Abstract:
The Texas Department of Transportation (TxDOT) currently maintains a Traffic Signals Manual. Originally published in 1999, this manual provides a guide and reference for handling requests for traffic signals on the designated State Highway System. This product is proposed as a new chapter in TxDOT's Traffic Signals Manual. It provides guidelines for installing, operating, and maintaining ramp control signals on TxDOT roadways. Ramp control signals are highway traffic control signals that have been installed to control the flow of traffic onto a freeway at an entrance ramp or at a freeway-to-freeway ramp connection. They control the rate of release of vehicles entering the freeway from the ramp to one or two vehicles at a time, thus promoting more consistent and uniform flow of traffic entering the freeway and more efficient use of the existing freeway capacity. The product also provides a ramp control signal authorization form, a ramp control signal removal authorization form, and suggested freeway performance measures.
