Abstract

This article considers different driving patterns at a traffic light (TLS). The motivation is to determine and improve the behavior of traffic flow at controlled intersections, given the availability of the so-called “EcoDriving” (USA) or “GLOSA” (Europe) application. This is an advanced driver assistance system that tells the driver which speed to choose in order to pass the oncoming traffic light at green. The speed is computed using information sent by the traffic light. When entering the communication range of the TLS vehicles decide at what time they will pass the halting line and follow that plan. The models of consideration either comprise speed or acceleration advisory or no advice at all, the latter in case they are not equipped with a communication device. Additionally, the cases of cooperative and non-cooperative driving across the intersection are taken into account; that is either closing the gap to the car in front or simply following a velocity that will lead to an arrival at green light. Finally, different extensions of the situation are considered: smaller random demand and a finite penetration rate. Safety criteria (brake gap) are fulfilled in any of these cases. This article presents simulation results and answers the question which driving advice strategy is best with regard to different criteria as travel time and emissions.
