• Abstract:
  In this study, the effectiveness of the I-35W variable advisory speed limit system on the improvement of the traffic ; flow was evaluated with the real traffic data. The analysis results indicate there was significant reduction in the ; average maximum deceleration and also the traffic time reliability was substantially improved during a peak hour ; period. Based on the assessment results, an enhanced version was developed to be able to reflect more effectively ; the time-variant road traffic conditions in determining the variable speed limits in real time. The coordinated ; adaptive metering strategy, developed in the previous phase of this research, is also enhanced and implemented in ; the field in this research. The field test results of the new metering system with the 100 NB corridor indicate ; substantial improvements in both the mainline and ramp traffic performance compared with those from the old ; stratified algorithm.
