Description

An Elevated Public Transportation Operation Scheme

technical field

The invention relates to a bus operation scheme, in particular to an elevated public transportation operation scheme.

Background technique

Since the reform and opening up, the national economy has grown rapidly, and "scientific and technological innovation, independent innovation" has become the mainstream of domestic industrial development. Various fields and national life are gradually developing in the direction of intensive, energy-saving, emission-reducing, and low-carbon. The Chinese government promises to the world that the emission reduction strategy will be an important implementation measure of the national policy, and energy conservation and environmental protection, new energy, and new energy vehicles will be listed as national strategic emerging industries, aiming to achieve sustainable development through energy conservation, emission reduction, and innovation. and solve the climate problem faced by all mankind. With the continuous advancement of my country's urbanization process and the continuous improvement of people's living standards, urban internal traffic is facing unprecedented pressure, and the serious shortage of road resources has become a prominent bottleneck hindering the healthy development of cities. At present, the urban traffic solution of my country's first-tier cities is mainly three-dimensional urban traffic. By changing the original road level intersection into a three-dimensional intersection, ground transportation, rail transportation, and underground transportation have become the main forms of transportation, which has effectively relieved traffic pressure. However, the construction of such transportation facilities requires a large amount of capital investment and a long construction period, especially the implementation of underground projects, which is also restricted by factors such as local geology and landforms. The urbanization process has given birth to the rapid development of the second and third tier cities, but there is a sharp contrast between the shortage of funds and the urgency of road construction. Obviously, the transportation mode of the second- and third-tier cities needs to explore an effective construction plan according to their own characteristics. All kinds of cities regard the trunk line bus as a priority transportation facility for development, but the main obstacle to its construction lies in the demolition and resettlement that must be carried out due to road widening, elevated track laying, and underground excavation. This not only requires huge financial investment, but also causes strong social pressure. Emotion is a very serious challenge to the major urban strategic goal of building a harmonious society. Bus Rapid Transit (BRT for short) is a relatively popular transportation scheme at present. The new public passenger transport system is a large-capacity transportation mode, which realizes rail transit operation services and a unique urban passenger transport system that reaches the service level of light rail. However, this kind of scheme mainly relies on strong administrative management. Judging from the demonstration situation, the actual effect is not satisfactory. A three-dimensional express bus scheme is proposed. The body spans two lanes and has two floors. Cars less than 2 meters high can pass through its "crotch", and the upper space is used to carry passengers. Although this scheme is energy-saving and environmentally friendly, and temporarily relieves traffic congestion, the implementation of this scheme poses a higher challenge to ordinary car drivers. In order to avoid traffic accidents, splitting buses must continue to send out signals at the front and rear of the car to warn the front and rear cars, especially Pay attention to avoid large trucks. And the cheating bus must have a sensing device on the first floor. If it is scratched by a car, a warning will be issued. If it needs to turn, the cheating bus will use an indicator light to prompt the car driving in its "crotch" to respond in time. And car travels in this kind of both sides enclosed space, there is certain potential safety hazard, and chain collision accident easily takes place. According to foreign experience, when public transportation travels faster than private cars, most people will choose buses instead of private cars. Advanced and fast public transportation can guide people to actively participate in green travel. Governments around the world are constantly exploring and improving the current public transportation system, hoping to study a high-quality, high-efficiency, low-energy consumption, low-pollution, and low-cost form of public transportation to relieve urban traffic pressure and reduce vehicle pollutant emissions. Although some progress has been made, there are still technical difficulties that have not been overcome in practical application. It can be seen that only with the help of advanced scientific and technological means and making full use of limited space can urban traffic problems be effectively solved.

Contents of the invention

The purpose of the present invention is to overcome the above deficiencies and provide an elevated public transport operation scheme, which uses modern public transport technology to cooperate with intelligent traffic and operation management, opens up special tracks for public transport and builds new platforms and is equipped with special vehicle rotating devices. It runs opposite to each other on the track, and the vehicles underneath are unimpeded, which realizes the efficient space reuse of the original road, and at the same time uses new energy to drive to achieve zero emissions.

The technical scheme adopted by the present invention to solve its technical problems is: the scheme contains crossbeams, solar panels, brackets, guide wheels, guide rails, tracks, elevated beam piers, and the elevated beam piers are constructed in the center of the road in a row in the shape of "T". ”-shaped and “T”-shaped elevated girder piers are provided with rails on both sides of the top, and the rails are laid along the extension direction of the elevated girder piers. The beam, the solar panel is connected with the elevated beam pier through the beam, and is laid along the extension direction of the support. The vehicle is a new structure electric bus, which is placed on the track. There is a guide wheel inside each tire. The tires are coaxial and engaged with the guide rails in a vertical suspension state, forming an elevated public transportation operation scheme.

