Abstract [en]

The interest in in-vehicle Advanced Driver Assistance Systems(ADAS) is increasing. New systems such as Adaptive Cruise Controlsand Collision Avoidance Systems are currently introduced ata rapid pace. ADAS can both substitute and complement traditionalinfrastructure based safety improving countermeasures. Toexploit the full potential of these systems, it is necessary to estimatethe systems future impact already at early developmentstages. This paper presents a traffic simulation framework foranalysis of the aggregation of individual driver/vehicle behaviourdue to ADAS to effects on the traffic system. Application of thesimulation framework is exemplified by a study of centre line rumblestrips on rural roads. The effects of physical milled rumblestrips are compared to the effects of “virtual” in-vehicle rumblestrips for both alert and sleep deprived drivers. The use of trafficsimulation made it possible to study the combined impact ofchanges in drivers’ free driving speed, reaction time and overtakingbehaviour. Indications that the different rumble strips have animpact on average journey speeds were found amongst the simulationresults. Changes in safety indicators that can be related tochanges in overtaking behaviour were also observed.

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.
