Should Council wish to implement the speed limit reduction in phases with the cost and effort spread out over multiple years, or to implement a speed reduction only in specific areas (e.g. neighbourhoods where resident support is highest), Option 2 would not be suitable.

Feedback was received from Windsor Police Service and the Provincial Offenses Office; both indicated that, of the three options, Option 1 would be preferable from an enforcement perspective. Windsor Police Service indicated that without additional measures to encourage compliance, the increased enforcement demand associated with any of the three options would increase police effort and cost associated with speed enforcement.

The capital costs for Option 1 and Option 3 are within 4% of each other. The high-level cost estimates provided in this report do not provide enough precision to confirm which of these two options has the lower cost.

Time Required for Implementation

Option 1 & Option 3

For Option 1 and Option 3, the minimum time to begin implementing 40 km/h speed limit reductions is in the order of 6 months. This time period would allow for the required amendments to Traffic By-law 9148, utility locates, and production and installation of an initial set of signs.

The total time to implement Option 1 or Option 3 for residential neighbourhoods City-wide would depend on several factors. If carried out entirely by City staff at current staffing levels, this work would likely need to be phased over several years. Implementing either Option 1 or Option 3 City-wide in a single year would likely require hiring temporary staff at additional cost.

Option 2

For Option 2, the minimum time to implement a 40 km/h speed limit in residential neighbourhoods is approximately two years. Implementing this option in a single year would likely require hiring temporary staff at additional cost.

The City-wide default speed limit could not be changed until all major roads that would remain at 50 km/h have speed limit signs installed. This work could likely be carried out by City staff at current staffing levels over two years’ construction seasons; once these new 50 km/h signs are installed, Traffic By-law 9148 would be amended to reduce the City-wide default speed limit to 40 km/h.

Option 2 cannot be phased. It would be implemented City-wide as soon as the default speed limit is changed.
