Another problem at traffic-actuated lights in MA is described on this page: http://www.bikexprt.com/massfacil/no...rd/ongreen.htm. Have you ever seen the sign that says "bicycle stop on line for green"? First of all, it is poorly worded (sounds like it's asking us to stop on the line when the light is green--why would we do that?), and second, the "line" referred to often doesn't even exist on the roadway!! The idea was to have a pavement marking painted over a part of the loop that would allow a bicycle to trigger the light, but where I have seen these signs there was no such marking, and according to the page referenced above, this problem is widespread (the page gives examples mostly from the Boston area; I have seen it in Millbury and Grafton). An example of a good idea but lousy execution.
