Savile Row was occupied 85 percent of the time, whilst Sackville had 45 percent occupancy - but there are equal amount of parking spaces and are a very short distance apart.

The Council is using both the app to feed information to users in real-time, but also marshals on the street, who receive the same data, advising drivers where they should go.

Johnson said: "We wanted to see if we could change the parking behaviour through a smartphone application and marshals. We are telling them in real-time that Sackville Street is empty - just take that two extra minutes to drive around the corner and you will find availability."

The trial has now been extended to three other locations in the borough, which covers 200 spaces in total that have infra-red sensor technology that identifies whether or not a car is parked there. This is then delivered to the back-end database in real-time so that Johnson and Lodge can visualise what the occupancy rate is.

"The app has been out about three weeks and we have had over 1,000 downloads. We have started to do an analysis of the data we have from the sensors to see how many vehicles we have had through the area, how long they have stayed, and we are just putting together the applications to take in feeds," said Johnson.
