There was a proposal for Manchester in introduce a congestion charge zone motorists pay to drive in and out of the city at peak times. The BBC North West Tonight program wanted people's reaction to the proposed Greater Manchester congestion charge, from within the city but also people who drive in from outside the region. As these people don't get a vote but may end up paying the charge (subsequently the people of Manchester said no).
People were asked the following question “If a congestion charge is introduced in Greater Manchester, along with significant investment in public transport, will you:” and then asked to select one of the following options: drive and pay the charge, drive at different times, use public transport/motorbike/bicycle, work or shop elsewhere, or I am not affected by these changes.
The survey began on 14th October 2008. By the 10th December 2008, there were 14933 responses with 46.8% saying they would work or shop elsewhere. This online collaboration provided a unique picture of how well the proposal was going down across the north west of England as the map is updated every day.
