车流到达模型的求解与仿真研究

仿真技术为解决城市交通问题提供了重要手段,精确高效的车流到达模型是成功实现交通仿真的关键。在分析车流到达模型和车头时距概率分布规律的基础上,采用反函数法求解模型的概率分布函数产生随机数,并根据求解和仿真的需要用C#编程语言构建车流产生器、车辆等数据结构并实现算法,最后利用GDI＋图形接口实现模型的仿真、检验计算的正确性和效率。

Solution to Vehicle Dispatching Model and and Simulation

Simulation technologies provide effective ways of analyzing urban traffic problems.An accurate and effective vehicle dispatching model is essential to traffic simulation.After the analysis of regular vehicle dispatch models and probability distribution of time headways,this paper uses an inverse function method to solve the associated probability distribution equation and generates random numbers.Using C# language,the proposed approach defines the data structures such as vehicle dispatching class in support of simulation and implementation of the algorithm.With the help of GDI＋ this paper simulates the model and examines the accuracy and efficiency of the algorithm.
