Abstract [en]

This paper presents the results of a microscopic traffic simulationstudy of the potential effects of an overtaking assistant fortwo-lane rural roads. The overtaking assistant is developed to supportdrivers in judging whether or not an overtaking opportunitycan be accepted based on the distance to the next oncoming vehicle.Drivers have been found to consider this to be a difficultpart of an overtaking manoeuvre. The assistant’s effects on trafficefficiency, driver comfort and road safety have been investigatedusing traffic simulation. The results indicate that this type overtakingassistant can provide safety benefits in terms of increasedtime-to-collision to the next oncoming vehicle during overtakingmanoeuvres. This safety benefit can be achieved without negativeconsequences for traffic efficiency and driver comfort. A driverassistance system that supports the distance judging part of overtakingmanoeuvres can therefore contribute to improved trafficconditions on the two-lane rural roads of the future.

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.
