The European Commission has recognized therefore C -ITS as a disruptive factor that could increase the efficiency of traffic and ameliorate its adverse effects on the environment and the economy. C -ITS have been previously tested in various European cities with a focus on signalized intersections. These services provide advice to drivers with respect to optimal behaviour under specific situations, with the purpose of increasing safety and traffic efficiency. With regard to traffic efficiency, the Energy Efficient Intersection Service (EEIS) aims at reducing energy consumption and vehicle emissions in the vicinity of signalized intersections. Hardware can be installed on vehicles (either passenger cars or trucks), and when they approach the traffic lights, fuel-efficient acceleration/ deceleration advice is conveyed to them. Hence, stops and delays are avoided reducing vehicle emissions that are associated with the start -stop episodes of the vehicle.
