Title:

Optimal Control of Variable Speed Limits and Road Lighting Based on Predicted Short Term Socio-Economic Impacts

Abstract:

In research conducted on a 6 km rural, two-lane road section in Finland during low visibility and winter weather conditions, information on traffic and weather conditions is input to a control system that executes the optimal decision (varying speed limits and roadway lighting intensity) on each road sections. The control system minimizes socio-economic costs (vehicle, time, environmental, lighting and accident costs), while maintaining an acceptable level of service (Safety & Mobility)
