• Abstract:
  The Texas Department of Transportation (TxDOT) uses ramp control signals (also called ramp meters or ; flow signals) to control the rate at which vehicles enter the freeway. This helps TxDOT (1) promote a more ; consistent and uniform flow of traffic entering the freeway, and (2) promote a more efficient use of the ; existing freeway capacity. ; The purpose of this project was to develop guidelines and criteria to assist TxDOT decision makers in ; determining when and where to install new ramp control signals and remove existing ramp control signals ; when they no longer provide a benefit to freeway traffic. This report documents the process, procedures, and ; research used to develop those guidelines and criteria. The actual guidelines, criteria, and forms are in ; Product 0-5294-P1, “Operating Guidelines for TxDOT Ramp Control Signals.”
