High-speed railways are always on the move, literally and figuratively. But how do they decide how much to charge for tickets? This is a big question for train companies who want to be both profitable and appealing to passengers. Let's break down how they can make smart pricing decisions.

First, we need to understand that not all passengers are the same. Some want speed, others comfort, and some just want a cheap ride. This is what we call differentiated demand. Each train has a different supply of seats and services too.

To figure out the best pricing strategy, we build a network that shows all the trains, their schedules, and how passengers might choose one over another. This includes looking at the total cost for passengers, which isn't just about the ticket price. It also considers how long the trip takes, how convenient it is, and how comfy the ride is.

Now, we want to do two things: make the most money for the company and make the trip as good as possible for passengers. This is where a smart pricing model comes in. It uses a fancy algorithm to find the best ticket prices that balance these two goals.

In China's Shandong province, they tested this smart pricing on their circular high-speed railway. They found that by adjusting ticket prices in different ways, they could make more money. This shows that considering the type of train and how many people are traveling between certain points (OD levels) is important.
