Approaching the freeway

Approaching the freeway, originally uploaded by keefer79.

The line up on 152 Street to try and get on the Port Mann Bridge. Taken at 2007:05:10 15:40:40 – so the beginning of the afternoon peak. The bridge itself is not the location of congestion, but rather the convergence of 152 St on ramp and the two or three earlier on ramps as well. The local traffic radio stations all measure the length of the queue in terms of which ramp it has backed up to. A simple ramp metering system, such as is used “downstream” of the bridge on the Coquitlam side would lengthen this queue but shorten the one on the freeway.

 On ramp meter

Most of the traffic on this stretch of Highway 1 is local commuting between North Surrey and the TriCities.
