Traffic Study at the Municipality of Les Cèdres

Use of signage: Need for preliminary analyses

The role of our team on this mandate was to carry out a detailed safety analysis to determine if the addition of stop signs was necessary at the intersections and to analyze the mitigation measures envisaged by the municipality around Marguerite Bourgeoys school.

The installation of stop signs at intersections is governed by the road works standards, Chapter 2 — Prescription of Volume V of the Ministère des Transports et Mobilité durable (MTMD). The analysis conducted by our team consisted of verifying whether the intersections met the criteria required for the installation of stop signs. In this respect, our engineers analyzed vehicle, cyclist and pedestrian traffic counts at the intersections, identified the speeds used by motorists and studied the location and existing signage around the sectors under study. This study highlights the fact that the use of signage to optimize road safety is particularly regulated and must meet specific criteria. This solution can therefore be counterproductive depending on the context and therefore requires specific expertise before any implementation.

Traffic Study and Planning for User Safety

The municipality of Les Cèdres also wanted to improve pedestrian safety in the vicinity of Marguerite Bourgeoys School. The location of the parking spaces in front of the school and the convergence of many traffic flows at the pedestrian crossing linking the parking lot to the school led to many safety and traffic flow issues. The Intervia team therefore studied the current situation and then proposed a safe configuration that took into account the issues identified in the field and the means available to the client to address them.
