Pappas reviews a wide range of research related to road traffic safety. Design related information presented includes “Visually cluttered roads, confusing signage, and broad thoroughfares that practically beg drivers to stomp on the accelerator can encourage behaviors that raise risk. . . . Design choices like medians, trees, and cycle lanes can obstruct drivers’ views of the horizon and move their focus close to the front of their cars, encouraging more cautious driving.”
