Title: Evaluation of the 20mph Speed Limit Roll Out (in Edinburgh)
Organisation: City of Edinburgh Council
Date uploaded: 5th November 2019
Date published/launched: December 1999
- There has been a statistically significant reduction in average speeds of 1.34mph across the 66 speed survey locations where the limit was reduced
- The highest reduction in average speed (-2.41mph) was for sites in rural west Edinburgh
- Findings reveal no evidence of displacement of traffic from 20mph streets to 30mph streets after implementation of the 20mph limit
- Support for 20mph is increasing but concerns remain regarding compliance
- Casualties have fallen substantially since implementation, but it is not yet possible to ascribe reductions to the 20mph limit as opposed to an overall falling trend.
The report also includes a strategy of further actions the Council may wish to
consider on streets where there may be continuing non-compliance with the new limits. Furthermore, it reviews a number of requests for streets to be added to the 20mph network and includes preliminary consideration of further pro-active expansion of the network.
