A new £29 million project to create England's first green transport city has invited bids from urban areas facing the worst congestion.
Nine cities across the country have been identified as eligible to bid for the funding over three years to encourage walking, cycling and public transport.
Transport minister Paul Clark said in a Commons statement that the project aimed to create at least one "sustainable travel city".
He said: "The aims of the sustainable travel city or cities are to ease congestion, reduce carbon dioxide emissions and increase levels of physical activity in the local area."
The cities identified as eligible for bidding are: Greater Manchester, West Midlands, West Yorkshire, South Yorkshire, Tyne and Wear, Merseyside, West of England (Bristol), Nottingham and Leicester.
