Complementary instruments

HOV programs support and are supported by other public transport improvements and car share encouragement efforts, including parking control, park-and-ride, and marketing. In Bristol, UK, the local authority has stressed the importance of complementary policies; the authority has launched a car sharing website and provided free park and ride facilities to help drivers transfer between vehicles.

The failure of schemes in the US and mainland Europe has been linked to inadequate consultation with stakeholders and dissemination of the potential benefits of the scheme to the public and the media, indicating the importance of parallel implementation of these complementary measures.
