Intersection Prioritization Tool Worksheet

The
Intersection Prioritization Tool
provided through the link and available from the Traffic Safety Division was recreated from National Cooperative Highway Research Program (NCHRP) 3-62 research. The worksheets are a product of NCHRP 3-62 and are published in the
Transportation Research Record, Journal of the Transportation Research Board
, No. 1982, pp. 13-20, entitled “Development of an Intersection Prioritization Tool for Accessible Pedestrian Signal Installation”. The Intersection Prioritization Tool consists of two worksheets.
  • The
    Intersection Worksheet
    accounts for intersection characteristics and layout, signalization type, and location related to transit facilities, facilities for the visually impaired, and major pedestrian attractions.
  • The
    Crosswalk Worksheet
    accounts for the individual crossing characteristics. Each crossing at the intersection is rated based on several factors including:
    • crossing width
    • speed limit
    • geometrics
    • pedestrian signal control
    • vehicle signal control
    • off-peak traffic presence
    • availability of alternative APS
    • requests for APS installation.
The Intersection Prioritization Tool provides a method of scoring individual crossings for relative crossing difficulty to visually impaired individuals. This provides a method to compare crossings for priority for installation of APS systems. In general, if one crossing generates a high priority, it would be desirable to provide APS for all crossings at the intersection.
The detailed instructions on the correct method for filling out and completing the worksheets are available on the internet at
