Intelligent selection system of adaptive optimal route based on GIS and grey-fuzzy decision theory
-
摘要: 为满足驾驶员路线选择的个性喜好和保障道路畅通, 在分析影响驾驶员路线优选因素的基础上, 提出了路线优选指标体系, 引入灰色模糊决策理论, 建立了基于GIS的智能路线优选系统, 采用动态数据更新的Web信息共享方法, 保证了路线优选的适时性。实例应用结果表明: 系统具有直观、形象的交通图形显示功能, 使驾驶员能够根据自己偏好与地图提示, 准确地找到最优路线, 提高了自适应路线优选的效率与可信度。Abstract: In order to satisfy drivers' individual interests road traffic, the influence factors of drivers' route selection were analyzed, an optimum index system of route selection was designed, grey-fuzzy decision theory and GIS technique were introduced, an intelligent selection system of adaptive optimal route was put forward, and Web information share method of dynamic data update was adopted to ensure the dynamic property of route selection. Applying result shows that the system can display traffic figures intuitively and visually, driver can well and truly find optimal driving route traffic figures, and the efficiency and dependability ot enhanced. 2 tabs, 7 figs, 15 refs.
