signalize

Caltrans officials hope to be able to fully open the northbound lane near Rocky Creek Bridge as soon as possible, with signalized, one-lane traffic.

To test its effectiveness, researchers collected data over the course of three weeks in March 2022 from each of Birmingham's 34 signalized intersections -- most of which are fixed-time systems.

The researchers described Broad Street, a five-lane arterial road, as "a daunting road to cross with or without a signal in Hilltop, and distances to signalized crossing areas can be several blocks."

A federal judge there appointed an independent monitor and in December 2021 gave officials a decade to gradually make at least 10,000 of its approximately 13,000 signalized intersections accessible to blind pedestrians.

Tracking how frequently red-light turns factor into pedestrian or bicyclist injuries is difficult because they are often coded as “failure to yield,” which encompasses more than just signalized intersections.
