In this paper an analysis is described of microscopic traffic behaviour when entering a motorway. The study is part of the DRIVE II ROad Safety Enhancement System (ROSES) project. In this project, an integrated infrastructure based and on-board road and weather monitoring system is developed and tested. A simulation model has been built, which incorporates the characteristics of vehicle performance and the driver control. For the subsequent phases of the entering procedure, a driver behaviour model has been designed. One specific road layout is investigated, while traffic situation and road friction are varied in a number of scenarios. Simulation results show that in slippery conditions a reduction of the mainstream traffic speed is required in order to maintain a proper safety level. The results of the study can be used in advanced traffic control and in-vehicle safety systems. (A)
