The reliability of a DSRC-link for ETC applications modelled on 5 levels of detail

For electronic payments, the communication link has to be reliable. Dedicated short range communication is a proposed solution for the automatic debiting of vehicles without disturbing the traffic flow. The reliability requirements of such a system are high, which implies that only large scale simulations with a lot of detail are effective to analyse an occasional error. In the article, a hierarchical approach is worked out that allows such simulations of the communication link with a 80% reduction of the computational effort compared to simulation with full detail.
