Description
Technical Field
The invention relates to the technical fields of intelligent transportation, big data cloud computing, automatic driving and intelligent automobiles.
Background
In the world, the existing overall urban morphology, from the space structure to the use division, from the vehicles to the transportation system, all have historically and naturally evolved to date from the civilized morphology of farming and the former industry, the formation of the space structure and the use division is caused by the extensive extension of homogenization in urban housing and industrial and commercial scale concentration, the formation of the vehicles and the transportation system is caused by the customary evolution of the horse vehicle architecture and the small town living transportation morphology, and the large urban diseases are continuously spread and increasingly serious. Compared with the modern large-scale urban civilization with intensive high volume ratio after the industrial era and the automatic digital intelligent technical means which is leap forward after the information era, the current urban form lacks the cooperation innovation with hierarchy transition, the urban system architecture design with order guidance and efficiency optimization is relatively lagged, and the concept and the technology of the cooperation elements in the aspects of the traditional space structure, the use division, the transportation system and the like are relatively slow in progress.
The city morphology of China always follows the trend from planning and design to construction and maintenance and from vehicles to system management, but the continuous learning and replication of the paths of Western civilization has basically reached the limit in many aspects, and the new situation requires us to develop new paths, namely paths without precedent in the world, both in the design concept level and in the scientific and technological engineering level.
The efficiency of a traffic system is improved, the free welfare of human beings is improved, and the constant pursuit of urban civilization innovation is achieved.
The invention is one of the next-generation urban civilization invention series, and the innovation of design ideas and scientific engineering in the aspects of transportation means, transportation modes and management systems is emphatically tried.
Disclosure of Invention
The existing traditional traffic system is gradually realized and matured along with digital innovation such as automatic driving and the like, and the following defects are exposed.
1. In the current urban civilization, traditional vehicles are various in types, different in size and specification, different in performance index and different in automatic digital system, and meanwhile, people with different character qualities, different skill proficiency degrees, different reaction speeds and different psychological qualities are used for driving operation. The higher the diversity of the traffic participants in the traffic system, the higher the possibility of accidents, the poorer the harmony, the more unstable the overall traffic system, and the lower the overall traffic efficiency.
2. Human natural intrinsic instability factors are present in traffic systems in excess, resulting in excessive intrinsic instability of the traffic system. The difference in the mechanical specifications of vehicles can be reduced by industry standards, but human differences are natural and inherent, whether people in or out of a vehicle, whether people responsible for driving operations or traffic control, such as distractions, fatigue, drowsiness, loss of patience, misjudgment, and extreme cases of drunk driving, excessive speed, fighting, and blocking of fire rescue vehicles often occur.
3. People often make a non-overall optimal judgment decision with a wrong grass rate according to insufficient and incomplete local information, for example, a driver mistakenly breaks through an area which cannot be controlled to go ahead due to various reasons due to insufficient information, a traffic persuader guides a vehicle to enter a more congested direction for the purpose of relieving traffic pressure at an intersection, and the vehicle can get congested in an unconventional road in approximately the same time period in a free high-speed passing holiday and lack of overall optimized travel time reservation arrangement.
4. The traffic system elements such as individual traffic participants, vehicles, traffic infrastructure, traffic function organizations and the like are mutually split and mutually fight, and the unity and the harmony of integrity are lacked, so that the systematic efficiency of the traffic system is difficult to be integrally optimized, and only some patches beneficial to the local parts can be printed. For example, a traffic planning and designing mechanism largely sets intersections for forbidding left turn to improve the rigid index of the average traffic speed of cities, so that inconvenience is caused, when a traffic operation and maintenance mechanism organizes road construction, irregular and nonstandard enclosing measures are adopted to make the automatic driving vehicles difficult to safely respond and identify, a traffic monitoring mechanism can only provide empirical and post-event congestion information for traffic participants instead of more reliable information obtained by advanced calculation or real-time calculation, a traffic command mechanism can only send out friendly suggestions for avoiding certain congestion places and fails to provide respectively suitable and integrally planned congestion-avoiding optimized routes for potential passing vehicles, traffic authorities only have access to traffic administration data (as a result) and not to traffic demand data (as a result) and thus can only make empirical estimations or passive reactions when seeking to manage the optimal number of vehicles in a city.
