Here is another episode of Perils for Pedestrians. This one talks about what is happening in Washington DC including the on again off again Purple Light Rail Line.
There is also a discussion with a representative from a county planning organization that covers the county that includes Charleston, South Carolina. One of the problems we face here in Salt Lake City is the lack of a metropolitan planning organization that provides more cohesive planning than the wide range of city planning agencies we currently have. While we do have the Wasatch Front Regional Council, it is not a primary planning organization for the area.
Finally there is an interview with a traffic engineer that gives some explanation on how pedestrian signals are timed and some of the terms used.
