How to realize the self-built travel assistant function of Baidu Travel and Backpacking Rabbit website?

The biggest difficulty in realizing this kind of travel assistant lies in the need for big data support. Let me give you an example.

A man set out from China to travel around the world.

He chose to go to Cape Town, South Africa on the first day and visit Table Mountain and other scenic spots around Cape Town on the second day. On the third day he thought of Cairo, Egypt; Go to Brasilia, Brazil on the fourth day. A closer look at such a trip is impossible, because there is a conflict between the travel time and the play time of the points.

The itinerary made by such a itinerary assistant is feasible, and it must be able to calculate the transportation time cost from each departure point to the new destination (the transportation of any two places in the website must be calculated). Due to the different modes of transportation, it takes different time, and each destination needs to correspond to all other destinations, so it needs a lot of data. A few days ago, the customer asked us to be such a travel assistant for him, and now he is having a headache with the data ... It is not difficult to solve the problem with our own CMS system, but the data needs to be manually sorted, uploaded and updated, and the more places we do, the more data we have.
