Many applications for inter-vehicular communication require a very specific test situation in order to be evaluated during a real world experiment. However, in the currently prevailing free-flow experiments the intended situation for the application may not occur in sufficient frequency to provide statistically significant results. In this paper, we argue that the existing experimental approach should therefore be complemented with coordinated experiments. This allows to specifically create the desired test situation. We present a methodology for such controlled experiments. The key to those experiments is the exact coordination of the participating cars' movements as well as a detailed control over all used soft- and hardware. To illustrate this methodology, we have performed an experiment with two cars that simultaneously approach an urban intersection and measured the radio transmission ranges with and without a road side unit. The results show that cars equipped with communication technology can inform their drivers about the approaching other cars up to ten seconds before a possible accident at such an intersection.
