The Assembly's 20-year South East Plan aims to make better use of public transport and reduce car journeys. The Assembly commissioned both a study and workshops in Oxford, Portsmouth and Guildford on how to change travel behaviour.
The results will see the Assembly take a lead role supporting local authorities to help deliver smarter travel behaviour.
They will prepare guidance documents to help local authorities work towards integrated transport systems that encourage less car use, and developing a framework for rail station travel plans, making it easier to access stations and link to other forms of transport, such as buses or park and ride sites.
The assembly will also coordinate travel information and ticketing, perhaps introducing an Oyster-style card for the train, bus and parking. They also plan a resource centre which can monitor authorities, but can also be consulted by local authorities for good practice, research and contacts.
Cllr Keith Mitchell, Chairman of the Assembly said, "Travelling more wisely is what the future is about. Changing our behaviour is challenging so we need better access to better public transport encouraging communities to be more sustainable.
"We are already talking with key stakeholders including the region's local transport authorities to help deliver the action plan," he said.
The study and action plan will also be considered by the South East England Regional Transport Board at its meeting today.
