The Glen Allan Traffic Calming Plan was developed in 2015 through an extensive public engagement process. View the 2015 project timeline.

These plans were updated in 2018 following a midway evaluation process that involved traffic data collection and public engagement.

Summary of resident feedback collected in 2018.

With approximately half of the traffic calming plans in Glen Allan implemented to date, traffic data collection generally shows reduced traffic speeds at most locations in Glen Allan, both at completed locations and those still awaiting the addition of features. This observed speed reduction has allowed engineers to put forward revised traffic calming plans that are more economical and less aggressive to be more in line with resident feedback.

Traffic calming features throughout the neighbourhood have been designed to work together, so the full impact of the project cannot be truly evaluated until all features are in place. Ultimately, collision records will also be a significant component of the evaluation, but this will take a few years to evaluate as collision numbers in the neighbourhood are very low.

Details of the preliminary evaluation are available in the Glen Allan Traffic Calming Project Update Report  Section 2.0 

There are three reasons traffic calming plans were changed:

• To create viable and more cost-effective alternatives to the raised intersections originally proposed.
   
• At some locations, updated cost estimates to construct the approved plan turned out to be more than anticipated due to unforeseen underground infrastructure needs.
   
• To incorporate feedback once residents had a chance to see some of the traffic calming features in place.

The proposed speed limit change to 40km/hr in Glen Allan was presented to Council, who directed it back to administration for additional review. Following additional review, and in alignment with the resident Traffic Safety Committee's recommendation, Council decided not to proceed with the speed limit reduction.

Traffic calming is being undertaken to address speed, not collisions. However, it is well established that a reduction in traffic speeds decreases the incidence and severity of collisions. This safety comes even with small speed reductions. For example, traffic safety research indicates a 10% reduction in average speed can decrease overall collision risk by 10-32%.

Speed is particularly lethal to pedestrians and cyclists. Even a small decrease in traffic speeds can have a big impact on pedestrian safety.

• 5% of pedestrians will be killed in a collision at 30 km/h
• 55% of pedestrians will be killed in a collision at 50 km/h
• 90% of pedestrians will be killed in a collision at 60 km/h
