On average, ten people die and 100 people are seriously injured on the roads of Great Britain each day. Two-thirds of all crashes in which people are killed or injured happen on roads with a speed limit of 30mph or less. At 35mph a driver is twice as likely to kill someone as they are at 30mph.
- Hit by a car at 40mph, nine out of ten pedestrians will be killed
- Hit by a car at 30mph, around 50 per cent of pedestrians will survive
- Hit by a car at 20mph, one out of ten pedestrians will be killed
Accident risk rises the faster a driver travels. At 25 per cent above the average speed, a driver is about six times more likely to have an accident than a driver travelling at the average speed.
At 30mph, vehicles travel 44 feet (about three car lengths) every second. Even in good conditions, the difference in stopping distance between 30mph and 35mph is an extra 21 feet - more than two car lengths. For further information please see the THINK! road safety website.
In order to monitor and check residents concerns the following procedure is followed for speed checks:
- Following a complaint, referral or if part of a scheme, an initial assessment is undertaken by an engineer to determine if, and the type of, survey required (24-hour / 7-day counter or off-peak 100 vehicle spot check)
- Request is passed to survey team to arrange for traffic survey to be undertaken
- Results are analysed and appropriate action taken, police advised if excess speed to undertake enforcement, consideration given to additional measures such as lining, signing or a traffic calming scheme
- Complainant advised of course of action proposed
- Results filed and arrangement made for appropriate measures to be undertaken
- Following introduction of scheme (usually six months after initial assessment) follow up survey arranged
- Results compared to determine if measures have been effective
