Research On Planning And Positioning Of VMS

With the rapid development of economy, the big city' s congestion has become more serious. Among the all ways of solving the city congestion, traffic management is by far more important than the only way of building road and bridge. Advanced traffic management system is one of the most important measures for traffic management, while VMS (vehicle message system) is the important equipment of advanced traffic management system. Through releasing the related message, the VMS will guide the vehicle to the most reasonable path, avoiding the partial congestion and thus balance the network traffic flow.Nowadays, the VMS technology has become mature, so the VMS positioning will play an important role on the whole DRGS (Dynamic Route Guidance System). As VMS positioning is mainly depended on the experience to carry on, this article will induce the theories of the DRGS, combining the actual circumstance of Guangzhou City, and put forward a set of ways of VMS positioning. Mainly analyzing from the customer need , network layout and traffic flow and so on ,we will apply fuzzy theories to the positioning decision based on the traffic characteristics of Guangzhou. During the positioning, we will consider of a few important circumstances such as city exit and so on, finally ,we take an important road — Tianher road of the eastern region of Guangzhou as a example to carry on demonstrating the road positioning. This article will apply the above-mentioned method to get the end project that a whole city VMS positioning order finally, in order to be carried out in a specific way in the days to come.
