ADEL LANE – TRAFFIC CALMING – RECENT SURVEY RESULTS

As you may be aware the Council took a number of speed surveys in February 2014 prior to the installation of the traffic calming on Adel Lane in association with the development at Bodington. As promised they have repeated the surveys during January 2015, 6 months after the traffic calming was installed in July/August 2014, to see whether it is having the desired effect and whether it has had any detrimental effect on increasing the volumes on surrounding roads. The results and the conclusions drawn by Highways are set out below.

Conclusion

Volume – The above results shows an overall reduction in traffic volume on all the roads in the order of 10-20%. This could indicate a positive that some commuting drivers have stayed on the surrounding main routes (Ring Road and Otley Road).

Speed –On St Helen’s Lane, Back Church Lane and Stair Foot Lane, the average speeds have all reduced. On Long Causeway, the northbound average speed has increased from 27.8mph to 30mph; however this is still within its 30mph speed limit.

The installed traffic calming features on Adel Lane have reduced the average speed from 29.4mph to 23.6mph, a significant reduction of 5.8mph and this can be shown dramatically with the change in volume in each speed band as shown below.

 The table below also shows that the main objective, to reduce the number of vehicles exceeding the speed limit of 30mph on Adel Lane, has been achieved.

 I am still awaiting survey data from Highways on Church Lane and also further information from the police on speeding issues in the area. As soon as information is made available I will let you know.
