Abstract
Improvement of traffic safety by cooperative vehicular
applications is one of the most promising benefits of vehicular
ad hoc networks (VANETs). However, to properly develop such
applications, the influence of different driving parameters on the
event of vehicle collision must be assessed at an early design stage.
In this paper, we derive a stochastic model for the number of
accidents in a platoon of vehicles equipped with a warning collision
notification system, which is able to inform all the vehicles about
an emergency event. In fact, the assumption of communications
being used is key to simplify the derivation of a stochastic model.
The model enables the computation of the average number of
collisions that occur in the platoon, the probabilities of the different
ways in which the collisions may take place, as well as other
statistics of interest. Although an exponential distribution has been
used for the traffic density, it is also valid for different probability
dis ...
