Developers have revealed what the proposed eco-town near Weston-on-the-Green would look like.
And ideas for the new community include a toll for people leaving the development by car.
After months of speculation and protest about the environmental impact of the new 15,000-home settlement, the company behind the scheme unveiled a draft masterplan of Weston Otmoor.
Developers Parkridge said there would be only a single point of access into and out of the eco-town, with a toll gate. The fee would fluctuate over the day, rising at times when surrounding roads were heavily congested.
The publication of the plan was quickly followed by the resignation of local councillor Neil Godwin, on whose farmland part of the eco-town would be built.
Mr Godwin faced calls to stand down as the village representative on Cherwell District Council because of a conflict of interest.
Mr Godwin, of Manor Farm, Weston-on-the-Green, said: "Quite a lot of local people were looking for me to resign a few weeks ago - and I said if I could not do my job then I would.
"Most parish councils wanted questions answering about the eco-town, but I couldn't answer them because of my conflict of interest."
Residents of Weston Otmoor are promised a fast and free tram service to carry people around the 800-acre site, with every home expected to be within 300m of a tram stop.
According to the blueprint, a new railway station, serving Oxford, Milton Keynes and London, would be built the south side of the site, with 10 trains per hour an hour to Oxford and six to Bicester.
A 6,000-space park-and-ride would be built next to it.
The developers say the town would require the current A34/M40 junction, one of the worst traffic bottlenecks in the county, to be entirely rebuilt.
The plan proposes that up to half the 15,000 homes would be affordable. Weston Otmoor would have a population of about 35,000, with 12,000 people working there.
The scale of the project is reflected in the fact that the plan includes eight primary schools and two secondary schools. The town would be dominated by a high street running through its centre with shops, schools and leisure facilities.
People now have until July 31 to have their say on the draft masterplan, with the Government set to produce a shortlist of up to 10 eco-town sites in October.
Seventeen roadshows, beginning on Sunday at Weston-on-the-Green Village Hall, are scheduled.
