A £4.5bn package of congestion-fighting plans which could affect Huddersfield was being unveiled today.
A collection of ideas was being revealed at the launch of the Leeds City Region Development Plan in Halifax.
They include tram trains, further electrification of local rail routes, new and upgraded road links and rapid bus transit incorporating the latest technology.
Other ideas are bus and rail-based park and ride schemes, new transport interchanges and an extension of the money-saving MetroCard to cover the whole region.
The plans are set out in a 25-year 'transport vision'.
The transport plans were being presented to an invited audience of politicians and members of the business community.
Metro director general Kieran Preston was saying how the city region's growth and prosperity could be hit if under-investment in transport continued.
Politicians and business leaders want the gap in Government spending on transport - which is now £200 per person in the Leeds City Region, as against £600 in London - to be closed.
Mr Preston added: "We are not asking for parity with London.
"If the Government just halves the gap we can deliver the vital networks that will join up housing and employment, people and jobs and help the Leeds City Region to thrive."
He said that "£4½bn for transport schemes seems like a big ask.
"But when you consider that in economic, social, health and environmental terms they repay that cost three times over it makes absolute sense.
"The question we shall be putting to ministers and civil servants when we present this vision at the Commons this months is not: 'Can you afford to make this happen?' but: 'How can you afford not to?' "
