How often do you think about stoplights? Not just to acknowledge that the light is green or red or how many times the “Don’t Walk” hand on the pedestrian crosswalk counter has flashed so you know how long you have to cross, but the design and placement of that signal. (The red hand flashes 17 times at the freeway exit intersection on the Lowry Hill Greenway on Lyndale Avenue, for reference.) I will grant, the readership of this fine blog is more likely to have thought about this than most.
I have had a growing irritation with placement of signals over the past few years, particularly after my most recent trip to visit a former host family in Austria, where I lived off and on for almost three years. Like many others who have commented on differences between European and American street design, I was struck by how much safer I feel as a pedestrian there. A part of that was because the crosswalk was significantly less blocked than the average U.S. intersection. That could relate to cultural norms, more driving training (getting a license in Austria is both time consuming and expensive) or a stronger restriction on right turns on red (generally not allowed anywhere), but another aspect was simply where signals are placed at intersections. Most often, they are on the near side of the intersection. If there is a signal in the middle or on the far side of the intersection, it is supplemental, not primary.
What does that mean for user safety? Vehicles see the light sooner before reaching the intersection, which makes it less likely that cars run red lights. Importantly, though, vehicles need to stop farther back to see the signal, meaning that the crosswalk is kept clear for pedestrian use. In Austria and Switzerland, a stop bar serves as an extra indicator of where cars should stay, but the signal placement itself is doing most of the work. This intentional design choice makes it safer for multiple road users to interact in the same space. Pedestrians have less fear of cars inching forward and encroaching on the crosswalk, and cars are less likely to run red lights because they can see the signal sooner. Keeping cars farther back also allows for a tighter turning radius for a vehicle coming from a perpendicular road, allowing intersections to be smaller, use fewer materials and have shorter crossing distances for pedestrians.
