Traffic incident aware coordination of ramp meters
Paper i proceeding, 2017

As one of the indisputable causes of congestions in motorways, traffic incidents are regarded as an important factor in reducing throughput of motorway networks. A novel model based local ramp metering method is presented in the paper by means of incident scheduled freeway traffic control solution. Traffic anomalies are captured by adequate model parameters, i.e. incident parameters that can be on-line estimated. The paper is motivated by incident scheduled ramp-meter solution to encounter real-time incident parameter information. The main idea is to use local freeway control solution triggered by available incident parameter values. The proposed approach is local in the sense of considering only non-coordinated ramp meter solution, first. Furthermore, we apply locally optimal (linearized) control solution to satisfy throughput maximization objective. The formal controller synthesis involves parameters to correct, compensate the effect of incidents.
