Trees planted in Norfolk speed cut scheme

Research shows the trees could knock up to 3mph off drivers' speeds
A scheme which aims to stop drivers speeding through villages is up and running in Norfolk.
More than 160 trees have been planted on rural roads in in Martham, Mundesley, Overstrand and Horstead in an "experiment" to stop drivers speeding.
It is hoped the trees will create an "avenue effect" and encourage drivers to slow down.
Oak, field maple, birch and hornbeam have been planted in the £70,000 trial.
All 163 trees, and 1,443ft (440m) of hedges in Martham, are expected to be planted by the end of March.
All four villages taking part in the trial had a history of speeding problems, Norfolk County Council said earlier.
Ahha sound engineering - albeit in about 10 yrs time !
Making drivers think is excellent.
I like the idea of it funnelling as you approach the town (Martham).

It will make the road potentially more dangerous and less with winter shadows and protection (less snow, but more localised micro-climate so possibly more ice or damp ....)
