When talking with someone who worked there about the streetcar idea, I was told this small football stadium, designed to seat 31,500, was actually seating around 50,000 to 60,000 people for this show. Imagine if almost a quarter of the city's population decided to go to this stadium around the same time! The numbers police, security, and event workers were likely provided at the start of the day were no where near what the final numbers became at the start of the show, as they
continued to sell tickets and add seating hours before the show. Was the facility even designed to move this many people through the gates and concourse? Learning this, I can see the problem. I was also told only one of the roads around this facility was designed to handle any real traffic and this facility is too far from the main limited-access highways (think Interstate-style highways). Considering both the coliseum and football field were designed to hold a combined 47,000 people, if they have enough parking to both be sold-out at the same time, that is still below the crowd levels seen at the event. If they have shared parking and never thought they needed enough parking for both facilities to be sold-out on the same day, then... wow!
If they want to host another show of this size or expand that football stadium in the future, they will have to look at the North-South Streetcar project first and design it for 10 minute headways. The person I spoke to said that if Wake Forest football grows enough to need a larger stadium, they can't expand that facility. It would have to be a new stadium in a location next to major highways.

And yes, out-of-towners taking the most familiar route or what appears to be the simplest route and not taking any recommended shortcuts will always be a problem.
That conversation was interesting enough to create its own thread for. I do feel Councilwoman Adams should use this nationally embarrassing incident to push harder for the North-South Streetcar Project between Wake Forest and WSSU.
