Operating Guidelines for TxDOT Ramp Control Signals

摘要

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, including installations financed by federal funds and installed on the numbered State Highway System. It describes the steps necessary for installing a traffic signal, from project inception through construction and final disposition of records. It contains five chapters: Introduction, Requests for Traffic Signal, Traffic Studies, Operational Considerations, and Traffic Signal Projects. It also contains two appendices: one that contains the forms necessary to warrant and install a traffic signal on TxDOT roadways and another for determining the need for traffic control at school crossings.
