The influence of vehicle distribution models on packet success probability on a three lane motorway

This paper evaluates the influence of vehicle distribution models on the packet success probability when used for vehicles sending data to a base station near the motorway. Four statistical models for the distribution of the vehicles on a three lane motorway are analyzed and compared with the results obtained when using real vehicle measurements. The measurements are split into three traffic conditions: queueing traffic with low speed, heavy traffic with small average headways and light traffic. The distribution models are used to calculate packet success probabilities using Rice distribution, capture effect and a single slope path loss model. The results show that, depending on the desired accuracy, fixed vehicle positions or exponential distributions can be chosen