5. People occupy a great deal of time and energy in trivial matters such as driving, license, accident, maintenance, cleaning, parking, vehicle finding and the like, and the economic and social overall loss is caused.
6. In the current planning and designing concept of the intelligent transportation system, in the current scientific research industry of the automatically-driven intelligent automobile, the future prospective and research and development targets are in most cases mixed transportation system forms of various traditional vehicles and various automatically-driven intelligent vehicles, which are not difficult to imagine, the possible mutual interaction states between the traditional vehicles and the automatically-driven intelligent vehicles are almost endless, the possible mutual interaction states between the automatically-driven intelligent vehicles with different performance specifications are almost endless, if all the possible states are designed according to corresponding rules as much as possible, the required specifications of the planning and designing of the transportation system and the function design of the automatically-driven intelligent vehicles become extremely complicated and difficult to be clearly converged, and the complexity is not favorable for ensuring the safety and reliability of the transportation system, the efficiency of the system has to be reduced to ensure safety and reliability, and the collection of evidence and the definition of responsibility in the event of an accident will be very difficult. The design idea of the architecture is limited by a traditional thinking formula and a simple imagination of an eye business mode, the actual realization difficulty is overlarge, the total amount of tasks is difficult to estimate accurately, and the time and capital cost required by research and development are difficult to define, so that a future intelligent transportation system marked by automatic driving of a vehicle is difficult to realize and land in a real time, which is a technical problem which is expected to be solved but not successful all the time in the industry and enterprises for research and development of the intelligent transportation system and research and development of the automatic driving intelligent automobile for many years.
7. Even in the present world of traditional non-automatic driving vehicle, because performance specification is not unified, upgrade and upgrade soon, spare part kind model is various, the vehicle has become quick consumer goods to a certain extent, for the longer asset attribute of other traffic infrastructure of life cycle, the vehicle life cycle is relatively short and almost fall into a "consumptive material", because be difficult to obtain the unified continuous spare part replacement maintenance of specification standard in longer time period, many vehicles are scrapped early or are retrieved, it is terminal that it is not fully used to have several structures and subassembly in fact, its economic benefits does not exert to the biggest.
In order to solve the problems, the invention adopts the following technical scheme:
the vehicles in the traffic system all adopt automatic driving vehicles, the vehicles have uniform performance specifications, including driving performance, detection performance, communication performance, positioning performance, calculation performance, execution performance, data format, instruction format and the like, and the uniform performance specification is a group of uniform performance specifications or a series of groups of uniform performance specifications;
the riding experience of the vehicle such as appearance, interior decoration, space, entertainment and the like can be different, and the purposes of people carrying, goods carrying and the like can be different;
the traffic system brings traffic users, automatic driving vehicles, traffic infrastructures and traffic functions into the system, all traffic system elements with the accessible digital capacity, namely the demand states of all traffic users, the running states of all automatic driving vehicles, the running states of all traffic infrastructures and the working states of all traffic functions, are within the unified control range of the traffic system, the big data of the traffic system elements are processed, and the overall optimization of the traffic system is realized through the overall coordinated calculation and control.
As used herein, "infrastructure" refers to a wide range of infrastructure equipment for public use in connection with intelligent transportation, including building infrastructure such as road tunnels and bridges, communication infrastructure such as antenna base station cables, computing infrastructure such as cloud-side computing equipment, energy infrastructure such as cable tower charging farms, vehicle infrastructure such as shared autonomous vehicles, and the like.
The "traffic function institution" refers to department institutions related to intelligent traffic, such as planning, construction, operation and maintenance, management, law enforcement, and includes traffic planning and design institutions, traffic operation and maintenance institutions, traffic monitoring institutions, traffic command institutions, traffic management institutions, traffic law enforcement agencies, and the like.
