This project yielded three tools for allocating investments to improve pedestrian infrastructure. The tools are tailored to suburban clusters and corridors where past research has shown that the potential exists for substantial volumes of pedestrian travel. The first two tools, Pedestrian Location Identification (PLI) tools 1 and 2, help differentiate between suburban areas that do and do not have potential for pedestrian travel. The third tool, Pedestrian Infrastructure Prioritization (PIP) Decision System, supports decision-making processes to allocate investments in infrastructure improvement to areas that do have potential for pedestrian travel. The tools generally yield benefits at the policy, implementation, and scientific levels.
PLI-1 and PLI-2 focus on medium-density residential land development, areas that have been neglected in the past as locations with potential for pedestrian travel. By considering combinations of land uses that are generators and attractors of pedestrian travel, they capture the characteristics of land-use mixes that have the highest potential for substantial volumes of pedestrian trips. By using small spatial units of land-use data, they adequately capture the characteristics of actual development on the ground and, specifically, those characteristics that support pedestrian travel. The small units of data also allow a precise and accurate measurement of the land-use characteristics of the small areas that correspond to short walking distances.
PIP is a synthesis of previous efforts to identify the environmental and policy variables that affect pedestrian travel. It acknowledges three types of environmental factors known to affect pedestrian travel demand: area-wide characteristics defined by land uses and development patterns, characteristics of the transportation facilities, and policies that determine the level of support for pedestrian travel. PIP provides a complete yet flexible framework for making decisions regarding infrastructure. It allows jurisdictions to work with their own internal set of priorities.
