The Société de la Rocade L2 de Marseille (SRL2) engaged AMOG to conduct a literature review of the state of the art in road tunnel air quality improvement technology in support of design and construction of a series of cut-and-cover road tunnels as part of the Rocade L2 (A507) project in Marseille, France.
AMOG investigated the options employed in road tunnels around the world for improving air quality, with a focus on their effectiveness in decreasing pollutants and their related financial costs and greenhouse emissions.
The areas of investigation undertaken by AMOG included:
- Air pollution and contaminant concentration limits adopted for ambient air and for road tunnel projects internationally
- Air quality improvement strategies that are applicable to road tunnels, including ventilation and contaminant removal technology
- Contaminant removal technologies that can be applied to road tunnels
- International experience of use of contaminant removal technology in road tunnels
And studies on the:
- Cost effectiveness of and removal efficiency of real road tunnel applications of containment removal technology
- Alternatives to air filtration technology that can be utilised to improve tunnel air quality
- Air quality monitoring instrumentation, with a particular emphasis on the specific demands presented by measuring in road tunnels
