System for planning and revising an itinerary based on intended travel time and expected consumption time
First Claim
1. An itinerary preparing system for preparing a travel plan based on input information, comprising:
- input means for entering travel plan information which includes an intended travel time taken from start to end of a trip;
acquiring means for obtaining an expected consumption time of the trip in accordance with said travel plan information;
excess/shortage determining means for comparing said intended travel time with said expected consumption time of the trip to determine an excess or shortage of said expected consumption time relative to said intended travel time; and
plan changing means for revising the itinerary, when said excess/shortage determining means finds said excess or shortage, by changing said intended travel time so that the excess or shortage can be offset.

Abstract
An itinerary preparing system capable of easily preparing a complete travel plan that efficiently incorporates desired visiting places. A user inputs from a terminal an intended travel time of a trip together with visiting place information. Based on the visiting place information, a calculating section for calculating an expected consumption time in an information center calculates an expected consumption time for transportation to reach a visiting place or an expected length of stay thereat. An excess/shortage determining section compares the intended travel time with the total expected consumption time of the trip, and adjusts the intended travel time or the total consumption time based on the comparison result. Consequently, an itinerary preparing section makes a travel plan and transmits it to the terminal via an I/O section. When the received itinerary is approved at the terminal, the information center revises the itinerary by filling in free time of the itinerary. When the revised itinerary is sent back to the terminal and approved, a final itinerary is provided.

-
1) receiving travel plan information which includes an intended travel time taken from start to end of a trip; 2) obtaining an expected duration of the trip in accordance with the travel plan information; 3) comparing the intended travel time with the expected duration of the trip to determine an excess or shortage of the expected duration relative to the intended travel time; and 4) when the determining step finds said excess or shortage, changing the intended travel time so that the excess or shortage can be offset.
