British Columbia study offers cost analysis of multiple pedestrian crosswalk engineering treatments.
British Columbia, Canada
Summary Information
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.
