UTISP: An Urban Traffic Information Portal Based on WebGIS

Abstract

Publishing and delivering traffic information generally depend on message board and public radio service in China, which usually sends out static information without dynamic interaction between the services and the users. With the development of WebGIS and its successful application, it is possible to introduce the Web-based multiple architecture into the traffic information system. Currently, most WebGIS portals only provide static information in words and figures without any significant improvement in dynamic aspect, which is a very important requirement for traffic information system. We develop an urban traffic information portal for dynamic information updating and responding, which is based on the fast growing rich Internet application and WebGIS technology. The portal can not only provide the real-time information but also can interact with users for more specific. This paper introduces the multi-layer architecture used in our project. Reusable services related with GIS services are designed and encapsulated as portlet. We briefly introduce some implements and optimization at the end of this paper.
