The study, carried out on behalf of TRICS, the transport and development planning industry tool, found that the amount and composition of parking can undermine any benefits that could otherwise have been achieved through including different types of land use on a site.
Locations with four or more developments reduce the total number of external trips by around 20 per cent through trip linking, the research found.
But it also showed that these benefits are lost for comparable sites with a generous supply of parking.
Colin Black, divisional director for transport planning in London at JMP, said that parking management should be better integrated into travel plans for development sites.
