Lewis Johnson, information analyst in the parking services division at Westminster, spoke to Computerworld UK last month and .

He said: "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."

"Early indications suggest that some of them are starting to see a decrease in the amount of time our officers are in there having to manage the spaces, but we aren't going to know 100 percent for a few weeks."

So how could this information impact parking policies in the area? There are a number of options. Johnson said that tariffs could be increased in streets where there is a high turnover of vehicles and demand is high, whilst tariffs could be lowered in quiet streets - all to try and change driving behaviour.

Johnson also said: "Or if a resident's bay isn't heavily used during the day, we could open that up. During the night and early morning it could be residents only, but during the day it could be used for loading, visitors, paid for parking etc. This information gives us the ability to look at these things."
