In a nice article in The Oregonian about my friend Robert Bertini’s Portland State University lab: Lab helps TriMet glide to more green lights , simulation tests comparing bus stop locations on the near and far side of intersections shows bus stops should go on the far side of intersections, reducing bus delay. This is a valuable use of simulation, that should be corroborated with empirical evidence (though I am fairly sure it is right). I suspect in general it also reduces the delay of other vehicles. Another question is how does it affect access times to bus stops, which depends on local land use issues.
Briefly noted, Randy Crane has a nice Post on traffic in Los Angeles. Fortunately, we don’t have congestion here in the Twin Cities
