Derby City Council are sealing the order for the speed limit changes associated with the A52 Wyvern Transport Improvement scheme on Thursday 27th February 2020, with the speed limit changes becoming effective on Friday 28th February 2020.
Works to install the associated speed limit signs and average speed cameras will commence on Tuesday 25th February 2020 starting on the eastbound carriageway. These works are expected to be completed by the end of spring.
The route has a poor road safety record and in a five year period prior to June 2018 the Police recorded 107 collisions on the A52 between the County boundary and Pentagon resulting in 162 casualties. Of these, two were fatal, nine resulted in serious injuries and the remainder involved slight injuries.
Taking into account these issues the speed limit will be reduced from the national speed limit to 50mph between Pentagon and the trunk road boundary at Spondon. This would mirror the current 50mph speed limit on Raynesway.
Highways England control the A52 east of the Raynesway junction and beyond the city boundary. Highways England have also recognised the road safety problems along this route. To address these concerns they are currently considering a reduction in the speed limit to 50mph. This is considered advantageous given the collision history, particularly around ‘Spondon bends’ and the sub-standard nature of the road (in accordance with current design standards). Additionally, from a drivers point of view extending the 50mph speed limit to include the Spondon flyover will provide greater understanding and compliance.
The Police indicated that they would be unwilling to support a reduction in the speed limit without suitable enforcement measures being in place. There are a number of options available but due to the high speed nature of the road and following initial discussions with Highways England, average speed cameras are considered the most appropriate option. Evidence suggests that average speed cameras result in higher compliance and fewer prosecutions and that drivers travel more smoothly with improved network resilience and air quality benefits. On other routes average speed cameras have helped to reduce collisions and in particular those where people have been killed or seriously injured.
