INTRODUCTION Since 2001 when the European Transport Commission set out its guidelines for the next decade in road transport policy, and which were reaffirmed in the midterm review communication of 2006 [1], there has been a major effort on the part of all European countries to improve road safety. As one fruit of this effort, there arose more than 60 projects in the EU 6 th and 7 th Framework Programs under the e-safety umbrella. E-safety initiative includes research projects based on communications between vehicles or vehicle-infrastructure so as to reduce the number of vehicle accidents. Intelligent cooperative systems based on wireless communications will play a key role in the development of new advanced driver assistance systems (ADAS). As a matter of fact, the development of dedicated short range communications (DSRC) as a reserved band for the communications among vehicles [2], suggests the importance of applying communications systems to increase the safety in the roads. In this line, the trend for the future is based on control stations so as to coordinate the traffic within a zone [3]‐[5]. However, wireless communication systems present, as main drawback, delays that can cause failures in the control system since the information has to go from the vehicle and the infrastructure to a control station and then come back to the vehicles and devices in the infrastructure to take the best action. Most of road fatalities are due to an excessive speed, so the delay
