Which type of information is NOT typically included in pre-trip planning for travelers?

Pre-trip planning for travelers typically involves gathering information that helps individuals make decisions before embarking on their journey. This includes assessing current traffic conditions and potential delays, which can be facilitated by variable message signs that offer real-time updates, kiosks that provide localized travel information, and telephone call-in services that allow travelers to get pertinent updates from a simple phone call.

In-vehicle navigation, while it may appear to support pre-trip planning, primarily functions during the trip itself. It provides guidance and directions while traveling but does not inherently serve as a tool for pre-trip decision-making. Instead, it tends to operate on information that has already been determined, making it less relevant to the initial planning phase where routes and travel times are being assessed. Therefore, when considering information that is utilized to strategically plan travel before departure, in-vehicle navigation is not typically included.
