How would this new transit system be different from the ARC fixed-guideway system that was bandied about for much of the last decade? As I recall, various iterations of that included stops at ARTIC, the Platinum Triangle, the future Pumbaa garage, and Convention Center. Why was that project cancelled after so many years, and what makes them think that this latest version will be any different?
I was in closed-door meetings for related projects with City and OCTA staff (along with representatives of other local/regional transit agencies) circa 2011, and everybody at the time acted like the project was a sure thing, despite not knowing basics like the type of vehicle/system or whether it would be mixed in with street traffic. They were working on an accelerated schedule in order to qualify for stimulus funding as a shovel-ready project, but that ship has long since sailed.
The fixed-guideway system seemed to be in serious talks from the late 00's, until just a few years ago. I think it finally faded away around the same time the "eastern gateway" phase was coined and those plans began to be developed beyond the conceptual level. The number of times the original project was modified, delayed, and restarted gives me serious doubts that we'll ever see anything come from the latest proposal.
A trackless streetcar is a bus.
This. Whether it's dedicated right-of-way, electric, driverless, disguised to look like an old-timey trolley, use placemaking at the stops, or have any number of other whizzbang features, it sounds like this latest proposal will ultimately be a bus system. That's not a bad thing, but we need to call a spade a spade.
There are some obvious advantages to using various bus systems like the low start-up cost, low maintenance cost, lack of specialized operations training, easy to scale service up/down, and ability to reroute around disabled vehicles. The disadvantages are primarily superficial, since a bus doesn't seem as sleek and sexy, approachable, or reliable as a dedicated fixed-guideway system, but that's all easily overcome with the proper window dressings, especially on a point-to-point tourist-oriented shuttle like this.
