This 3D map makes Tokyo’s subway system look like a crazy roller coaster ride

A few years ago, Mr. Kuriyama Kuriyama produced a 3D model of Tokyo 's tangled subway system as a graduate student. On his map, a vibrant colored tube shook up and down and ran around each other like a track of the hardest roller coaster.

If you plan to ride these trains, you do not need to bring a barb bag. These are based on reality, but these mountains and valleys do not completely represent the feeling of using the Tokyo subway. Spoon & Tamago covering Japanese design and culture writes like this.

Considering the steep slope and the corner of the wave, I will ask some easy-to-understand questions about the accuracy of the map. @ tookyoreporter pointed me to this graphical map completed in 2003, which shows me the depth of some subway lines. As you can see, these two maps share the quality of many roller coasters. What is going on is that the magnitudes of tilt and rotation are getting worse when they are compressed into facets.

The tools used to measure the depth of the subway - the stairs from the ground to the platform - are not the most scientific. Mr. Kuriyama's model is not a map, but a clever and bright expression of how complex it is to move a large number of people from one place of the city to another.

The roller coaster seems to be a train. It consists of a series of connected cars traveling on orbit. Unlike passenger trains, however, roller coasters do not have their own engines or power sources. With most vehicles, roller coasters move only by inertia and gravity. The only energy consumption occurs in the early stages of a ride when the car is pulled by the first mountain or "lift mountain". The truck starts from a steep rise and accumulates the potential energy in the roller coaster. The rest of the track, valleys, valleys, twists and bends are all designed to change the energy accumulated between potential energy and kinetic energy. As the train moves, the friction gradually disappears until it reaches the end of the trip.

Analysis of a roller coaster needs to fully understand the relationship between physics and roller coasters It is important to first explain and describe the basic structure of a roller coaster. Simply put, the roller coaster is like a passenger train. To explain, the roller coaster is made up of a series of connecting cars moving on orbit. However, unlike a train, the roller coaster has no engine, there is no original power source. - There is no doubt that the roller coaster is the king of the amusement park. Regardless of whether you prefer old-fashioned rattled wood roller coasters, it is full of positive and negative G's and quite unstable feeling. Or you can prepare the latest tube steel roller coaster beforehand. Faster roller coaster including speed of death, hairpin rotation, and of course loops

Roller coasters fall into two main categories: steel roller coasters and wooden roller coasters. Steel roller coasters have steel fences that are often known for their ability to provide smoother driving and reverse circulation than wooden roller coasters. Wooden roller coasters have flat steel trucks and are often known as "air time" by using negative G force when reaching the top of a particular mountain element. New circuit such as I-Box and Topper of Rocky Mountain Construction improves ride comfort of wooden roller coaster, reduces maintenance cost and increases ability to beat rider
