Vehicle-to-vehicle (V2V) communication based collision avoidance systems detect if two vehicles are on a collision course, which are particularly useful in the absence of line-of-sight (LOS) owing to buildings, roadside infrastructures, and road bending. This paper presents an empirical study of V2V propagation channels in two suburban cross-road scenarios, where vehicles are either moving in the same direction and separate each other, or passing each other in opposite directions at the crossing. The quasi-stationarity interval is characterized using correlation matrix distance (CMD). Angular dispersions are found to be significantly affected by the type of cross-road and the presence of a LOS. By comparing the results of the different cross-roads, it is found that the angular dispersion is large in the first type of cross-road. By contrast, in the second type of cross-road, small angular dispersion is observed due to the road bending and obstruction by roadside trees.
