1. A transport navigation system, which, upon input information including information on a starting point and information on destination being input, searches, on the basis of the input information, for a travel route that is a route to travel from the starting point to the destination by a transportation means including a train, and which outputs travel route information relating to the travel route that has been obtained, the transport navigation system comprising:
the input information;
an actual timetable, according to which the transportation means has actually operated; and
a statistical information computing unit, wherein
the statistical information computing unit is configured, by using the actual timetable and the input information, to calculate a travel route from the starting point to the destination and a statistical amount about a travel time according to the travel route, and generate the travel route information using the travel route and the statistical amount;
the statistical information computing unit is configured, when calculating, by using the actual timetable and the input information, a travel route from the starting point to the destination and a statistical amount about a travel time according to the travel route,
by comparing actual timetable up to a day before a current day of operation and an actual timetable on the current day of operation, to specify past operation history in which departure time error from a current day of operation is a predetermined threshold value or below and to calculate the travel route and the statistical amount based on the specified history.
 
7. A transport navigation system, which, upon input information including information on a starting point and information on destination being input, searches, on the basis of the input information, for a travel route that is a route to travel from the starting point to the destination by a transportation means including a train, and which outputs travel route information relating to the travel route that has been obtained, the transport navigation system comprising:
the input information;
an actual timetable, according to which the transportation means has actually operated; and
a statistical information computing unit, wherein
the statistical information computing unit is configured, by using the actual timetable and the input information, to calculate a travel route from the starting point to the destination and a statistical amount about a travel time according to the travel route, and generate the travel route information using the travel route and the statistical amount, wherein the statistical information computing unit is configured to generate sample information by using the actual timetable and calculate the travel route and the statistical amount by using the sample information.
 
8. A transport navigation system, which, upon input information including information on a starting point and information on destination being input, searches, on the basis of the input information, for a travel route that is a route to travel from the starting point to the destination by a transportation means including a train, and which outputs travel route information relating to the travel route that has been obtained, the transport navigation system comprising:
the input information;
an actual timetable, according to which the transportation means has actually operated; and
a statistical information computing unit, wherein
the statistical information computing unit is configured, by using the actual timetable and the input information, to calculate a travel route from the starting point to the destination and a statistical amount about a travel time according to the travel route, and generate the travel route information using the travel route and the statistical amount,
wherein
the statistical information computing unit is configured to,
by using the actual timetable, calculate a similarity between operation of the transportation means up to the current time and each actual timetable, and
by using the input information, the actual timetable, and the similarity, calculate the travel route and the statistical amount.
 
9. A transport navigation system, which, upon input information including information on a starting point and information on destination being input, searches, on the basis of the input information, for a travel route that is a route to travel from the starting point to the destination by a transportation means including a train, and which outputs travel route information relating to the travel route that has been obtained, the transport navigation system comprising:
the input information;
an actual timetable, according to which the transportation means has actually operated; and
a statistical information computing unit, wherein
the statistical information computing unit is configured, by using the actual timetable and the input information, to calculate a travel route from the starting point to the destination and a statistical amount about a travel time according to the travel route, and generate the travel route information using the travel route and the statistical amount,
wherein the statistical information computing unit is configured to, when calculating, by using the actual timetable and the input information, a travel route from the starting point to the destination and a statistical amount about a travel time according to the travel route, classify the travel route into one or more groups on the basis of similarity relating to departure time or arrival time, and create travel route information corresponding to the travel route of each of the group into which the classification has been performed.
 
10. A transport navigation system, which, upon input information including information on a starting point and information on destination being input, searches, on the basis of the input information, for a travel route that is a route to travel from the starting point to the destination by a transportation means including a train, and which outputs travel route information relating to the travel route that has been obtained, the transport navigation system comprising:
the input information;
an actual timetable, according to which the transportation means has actually operated; and
a statistical information computing unit, wherein
the statistical information computing unit is configured, by using the actual timetable and the input information, to calculate a travel route from the starting point to the destination and a statistical amount about a travel time according to the travel route, and generate the travel route information using the travel route and the statistical amount,
the statistical information computing unit is configured, when calculating, by using the actual timetable and the input information, a travel route from the starting point to the destination and a statistical amount about a travel time according to the travel route,
by comparing actual demand up to a day before a current day of operation and an actual demand of a current day of operation, to specify past operation history in which error of the number of passengers on the train from a current day of operation is a predetermined threshold value or below and to calculate the travel route and the statistical amount based on the specified history.