The technical principle adopted in the bus operation scheme is: the bus operation scheme uses modern bus technology with intelligent transportation and operation management, opens up dedicated bus tracks and builds new platforms with vehicle rotation devices to achieve efficient space reuse. Elevated girder piers are erected in the center of the road separately, and are factory-produced in the form of steel structures or concrete structures, and transported to the site for installation to support and lay tracks. At the same time, the slope length should be extended according to the requirements of rail vehicles or corresponding standards. The roads on both sides of the elevated girder piers do not need to be deeply excavated and remain in their original state. The track is made of steel girders according to the characteristics and requirements of the vehicle, and it is directly used for the vehicle to realize and exceed the road surface function. It has better braking and driving effects than the ordinary road surface. The elevated beam pier at the intersection should be designed according to regulations or standards The height and slope of the track, etc., so as to cross with road vehicles, the contact surface between the track and the tire can be processed into a rough texture, and anti-skid paint or other materials with strong adhesion can also be laid to enhance the friction between the track surface and the tire. The driving and braking performance of the vehicle; the guide rail is installed on the outer side of the top of the track, made of track steel, guiding the vehicle to drive along the rail, and used as a temporary driving track vehicle in extreme cases. Ordinary rubber tires have noise reduction and vibration reduction , anti-slip and other functions that steel wheels do not have; solar panels are installed on the top of the bracket, and are laid along the line with a width of 3 to 5 meters (according to the demand for output power, combined with investment capacity), which fully solves the problem of no site installation for solar panels. Difficulty, because solar power is very abundant, (if the length of the battery panel is 10,000 meters and the width is 5 meters, it can generate 5,000 kilowatts of electricity, and if there are 30 rail vehicles, the power consumption is only about 3,000 kilowatts, and the surplus is about 2,000 kilowatts) Therefore, battery banks should be built on platforms or locations along the line to store surplus electricity for use in rainy days and nights, and can also supply power to public facilities along the line. Since the vehicle runs on the track, it should use the line to transmit power, and there is no need to install batteries in the vehicle to reduce the weight of the vehicle; in order to facilitate the passengers to get on and off the vehicle and the vehicle to change direction and connect to the rail, the vehicle is built with a new platform and equipped with a special vehicle rotation device. At the same time, The rear of the vehicle is equipped with a special escape device to deal with various emergencies. The vehicle is based on the structure and prototype of an ordinary electric bus. The key point is to install the guide wheels on the inner side of the tire, and to supplement the structure and parts of the vehicle with technical transformation to make it meet the characteristics and requirements of track driving. The vehicle uses ordinary rubber tires. , with noise reduction, vibration reduction, anti-skid and other functions that steel wheels do not have. The guide wheel is similar to the steel wheel of a rail vehicle. The guide wheel is coaxial with the tire, located inside the tire, and engages with the guide rail in a suspended state to guide the vehicle along the track. It can also be used as a temporary wheel when the wheel blows out, ensuring that the vehicle Go safely to a nearby designated place to change tires.

The beneficial effects of the present invention are: the scheme is a brand-new public transportation mode suitable for various cities, especially the arterial roads and central isolation belts in big cities are relatively wide, the roads are long and straight, and there may be several interchanges and interchanges along the way. etc., this method is the most appropriate. This scheme changes the traditional side-by-side two-way track to use the upper space to spread out to achieve efficient space reuse. In the implementation of this scheme, only the middle isolation zone or the yellow line position is used to construct the elevated beam pier, and tracks are laid on both sides of the top of the elevated beam pier to achieve efficient space reuse. The vehicles run on the rails on both sides of the elevated girder pier, in the same direction as the ground vehicles, and the two do not affect each other to achieve barrier-free operation. The implementation of this scheme not only does not occupy the effective area of the road, but gives way to social vehicles, but also reduces the huge compensation and social conflicts caused by house demolition for road widening, and also provides intensive utilization for the planning of new roads. Land resource solutions. The construction cost and period of the project are also much lower than those of the overhead light rail, the demolition and widening of the original road, and the underground transportation, and the cost performance and feasibility are very obvious. It fully embodies the development concept of people-oriented and building a harmonious society, and realizes fashionable, fast, comfortable and safe public transport services.
