| Abstract: | The traffic operation characters and main problems of Shanghai urban freeway were analyzed. The isolated ramp metering scheme was carried out in the key bottleneck position. Based on the on-ramp of Luochuan Road in Shanghai City, the main road, ramp traffic condition, and related ground traffic condition were analyzed. The ramp control scheme was designed according to the specific situation in Luochuan Road. The conditions to apply project control threshold value and ramp adjustment scheme were particularly discussed. Finally, the effect of the scheme was appraised. This design scheme can improve the current traffic situation of congestion, and thus promote the efficiency of the freeway. |
