Traffic Modeling and Analysis

TQC utilizes the latest techniques and software available to conduct traffic simulation modeling and analysis.

The latest versions of Synchro and VISSIM as well as other traffic simulation models are used to analyze traffic flow characteristics on intersections, street networks, corridors, interchanges and highways.

These analysis are used for the determination of optimum traffic signal timing for isolated signalized intersections and coordinated traffic signal systems. The analysis are also used to review existing geometric alignments, or future geometric changes to intersections, street corridors and highway interchanges.
