Vehicle-to-infrastructure (V2I) and vehicle-to- vehicle (V2V) communications find extensive applications, particularly for congestion avoidance and road safety. However, development of such communication systems require accurate modeling of the wireless channel. This paper presents a methodology to simulate cross-road environments involving vehicular traffic. We propose a novel modeling approach for vehicular traffic based on a non-stationary one-dimensional Poisson arrival process which is represented by a M/M/infty queuing model. The joint ray-tracing of the stationary scatterers such as surrounding buildings along with stochastic modeling of mobile scatters such as vehicles reduces simulation time significantly, and yields relevant statistics of channel parameters with a minor compromise in accuracy.
