With the rapid development of information and communication technologies, Intelligent Transportation system (ITS) is an efficient tool to solve urban transportation problems. For instance, Advanced Public Transportation System (APTS) based on WebGIS technology is a subsystem in ITS. APTS employs electronic, communication, and computer technologies to assist public transportation operators in raising efficiency and service level.
Taipei Bus Information and Transit System, constructed by Public Transportation Office, Taipei Government, is one of the best examples of APTS. The system can help bus users easily obtain real-time bus dynamic information and improve the convenience and users’ willingness of taking a bus. With the system, bus operators can better manage and raise the operational efficiency of their fleet by bus dynamic information and dispatch mechanism.
Using SuperWebGIS as the map server to publish maps and information about the movement of vehicles, the system is able to integrate complex transportation data from different sectors. The published information is collected from the devices on the buses and analyzed with the backend software. The devices on the buses record the movement information, such as coordinates, speeds, directions, time, etc. and send the data to the databases according to the its property. Then, various kinds of software on the back end would analyze the information and transit the analysis results to the front end for users to query.
In terms of server, the system adopts Windows Server 2003 and Linux as the platform; the system also uses Microsoft Server SQL 2005 and Oracle as the media for saving the digital data.
