Recent advancements in wireless communication systems along with the growth of computational power of mobile devices have considerably reduced the difference between desktop and mobile computing environments. One of these applications is Automatic Vehicle Location System (AVLS) by which one can track vehicles in real time mode. This paper reviews the design and implementation of an AVLS with a new architecture which is a client-server one. It also discusses its software which supports GPS and runs on Windows Mobile based PDAs. While the software is a powerful one, it has a user friendly graphical interface. Different programming languages are used to develop the software. All of data are transferred back and forth between users and the server through GSM technology. The server uses GSM mobile, a relatively cheap media for communication, to provide a connection to PDAs. A toolbar for ArcGIS9.2 is developed to collect and analyze these data.
