Using data from studies of 16,716 vehicles at crosswalks equipped with amber beacons in seven states, including Illinois, researchers found on average 72 percent of drivers yielded to pedestrians. Interestingly, only 33 percent out of 1,402 vehicles yielded in Illinois.
Drivers tended to stop more frequently if the amber beacons were located overhead instead of alongside the road, near a school or transit stop, and on roads with fewer lanes, the study stated.
A different Federal Highway Administration report found a huge gap in drivers obeying amber beacons at crosswalks that ranged from 19 percent at one site in Illinois to 98 percent at a Colorado location…
Meanwhile, another type of crosswalk signal with a red light offers a promising track record. Known as a pedestrian hybrid beacon, the device typically hangs over an intersection and is dark until someone presses a button activating a yellow warning light, then a red beacon for drivers.
Studies of 3,504 drivers in Texas and Arizona showed 96 percent on average stopped.
All the road signs and traffic lights in the world will not lead to 100% compliance from drivers. Of course, some solutions are more effective than others. Later in the article, an expert explains:
“Traffic engineering is harder than drivers may think,” Fitzpatrick said.
Another problem that could be solved with self-driving cars. Until then, cyclists and pedestrians have to be really careful with cars driven by humans who can have all sorts of reactions to people crossing the road.
