Road test for self-braking car that obeys speed limit

A device that detects the speed limit and automatically applies the brakes to your car to prevent speeding will begin trials this month in Leeds.
Preliminary tests show that the system, known as Intelligent Speed Adaptation (ISA), could save the lives of more than a thousand people killed by speeding drivers each year.
The Government has allocated ¡2 million for four consecutive six-month trials on adapted Skoda Fabias and is considering ordering manufacturers to fit the device on all new cars within a decade.
Unlike the crude speed limiters fitted to lorries and coaches, the new device matches the driver's speed to the limit that applies on each road.
Each of the Skodas has a computer under the floor that carries a digital road map showing the limits on all roads in Leeds as well as on motorways and trunk roads in the rest of Britain. The computer uses a satellite positioning system to detect the car's location. A digital display informs the driver of the speed limit.
If a driver is approaching a village with a 30mph limit, the system will send a message saying that the limit is changing.
It will also detect whether the driver is responding and, if not, the device will begin to apply the brakes 300 yards before the 30mph sign. The accelerator pedal will not respond to normal pressure once the car has reached the speed limit.Drivers will be able to override the system in an emergency. It can be disengaged either by pressing a red button on the steering wheel or by pressing down very hard on the accelerator.
Oliver Carsten, the project leader and Professor of Transport Studies at Leeds University, said: We want to assess whether the system changes people's driving habits. Once the system is switched off, they might feel so liberated that they drive like a bat out of hell. Alternatively, they might be more aware of speed limits and be better drivers.
Professor Carsten said initial tests had shown a positive reaction from motorists, who felt safer with the system and had fewer near misses with cyclists and pedestrians.
People speed because they can and because others do. As with drink-driving many years ago, people think it is OK because it is the norm.
About 65 per cent of drivers break the speed limit in urban areas, according to the Transport Department, and more than half on motorways.
The Government hopes that the results of the trials will show such a substantial benefit that manufacturers will agree to install the device voluntarily. Ministers will reserve the right to impose the system on the industry. The Commons Transport Select Committee has called for all new vehicles to have the device from 2013.
Richard Brunstrom, the Chief Constable of North Wales, supports the introduction of speed-limiting devices.
We are concerned that there continue to be on sale in Europe vehicles designed to be capable of travelling at more than twice the legal limit.
