Evaluating the effectiveness of signal timing optimization based on microscopic simulation

Previous studies have shown that there are inconsistencies between the assessments of signal timing plans based on the results of optimization tools that use macroscopic simulation models and the assessments of the same plans based on microscopic simulation models. The studies show that the signal t...

The studies show that the signal timing plans, identified to be optimal by the optimization tools, are determined to be not optimal and sometimes do not perform well according to microscopic simulation assessments.
