Abstract


With the continuous progress of human society, and science and technology development , urban transport problems has become the important issues of common concern to governments around the world , is increasingly affecting people's daily life and socio-economic development . Travel by the growing demand for traffic information tends to be diversified and personalized , intelligent traffic guidance system based on the demand for public transportation services has become a research hotspot . The development and construction of a dynamic intelligent traffic guidance system can publish dynamic traffic information to travelers and managers , reporting traffic dynamic guidance of the travel plans and planning driving routes , can effectively relieve the pressure of road congestion and improve traffic efficiency . Article in -depth understanding of the service-oriented architecture (Service-Oriented Architecture, SOA) based on comprehensive consideration of various traffic information needs , SOA-based intelligent traffic guidance system . The paper first analyzes the theory and SOA-related system , a SOA architecture for intelligent traffic guidance system . The architecture as an entry point to SOA reference framework using Web Service technology , SOA loosely coupled with transparency . Then , the paper expand demand analysis of the characteristics of the system as well as function , clear the need to implement the functionality of the system , and its modular design , how to design a system service introduced in detail , focusing on the analysis of traffic data and database design . The realization of the system , the paper shows some of the major features on the system to make the test . Chapter compared several classic shortest path algorithm , combined with the actual characteristics of the road network , improved classic A * algorithm to solving actual traffic induced route . Dynamic route guidance this study is to provide to meet the real-time traffic information for the purpose of the integration of the service-oriented architecture , research of intelligent traffic guidance system based on SOA . Not only to solve the existing traffic information island , and achieve real-time traffic route guidance function , improve the road network capacity , so a variety of traffic travel efficient convergence and coordination , and ultimately achieve the double increase of the level of service and economic benefits .
