基于模糊决策跟驰理论的计算机仿真

对于车辆跟驰过程中模糊的、不确定性的、难以进行精确数学描述的行为过程,探讨采用模糊控制来实现。面对交通系统的诸多影响因素,寻找最优解决方案解决各种交通问题,在现实交通环境中难以实现,应用计算机技术进行交通仿真。利用计算机仿真技术,结合模糊控制规则给出高速公路上车辆跟驰行为的一种仿真,仿真结果表明,用模糊推理模拟驾驶员的行为是可行的,并且通过模糊推理控制后车的速度,后车能够以安全距离跟随前车安全行驶。

The Computer Simulation of Vehicle-Following Based on Fuzzy Decision

It is hard to describe drivers＇ behavior with precise algorithm because of its fuzzy and uncertain minable characteristic when following a leading car.Therefore,we will consider fuzzy control.With increasing.of relative factors influencing traffic system,we always try our best to search the most cost-effective solution in order to settle all kinds traffic problems,however,in the actual circumstances,there is a faint hope to achieve it,because some fields requires massive capital investment and the unsafe factors in some fields continue to exist.In this case,it is the most effective way to apply computer technology to traffic simulation.In this paper,we simulate car-following in the highway with the principle of fuzzy control by computer simulation technology,simulation results reply that it is feasible to simulate driver＇s action with fuzzy reasoning,which can control the following car＇s speed well so that following car can drive safely to leading car by a safe distance.
