Intervention Plan for Improving Intersections in Saint-Jérôme

The city of Saint-Jérôme is experiencing sustained growth that is putting its traffic signaling infrastructure under strain. With the expansion of residential and commercial areas, it became essential for the city to regain control of its assets by establishing a clear, accurate, and detailed inventory of its entire traffic light network.

Beyond modernization and optimization, the primary objective was to obtain a precise overview of the condition of the equipment to better plan maintenance, replacements, and long-term improvements. This initiative would not only improve traffic flow and safety but also ensure more efficient and sustainable management of signaling infrastructure.

Our Intervention

Main Objectives:

• Conduct a complete inventory of intersections to assess the condition of existing equipment and identify intervention priorities.

• Develop a 10-year intervention plan, including detailed budget estimates and technical recommendations.
• Propose innovative solutions to optimize traffic flow, reduce congestion, and enhance safety.
• Strengthen connectivity and intelligent coordination through modern equipment.

Project Phases

Phase 1: Inventory and Updates

One of the fundamental steps of this project was to establish rigorous asset management by conducting a comprehensive inventory of the city’s signaling infrastructure. This phase ensured a complete and up-to-date view of the equipment to improve intervention planning and priority management.

• Updating electrical plans: Verification and documentation of installations to ensure that each intersection is compliant and properly recorded.
• Detailed inventory of each intersection: Precise listing of traffic lights, control cabinets, controllers, and other equipment.
• Equipment condition assessment: Technical analysis of traffic lights, detection, and control systems to identify malfunctions and obsolete equipment.
• Creation of a maintenance and prioritization table: Ranking intersections based on intervention urgency, considering their condition and impact on traffic and safety.

Thanks to this first phase, the city of Saint-Jérôme now has a centralized and reliable database, allowing it to better anticipate its maintenance and equipment replacement needs while optimizing budgets.

Phase 2: Inspection, Diagnosis, and Traffic Analysis

This phase aimed to deepen the understanding of the existing infrastructure through field studies and detailed technical analyses.

• Fieldwork: Inspection and data collection at 50 intersections.
• Analysis of traffic flow and safety conditions at each intersection.
• Evaluation of traffic light coordination to detect inconsistencies and optimize cycles.
• Data collection on phasing and signal timing, including wait times and traffic impact.
• Queue and congestion analysis to identify critical areas.
• Preliminary risk assessment for road users, particularly pedestrians and cyclists.
• Verification and update of manual equipment plans, especially for intersections lacking documentation.

Classification and Prioritization of Interventions

Each intersection was evaluated and classified based on:

• The urgency of necessary interventions.
• The direct impact on traffic flow and safety.
• The remaining lifespan of existing equipment.
• The efficiency of current configurations: assessment of phasing plans and verification of whether the equipment is optimal for managing current traffic.

This analysis helped identify intersections requiring immediate intervention and those that could benefit from progressive optimization.

Phase 3: Analysis of Strategic Corridors and Recommendations

The analysis of signaling infrastructure identified specific challenges and allowed for tailored solutions to optimize traffic management, modernize equipment, and improve user safety.

Optimization of Phasing and Timing Plans

• Adjusting signal cycles to reduce wait times and improve traffic flow.
• Revising intersection priorities based on observed traffic flows.

Traffic Light Coordination

• Synchronizing signals on strategic corridors to reduce congestion.
• Integrating adaptive solutions that adjust coordination in real-time based on traffic conditions.

Equipment Modernization and Proactive Management

• Replacing aging infrastructure to ensure optimal operation.
• Standardizing systems to facilitate maintenance and extend equipment lifespan.
• Deploying remote supervision solutions for real-time monitoring and optimized maintenance.

Safety and Prioritization of Vulnerable and Emergency Users

• Integrating illuminated signs and dynamic signaling to enhance pedestrian visibility and safety.
• Implementing preemption systems to optimize emergency vehicle passage.

Advanced Technologies and Intelligent Traffic Management

• Adopting advanced detection solutions to better account for vehicles and pedestrians.
• Utilizing artificial intelligence and data analysis for more efficient network management.

These recommendations form a flexible and evolving roadmap, allowing the city of Saint-Jérôme to gradually optimize its signaling network while integrating cutting-edge technologies tailored to urban mobility challenges.
