Temporary Traffic Management (TTM) inspections conducted between April 2023 and August 2024 during the construction of the Clontarf to City Centre Street Improvements Project, a 2.7 km infrastructure enhancement scheme for traffic routes between Clontarf and Dublin City Centre.
Location: Clontarf to Dublin City Centre, Ireland.
Client: Roughan & O’Donovan (Permanent Scheme Designer), Road Control Services Ltd. (TTM Designer), Dublin City Council.
PMCE carried out five detailed inspections of the temporary traffic management layouts during the construction phase of the Clontarf to City Centre Street Improvements Project. These inspections aimed to identify enhancements in temporary traffic management to ensure the safety of drivers, pedestrians, and cyclists.
Project Background
The Clontarf to City Centre Street Improvements Project is a transformative infrastructure initiative designed to promote sustainable travel and enhance safety for all road users. The project aims to expand cycle lanes, upgrade intersections, and integrate protected infrastructure for cyclists and pedestrians. Key elements include the creation of protected intersections to reduce vehicle speeds and ensure separation between modes of transport.
These upgrades facilitate safer travel, particularly at critical junctions such as Talbot Street and Amiens Street, while supporting the broader goals of Dublin’s active travel and climate action strategies.
Scope of the Inspection
PMCE’s inspection scope covered the following key activities:
- Site Visits: Conducted site visits during both daytime and darkness to assess the effectiveness of TTM layouts under varying visibility and traffic conditions.
- Safety Assessment: Evaluated road safety measures, including visibility, signage, and protection for vulnerable users such as pedestrians and cyclists.
- Compliance Check: Reviewed the TTM layouts for adherence to the Temporary Traffic Management Design Guidance (2019).
Key Findings and Recommendations
The inspections identified opportunities to enhance the safety and efficiency of temporary traffic arrangements. Recommendations included:
- Improved signage placement to ensure clarity for all road users, particularly at complex junctions.
- Enhanced lighting during darkness to improve visibility for pedestrians and cyclists.
- Adjustments to lane diversions to minimize disruptions for vulnerable users while maintaining vehicle flow.
These measures were critical in ensuring that the temporary arrangements aligned with the project’s broader goals of safety, accessibility, and sustainable travel.
