    Three Dimensional Fast Bus Inventor: Using Ultrasonic Warning To Avoid Collision

    2010/8/30 17:56:00 36

    Stereo Fast Bus Ultrasonic Warning


    Recently, the US Foreign Policy magazine took stock of the five worst traffic cities in the world: Moscow in Moscow, Mexico City in Mexico, St Paul in Brazil, Bad Ragaz in Nigeria, and Beijing in China.


    Looking around the major cities in the world, most of them have experienced the process of traffic flow from congestion to congestion. At present, no city has completely solved the problem of road traffic congestion, which has become a worldwide problem. In the existing means of transport, the cost of the subway is too high, and the bus rapid transit (BRT) occupies the road.


    Perhaps in the near future, city drivers need not worry about the huge buses blocking roads and sight, because you can freely walk through their belly without damage. This so-called " Stereo fast bar System model, recently in the thirteenth Beijing. Science Expo I made my debut.


    That sounds very scientific. What does "stereoscopic fast bus" look like? It's like a stilt. Bus Each "stereo fast bar" is divided into 4 sections with 10 meters in length. The height of the bottom of the car is 2.2 meters, the total height is 4.4 to 4.5 meters, the body is "fat" to two lane wide, so that the space under the car body can be parallel to two cars. The image says: "stereo fast bus" is like the air "split leg" small subway or light rail, which is spanned over the motor vehicle lane.


    "Stereo fast bus" is more like a "big cover" running across the motorized lane. "Stereo fast bus" sounds really new, but how much is it feasible? With many questions, Li Yang, the editor in charge of news and vertical crossword last night, interviewed Song Youzhou, the inventor of "three dimensional fast bus", the head of Shenzhen Huashi future parking equipment Co., Ltd.


    Turning to the principle of bus priority


    Question 1: if the fast bus and the car synchronously drive to the intersection, fast bus must turn around, while the car should go straight. How should we deal with this contradiction?


    Song Zhou Zhou: first, we use aluminum alloy on top, so that the body itself is very light, the following is completely steel structure, the weight is basically below. The second problem is that the width of this car is greater than its height, which will offset the problem of heavy weight. In addition, when turning, speed control is used. When turning, it may be about ten kilometers, which will not affect the stability of the car. The turning radius should be between 37 and 38 meters to 40 meters. The turning radius should not be too large, and the turning radius should be turned back and forth. It can be opened on both sides of the train and can be opened on both sides of the train. The turning condition can be the same as that of the BRT traffic regulations. It is called bus priority. The other vehicles stop before turning, and the lights are controlled. After turning over, the other cars go straight ahead, ten seconds later, and the other cars are completely regular, so it has little effect on other vehicles.


    Guardrail Ultrasonic Early warning to improve safety


    Question two: what happens if a car bump into the inner wall of a fast car when it goes through a fast bus?


    Song Youzhou: for example, it crosses two roads on the left lane, which means that these two roads only allow two roads for cars and fast buses. In this case, every section is limited to the tall building gantry. This tall building is not allowed to come up with the gantry truck. Only by taking the two Lane on the right, it is a safety measure to prevent the superelevation. In addition, inside the bus, we will notify the police if the ultrasound is too close to the wall. In another way, we plan to make a semi closed inside the bus, that is, we should build a guardrail close to the inner wall of the bus. This way, when the bus stops between the station and the station, it will be closed at high speed. If you want to start, or when you enter the station, there will be an import and export when the speed drops, so that the chance of scraping between buses and buses will be avoided.
