Vehicles speeds in Grampound reduce after installation of speed visor; but still a problem

A significant proportion of vehicles driving through Grampound on the A390 exceed the 30 mph speed limit. Monitoring carried out by Cornwall Council using Radarclass equipment has shown that there is a particular problem with westbound traffic towards the end of the 30 mph zone as the vehicles start to accelerate out of the village. Over a one-week period in January 2016, it was shown that 45% of vehicles were travelling in excess of 40 mph at this point. For full results, see Grampound speed information.

The parish council resolved to purchase a vehicle activated flashing speed visor for installation close to the junction with Old Hill. The Council bid for monies from the Grampound Community Fund (Garlenick wind turbines money) and were awarded the major part of the cost of the proposal.

In October, the visor was installed.

In February 2017, further monitoring of traffic speeds was carried out for a one-week period. The results showed that the speed of traffic coming into the village from Truro was unchanged from the readings a year earlier. However, for the traffic exiting the village and passing the newly installed speed visor, speeds were signficantly lower than a year earlier. The percentage of vehicles exceeding 40 mph has reduced from 45% to 18%. This is still far too high, but it is not quite as bad as it used to be. So, although a majority of motorists are setting off the visor display, they do seem to be taking some notice of it in terms of keeping their speeds down.
