Railway in Japan During Rush Hour
by Yoshitaka Araki
◆ On-time operation during rush hour
In metropolitan areas such as Tokyo and Osaka, the terrible congestion of trains and people during the commuting rush-hour seems to be recognized as a kind of common feature for Japan.
I think there are rush-hours during common commuting times in every country. However, in Japan, especially in the metropolitan area which highly depend on the public transportation of railways and subways, there are some sections where the congestion rate exceeds 250%. This is such a high rate of congestion that passengers can't move at all.
On-time operation is essential for safety and quality of service, and this especially applies during rush hour. Each railway company in Japan has ways of mitigating the troubles caused by rush-hour commuters, as well as improving on-time operation. In this article, I'll introduce some of these methods.
Some features located around train facilities to aid on-time and safe train operations are listed below:
*Wide train doors
One of the reason for delays is the time it takes for passengers to get in and out of train cars. Some train cars have been adapted to have doors that are a shoulder-width wider than the standard, which makes it easier for passengers to get in and out of the trains more smoothly.
*Platform screen doors and Automatic operation
Platform screen doors doesn't have a direct relation to on-time operation, but it contributes to the reduction of risk of passengers falling onto the train tracks, which aids on-time trains and safety.
Furthermore, most of the screen doors contain Train Automatic Stopping Control systems, so that trains stop with precision at the right position. This system contributes to on-time operation as it shortens the amount of time necessary for braking, etc. .
*Train protection system - Speed control by ATC (Automatic Train Control)
During rush hour, it is necessary to increase the number of trains so that many passengers can be transported. For smooth operation in such situations, train protection systems, such as signals etc., are essential.
In Japan, most urban transit systems and the Shinkansen (Bullet Train) have ATC, or equivalent equipment, which enables high density transportation.
A quick explanation of ATC in Japan follows:
Most ATC has tracking circuits on the rails which recognize the spaces between trains and sets the speed limit. When trains exceed the speed limit, their speed is automatically reduced. This system also enables trains to stop with proper space between them and others. ATC is different from the recently popular type of systems such as PTC, CBTC, etc., systems which use wireless communication. Most ATC systems were introduced prior to the recently developed digital wireless communication technology, so wireless protection systems are not as popular in Japan. Of course, these newer types of systems have more advantages than the current ones, so some railway companies in Japan are considering introducing them.
*Smooth ticket gate process
In Japan, as in other countries, the purchase of fares using IC cards has been increasing in recent years. When passengers go through the ticket gate, they need to hold their IC card over the readers. If it takes a long time to read the card this can cause congestion in the station before even getting to the platform. The standard for IC cards for transportation in Japan requires that they can be read within 0.2 seconds. In this way, 60 passengers could go through the ticket gate per minute.
The companies' activities toward rush hour traffic consists not only of the facilities, but also service by the employees.
*Controlling the distance between trains
Especially during rush hour, the Railway Control Center adjust the positions of the trains so that their distances will be equal. The main adjustment, especially in cases where the gap between trains has become wider than originally intended, is delaying the departure of preceding-train to shorten the distance between it and the following train.
If the timing of the trains is left widened, passengers at platform will be concentrated when boarding the following one, and that will cause further delays. In addition, the following-trains will have to stop before arriving at the platform to compensate for this delay and once the train stops, it takes time to restart, which can also cause more delays.
An effective countermeasure to prevent these types of issues is for employees to adjust the distance between trains equally.
*Part-time employees during rush hours on platforms
Have you ever gotten your body or belongings stuck in the door when getting on the train, when in a hurry, or just because you got caught in the crowd? There are platform employees positioned during morning rush hour to help support passengers so that they can get in and out of the train cars smoothly. Of course, they are not only there for when the doors open or close, they also are there to answer passenger questions.
◆ Cooperation by Passengers
In the above we discussed some of the ways that train companies are working to alleviate the problems associated with morning rush hour. Needless to say, it is also essential for smooth operations that train companies have the cooperation of riders. I would briefly like to discuss some of the requests made of rush hour commuters in metropolitan Tokyo.
Morning rush hour occurs according to ordinary business hours, so passengers can avoid the terrible crowds by taking a train 1 or 2 hours earlier than the rush will be. To promote this, train companies promote deals for those who are willing to be "early birds". For example, passengers can get rewards if they go through ticket gates before certain times, and they can redeem these points for their daily travels or for shopping.
*One-side Pedestrian Traffic on Concourses
Have you ever bumped into to someone when walking on the concourse because you were both walking on the same side? Many stations in Japan indicate in which direction to walk, right side or left side, to help aid the smooth flow of passengers.
It is essential for passengers to cooperate when they're on the platform, concourse, and trains. Since it's not rules but manners that are necessary, the train companies ask for everyone's cooperation, and have devised content, such as posters. Example related to rush hour are below:
>>> Forming a line on the platform, Smooth boarding of trains
While waiting the next train, passengers are encouraged to form a line on the platform. When getting in and out the train, have you ever had difficulty because of people standing near the door and not moving? In Japan, there are posters asking for cooperation in moving out of the way when the doors are opened.
>>> Personal baggage in the trains
Have you ever been hit by someone else's baggage when standing or sitting on the train? I think many people have had this experience, especially when it is baggage on someone's back, such as backpacks. Railway companies in Japan suggest that passengers carry their baggage on their front, even backpacks. Carrying bags on your back can cause a bother for others in crowded cars but changing the way you carry them can improve flow in train cars.
People with smartphones are increasing, and that can cause various problems in railway facilities. Railway companies ask passengers to observe some cellphone manners, such as refraining from talking in cars, turning off their cellphones near priority seats, and so on. Recently the issues resulting from walking while using smartphones are also increasing, such as people falling on the rails, hitting other passengers, blocking people who are trying to walk, and etc. The companies have asked passengers to be mindful of this while using their smartphones as well. Two examples of these posters follow:
Recently, the diversity of types of work in increasing in Japan. Workers can choose short-time work, staggering their office hours, telecommuting, and so on.
However, at the same time, daily ridership in the metropolitan area is also increasing, as well as sales of commuter train passes.
Regular sales of the commuter passes indicate how many people work regularly in the downtown area of the city and it indicates the concentration of people and economic activities there.
The population in Japan is decreasing, and it's said that even in the metropolitan areas it will start to decline. In addition, the recent sharing economy for cars and bikes, development of autonomous vehicles, etc. are all threats to the vitality of the railway transportation industry. But, from the perspective of recent trends in the use of railways, railway companies will need to continue to solve issues related rush hour congestion.