The intelligent transportation system of the invention has the following beneficial effects.
1. In a traffic system which totally adopts automatic driving vehicles, the diversity of human driving behaviors is reduced as much as possible, and simultaneously, because the performance specifications of the automatic driving vehicles in the traffic system in the aspects of driving performance, detection performance, communication performance, positioning performance, calculation performance, execution performance, data format, instruction format and the like are unified, the diversity of participants of the traffic system is greatly reduced, and the system is simplified. Research of system science tells us that simplification of the system will bring more stable system performance undoubtedly, and the whole traffic system is more convenient for overall cooperation due to simplification, so that the efficiency of the traffic system is improved.
2. Autonomous vehicles will automatically perform all driving operations in most, if not all, situations. Because the natural unstable factors of people are greatly eliminated from the traffic system, the local parts of the traffic system, namely the respective automatically driven vehicles, the respective traffic infrastructure and the respective traffic function mechanisms, respectively and automatically work mechanically, the requirements of traffic users are only used as the input of the single attribute of the system, the whole traffic system also mechanically and systematically operates and generates the output of traffic behaviors, the influence of the natural instability of people on the system is reduced, for example, the negative influence of the vague nerve, fatigue, errors and the like of people on the traffic system is greatly reduced, the dangerous driving with overhigh speed and the traffic retardation with overlow speed are not possible to occur when the vehicles automatically run according to the speed limit, and the vehicles are also uniformly set to be automatically and preferentially avoiding special vehicles such as fire-fighting rescue and the like.
3. Because the traffic system calculates, monitors, controls and manages the demand states of all traffic users, the running states of all automatic driving vehicles, the running states of all traffic infrastructures and the working states of all traffic functional mechanisms, through the overall coordination, each local part can obtain the clear guidance which is optimal to the whole traffic system based on the global information, the running plan of each vehicle can not be only suggested but also be clear and implemented through calculation and control, for example, vehicles will be automatically scheduled to bypass a closed regulatory region, will automatically accept route-optimized traffic grooming based on explicit information and data calculations, and vehicles scheduled to travel on the road in a certain time set will be automatically assigned coordinated optimized travel times and routes via a unified reservation and orchestration calculation.
4. The traffic system elements are not split and fight each other, and can be integrally unified and coordinated, so that the system efficiency of the traffic system is optimized. The traffic system can not patch the local patches in a stacking mode any more, and the overall progress of the hierarchy transition can be generated. For example, the functions of the traffic planning and designing mechanism, the traffic operation and maintenance mechanism, the traffic monitoring mechanism, the traffic directing mechanism, the traffic management mechanism, the traffic law enforcement mechanism, etc. are all integrated into the concept of the "traffic system", and by collecting, calculating, processing and estimating the big data of the traffic system, including the demand states of all traffic users, the driving states of all automatic driving vehicles, the running states of all traffic infrastructures, the working states of all traffic functions, etc., the traffic operation mechanism can make the automatic optimization and adjustment of the steering limits of each lane at the intersection timely and dynamically according to the traffic demand change at specific time and the traffic path planning of specific vehicles, and the traffic maintenance mechanism can make the road maintenance time and region surrounded by the targeted standardized informatization to facilitate the safe and reliable response recognition of the automatic driving vehicles, the traffic monitoring mechanism can update detailed road condition information such as road maintenance and the like and traffic flow adjustment information of corresponding road sections to a central digital map shared by all vehicles in advance, so that congestion avoidance optimization of the running path planning of all vehicles without rain, silk and muir is brought, the traffic command mechanism can dynamically adjust the traffic path and running control in a large area before bottleneck road resources meet traffic flow peaks and send instructions to corresponding vehicles to realize unified coordination command, and the traffic management mechanism can more accurately calculate the total number of urban vehicles realizing optimal efficiency of a traffic system according to large data required by users and correspondingly control, so that the integrally optimized traffic system can stand at a higher level, the view field is more global, and the effect and the efficiency of urban traffic are considered.
