Theory: People on bikes are far more apt to comply with traffic controls - even at a time penalty - when they are explicitly intended for them. Think bike-specific signal faces.
Hunchy anecdata: Bike riders seem to wait for the short bike-exclusive community path crossing of Mass Ave at Cedar at even higher rate than peds wait for their earlier and longer-phase crossings. (I cede to @sofio wisdom here tho)
@bikepedantic Personally I'm less likely to comply with bike-specific signal faces, but that could be because the ones I use with any regularity are awful. The ones in Brookline Village are especially bad, and the ones on the Staniford/Causeway cycletrack are also bad. They feel like they were put there just to cause undue delay.
@aweechwhobikes yeah, def ones that are there because the reasonable alternative isn’t legal (Mass Ave/ Beech). Haven’t ridden these, but feel like I’ve heard mutterjngs about the Brookline ones before
