  In this paper, we study the performance of millimeter wave (mmWave) vehicular
communications (VCs) using non-orthogonal multiple access scheme (NOMA) at road
intersections, since there areas are more prone to accidents. We study the case
when the intersection involves two perpendicular lanes, we then extend the
study to an intersection with several lanes. The transmission occurs between a
source, and two destinations. The transmission experiences interference
originated from a set of vehicles that are distributed as a Poisson point
process (PPP). Our analysis includes the effects of blockage from buildings and
vehicles at intersections. Closed form outage probability expressions are
obtained. We show that as the nodes reach the intersection, the outage
probability increases. Counter-intuitively, we show that the non line of sigh
(NLOS) scenario has a better performance than the line of sigh (LOS) scenario.
Finally, we compare the performance of mmWave NOMA with OMA, and we show that
NOMA offers a significant improvement over OMA mmWave vehicular networks. The
analysis is verified by Monte-Carlo simulation.
