EIA and ES transport chapters.
Traffic and transport chapters for Environmental Statements, prepared in line with the IEMA guidelines and coordinated with the noise, air quality and other specialists.
Also known as: ES Transport Chapter, EIA Chapter, ES Chapter, Environmental Statement traffic and transport chapter
What’s included.
If your scheme needs Environmental Impact Assessment, the traffic and transport chapter sets out the likely significant effects on people using the roads, footways and cycle routes. The IEMA Environmental Assessment of Traffic and Movement guidelines (2023) are now the standard approach.
- Scoping and screening input
- Baseline conditions and sensitive receptors
- Construction and operational effects
- Severance, delay, safety and amenity assessment
- Mitigation and residual effects
- Cumulative effects with other schemes
- Traffic data for noise and air quality teams
- Non-technical summary text
Straightforward, proportionate, agreed early.
IEMA-based
We apply the 2023 IEMA guidelines, including the screening rules on traffic and HGV increases, so the chapter stands up.
One data set
The same traffic figures feed the Transport Assessment, the noise chapter and the air quality chapter, so nothing contradicts.
Honest significance
Effects are described plainly, with mitigation where it is needed and not invented where it is not.
Questions we get asked
What triggers a full traffic assessment in an ES?
IEMA screening rules usually look at links where traffic or HGVs rise by more than 30%, or 10% in sensitive areas. We apply them and agree the approach at scoping.
Do you provide traffic data to other consultants?
Yes. We issue a single agreed data set for noise and air quality modelling.
Can you work with our EIA coordinator?
Yes. We fit around your programme and their chapter template.
