Movable Vehicle Activated Sign

A Movable Vehicle Activated Sign (MVAS) is a road sign usually triggered by the speed of the vehicle which can be moved from site to site.  On the 23rd November 2017 the MVAS was installed in Botley Road (Chesham to Ley Hill direction).

Four groundscrews have been installed, three in Ley Hill (Jasons Hill, Botley Road and at the bottom of Kiln Lane) and one in Latimer (Codmore Wood Road).  The MVAS will be moved between the four sites on a regular basis.

Due to the high speeds recorded on Rushmere Lane, Orchard Leigh when conducting Community Speed Watch Checks the Parish Council decided to install a fifth groundscrew.  This was installed in September 2018.

The MVAS will flash a speed warning for vehicles exceeding the speed limit (30mph).  It will also record data that can be used to monitor the volume of traffic during a particular period as well as on a daily basis.  More importantly it will give us information on the speeding cars (the speed they are travelling and at what time of the day).

We have already had:

  • Several cars travelling over 60mph on Botley Road, The Green and Jasons Hill.
  • Friday 25th November 2017 between 8 – 9am, 72% of cars were travelling over the speed limit down Botley Road in the direction of Ley Hill School.
  • one car travelling at 80mph from Ley Hill to Chesham
  • Since 1st January 2018 we have had 11,985 cars speeding at 40mph or over. 724 cars were travelling at 50 mph or over and 50 of those cars were travelling at 60mph or more.
