Versatile Model for Simulation of Rural Road Traffic

Download

In many countries the road mileage is dominated by rural highways.For that reason it is important to have access to efficienttools for evaluation of the performance of such roads. For otherroad types, e. g., freeways and urban street networks, a wealth ofmicro-simulation models is available. However, only a few modelsdedicated to rural roads have been developed. None of thesemodels handles traffic flows interrupted by intersections or roundabouts,nor are the models capable of describing the traffic flow onrural roads with a cable barrier between oncoming lanes. Theseare major drawbacks when Swedish roads, on which cable barriersand roundabouts are becoming increasingly important, aremodeled. Moreover, as new areas of application for rural roadsimulation arise, a flexible and detailed model is needed. Suchapplications include, among other things, simulation of driver assistancesystems and estimation of pollutant emissions. This paperintroduces a versatile traffic micro-simulation model for the ruralroads of today and of the future. The model system presented,the Rural Traffic Simulator (RuTSim), is capable of handling allcommon types of rural roads, including the effects of roundaboutsand intersections on the traffic on the main road. The purpose ofthe paper is to describe the simulation approach and the trafficmodeling used in RuTSim. A verification of the RuTSim model isalso included. RuTSim is found to produce outputs representativeof all common types of rural roads in Sweden.
