Title The research of the characteristics of the traffic analysis method Based on the floating car technology
Abstract
The development of floating car technology has brought great convenience for urban road traffic management systems. Research on the key technology of floating car is helpful to floating car technology to better play its role of service traffic system. This article is begin with floating car detection system、segmentation method of road、determination model of the number of floating car and the status identification for traffic. At the conclusion of the predecessors, through the theory of probability and statistics and reasoning method for exploring all aspects of key technologies. Compared to traditional detection technology, Floating car detection technology which based on GPS/GIS system have huge advantage. The internal of detection system all links mutual coordination tie, common guarantee road traffic of ordered run; The principle for road segment based on important node or sections meets the reality of road traffic, avoiding "cut peak" phenomenon to occurs; The number model based on sections coverage of floating car compared to traditional probability is more meet road traffic of characteristics. Through this research, we have reason to believe that floating car technology will play a more crucial role in road traffic system.
