Major cities all over the world experiencing a traffic jam. Even cities that do not have public mass transit systems. More severe problems, ayangmaha and Los Angeles metropolitan area is centered around the Washington d.c. Metropolitan section, London England, despite the public buses and the subway system, but it is still very jam traffic. A day to waste time stuck on the street count hours. Until the Bill measures vehicle passes through the central business district in downtown Singapore at the beginning of this year applied and can reduce the bottleneck of traffic down one level until several major cities in Europe, Chan will be going to trial. Traffic measures for vehicle traffic or mass provided a car seat from 2-3 more people to use it with non-use fees and use fees have been introduced in various countries. In the United States, the use of public traffic channels use to store a value variable intervals and as much congestion of traffic. Is in intensive interval (morning-evening) in expensive rate. Another time the traffic light keep one rate. Some of the routes based on traffic congestion, there will be a text label (variable message sign board) let the user to know about traffic congestion and the rate through the duration of the interval and at that time. Even more expensive storage tight car. To keep a car to use and add more congestion to the next. They do this because the value via the pay-by-card so no waste of time, and there is no problem with using that variable change. The third dimension is elevated or underground road tunnel construction. Not a valid traffic problem because even encourage people use more personal cars. Rather than improve or provide a convenient public transportation system quickly. So people leave the car switching freight transport passengers explore the distances do not waste space surface. In the United States has been exploring the reason that causes a traffic jam. As follows: 1. bottleneck road condition, 40% 2. accidents happen on the road 25% 3. the weather. Rain and snow fall 15% 4. with the construction or repair of roads, 10% 5. beat the bad traffic lights 5% 6. There are special events or activities 5% Total 100% From the results of this survey to see if there are changes to the traffic surface traffic bottleneck reduction causes the car to make it the largest deviation change the channel to traffic through Strait of bottlenecks or where an accident on the road. The alumoluai and cooperation only to ease this problem. Domestic Thai if consider the cause of the traffic jam above. Beat the traffic lights is not appropriate and will affect more than traffic. Principles of using traffic lights. Try to make the car go through the fork to get the safest and most in the equal period. When the green light a car should run through the fork, to Gush. Distances between cars (gap) is not very far away from the gap indicates that the vehicle is not continuing to gush over. Should stop to open the car, time in one direction through the intersection. Organized rhythm lights (signal phasing) this car is through the many separate. Some people might dispute that, in each ring of the rhythm lights to have started out at time (starting delay) approximately 1-3 seconds, depending on the availability and the user keeps a car but there are lights that have the time to tell them. Allows users to train and prepare their car out before realizing faster when they receive green lights. At present, the police are quick to wave, a car ran over the entire junction is still far. Keep rhythmic green light range the range is through a few vehicles only, is a wasteland of time lights. A traffic lights system use a continuous link Each fork associated circuits and controlled by a control center. When a car ran through a separate one, and then ran by one constant speed will have a green light signals the rhythm, ran through the next split continuously. This system has come to trial, both in Bangkok and in Chiang Mai, but restrictions on the road in our House is not a blog, it is not very successful. In a quick period of morning and evening Officials also noted that turns off the lights manually instead of automatically releasing the rhythm and often open the green light signal intervals in each direction for a long period to paint a car, go through until there are no tail rows. The loss of a green light should be given to gush through the car. In the United States Problems with traffic jam has been classified as a national issue by the Minister of transport issued by the maronrong defined as the nation's primary placement and doubles strategy of resolving the main reasons 5. As follows:I reduce the congestion in urban areas, by asking for cooperation from the communities in the urban areas in the following story.1. provide the Bill when a car enters a dense urban areas on the floor. By variable rate up to pass through the city as congestion of traffic.2. provide public bus systems to motivate people, quick to use public transport and to reduce the use of personal automobiles.3. ask for cooperation from employers who have employed large, State-of-the-art communication system for contact (tele communication) in order to reduce journey times and rest and work in a different time, sequins.II. promote the development of new technology and to communicate. Broadcast traffic is going fast.1. encourage the Government to provide funds to develop the traffic. Provided the distribution of news and information on traffic conditions (in real time) to the user through the various systems, such as a text label, radio and Internet.2. remove the intelligent transportation system Intelligent Transport System, ITS come help in reducing traffic, traffic problems.3. the operating principle of adjustment when the accident occurred. To be able to distinguish if a couple cars. rapidly by modifying the law and related regulations.III. collaboration to provide competition to solve the problem by.1. Select the street jam a lot 2 – 3 steps and requires investment to solve the problem long term traffic and leave the competition in the process, managed to achieve the goal. 2. find a way to develop State-of-the-art car problems and look for alternative budget sources that will be used to develop.3. the road must have been resolved.
