ISSTA: An integrated sensing system for transportation applications

Abstract

Traffic congestion has become an increasingly important issue worldwide. One way to mitigate this problem is to provide real time traffic information to drivers and help them make better decisions. Hence, a system with the function of traffic sensing, data aggregation and information delivery is desired. In this paper, we illustrate how we design and build such a system, which is called ISSTA (An Integrated Sensing System for Transportation Applications).This system consists of two parts: the front end is a mobile device attached to a vehicle; it can perform real time traffic and environment sensing, wireless information transmission, and interaction with drivers. The back end is a server, which stores the information collected and implements smart decision-making. In addition to this, the system supports plug-and-play for a list of sensing components. At the same time, the information collected and decision made can be easily monitored in real time through web service. Applications like real time environment monitoring and lane sensing have already been implemented and tested on this system. We have shown that it is a reliable system by itself and can provide valuable help to drivers and researchers. © 2011 IEEE.
