General Road and Highway Discussion

1) "But a roundabout is not always the best solution. At the moment there are 65 signalised intersections in the municipality of ʼs-Hertogenbosch."

Contrast this to the current absolute preference for roundabouts at the RoW even in places where it seems a controlled traffic intersection is better.

2) "What you perceive as a green wave is really a series of quickly getting green because you were detected and there was time in the cycle to give you green at just the right moment!"

This is just a green wave implemented through a distributed protocol, but a green wave nonetheless.

1) I don't know that we have an "absolute preference" for roundabouts here, there are numerous examples of regional staff considering roundabouts and then deciding on signalized intersections, Weber and Victoria and Weber and Wellington are examples I can think of off the top of my head.

2) That depends on who you ask, traffic engineers see a "green wave" as timing the lights specifically so that vehicles receive greens all the way along.  The point is, you don't need to do that in order to achieve the same effect for traffic, which removes many restrictions from lights.
