Revision of PV² based pedestrian crossing warrants in India using clustering techniques

Abstract

Pedestrian crossing warrants are guidelines used around the world for safe pedestrian crossing movements. Pedestrian volume (P) and vehicular volume (V) are the most widely used parameters in crossing warrants. PV2-based pedestrian crossing warrants are used in India, Iran, and UK. These warrants were first reported in UK in 1987 and adopted in India in 1988. The registered vehicles in India have increased 10 times since then. Moreover, the pedestrian crossing warrants recommended in India by IRC 103:2012 do not identify the type of crossing facility to be installed in case, the warrant criteria is satisfied. To re-examine the existing warrants, the maximum hourly pedestrian and vehicular flows estimated from the data are used as the upper bounds for developing the PV2 matrices. K-means clustering was used to obtain the new PV2 threshold values. The proposed warrant charts can be used to identify the type of crossing facility that is suitable for a location based on the observed peak hour pedestrian and vehicular volume.
