Urban traffic hotspots analysis, mainly by means of the wireless sensors installed in all kinds of transportation on the urban traffic situation of mobile sensor network monitoring, analysis of the citys traffic hotspots. In this paper, based on the XianYangShi bus system, designed and developed a urban traffic simulation platform, through the vehicle-mounted mobile sensor network system for the implementation of various bus lines in xianyang city track, record every bus path, through the hot search algorithm, to calculate the traffic hotspots in downtown. The urban traffic simulation platform, has realized the path tracking of bus lines, and then realize the detection and management of city traffic hotspots, the traffic administrative department of the implementation of traffic management and traffic provides a good decision-making basis.
