Improvement ramp metering
Ramp metering an important traffic management measure in The Netherlands. Around the big cities a lot of ramp metering systems have been installed to improve the traffic flow on the motorways, by controlling the flow on on-ramps by means of a traffic light. Normally, ramp metering has a positive effect on the traffic flow on the motorway and a negative effect on the traffic on the on-rmap. For the control process a standard algorithm is used, but also a number of other algorithms are possible. Therefore, the research question is: can these ramp metering algorithms be improved? And what are the impacts of these improved algorithms?
