The Psychology Behind Speed Control Measures

The visual and psychological effects of speed humps and bumps play a crucial role in traffic control. When a driver sees the bumps in the road, it is a reminder for them to slow down and obey the speed limit. The presence of these physical features triggers a cognitive response that encourages safer driving behaviors. This response is part of a ‘driving’ heuristic, a type of cognitive shortcut that allows drivers to perform tasks such as slowing down more or less automatically, without the need for conscious deliberation. Drivers, including those with ADHD, often rely on heuristics to manage the constant influx of information and to perform driving tasks efficiently. Speed humps and bumps serve as cues that fit into these heuristic routines, prompting drivers to adjust their speed without exhaustive attention. This is particularly important for individuals predisposed to quick decisions and rapid cognitive processing, as it helps them navigate the roads safely without becoming overwhelmed by stimuli.
The bumps are small, but they are large enough to be noticeable and effective in signaling the need for caution.
The strategic use of speed control measures can harness these psychological tendencies to enhance road safety. By integrating speed humps and bumps into the driving environment, traffic planners can create a self-enforcing system where drivers instinctively know to reduce speed, thereby reducing the likelihood of accidents.
