Monitoring of vehicles on roads and tunnels is performed with the use of RFID tag technology. Unfortunately, the reliability of the current RFID-based approaches is lacking. This paper explores the possible reasons for this by performing a propagation study using two scenarios. The first scenario is a gantry based tag reading system as is typically used in tolling applications, and the second is an in-road reader scenario. The second scenario mitigates a majority of the propagation problems experienced by the first scenario. By reducing these propagation problems, lower cost RFID tags can be used for road monitoring applications. Deploying such a system which is both lower in cost and higher in reliability can allow for more ubiquitous monitoring which in-turn can allow more informed decisions to be made on future road, bridge and tunnel infrastructure.
