Park and ride schemes are very effective methods for changing a transport corridor and moving travellers to more sustainable forms of transport. They can take cars away and move passengers on to public transport. Where the car parking is well located, the public transport journey reasonably priced and the public transport frequency sufficient, park and rides can influence multiple corridors into a city by attracting journeys that were travelling towards a major destination.
They are also reasonably cost effective to set up using land outside of city centres, and require minimal fixed infrastructure. However, they can also receive substantial infrastructure to ensure that the bus receives a number of priority measures ensuring a reliable and punctual journey.
Park and ride is very effective but work should be taken to make them hubs that can be served by people walking and cycling to them as well. Tickets can be sold per vehicle arriving to prevent the perverse incentive where cars full of people bypass park and rides because parking in centres remains cheaper than tickets for a number of people on the park and ride.
Some councils use Park and Rides to develop a bus route on a corridor. This can support developments occurring on a transport corridor or minimise the requirement to provide alternative bus services. This could be due to the lack of housing on a route or a suitable destination.
If the alternative to park and ride is just as fast and parking costs comparable to the bus/train, then park and ride can be difficult. If the operation of the bus service fails to generate enough revenue from users, a high frequency service can be costly to the council to keep running.
