An extension of the feedback local ramp metering strategy ALINEA is presented to realize early-warning for downstream ramp metering and timely adjust the ramp metering rater. The new metering algorithm needs to establish some detectors monitoring the maximum traffic volume. We develop an estimation of upstream maximum traffic volume. Simulation results show the proposed ramp metering strategy is promising.
A real-time and on-line intelligent urban traffic signal control approach based on forecasting technology is proposed for the requirements of real-time traffic signal control. Considering the multiple performance indicators, the multi-phase multi-objective point-control model and line-control model are respectively constructed. By combining the characteristics of real-time urban traffic signal control,...
