Well travelled road effect

The familiar route felt faster. The clock disagreed.

The tendency to underestimate the duration taken to traverse oft‑travelled routes and overestimate the duration taken to traverse less familiar routes.

What it means and how it works

The effect stems from a combination of heuristic processing and attentional allocation: familiarity triggers a ‘routine’ mode that relies on stored schemas and reduces moment‑to‑moment monitoring of elapsed time, while novelty engages deliberate, effortful processing that amplifies the salience of time‑related stimuli, biasing duration judgments in opposite directions.

When a route is traveled repeatedly, individuals develop a sense of familiarity that leads to automatic, less attentive processing of the journey. This reduces the encoding of temporal cues, causing the remembered or anticipated duration to feel shorter than it actually is. Conversely, unfamiliar routes require more conscious navigation and attention, which inflates the perceived time needed, even when objective distances and traffic conditions are similar.

Why it matters

Misjudging travel times can lead to chronic lateness, inefficient scheduling, increased stress, and risky behaviours such as speeding to compensate for perceived time shortages. Understanding the bias helps individuals and organizations improve time‑management practices, transportation planning, and safety interventions.

The verified research on this pattern supports the following:

• People systematically underestimate travel duration on routes they travel frequently and overestimate it on routes they travel infrequently.

Common misunderstandings

Misunderstanding 1: The bias only affects driving; it does not apply to walking, cycling, or public transit.

Misunderstanding 2: The misestimation reflects actual differences in traffic congestion rather than perceptual distortion.

Misunderstanding 3: People are aware of the bias and can easily correct it without external aids.
