  In this paper, we study vehicular communications (VCs) at intersections, in
the presence of interference over Nakagami-m fading channels. The interference
are originated from vehicles located on two perpendicular roads. We derive the
outage probability, and closed forms are obtained. The outage probability is
derived when the destination is on the road (vehicle, cyclist, pedestrian) or
outside the road (base station, road side unit). We compare the performance of
line of sight (LOS) scenarios and non-line of sight (NLOS) scenarios, and show
that NLOS scenarios offer better performance than LOS scenarios. We also
compare intersection scenarios with highway scenarios, and show that the
performance of intersection scenarios are worst than highway scenarios as the
destination moves toward the intersection. Finally, we investigate the
performance of VCs in a realistic scenario involving several lanes. All the
analytical results are validated by Monte-Carlo simulations.
