TfL have made available (through their ‘Romulus‘ site) two studies of the number of parking spaces in London, the first carried out in 1999 and the second in 2004/05. You can find them by expanding the ‘Reports’ section of the left-hand menu, but be warned, they’re both big files (56mb in the case of the first one!).
The most interesting bit is probably the impact of the congestion charge on parking availability in Central London, as reported in the second study:
- In central London there was a reduction of 45% in the number of parking spaces for employees at workplaces, compared with 1999/2000. With the introduction of congestion charging in 2003 there was less incentive for employees to drive to work in central London, and there were fewer small car parks available for employee parking.
- There was also a 10% reduction in spaces available to the general public in central London car parks. The overall reduction in central London car park spaces (excluding those in residential car parks) was 24%. By contrast there were increases in available car park spaces in inner and outer London, outside the central area. In inner London there was an increase of 23% and in outer London an increase of 30%.
- There was a reduction in on-street parking spaces other than at meters and pay-and-display areas. In central London there were 27% fewer spaces on single-yellow or single-red lines, which normally allow parking in the late evening and at night. In inner and outer London there were 9% fewer unrestricted on-street spaces.
