A notorious accident blackspot in Bradford has been tamed.

There have been no deaths or serious injuries on Thornton Road since safety measures were introduced last May.

Collisions have been halved in a year and casualties have fallen from 45 to 12, the West Yorkshire Casualty reduction Partnership said today.

The success is due to £140,000-plus measures including a 30mph limit, two mini-roundabouts, pedestrian crossings, cycle lanes, safety zones and four speed cameras.

And the cameras have not even been switched on yet - though they will be this month.

Before the alterations, Thornton Road had claimed six lives in three years. It had left 25 victims suffering from serious injuries.

But in the last 12 months there were only ten crashes along the road, compared to 24 the year before. And casualties fell from 45 to 12.

The one serious injury in the last year was before the speed limit was cut and the cameras introduced.

"These are remarkable figures that show just what can be achieved when drivers are encouraged to slow down," said Steve Thornton, a principal traffic engineer with Bradford Council. He is also chairman of the west Yorkshire Casualty reduction Partnership, which installs and operates safety cameras, and the west Yorkshire Road Safety Strategy Group.

He continued: "The benefits to the community are enormous. Pedestrians can cross the road more easily, while students and staff at Thornton Grammar School have warmly welcomed the safety improvements.

"The engineering scheme, which includes two mini-roundabouts, pedestrian crossings, cycle lanes and safety zones, has also made a major contribution to cutting collisions and casualties."

Thornton Grammar had campaigned vociferously before the measures were approved early last year and had made representations to Prime Minister Tony Blair.

Deputy head Elaine Dawson had said at the time: "We have been campaigning for 18 months and in the last two years two of our children have been knocked down."
