An Intelligent Control System for Detecting and Progressing Platoons at Isolated Traffic Signals (0-4304-S)

A significant number of the Texas Department of Transportation's (TxDOT's) signalized intersections operate under isolated control. At many of these signals, it is not uncommon for an approaching platoon of vehicles from an upstream signal to face a red signal when it arrives at the stopbar. Often, these platoons are forced to stop because of a single vehicle on one of the conflicting approaches. This condition results in aggravation, excessive stops, and higher delay to motorists in the platoon. In this project, Texas Transportation Institute (TTI) researchers developed and field-tested an intelligent traffic control system for detecting platoons approaching a traffic signal and for progressing detected platoons.
