Of the various advanced wireless communication technologies used for intelligent transportation systems (ITS), WiMAX has recently received much attention because of its potential to provide broadband network connectivity, large coverage areas, quality assurance, and mobile access. However, few studies have focused on the deployment, operational, and performance issues of using WiMAX networks for ITS applications in a real roadway environment. This study performed a field performance evaluation of a regional WiMAX network in West Virginia by using important network metrics, including uplink and downlink throughput, signal strength, and connectivity level. On the basis of performance analysis, this paper discusses the feasibility and suitability of a regional WiMAX network deployment for a wireless sensor-based traffic surveillance system in terms of frequency, power, and client side radio requirements. This study provides an insight into the feasibility of using WiMAX to address ITS applications. It will benefit transportation agencies and other stakeholders to support decision making in the deployment and operation of a WiMAX-based ITS network in the future.
