Traffic Speed Survey April 2013

There was a traffic survey undertaken in Grampound in April by CORMAC using a covert radar device fitted to a lamp post in Fore Street.

Councillor Bob Egerton highlighted the report at the recent council meeting. The report RadarClass A390 Grampound Site 2 April 2013 is now available on the Parish Council website.

The survey was conducted between 16th and 22nd of April this year and the device analysed traffic 24 hours a day in both directions of travel. Over 60,000 speed observations were made.


It found that about 80% of the traffic was within the speed limit and that the 85th percentile was about 31 mph.

It reports that 15% of traffic is above 31 mph (about 9000 vehicles per week), and 1% is over 40 mph (in both directions on the hill). The highest average speeds seemed to be on Sunday where 1:20 vehicles were travelling at more than 10 mph above the speed limit.
