Abstract

The newly developed Connected Cruise Control-system aims to reduce the level of congestion at Dutch highways by the provision of real-time driving advices towards car drivers. The advices have the intention to let car drivers adapt their driving speed, headway or driving lane in order to create a more homogenous traffic flow that is less sensitive for disturbances that cause congestion. The CCC-system is currently in a premature developing phase, leading to uncertainty regarding the possible effects of the system on traffic safety. In this paper the traffic safety effects of the system are estimated with the help of a microscopic traffic simulation model. The results of the simulation study indicate that high penetration rates of the CCC-system result in a reduction of the level of congestion and in a reduction of potentially dangerous Time To Collision-conflicts. However, the simulation results also indicate that there is a slight increase in safety critical Time To Collision-conflicts; leading to the conclusion that the traffic safety effects of CCC should be investigated in more depth before the system gets market deployment.
