Network connectivity is a key index for designing of a vehicular ad hoc network(VANET). Road messages are propagated by V2X(includes V2V: vehicles to vehicles and V2I:vehicle to infrastructure) communications. Therefore, the access probability and connectivity probability play important roles for message dissemination. In this paper, we take the minimum safety distance between vehicles into consideration for designing of VANET. More over, we analyze the effects of the different distances between adjacent BSs, coverage radius of a vehicle and the vehicle density, respectively. The performance results get a conclusion that the safety distance has a certain effect in a VANET model.
