摘要: 城市交通中,交通管理部门需要动态掌握群体性的出行规律,其获取方法亟待解决。为此,基于交通流的空间分析,提出了一种能够描述群体性动态出行规律的典型行车路线理论。在对交通流进行空间数据挖掘和动态OD("O"起始点,"D"目的地)分析的基础上,通过行车路线中热点路口的生成、备选路线的追踪获取以及可选路线的模糊聚类分析,从而获得能够表征群体性动态出行规律的城市交通典型行车路线。最后,以杭州市交通路网为例,开发了典型行车路线智能获取系统并进行了实验验证,结果表明,典型行车路线理论及其算法能够较真实地描述城市路网中群体性的动态出行规律,为交通部门的交通控制与诱导、公交路线规划等提供了决策参考。

Abstract: It is significant for the urban traffic administration to obtain the dynamic travel regularity of colony vehicles with the same or similar route. Unfortunately, there is no such an efficient method yet. To solve the issue,considering the traffic route linked by nodes including tiny traffic zones and traffic intersections, the typical colony route theory based on Spatial Analysis is proposed to describe the travel regularity of colony vehicles. Furthermore an algorithm to acquire the typical colony route is researched based on dynamic Origin-Destination (OD) analysis. Firstly, by means of the statistic of spatial traffic flow parameters collected by GPS or shooting-identifying device deployed at the road intersections, the hot traffic spots can be hunted. Accordingly, the candidate routes can be traced by calculating the occupancy proportion of the routes concerning these hot traffic spots. Secondly, resorting to fuzzy clustering of traffic intersections during the analyzing course of the similar candidate routes, the tiny zone nodes and the colony-route set can be obtained. At last, the typical colony route containing traffic intersections and tiny traffic zones can be generated by sorting the colony-route set. Finally, based on the proposed typical colony route theory coupled with the algorithms, the software is developed to hunt for typical colony route automatically. Take the experimental traffic grid in Hangzhou City as an example, two typical colony routes is successfully acquired. According to the result of manual static OD investigating and manual statistical surveying, both typical colony routes are in accordance with the real travel regularity. Comparing with the previous manual methods, the proposed solution does not only demonstrate better performance in efficiency but also be able to reflect the dynamic route regularity of vehicle colony travel just in good time at urban district. The research could facilitate the urban traffic administration to adopt proper countermeasure to eliminate traffic jam and traffic trip pressure. Referring to the dynamic travel regularity of colony vehicles, the urban traffic administration could publish the traffic navigation message concerning the whole typical colony route at the route’s key intersection, and improve the deployment of the bus station or the route plan of urban public bus.
