Signal Design Manual for Diamond Interchanges (1439-6)

A comprehensive signal design of a diamond interchange is essential for its efficient operation. The design process should consider the likely operational scenarios that the operations engineer will face in the future. The signal design should also consider the requirements of the maintenance technicians at the interchange.|This design manual provides guidelines for the signal design of a diamond interchange. The manual will provide guidelines on the number controllers required, lane assignment and other geometric considerations, detector requirements, and other general considerations. General signal design guidelines should follow the "Traffic Signals Manual - Traffic Operations Division December 1999" and the Texas Manual on Uniform Traffic Control Devices (MUTCD).
