In the last years the Dutch Government has investigated the performance of several prototypes of multi-lane road pricing systems. At a certain level of detail, the performance of a road pricing system depends on the traffic situation under the gantry. To be able to accurately simulate the performance of road pricing systems, we need to generate realistic traffic on an exceptional detailed level. Adding more details to a traffic generation model is not difficult; the real challenge is in validating those new features with measurements. In this project, there was a unique opportunity to validate the traffic generation model, because we had measurements from multiple independent systems. In this article we will first the explain the context of road pricing systems and the applied methodology to evaluate the technical performance of such systems, before we introduce the details of the traffic generation model that is calibrated.
