As often in the developing world, a type of Bus Rapid Transit is a key early move, with rail further in the future. The Arc's planners understand the need for a "Quick Impact" project that will show a transport benefit fast, and an intercity form of Bus Rapid Transit linking the West Bank's major centers makes sense if that's the objective. Compared to the transport options today, even a compromised BRT would be a striking improvement.
Doug recently updated me on this via email:
[W]e’re trying to keep awareness of the project high in hopes that the Obama administration’s negotiating team will see fit to incorporate the Arc into its diplomatic strategy ... . The 8-minute video is a quick refresher. You may be particularly interested in the short- to medium-term transit projects we have proposed: http://friendsofthearc.org/
Five years ago, proposing swift regional inter-city rail with connecting BRT service at each major Palestinian city – combined with medium density development along the BRT lines - may have seemed somewhat foreign for the region, but as you know in the interim Istanbul has opened 2 BRT lines, Amman is moving ahead pretty quickly with its own BRT system and impressive master plan, and Dubai opened its Metro with plenty of bus connections. Maybe transit and design can, after all, be part of the peace equation!
In some form it will have to be, so it's smart to be thinking about it now.
