Standard Traffic Signal Configurations
In Standard Traffic Signal Configurations, you'll learn ...
- The five basic types of traffic signal supports
- MUTCD guidance on signal span design and signal head locations
- Issues to consider when choosing or evaluating a signal support system for a specific intersection
- The four materials typically used to construct signal poles, along with their benefits and limitations
There are significant differences from place to place in how traffic lights are mounted or positioned so that they are visible to drivers. Depending upon the location, traffic lights may be mounted on poles situated on street corners, hung from horizontal poles or wires strung over the roadway, or installed within large horizontal gantries that extend out from the corner and over the right-of-way.
This Traffic Signal Design course provides a description of the various types of traffic signal supports along with a discussion of standard arrangements for vehicular and pedestrian signal indications.
Also included in this course is a discussion of signs commonly associated with traffic signal installations and an explanation of lane use control signals. An understanding of these issues is imperative if an effective traffic signal design is to be developed.
