, algorithm are designed and compiled according to optimization objectives. Corresponding numerical sequels are obtained, and the optimized results are discussed.
