It claims up to 30% of the traffic in city centres is accounted for by drivers searching for parking spaces. It has already supplied a system for Bristol City Council covering 3,000 spaces. Glasgow City Council has just signed a deal worth more than £200,000 for the system to cover four car parks and 4,000 spaces.
A spokesman for ATT, based in Dublin, said: 'This initiative will make a major contribution to the reduction of traffic problems in Glasgow. The new system will inform drivers in real-time of the number of available spaces to assist in the reduction of congestion.'
