Prioritizing the Implementation of Audible Pedestrian Crosswalks

The Community Geomatics Centre (CGC) is a division of the nonprofit Sault Ste. Marie Innovation Centre, a Council Advisor located in Sault Ste. Marie, Ontario. The CGC is unique in Canada and promotes and establishes partnerships and technological means to efficiently share geospatial data, tools and knowledge amongst community organizations to create a safer, healthier and more prosperous community.
The City of Sault Ste. Marie’s population is aging rapidly, as is the population of visually impaired individuals. With the commitment to implement audible pedestrian crosswalks in the city, the CGC was approached to prioritize intersections for audible pedestrian crosswalk infrastructure implementation over time.
The CGC acquired postal codes of all visually impaired citizens through the Canadian Institute for the Blind (CNIB) and had these citizens complete a survey about the businesses and locations they visited when outside of their homes. 
This data was combined with pedestrian collision data, transit routes and stops, speed limit and intersection characteristic data. Data elements were weighted and processed to rank intersections from high to low priority for implementation. 
During the past few years, several high priority intersections have had the audible crosswalk technology implemented as determined by the suitability analysis.
