Bicycle integration of the Cardiff—Aiguillon—Renaud quays

The Cardiff—Aiguillon—Renaud wharf axis constitutes a strategic itinerary of the Nantes bicycle network, connecting Salvador Allende Boulevard to the Louisiana roundabout.
In a context of constrained areas and multiple uses, the objective of the study is to recomposing public space in order to ensure a high level of service for cyclists, while maintaining the overall functionality of the axis.

The approach led by Explain was based on a progressive and concerted methodology:

• Fine identification of available footprints on each section of the linear;
• Workshop with the services of Nantes Métropole, making it possible to define development guidelines, prioritize functionalities and arbitrate compromises when space is insufficient;
• Elaboration of layout and variant solutions, integrating general traffic, bus lines, active modes and metropolitan greening objectives in a coherent manner.

The proposals were formalized using long profiles, cross profiles and 1/1000th plans, making it possible to accurately assess the widths allocated to each use, in particular to the law of hard spots : pavement reductions, bus stops, pedestrian crossings and intersections.

‍

• Define a cycling integration with a high level of service on a structuring axis.
• Integrate all road uses in a balanced multimodal approach.
• Identify realistic and technically feasible solutions in a constrained context.
• Provide the project owner with specific elements prior to operational studies.

Thanks to the intervention ofExplain, Nantes Métropole Has a clear and shared framework to guide future developments in the axis.The integration schemes produced constitute a decision support tool facilitating the transition to operational phases, while securing development choices in light of technical constraints and political objectives.The mission contributes to strengthening the coherence and legibility of the structuring cycle network at the metropolitan level.

This project illustrates the expertise ofExplain In the design of complex cycling facilities, at the interface between mobility, public space and urban uses.
The integration study of the Cardiff—Aiguillon—Renaud docks provides Nantes Métropole robust and operational guidelines to support the development of efficient and integrated bicycle mobility.
