Signalized Intersection Engineering

The location of pedestrian signal equipment should be determined in conjunction with the curb ramp and crosswalk layout.

You must evaluate the pedestrian push buttons for accessibility triggers as well as the surrounding area for reach, range and landing requirement, when a project includes any of the following elements:

• Signalized intersections
• Rectangular rapid flashing beacons
• Pedestrian hybrid beacons
  

Accessible pushbuttons are required when traffic signal work is considered to be an alteration.

Technical Requirements

Technical guidance documents TR16-01(B) and TR16-02(B) have been incorporated into the Signal Design Manual. These documents discussed requirements for pedestrian signal equipment and audible pedestrian signals.

The following document explains maintenance work requirements.

• MG 144-03 - Traffic Signal Maintenance and Americans with Disabilities Act

Standards

• Standard Drawings Traffic Series - 400 Signals

Forms
