In the Netherlands, sometimes overtime was late, I had had to leave the company at eleven o'clock at night. When I drive, I found that a few junctions were all green lights. Even I seen the red lights in far place, when I closed, they turned green. Later, I discovered that intelligent traffic light system is open for me. This is the Dutch traffic lights. Expect for program-controlled, there are sensors and road traffic surveillance systems work together to maximize the speedy passage of the vehicles. It is not a simple job to design intelligent traffic lights, because the designer should take consider into the priority tram, bus priority, Bicycle disabled vehicle priority, pedestrian priority and many other factors. Pedestrian priority button can reduce the waiting time at the intersection. At usually, you do not feel it is good. However, in the winter, you will spontaneously feeling this thing is just too cute. For the priority buttons of bicycles, people with cars and mini- motorcycles and electric cars, operation column accordance with the level of the height of the rider optimum to design to close to the roadside, which make people are easy to touch. The height of the traffic lights which are specifically for bicycle traffic lights and disabled car is also perfectly suited to the needs of people with cars driving. Ergonomic design can be seen everywhere in Europe. Control center of each intersection is in a small roadside cupboard, which has a number. As long as the lights have the problems, the central control room is able to find and troubleshoot at the first time. In order to prudent, I asked my friend who know about it. He told me that doing the traffic lights to the Dutch program is not limited to this point I have observed. At the process, the first step is the sampling. Expect for recording different time traffic frequency , but also need to record all the relevant sections of all traffic-related data include the number of communities near the road, intersection, car ownership , trams bus schedules, schools, factories, hospitals, businesses , shopping centers and so on.
