Where should bus stops go ...

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.
