A pilot street parking scheme has been launched in Birmingham aimed at helping motorists find available spaces in part of the city.
Some 200 sensors have been embedded in selected roads in the Jewellery Quarter area that are designed to detect the presence of a parked vehicle.
The information will then be made available via a smartphone application or website to indicate free spaces.
The company behind the trial hope it will benefit businesses and drivers.
It is set to be extended to streets in the Colmore Business District area at a later date.
Eddie Fellows, from Amey, the city council's partner in maintaining and managing roads in Birmingham, said: "This trial will give us some indication of the ways in which these sensors can be used successfully, and what benefits they hold for Birmingham.
"Everyone has been in the position of finding themselves in an unfamiliar part of the city, not knowing where they might find a parking space and having to drive around in circles until they find one.
"It is our belief and desire that by using the data collected from the sensors, drivers can cut the time they spend and the fuel they use looking for a space, as they will know where there are pockets of availability."
Keith Stanley, operations director for the Jewellery Quarter Development Trust, said: "Driving around looking for a parking space can be very frustrating.
"We believe the parking bay sensor initiative will help to ease some of the stress that city centre parking can create."
