Well-traveled road effect
The Well-traveled road effect is a cognitive bias that causes people to underestimate the time it takes to travel routes they are familiar with. This phenomenon suggests that people perceive regularly traveled paths as shorter than they objectively are, due to an increase in perceived efficiency and ease of navigation.
How it works
This effect operates on the principle that when an individual frequently travels a particular route, their familiarity with the landmarks and the sequential nature of the path reduces the cognitive load and perceived time required for the journey. As one becomes habituated to a particular route, the brain processes the information quicker and more efficiently, causing the journey to seem shorter than less familiar paths of similar or even shorter lengths.
Examples
A classic example of the Well-traveled road effect occurs when a commuter travels from home to work. Despite the objective distance or travel time, the route feels shorter over time due to repeated exposure and established expectations of the journey. Conversely, a driver taking a novel route, even of similar distance, may perceive it as longer due to unfamiliarity and the additional cognitive effort required to navigate.
Consequences
This bias can lead to underestimating travel time and planning, potentially resulting in lateness or scheduling conflicts. In broader contexts, it might contribute to complacency in travel planning or decision-making, as individuals may not consider more efficient or effective routes simply because they are less traveled.
Counteracting
To counteract the Well-traveled road effect, individuals can deliberately plan routes using map services or time the journey between different routes to obtain objective travel times. Diversifying travel paths and remaining mindful of alternative routes can help maintain a more accurate perception of time and distance.
Critiques
Critics of the Well-traveled road effect suggest that its impact might be overstated and that other factors such as mood, weather conditions, and the mode of travel can significantly alter an individual's time perception beyond mere route familiarity.

Real-world examples showing how Well-traveled road effect manifests in practice
Context
MetroFreight is a regional last-mile delivery operator serving a dense metropolitan area. After rapid growth, operations managers leaned on experienced drivers' personal estimates when creating daily routes to maximize utilization.
Situation
Dispatchers built schedules based on veteran drivers' stated travel and service times for recurring urban routes. Because those same drivers run the same circuits daily, planning assumed predictable, compact trip times and narrow buffers between stops.
The Bias in Action
Managers and drivers both assumed familiar routes took less time than they actually did — estimates were based on habit and perceived ease rather than objective measurements. That perceived efficiency led planners to cut slack times and pack more stops into each route. When predictable but infrequent factors (construction, school dismissal traffic, parking searches) occurred, the schedules had no margin to absorb them. The team continued to accept drivers' optimistic commute-time estimates because they had always 'done it that way' without checking telematics.
Outcome
Over several weeks, routes began to slip: deliveries missed promised windows, customer complaints rose, and drivers worked longer shifts to finish manifests. The company scrambled to re-route mid-day and paid surge overtime to meet critical deadlines, increasing costs and harming customer trust.