5. Because the transportation system adopts the automatic driving vehicles with uniform performance specifications, a lot of time and energy can be saved in trivial matters such as driving, license, annual inspection, accidents, maintenance, cleaning, parking, vehicle finding and the like by people, the cost of learning adaptation and the like is greatly reduced, the accidents are reduced, the matters such as annual inspection, maintenance and the like can be more automated, the vehicles can automatically execute the trivial matters related to the transportation (such as automatic driving, automatic parking in a parking lot, automatic fuel energy charging, automatic cleaning and maintenance and the like) in most cases, and a lot of matters are not needed (such as the use scene of full automatic driving can not require passengers to have driving licenses and the like), so that the loss of the economic society on the matters related to the transportation is reduced, and the economic and social wholeness benefits are brought.
6. The future expectation and development targets of intelligent transportation systems are fundamentally changed. The automatic driving vehicles with uniform performance specifications are adopted in the traffic system, so that the possible mutual interaction states of the vehicles are greatly reduced, the traffic system is greatly simplified, the required specifications of the traffic system planning design and the automatic driving intelligent vehicle function design are greatly simplified and clearly converged, the safety and the reliability can be improved while the traffic efficiency is improved, the relevant evidence collection and the responsibility confirmation of accidents are relatively clear, the difficulty of the architectural design and the engineering realization of a traffic system is greatly reduced, the total amount of tasks is easier to clearly estimate, enabling future intelligent transportation systems marked by vehicle autopilot to be realized and landed earlier at relatively more specific time and capital costs, therefore, the technical problem which is eagerly solved but is not successfully achieved all the time is tried to be solved by the industry and the enterprise which are developed by the intelligent transportation system and automatically drive the intelligent automobile for many years.
7. The intelligent automobile is more intelligent and more economical. Under the requirement of unified intelligent traffic performance specifications, various facilities, equipment, parts and the like for producing, maintaining, nursing and updating vehicles can be continuously produced and supplied for a longer period of time, the high yield has higher probability to bring low cost, and the automatic driving intelligent vehicle (especially the shared intelligent vehicle with public traffic attributes) has the service life far exceeding that of the traditional vehicle and the life-cycle cost far lower than that of the traditional vehicle in the continuous and low-cost production, maintenance, nursing and updating, so that the objects are used as much as possible, and the economic benefits are more effectively exerted.

In addition to the above unified intelligent traffic performance specifications, the riding experience of the vehicle such as appearance, interior, space, entertainment, etc. may be varied, and the uses of people carrying, cargo carrying, etc. may be varied.
In essence, the vehicles in such an intelligent transportation system are "same automatic driving vehicles", and only have aesthetic designs such as different appearances and interiors, comfort designs such as different entertainment equipment, different space arrangements, different carrying purposes, and the like, such as a leather seat or a cotton seat, a sofa or a cargo compartment, a music sound box or a movie screen.

Therefore, a large intelligent traffic system is established in a fusion manner, and all traffic system elements with accessible digital capacity, namely the demand states of all traffic users, the running states of all automatic driving vehicles, the running states of all traffic infrastructures and the working states of all traffic functional mechanisms, are planned, managed, controlled and monitored in a coordinated manner through the collection, calculation and processing of traffic big data covered by the traffic system elements, so that the overall optimization of the traffic system is formed.
Because all the automatic driving vehicles are adopted in the traffic system, in the scene that the vehicles can completely automatically drive, passengers naturally do not need to consider the problem of driving license, and the automatic driving vehicles are released from the hard driving labor or at least relieved from the labor intensity.
The unified performance specification described herein may be a set of unified performance specifications or a series of multiple sets of unified performance specifications. For example, the vehicle may be a vehicle with a uniform size, a uniform chassis and a uniform power system, or may be divided into a series of small vehicles, medium vehicles and large vehicles, each of which has a uniform size, a uniform chassis and a uniform power system. Thus, the system can respond to various types of traffic demands and has more choices of platformization or modularization.
