The business case for the Derby NO2 Roadside Scheme

Derby City Council submitted the full business case to Government on 26 March 2019, detailing how it would tackle and reduce roadside NO2 emissions in the city.

We provided a traffic and network management solution to tackle the one area of exceedance identified on Stafford Street, in response to prescribed limits determined by EU legislation.

A significant modernisation of the Council’s urban traffic management system and several junction design changes were proposed:

• Changes to the junctions at either end of Stafford Street to limit traffic flow at the exceedance point.
• Changes to improve capacity at the Ashbourne Road / Uttoxeter Old Road junction and on Friar Gate by providing alternative route choices.
• Traffic management measures to support the use of alternative routes, such as Uttoxeter Old Road.
• Enhancement of the city’s Urban Traffic Management and Control (UTMC) system, enabling more dynamic management of traffic flows, with emissions reduction and air quality objectives prioritised alongside the need to manage the network, in particular at peak periods and when incidents occur on the network.
• Improvements to the local highway network, including re-waterproofing and resurfacing of a bridge over a former railway line, to ensure medium-term network availability, resilience and reliability. 

The traffic management measures outlined in the business case were approved by the Secretary of State on 13 May 2019 and a ministerial direction was issued.

We welcomed the outcome of the Ministerial Decision and approval of the traffic management scheme and implemented the changes in 2022. And, we remain fully committed to meeting our legal duty to reduce roadside NO­2 emissions at the site of exceedance.

Derby City Council will continuously monitor Stafford Street until 2025.
