You can check the whole part of the bus until the occurrence of dumpling in the following movie.

Simulation with "Bus Bunching Explained Visually" simulating the occurrence of delay one after another when the bus is delayed - YouTube


When you open the Bus Bunching Explained Visually page, the two buses circle as they circle.


If you move the cursor to the name of the bus displayed in the menu on the left side of the screen, the periphery of the selected bus will glow white.


If you hold the cursor on the menu and left click & hold it, you can stop the bus on the spot and cause a delay in the diamond.


After holding for 1 or 2 seconds and then releasing the mouse, the two buses are running smoothly for a while ....


The number of customers waiting at the bus stop has increased.


The bus arrived at the bus stop and we will get customers, but as the number of customers is larger than usual, it took time to raise and lower, during which time the bus behind me caught up.


Even at the next stop we will catch up with the bus behind while getting on and off.


And it reached 18 people who is the capacity of the bus.


Then, the distance between the cars will be available little by little, so that the back bus also carries a lot of customers.


However, two buses are again in a dumpling state. Once a delay occurs in the bus, the person waiting at the bus stop increases with the delay time, and since the arrival at the bus stop the number of passengers is larger than usual, the stopping time is extended, and even at the next bus stop The number of people waiting for the bus will increase ... ... It will be a negative cycle.


In order to resolve the dumpling operation, it is necessary to have "slack" in the operation system so that multiple vehicles do not stick even if the bus is delayed for a while, but for that purpose it is necessary to increase the number of buses and the working hours of the driver It is necessary to lengthen the cost and to increase the expenses, and there seems to be the present condition that the dumpling operation does not quite resolve.
