CPRE commissioned consultants Transport for Quality of Life Community Interest Company (TfLQ) to examines the impacts of road schemes on traffic, the environment, the economy, road safety and land use.

This study draws upon evidence of short-term impacts (between one and five years after scheme completion) from over 80 road schemes, published by Highways England1 through its Post-Opening Project Evaluation (POPE) process. This is supplemented by long-term evidence from four road schemes that were completed between 13 and 20 years ago: the A34 Newbury Bypass, M65 Blackburn Southern Bypass, A46 Newark – Lincoln dualling and A120 Stansted to Braintree dualling.
