Abstract [en]

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.

Abstract [en]

Microscopic traffic simulation has proven to be a useful tool for analysis of varioustraffic systems. This thesis consider microscopic traffic simulation of rural roads andthe use of traffic simulation for evaluation of driver assistance systems.

A traffic simulation modelling framework for rural roads, the Rural Traffic Simulator(RuTSim), is developed. RuTSim is designed for simulation of traffic on singlecarriageway two-lane rural roads and on rural roads with separated oncoming trafficlanes. The simulated traffic may be interrupted by vehicles entering and leaving themodelled road at intersections or roundabouts.

The RuTSim model is applied for analysis of rural road design alternatives.Quality-of-service effects of three alternatives for oncoming lane separation of anexisting Swedish two-lane road are analysed. In another model application, RuTSimis used to simulate traffic on a Dutch two-lane rural road. This application illustratesthat the high level of model detail of traffic micro-simulation may call for use of differentmodelling assumptions regarding driver behaviour for different applications,e. g. for simulation of traffic in different cultural regions.

The use of traffic simulation for studies of driver assistance systems facilitateimpact analyses already at early stages of the system development. New and additionalrequirements are however then placed on the traffic simulation model. It isnecessary to model both the system functionality of the considered driver assistancesystem and the driver behaviour in system equipped vehicles. Such requirements canbe analysed using RuTSim.

In this thesis, requirements on a traffic simulation model to be used for analysisof road safety effects of driver assistance systems are formulated and investigatedusing RuTSim. RuTSim is also applied for analyses of centre line rumble stripson two-lane roads, of an overtaking assistant and of adaptive cruise control. Thesestudies establish that the assumptions made regarding driver behaviour are crucialfor traffic simulation based analyses of driver assistance systems.
