Route recommendation method and system

Abstract

The invention discloses a method and system for route recommendation. The method includes the steps that input of a departure point and a terminal point is received; the largest allowable mileage between the departure point and the terminal point, all first flight information with the departure point serving as a start point and all second flight information for reaching the terminal point without stops are acquired from a database, and places I capable of serving as transfer points are screened out; for each place I, the shortest distance LDI and the shortest distance LIA between the departure point and the place I and between the place I and the terminal point on the spherical surface are calculated respectively; whether the inequation LDI+LIA > the largest allowable mileage is satisfied or not is judged, if not, whether the latitude of each place I and the latitude of the departure point are the same or not is judged, if not, the distance LIi between the place I and a projection point of the place I on the latitude of the departure point is calculated, and if yes, LIi is set to be zero; according to the departure point, the corresponding place I and the projection point, the included angle a between a vector DI and a vector DA is calculated; when it is judged that a is not larger than a set value, flight information of a route formed by the departure point, the corresponding place I and the terminal point is displayed. By the adoption of the method and system, labor is saved and multiple routes are automatically screened out.

Description

technical field [0001] The invention relates to a route recommendation method and a route recommendation system, in particular to a route recommendation method and a route recommendation system that can automatically match a route required by a user without manual configuration. Background technique [0002] At present, when users inquire about flights between two locations on terminal devices such as computers and mobile phones, the flight information they inquire is not complete. This is because the displayed flight information is pre-configured manually. Users want to know When the flight information from a certain place to another place, only the pre-configured route can be viewed, and it is impossible to know whether there are other flight information to reach the other place besides the displayed flight information. For example, by manually pre-configuring the route from Beijing to Hong Kong, the configured routes are only Beijing-Nanjing-Hong Kong and Beijing-Shanghai...
