Description

A kind of suspension type traffic system based on urban viaduct
Technical field
The present invention relates to a kind of suspension type traffic system, in particular, relate in particular to a kind of suspension type traffic system based on urban viaduct that can not influence existing traffic that is arranged on overhead bridge floor below based on urban viaduct.
Background technology
Along with the development of Chinese Urbanization, the pressure that city traffic faces is increasing; Whether city has is improved and traffic network easily, is that it becomes modernized urban important symbol.Sixteenth CPC National Congress proposes: " informationization is that China accelerates to realize industrialization and modern inevitable choice; persist in using IT to propel industrialization; promote information-based with industrialization; walk out a new industrialization way high in technological content, good in economic efficiency, low in resources consumption, low in the pollution of the environment, that advantage of human resources is not fully exerted." traffic is as foundation of national economy property industry, energetically apply IT, for realizing that the new great-leap-forward development of traffic has crucial meaning.Informationization is the inevitable choice that realizes transportation modernization.
Public transport is compared with other mode of transportation to have and is taken per capita that road is few, energy resource consumption is low, traffic cost is low, pollution is less relatively, volume of passenger traffic is big; Transport the efficient advantages of higher, it is that one of effective means of solving traffic problems such as big or middle urban traffic blocking becomes common recognition.Along with intelligent transportation system (Intelligent Transportation System; Abbreviation ITS) this gust spring breeze is scraped; It is domestic that to have developed many be background with ITS; The intelligent bus operation command dispatching system of high-tech means such as the utilization communication technology, computer networking technology, sensor technology, GPS, GIS, the generation of these systems and utilization thereof have greatly improved the dispatching efficiency of public transport, have improved the level of service of public transport.But owing to receive the restriction on the prior art, still there are some places not fully up to expectations in these systems, and are too high such as system cost, too high, not high with the compatibility of legacy system to the requirement of user's know-how.
Intelligent transportation system (Intelligent Transportation System; Be called for short ITS); Its predecessor is intelligent vehicle roadnet (Intelligent Vehicle highway system; IVHS) intelligent transportation system applies to whole traffic management system with advanced person's information techenology, data communication transmission technology, electronic sensor technology, electron controls technology and Computer Processing technology etc. are integrated effectively; And set up a kind of on a large scale in, comprehensive playing a role, in real time, comprehensive transportation and management system accurately and efficiently.It improves communications and transportation efficient through harmony, the close fit on people, car, road, and relieving traffic jam improves the road network carrying capacity, and less traffic accident reduces energy resource consumption, alleviates environmental pollution.Be used widely in the present world wide of intelligent transportation system, comprise airport, station passenger flow persuasion system, city traffic intelligent dispatching system, express highway intelligent dispatching system, vehicle in use dispatching management information system, self-propelled vehicle autonomous cruise speed system etc.
For solving large-and-medium size cities crowded traffic problem, domestic and international on the basis of existing railway and highway system, the design and research that has launched the novel traffic pattern.The modern city traffic route adopts stereostropic cross model to divide the guide-car to flow mostly, realizes that the quick of power actuated vehicle passed through in the city, on this basis, disposes subway, light rail or BRT etc., reaches the circulation of personnel's vehicle.Subway is built geology is had relatively high expectations, and light rail or BRT etc. more can take valuable originally path resource.
Since the reform and opening-up, along with Chinese society expanding economy, quickening of urbanization process, the scale of urban public transport is also in continuous expansion.Current, national big and medium-sized cities ubiquity the phenomenon that road is crowded, vehicle stops up, order of traffic is chaotic.According to the data that we grasp, summary is got up, and China's city traffic mainly has following problem at present.
1. self-propelled vehicle increases and accelerates the road capacity deficiency.Recent years, the urban automobile growth rate was rapid, to such an extent as to car, passenger vehicle, the annual of utility van motor bike amplification are more than 15%.And cooresponding with it road area per capita is in low-level state always, though very fast development was arranged in nearly ten years, area rises to 6.6 sq ms by 2.8 sq ms per capita, still is unable to catch up with the growth rate of city traffic amount average annual 20%.
2. road network is unreasonable, and traffic management level is low.The existing city road network of China generally all is that density is low, the arterial highway spacing is excessive, branch road is short, function is chaotic; Belong to low-tach traffic system; Be difficult to adapt to the needs of modern automobile traffic, the modern facilities of traffic control and management and traffic safety management can not satisfy the demand of reality.
