Explain the concept of intervening opportunities in urban travel behavior.

• A. Alternative destinations along a travel path reduce attractiveness of farther destinations; people settle for closer opportunities when they exist.
• B. Travel is always to the farthest destination.
• C. Intervening opportunities only matter in rural areas.
• D. They refer to opportunities for social events.

Answer: (A)

Intervening opportunities describe how closer opportunities encountered along a travel path can satisfy a traveler's needs, making farther destinations less attractive. In urban travel behavior, this means that if a nearer job, store, or service can meet someone’s needs, they’re likely to settle for that closer option rather than continue on to a more distant place. The presence of these closer options intercepts the journey, reducing the likelihood of traveling farther and shaping more localized, stepwise travel patterns within cities.

This idea refines how we think about travel choices: distance matters, but not in isolation. The closer opportunities along the route compete with distant targets, so the distribution of opportunities across space helps explain why people often choose nearby destinations even when farther ones exist. The other statements don’t fit because they imply travel to the farthest place every time, restrict the concept to rural areas, or misinterpret opportunities as social events rather than general substitutes that intervene in the travel decision.
