Methodological proposal for generating a Pedestrian Crosswalk Safety Index (PCSI)

We propose a Safety Index of pedestrian crosswalks along main roads in Mexico for reducing fatalities and to improve crossing conditions. In order to identify and weight the index criterions, about 53 state of the art documents were reviewed; a non- probabilistic survey was conducted (N=1000); in situ observations were carried out and a multi-criteria analysis method was implemented. A final index was developed. It has 19 criterions arranged within 5 macro-criterions related to the infrastructure, design and operation conditions of the crosswalk. One of each criterion was weighted and assessed over a 0 to 1 range scale. The pedestrian crosswalk safety index intends to be a useful tool for public stakeholders, which allow them to easily assess crosswalk qualities as well as to identify crosswalk issues in order to be improved.

The final step is to validate the index by surveying in situ random and representative sample of crosswalks where fatalities happen, and confront them with the 2015 geocoded fatalities database.
