Abstract	Vehicular ad-hoc network (VANET) is supposed to provide urgent broadcasting services, which can enhance driving safety greatly. This paper proposed a two-directional VANET model for analyzing the performance of broadcast with enhanced distributed channel access mechanism in 802.11p MAC layer, with the hidden terminal problem and message strict priorities considered. Moreover, an M/M/1 queue is used to calculate the broadcast delay of each access categories (AC). The analytical model is presented and then validated through simulations. Based on the solutions of the proposed analytic model, the average packet delay of low-priority and the Packet Delivery Rates of high-priority of each AC can be accurately evaluated.
