Technical field

The invention belongs to the field of transportation technology and relates to a composite special-shaped flange track system, which is used for urban or inter-city rapid passenger transportation, logistics transportation, etc.

Background technique

Rail transportation has become an important part of economic operations and people's lives, especially high-speed rail, subway, monorail transportation, suspended sky train transportation, etc., which are constantly innovating, developing and improving. Rail transit refers to a type of transportation or transportation system that requires operating vehicles to travel on specific tracks. Common rail transits include traditional railways (national railways, intercity railways and urban railways), subways, light rails and trams. New rail transits include maglev track systems, monorail systems (straddle track systems and suspended track systems) and Automatic passenger rapid transit system, etc. Rail transit plays an important role in solving the traffic congestion problem, but urban traffic congestion has continued unabated. With the increase in economic aggregate and high-quality development, first, China's car ownership will be 302 million in 2021, with an annual increase of 23.5 million, with 79 cities exceeding 1 million, 35 cities exceeding 2 million, and 20 cities exceeding 3 million. 10,000 vehicles, with 7 cities exceeding 4 million and 3 cities exceeding 5 million. Private car use has increased sharply, and more and more residents have 2 to 3 cars per household. Many major cities have also invested in thousands of shared cars. Second, the number of express delivery items in China will exceed 107.8 billion in 2021, with an average of nearly 300 million items per day. The rapid increase in express delivery vehicles has added congestion to already congested cities; third, subways, light rails, straddling monorails, suspended empty rails, and cloud rails There is only one mode of transportation on one line of rail transit, and urban transportation resources are not fully utilized. The actual average operating speed is 20 to 40 kilometers per hour. It is a low operating speed, must stop at every station, and has a large capacity and congestion, with 120 to 320 people per car. , the precious time of 2 to 5 hours commuting every day is wasted on congested roads, which greatly reduces the happiness of citizens. Citizens lack the happiness experience of high-speed, efficient, comfortable and high-end smart public transportation. Therefore, self-driving travel still accounts for a considerable proportion. Therefore, problems such as urban ground traffic congestion, air pollution, high carbon emissions, difficulty in parking, and the rapid increase in logistics and express delivery vehicles have not yet been effectively solved. Traffic congestion in megacities and first- and second-category cities has spread to third-category cities. The cost per kilometer of rail transit is 700-1400 million yuan for subways, 310-420 million yuan for light rail, 210-280 million yuan for straddling monorails, 180-260 million yuan for suspended aerial rails, etc. The investment is huge.

However, at present, rail transit such as light rail, straddling monorail, and suspended sky rail only have a single track and a single passenger function. Due to the bus operation model, urban low-altitude resources are not fully utilized. The construction of a modern smart city needs to find an upper and lower composite rail transit. The upper and lower rails are fully operated for high-speed passenger transportation during traffic peaks. During non-peak traffic peaks, the upper and lower rails passenger transportation and logistics share the rails, so that the city's low-altitude resources can be fully utilized, profit can be achieved, and financial burdens can be reduced; citizens need A high-speed, efficient, safe, comfortable, energy-saving and environmentally friendly high-speed passenger transport that can reach traffic peaks in 1 hour on the ground and 10 minutes on the high-speed composite track to increase public travel, reduce private cars and traffic congestion, reduce air pollution, and reduce carbon emissions.
