BACKGROUND
The Maricopa Association of Governments Pedestrian Plan 2000 includes two tools
to help assess where pedestrian facility improvements are most needed in the MAG
Region and specific recommendations that would create a greater sense of pedestrian
comfort. These tools were expressed as roadway design performance guidelines and
quantified through the following models:
- Pedestrian Latent Demand Model
- Roadside Pedestrian Conditions Model
The models provide statistical support to what can sometimes seem intuitive. In
instances where statistical support is helpful or required to justify spending on
pedestrian improvements, the models can be deemed critical. However, the logarithmic
models can be considered complex and are best understood by engineers that routinely
perform this type of work. Other projects may be justified by using a more intuitive
approach to determine priorities and degrees of pedestrian accommodations. Still
others may require no justification; decision makers need only be directed to guidelines
that fit their particular location and condition.
DECISION MAKING SCENARIOS
This section provides three decision making scenarios when determining
pedestrian facility need.
- When to use the models as presented in the Pedestrian Plan 2000
- When to use an intuitive approach
- When to simply make a determination of your condition, and then design accordingly
One methodology is provided for assessing project priority for Scenarios #1 and #2.
Scenario 1) When statistical verification is required to support a pedestrian
improvement priority and/or a level of pedestrian accommodation: Apply the Pedestrian Latent Demand Model and the Roadside Pedestrian Conditions
Model and apply the corresponding level of pedestrian accommodation corresponding
to: Safety, Comfort or Destination as defined in this document.
