Does not get caught in the traffic jam of a car · What is a way to not create traffic jam?

When you get to the Golden Week during the Bon Festival season, year-end and New Year holidays, traffic jams will occur that will make you unpopular. In many cases it is a traffic jam due to events such as accidents and traffic concentration, but in recent years the existence of mechanisms causing traffic congestion has come to be known without particular reasons.

Road construction, accidents, and tunnel congestion that occurs at the entrance of the tunnel are known as causes of traffic congestion on daily roads.


However, recent studies have revealed the mystery of unexplained traffic congestion that could not be explained by this alone.


The state of the research is kore. Run a car with a circular course instructed so that all cars circle at a constant speed ......


For example, let's say that one of them, in this case a white car suddenly dropped its speed. Then the following vehicle steps on the brake in an effort to avoid a collision ......


Eventually, that brake generates a brake and a traffic jam occurs, and finally the following car is driven to the point just before the stop.


In one study, cars running on the road are compared to "molecules", traffic at normal times is called "liquid", and traffic at traffic is expressed as "solid."


A car in a state where traffic congestion does not occur and it is flowing well is "liquid", it can run without major damage.


However, once traffic jams occur, traffic conditions change from liquid to solidPhase transitionWake up. This is the theory that the mass of congested cars will lose flexibility and congestion will occur.


In many cases, it is surprisingly a car running at a fast speed to cause traffic congestion. When a car that was flying at a speed faster than other cars catches up with the previous group ......


Naturally it decelerates and joins the flow. At this time, in order to reduce the speed, the driver steps on the brake and the brake lamp lights up.


This deceleration, and further the lighting of the brake light, will brake the driver of the following car to brake. And the car behind it further stepping on the brake ... ... the brake propagates backward in the form of ... so that the speed of the rear of the group drops steadily and a congestion occurs.


And this is the human driver that is creating this situation. According to the survey, 80% to 90% of the drivers think that they are better at driving than the other drivers ... ...


In theory, this is of course not possible. Also, we can selectively pay attention to information among human beingsSelective attentionAlthough there is the ability to say, this is also the aspect that it does not get too much except what I am paying attention to in reverse.


Also, some people become aggressive if you grasp the steering wheel, for example, "Personality changes when you ride a car." The congregation and traffic congestion occur on the road by gathering many such human properties.


Then, how do you do to drive without causing traffic jam? First of all, take sufficient distance between the cars in front and behind. By doing so, even if the previous car suddenly decelerates, we can respond with a margin.


And "to run slowly" is actually one way to prevent traffic jam. Too fast speed someday produces a deceleration, and that's why that deceleration becomes a jam of traffic jam. In order to run slowly, functions such as "cruise control" that keeps the predetermined speed constant are effective.


Some countries are forced to do this halfway. In Belgium and the Netherlands there is a technique called "block driving" which runs slowly with Waza when traffic increases. Sometimes police vehicles may serve this lead.


Automatic driving cars aiming for practical use around 2020 are also one of the technologies expected to be useful for alleviating congestion. Some scientists have found a way to avoid traffic jam from ant behavior patterns. In Hollywood, we adopted a mechanism to automatically change the pattern of signals according to traffic conditions, and it is said that traffic congestion has been reduced by 14%.


Utilization of public transportation will also help to resolve traffic congestion. MIT (Massachusetts Institute of Technology) has announced the research result that 1% of people using cars for mobility use public transportation, the traffic volume is reduced by 18%.


There is also a movement to integrate vehicles and traffic infrastructure at the automaker level to improve road conditions. By the way, Toyota's name is out here, but this movie was created with Toyota's support.


Toyota will release a model called "Corolla iM" equipped with a collision prevention device, an automatic high beam and a lane departure prevention device in North America in September 2016. Not limited to Toyota, increasing the number of vehicles with such functions may mean that accidents are reduced and efficient traveling is possible and congestion is also reduced.
