Benefit Summary HTML

The study primarily intended to evaluate the operational and safety impacts of pedestrian hybrid beacons (PHBs) on Arizona state highways (higher-speed roads) to understand their impacts on vehicles and pedestrians. The study investigated the relationship between crashes at PHB locations and two variables: 1) the spacing from nearby signalized intersections, and 2) other roadway characteristics. PHB indications are as follows: dark, flashing yellow, steady yellow, steady red, and alternating flashing red. A total of 10 sites (all with speed limits of 45 or 50 mi/h) with 822 PHB locations were evaluated. Sites were located throughout Arizona in Bullhead City, Scottsdale, Phoenix, Tempe, Gilbert, Tucson, Sierra Vista, and Pima County. An operational analysis assessed PHB effectiveness on higher-speed streets with an observation study. A total of 1,214 pedestrians and bicyclists were observed between April 25 and May 8, 2018; 40 hours of video data of each site were manually evaluated. A safety evaluation assessed a total of 343 sites (186 PHBs, 56 signalized intersections, and 101 unsignalized intersections).

Lesson Background HTML

The study primarily intended to evaluate the operational and safety impacts of pedestrian hybrid beacons (PHBs) on Arizona state highways to understand their impacts on vehicles and pedestrians. The study investigated the relationship between crashes at PHB locations and the spacing from nearby signalized intersections, as well as other roadway characteristics.

PHB indications sequence through dark, flashing yellow, steady yellow, steady red, alternating flashing red and then dark again. A total of 822 PHB locations across 10 sites (all with speed limits of 45 or 50 mi/h) were evaluated. The sites were located throughout Arizona in Bullhead City, Scottsdale, Phoenix, Tempe, Gilbert, Tucson, Sierra Vista, and Pima County.

  • An operational analysis assessed PHB effectiveness with an observation study. A total of 1,214 pedestrians and bicyclists were observed between April 25 and May 8, 2018; 40 hours of video data of each site were manually evaluated.
  • A separate safety evaluation assessed a total of 343 sites (186 PHBs, 56 signalized intersections, and 101 unsignalized intersections).
