Proposed Approach to Lowering Speed Limits

Roads Suited to 30 km/h A review of City roads was undertaken to determine suitability for a 30km/h speed limit. Road classification plays a key role in setting appropriate speed limits. Roadways are classified based on their functional needs for mobility (moving traffic efficiently) and property access. Arterial roads are designed to prioritize high volumes of through traffic, making a 30 km/h speed limit on these thoroughfares operationally inefficient. In contrast, the majority of the City's local and collector road network is designed for residential access and are good candidates for a 30 km/h speed limit. Attachment 1 identifies the roads within the City that support lowering the speed limit to 30 km/h as these roads: • Are contained within a neighbourhood residential zone bounded by arterial roads; • Carry low volumes of traffic travelling short distances; • Have narrow pavement widths with typically no centreline; • Provide access to single-family residential land uses; • Generally, permit on-street parking; • Have a 30 km/hr speed limit in place on roads fronting schools and neighbourhood parks. Some local roads, such as Dyke Road and River Road along the perimeter dike, have the physical characteristics of a local road, however, carry higher through traffic and longer distance trips. The perimeter roads and roads within City Centre that front a mix of higher intensity land uses, are not proposed for reduced speed limits.
