Reliability is an important issue for safety-critical and traffic situation broadcast services in Vehicular Ad-hoc Networks (VANETs). The Packet Reception Rate (PRR) is a key metric to evaluate broadcast reliability. Most researches of broadcasting in VANETs focus on multi-hop routing and connection establishing, taking all one-hop links for granted. A few have focused on the reliability of one-hop in 1-D VANETs. In this paper, we evaluate the PRR for one-hop broadcast in 2-D VANETs at an intersection analytically and by simulation. Expressions of the PRR are derived with consideration of the hidden terminal problem and collisions caused by concurrent transmissions. The impact of transmission, carrier sensing and interference ranges; the distances of receivers to the senders and the density of nodes on the roads are investigated and discussed. At last, some important observations to the broadcast at an intersection in VANETs are provided.
