Speed Reduction While Accommodating Emergency Vehicles with Small Inner Track Widths

The City of Regina implemented speed cushions, which are new to Regina, on Whelan Drive. The high speeds and proximity to an elementary school and two parks contributed to why Whelan Drive was selected to be the location of this pilot project. Speed cushions were used instead of conventional speed humps due to the need to provide unimpeded access for emergency vehicles with small inner track widths while slowing down passenger vehicles. Regina Fire Department raised concerns regarding the time they lose driving over speed humps when responding to emergencies. Conflict studies have been done to monitor the number of individuals that improperly use the speed cushions in order to determine if they are causing any additional problems. Speed studies have also been performed to measure the impact of the speed cushions on the 85th percentile, which is the speed which 85% of vehicles are travelling at or below. The studies were performed in the fall, winter and spring since installation in order to measure the ongoing success of the project. Minor improvements can be made to make this design even more safe and desirable, such as additional signage, increased enforcement of crossing the centre line, and filling in one of the gaps. With ongoing monitoring and implementation of some key suggestions, this pilot project could be a positive solution to speeding problems on residential and collector streets, yet still provide the fast and safe passage of emergency vehicles.
