Traffic Data Acquisition Application

Traffic Data Acquisition is among one important tasks in ITS. All the on-line or historical data are vital for the design and planning for the traffic management strategy. The traffic data acquisition device normal consists of two parts: the sensor and the controller. The controller links with the central through wire-line connection and send back the data collected from the sensor. However, installation of the wire-line relates to huge engineering efforts and the maintenance of fixed lines has always been difficult. There will be more problems to get wire-line connection in remote areas. When

the communication line goes down, data is lost unless a data Logger is further installed.

connection is achieved by the plug & play of wireless module and no change is necessary on the original detecting device. And only simple application is required at the central to access the terminal data. The total system implementation is accomplished within 3 weeks.
