The first step is a backbone rail line that starts in Chapel Hill, runs up to Duke, then through Durham to RTP, to the Airport, and from there to and through Raleigh. Then add spurs and spokes to cover the region and funnel people to the backbone.
Good luck getting the legislature to authorize, much less fund that.
Moreover, the strongest / largest municipality in the region (Wake/Raleigh) seems to be the least interested in serious non-road public transport projects, as they just withdrew from their chunk of the light rail connection with Durham / CH.
The talent is here at UNC and Duke but airport and local public transit is the weakest point.
With that said, I'd love for them to come here as long as they maintain salary parity.
The population density is probably higher on average in New Jersey than in metro Raleigh..
As someone who lives in Durham and frequently commutes to Chapel Hill and Raleigh, the existing infrastructure would NOT support a big increase in commuters. During morning and afternoon rush hours, the highways are just BARELY large enough to prevent total gridlock. If you add just 10000 more cars commuting to Raleigh from Durham or Chapel Hill, you have a traffic nightmare in the making.
That said, I do think we're somewhat competitive for this, even though I don't want to see Amazon move in. The housing stock availability is a huge liability for the locals...we're already in a seller's market right now.
