Traffic study at the right of the level crossing

Level crossing No. 310 is a critical node For the town of Collonges-au-Mont-d'Or, due to its role as the main crossing of the railway line.
Today, the PN is managed manually by a gate guard, and pedestrian crossing is prohibited, creating a Major urban break And a deterioration of accessibility at the station.

Under the project management of SNCF Réseau, the Metropolis of Lyon wanted to have up-to-date knowledge of traffic flows and multimodal issues at the municipal level.
Explain has thus conducted a comprehensive study divided into two main phases:

1. Phase 1 — Diagnosis and Data Collection:
   • Achievement of automatic counts And of directional counts.
   • Driving a origin-destination survey throughout the town.
   • Analysis of the entry and exit points of the municipality, taking into account truck restrictions.
2. Phase 2 — Multimodal analysis and recommendations:
   • Study of current operation of the level crossing and its interfaces with the road network.
   • Assessment of crossing needs for all modes, especially for pedestrians and cyclists.
   • Proposal of ways to optimize the functioning and requalification of the sector.

The results made it possible to draw up a complete diagnosis of traffic and urban cuts, the basis for future work to optimize the crossing.

‍

The objective of this mission was to provide the Métropole and SNCF Réseau with comprehensive knowledge of flows and uses around the level crossing.
Explain was supposed to:

• quantifying traffic and identifying the main transit routes;
• analyze the security and accessibility issues for all modes;
• Suggest operational guidelines making it possible to improve the cohabitation between road, pedestrian and rail flows.

The study allowed the Métropole de Lyon and SNCF Réseau to have a reliable and homogeneous database on traffic in Collonges.The results highlighted room for improvement in terms of safety and pedestrian continuity, and made it possible to prioritize actions to be taken in the short and medium term. Thanks to a multimodal and pragmatic approach, Explain brought a objective and operational lighting on the challenges of a complex sector with high railway constraints.

The diagnosis carried out in Collonges-au-Mont-d'Or constitutes a reference for rail crossing security projects, reconciling safety requirements, accessibility and improved mobility.
