The City of Milwaukee painted the pavement marking to identify where to place your bicycle if you want to induce the traffic signal to change heading east on Pittsburgh at S 1st Street. This pavement marking goes along with the sign posted on the utility pole. That phase of the traffic signal is one of the few in the City of Milwaukee that is not on recall, or a timed cycle. That means the light will never turn green until there is a vehicle waiting there that induces a current in the inductive loops saw cut into the pavement. Last year I went out to the intersection and a City traffic signal technician tuned the loops to detect a bicycle. The trick is you have to put your wheels in the right spot. The new bicycle and two lines mark the saw cut where you stop your bike.
Wisconsin traffic laws now allow operators of bicycles and motorcycles to advance through an intersection when facing a red light if they believe the signal will not detect them. This is a case in which a law was written by legislators who did not consult a traffic engineer. There are many signalized intersections in the state that are on 90 second cycles, so proceeding through a red after 45 seconds makes no sense beyond the fact that people tend to be impatient. There are even some intersections on 120 second cycles. Either way, the law is the law, and here is the exact language of the rule, follow the link below for the full statute with all references:346.37(1)(c)4. 4. Notwithstanding subd. 1., a motorcycle, moped, motor bicycle, or bicycle facing a red signal at an intersection may, after stopping as required under subd. 1. for not less than 45 seconds, proceed cautiously through the intersection before the signal turns green if no other vehicles are present at the intersection to actuate the signal and the operator of the motorcycle, moped, motor bicycle, or bicycle reasonably believes the signal is vehicle actuated. The operator of a motorcycle, moped, motor bicycle, or bicycle proceeding through a red signal under this subdivision shall yield the right-of-way to any vehicular traffic, pedestrian, bicyclist, or rider of an electric personal assistive mobility device proceeding through a green signal at the intersection or lawfully within a crosswalk or using the intersection. This subdivision does not affect any authorization for a bicyclist under subd. 2.
This is the first location we have used this symbol and sign. Are you aware of another signalized intersection in the City that needs it?
