Adaptive Cruise Control (ACC) is assumed to have a potentialto improve quality-of-service and safety and to reduce the environmentalimpact of the road traffic system. This paper use vehicletrajectories from traffic simulation to study impacts of ACCon vehicle acceleration and deceleration rates. The analysis isbased on traffic simulations with car-following models includingACC functionality and driver behaviour in ACC-equipped as wellas standard non-equipped vehicles. The simulation results showthat ACC can improve the traffic situation in terms of reduced accelerationand deceleration rates even though macroscopic trafficproperties may remain uninfluenced. This supports the hypothesisedpositive road safety and environmental effects of ACC. It isalso established that the results are largely dependent on the assumptionsmade regarding driver behaviour in ACC-equipped andstandard vehicles. It is consequently crucial to include appropriateassumptions regarding driver behaviour in traffic simulation basedanalyses of ACC.
