The relation between traffic flow and lane width

In The Netherlands lanes are reduced in with if they are used as a peak-hour lane or during road works. The research in this project focusses on the traffic flow during normal circumstances, but with reductions in lane width. First, the differences between situation without and with reduction in lane width are investigated on aspects as driving behaviour, flow, speed, density and capacity. From these differences, the relation between traffic flow and the width of lanes will be estimated.

Secondly, the results of the first part are used to evaluate the microsimulation model FOSIM, to which recently a module for small lanes was added. The assumptions made in the model will be checked and recommendations for improvement will be given.
