| 中文摘要: |
| 动态路径诱导(DRGS)是智能运输系统ITS研究的一个重要方面,它的核心在于如何利用实时的交通信息,找出一条考虑司机路径选择行为的"最优道路",减少车辆在道路上的逗留时间,进而改善城市交通.但这仅仅给出了一条基于单目标的"最优"路径供司机采用.采用改进后的K-最短路算法,提供多条具有不同属性的路径供司机选择,从而更符合实际情况. |
| 英文摘要: |
| The study on Pynamic Route Gvidance System(DRGS) is an important aspect in the field of Intelligent Transportation System(ITS). The core of the study is to find a "best route"for drivers according to the current traffic information. As a result the travel time can be saved and the traffic congestion can be avoided. This method can give drivers a single "optimal" path to follow. After the adoption of the improved K-shortest path algorithm, we can offer a number of routes with different features to drivers,which will tally with the as tual situation better. |