3. public transport atrophy, travel components are unreasonable.Since the later stage eighties, the urban transit bus traffic continues atrophy, from the efficiency of operation to the operating management, from the level of service to the economic benefit, comprehensive decline occurred.Though it is many that public transit vehicle and length of line increase, the overall trip speed of public transit vehicle constantly descends, and newly-increased transport power betransported decrease in efficiency and offsets.Because public transport is impacted, the passenger who is transferred out just will seek other trip mode, aggravates the unreasonable of travel components.
The infrastructure construction that public transport is relevant is the basis of public transport development, is the important embodiment of public transport development level, good facility basis has been arranged, the high-caliber service of competence exertion.For this reason, in recent years, the Chinese government constantly put into effect new policy, to solve the contradiction between the too fast and urban highway of Traffic Development, in some large-and-medium size cities, built one after another such as subway, light rail and BRT fast public traffic system to alleviate the urban traffic pressure.But, can find out some problems, such as build subway according to some demonstrations; Subway will bore in construction process and dig at the end, ground, local geologic condition is required relatively harshness, such as just being not suitable for building subway in some cities; And same owing to will dig out a tunnel, lay rail, equipment or the like; And various debugging work, so subway needs long time from beginning to start building to put into effect.As a kind of novel mass transit system; Especially in recent years; The BRT fast public traffic system is all being built in a lot of large-and-medium size cities of China; But the BRT fast public traffic system will be built special travel way to bus, takies traffic route resource on the original just nervous road, and more nervous traffic jam phenomenon is caused in the part.
Current, national big and medium-sized cities ubiquity the phenomenon that road is crowded, vehicle stops up, order of traffic is chaotic.Summary is got up, and our city traffic mainly demonstrates following characteristics and problem at present:
1. city size progressively enlarges, and transport pressure is heavy.Since the reform and opening-up more than 20 year, China has obtained the significant achievements of lasting high-degree economic growth and large-scale cityization.The level of urbanization from 1978 17.9% bring up to 2002 39.1%, increase by 0.88 percentage point every year.And a large amount of personnel's trips and the interflow of commodities are frequent, make city traffic be faced with heavy weight pressure.
2. self-propelled vehicle increases and accelerates the road capacity deficiency.Recent years, the urban automobile growth rate was rapid, to such an extent as to car, passenger vehicle, the annual of utility van motor bike amplification are more than 15%.And cooresponding with it road area per capita is in low-level state always, though very fast development was arranged in nearly ten years, area rises to 6.6 sq ms by 2.8 sq ms per capita, still is unable to catch up with the growth rate of city traffic amount average annual 20%.
3. road network is unreasonable, and traffic management level is low.The existing city road network of China generally all is that density is low, the arterial highway spacing is excessive, branch road is short, function is chaotic; Belong to low-tach traffic system; Be difficult to adapt to the needs of modern automobile traffic, the modern facilities of traffic control and management and traffic safety management can not satisfy the demand of reality.
4. public transport atrophy, travel components are unreasonable.Since the later stage eighties, the urban transit bus traffic continues atrophy, from the efficiency of operation to the operating management, from the level of service to the economic benefit, comprehensive decline occurred.Though it is many that public transit vehicle and length of line increase, the overall trip speed of public transit vehicle constantly descends, and newly-increased transport power betransported decrease in efficiency and offsets.Because public transport is impacted, the passenger who is transferred out just will seek other trip mode, aggravates the unreasonable of travel components.
The urban transport problems of China present stage is the inevitable outcome of socio-economic development, and in the coming years, China will enter society again the continuing of doctrine modernization construction, stable and fast-developing period.In the face of the new period, metropolitan transport time delay simply just can not dealt with problems by widening with newly-built road.Modern city is one day passenger traffic peak period, and passenger's high concentration, to flow to roughly the same passenger flow phenomenon very general, and the vehicle of low freight volume can not satisfy the needs of common people's trip far away.
Modern city needs the modern transportation system that a life phase modernized with it adapts to, and form a comprehensive traffic general layout with urban development layout hight coordinate.To improve the Advance planning target with adjustment in the recent period and combine.People need a kind of saving the area, and capacity is big, energy savings, little to the pollution of environment, noise is little per capita, takes advantage of safe, comfortable, the novel traffic mode easily and efficiently of seat.
