My idea is important because of climate change, congestion and general well being.
To improve traffic flow.
For some bizzare reason HGV's limited to 56mph when the national speed limit is 60mph. Since this was introduced coingestion has increased by over 20%.
Answer – change the law so that all vehicles travelling on a motorway must be capable of achieiving the national speed limit (with exceptions for abnormal loads, cranes etc)
Traffic calming has increaeed congestion and increased pollution by approx 30%.
Answer – vehicles only work efficiently when the engine is running consistantly. Traffic calming measures such as speed humps etc create a stop start senario which increases fule consumption and subsequently pollution massively. On a trail survey average fuel consumption of 30mpg on combined driving was reduced to 20mpg on city driving. That is a massive 30% increase. Multiply that nationaly and it a wonder we are not all dead !
