Outline business case
Derby City Council submitted the outline business case to government on Monday 25th February, which set out the preferred option to combat exceedances of the legal NO2 level in the city.
The Council’s further localised refinement of the national modelling process, has confirmed that Derby has only one location on its network where NO2 concentration exceedances are predicted in 2020 if no action is taken. This is on Stafford Street, which forms part of the inner ring road around Derby city centre.
| Location | Predicted level of roadside NO2 in 2020 if we take no action |
|---|---|
| Stafford Street, near to its junction with Friar Gate | 49.3µg/m3 |
The outline business case put forward a traffic management solution to tackle the one area of exceedance identified on Stafford Street and included several junction design changes and a significant modernisation of the Council’s urban traffic management system.
