KurzweilAI: Traffic intersections of the future will control autonomous vehicles : "Intersections of the future won’t need stop lights or stop signs. They’ll look like a somewhat chaotic flow of driverless, autonomous cars slipping past one another as they are managed by a virtual traffic controller, says computer scientist Peter Stone, a professor of computer science at The University of Texas at Austin." [Interesting, but I disbelieve this is the likely technology path, there are 1 million signalized intersections and lord knows how many stop signs in the US, autonomous vehicles will develop protocols with each other before most jurisdictions fix their pathetically antiquated traffic signal controllers.]

Joe Verdoorn @ Newgeography Unintended Consequences of the Neo-Traditional City Planning Model: "This tactical criteria of the Neo-traditional model, however, can create unintended negative consequences. The criteria to which I refer includes:

  • grid street patterns
  • connectivity to adjacent neighborhoods
  • mixed, non-residential land uses
  • alley access/rear loaded house
The inflexible application of these tactical criteria enhances opportunities for criminal activities to occur."

Bradley Heard @ GGW Ride The Tide of light rail, Virginia Beach - Greater Greater Washington: "Dubbed "The Tide," South Hampton Roads' light rail system made its debut in Norfolk on August 19, 2011. The initial $338 million segment, operated by the regional transit agency, Hampton Roads Transit (HRT), is 7.4-miles, has 11 stops, and is currently located only within Norfolk's city limits.
...

Initial weekday ridership during the first year was projected to be only 2,900. However, the 6-month data shows that those early projections have been blown away. About 4,642 people ride The Tide during an average weekday. An even higher number—4,850—use the system on Saturdays, with 2,099 usually riding on Sundays."
