Abstract


With the rapid development of society , more and more people have vehicles , making traffic problems has become a major problem of our existing . By modern technical means to manage urban transport, traffic mobility and flexibility , improve the utilization of transport facilities , to maximize the operational efficiency of the existing transportation system , the development of intelligent transportation systems (ITS) that can ease urban traffic congestion situation . Intelligent transportation system is an effective way to solve the traffic problems , and wireless location technology can provide more information for the intelligent transportation system . In addition, the design and development of the LBS system based on GIS technology traffic travel the corresponding query service . In this paper, the wireless location technology in the intelligent transportation systems , research several different positioning technologies , such as TDOA positioning technology , the basic genetic algorithm is applied to TDOA technology , hybrid genetic algorithm is applied to TDOA technology , GPS positioning technology and differential GPS positioning technology, and design the application GPS pseudo- range differential position positioning model of the design . The same time, to study and to achieve a common GIS platform LBS ( Location based service ) - based platform , the platform for intelligent transportation systems to provide certain services , this paper also design the external interface of the LBS platform designed LBS business platform and design and Implementation of GIS in the LBS platform . GIS research , focusing on the function module design, packaging and GIS spatial database , this paper study design at the same time , but also a part of the function module coding . Finally, the article briefly describes the structure of the intelligent traffic analysis system based on the orientation of the phone , and a summary of the design and description of the structure of the public transport management system and traffic travel advice and services subsystem .
