British Columbia study offers cost analysis of multiple pedestrian crosswalk engineering treatments.
British Columbia, Canada
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.
Treatment | Initial Cost |
---|---|
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.
