Transport Scotland reviews Environmental Statements (ES) with regard to the potential environmental impacts associated with increased development traffic on the Trunk Road and its adjacent receptors (such as communities) in line with the Guidelines for the Environmental Assessment of Road Traffic (Institute of Environmental Assessment).
The impact of traffic is dependent upon a wide range of factors including: volume of traffic, traffic speeds and operational characteristics and traffic composition. Additionally, different types of development will attract different levels and types of traffic, therefore, different environmental impacts.
The review process focuses on any direct physical impacts and on the environmental effects associated with increased traffic on the Trunk Road network and includes consideration of the following effects:
- pedestrian/cycle amenity
- pedestrian delay
- driver delay
- infrastructure wear and tear
- noise and air quality
The most common issues associated with EIA projects are:
- requests for new junctions onto the Trunk Road network or to use the network for the movement of abnormal loads; for example in the case of a quarry or wind turbine application. In such circumstances, we ask the applicant to provide the design of any proposed alteration to the Trunk Road or for a Route Assessment report in the case of transporting abnormal loads.
- environmental effects associated with increased traffic. The focus here is to establish the significance (in accordance with the environmental regulations) of the effects and consider the appropriateness of any mitigation measures.
- noise & vibration and air quality impacts, which are dealt with under PAN 1/2011 Planning and Noise and the Design Manual for Roads and Bridges For further information on the assessment of the environmental impact of road traffic associated with new developments please see the Guidelines for the Environmental Assessment of Road Traffic (Institute of Environmental Assessment).
We welcome early discussion on EIA requirements.
