British Columbia study offers cost analysis of multiple pedestrian crosswalk engineering treatments.
The current pedestrian crossing warrant model for British Columbia divides treatments into three main categories: signing and markings, special crosswalks, and pedestrian signals. Special crosswalks initially meant overhead beacon systems but that section now includes in-road warning lights (IRWL), rectangular rapid flashing beacons (RRFBs) and LED-enhanced signs.
Estimated costs for the various treatment types are depicted in the table below.
|Sign and Markings||Less than $10,000|
|Solar RRFB system||$35,000|
|AC RRFB system||Line power location dependent + operation cost|
|Solar IRWL + RRFB||$50,000|
|AC IRWL + RRFB||Line power location dependent + operation cost|
|Overhead Beacons or RRFBs (mast arms)||$60,000 + operation cost|
|Overhead Beacons + IRWL
(solar may be available)
|$80,000 + operation cost|
|Pedestrian or half signal||$125,000 + operation cost|
After standard signs and markings, solar-powered RRFB systems were found to be the cheapest to install and operate when compared to overhead beacons. Most IRWL sites tested included overhead beacons; however, IRWL systems may be solar powered and may operate with RRFBs instead. Such a system will significantly reduce the installation cost since no overhead mast arms are required. Additionally, long-term operational costs are also reduced because of the off-grid power provided by solar generation.
