Rating scales

In most schemes, each crosswalk of the intersection is evaluated separately. Items and point values assigned differ on the rating scales now available.

Rating scale items typically include
  • pedestrian usage,
  • intersection and traffic conditions, and
  • a number of special conditions.
A rating scale used in developing a transition plan may be slightly different than one used to determine responses to individual requests.

Pedestrian usage
Pedestrian usage
  • Proximity to alternate crossings
  • Proximity to transit stops
  • Proximity to key facilities used by all pedestrians
  • Proximity to facility for persons who are blind
  • Need to cross - frequency of use by requestor
Intersection and traffic conditions
Intersection and traffic conditions
  • Intersection configuration
  • Width of crossing
  • Traffic signal phasing
    — Leading or lagging vehicular turn phasing
    — Leading pedestrian interval
    — Split phasing
    — Exclusive pedestrian phasing
  • Traffic volume
  • Vehicle speed
  • Presence of pedestrian push buttons
  • Right turning traffic
Special conditions
Special conditions
  • Pedestrian accident records
  • Unique circumstances
  • Poor visibility of pedestrians (obstructions, parking lanes, curved street, crosswalk location)
  • Orientation and mobility instructor comment/evaluation
Prioritizing individual requests
A rating scale used in prioritizing requests for APS at specific crosswalks may include factors such as:
  • Number of requests for APS at crosswalk
  • Frequency of use by pedestrians requesting APS
It may be appropriate for a jurisdiction, in response to an individual request in an area with extremely low pedestrian counts, to install an APS specifically meeting the requirements of that individual. That APS may not otherwise conform to requirements for new construction, or for installation in a more traveled pedestrian area.

Examples of rating scales currently in use are available in PDF format below. A rating scale will be validated as part of NCHRP 3-62 and will be available by winter 2004.
