Description
Technical field
The present invention relates to computer, internet, communication, artificial intelligence, data mining and decision-making are led in freeway management
Domain application and in particular to a kind of towards highway network operation DSS.
Background technology
2008, it is unimpeded that Jiangsu takes the lead in achieving Free Way Networking in the whole nation, accelerates Jiangsu Province's modern times comprehensive traffic
The formation of transportation system, supports Yangtze River Delta Area economic society fast development demand, has fully demonstrated expressway construction
Basic, guiding and service.For deeply carrying out " science and technology is strong to be handed over " strategy further, advance " four traffic " development,
Since 2012, the networking operation of Jiangsu Province's highway obtains notable achievement with Intelligent Service construction.Mobile phone signaling, defend
The construction of star positioning, the traffic circulation such as video complete monitoring, weather monitoring and ambient condition acquisition system, for networking operation kimonos
Business provides superior traffic behavior sensed condition；Networking data center, dispatching platform, the fortune of reaching the standard grade of Public information issuance platform
Row optimizes operation flow, greatly improves efficiency, validity and the economy of networking operation and service.Jiangsu Province is public at a high speed
Road operation with Intelligent Service from preconsolidation stress, Top-layer Design Method to constructing and implementing, the core technology of employing, design concept and tentatively
Construction achievement is all walked in national antecedent, has had larger popularization demonstration and has been worth.Therefore, on notable performance basis, river
The in-depth construction of Su Sheng Expressway Information is beneficial to improve networking operation and service level further, realizes at a high speed comprehensively
The safety of highway, efficiency and blue target, to practice " making traffic really become the commander of an advance unit or vanguard of development " theory.
But current informatization achievement still fails effectively to support the solution of problems with：
Service Upgrade Problem.The good service of highway is not only embodied in charge efficiency, is more embodied in user complete
The good service experience obtaining in stroke, therefore during networking operation and service, needs to realize the public various in time
Information is issued, the accident of efficiency processes, meets service area service of diversified demand etc..It is necessary in existing advanced perception
On the basis of system and road net data center, excavate freeway traffic flow amount flow direction further, service area stops rule, confirms shadow
Ring risk sources of safety and efficiency etc..
All kinds of facility resource allocation problems.Safety devices, Vehicle Detection facility, information issue the layout of the resources such as facility
Satisfaction operation and demand for services not wasting economic, green principle again should be followed with quantity configuration, this needs considers
Various influence factors carry out decision-making.
Regional Linking scheduling problem.With the growth of economic development and vehicle flowrate, Regional Linking scheduling problem will increasingly
Frequently, in addition can be related to urban road coordination control or other means of transportation.Because networking operation and service have network
Scale effect, scheduling decision is extremely important, but because being related to multiple mechanisms and multiple resources, scheduling decision is again extremely complex.
Road and bridge company operation and service level monitoring and evaluation problem.The operation of freeway net has network size effect
Benefit, but Jiangsu high speed is a road (bridge) company management's pattern, for improving networking operation and service level, needs to improve each road
The operation of bridge company and service level.The evaluation index of one side road and bridge company operation and service level is not yet set up, the opposing party
Face be understand each road and bridge company " operation efficiency how ", " whether the traffic capacity can guarantee that ", " level of service how ",
The problems such as " event find and treatment effeciency how ", simple, periodically, the statistical forms from bottom to top collected are difficult to
Grasp operation and the dynamic change state of service from road network angle in real time.In the face of increasingly complicated Free Way Networking operation kimonos
Business demand, current existing system can not meet management and the decision-making requirements of road network angle.
Therefore on the basis of current Expressway Information, build highway operation and Intelligent Service decision support system
System, is conducive to above unstructured problems and the solution of semi-structured problem, is the action of all kinds of raising operations and service level

Hold a conference or consultation computer, projecting apparatus and large screen display screen, holding a conference or consultation, environment undertissue expert discusses to proposed projects, here
On the basis of formed decision implement scheme, by terminal, scheme is exported；If not needing proposed projects is discussed, directly defeated
Go out scheme；
13) according to the specific operational order of decision implement schemes generation, general family terminal computer is handed down to departments at different levels, group
Knit man power and material's embodiment, determine the evaluation index of scheme implementation result, collect items using network implementation and terminal and comment
The detailed data of valency index, generates evaluation index matrix, and matrix is adopted with the method for fuzzy clustering, step analysis to enforcement effect
Fruit is evaluated；
14) evaluation result according to scheme implementation result, whether interpretation saves as scheme in case library；If it is not, then flowing
Journey terminates；If so, then show that scheme achieves preferable implementation result, case can be saved as subsequently consulting, then integrate
The related data of decision scheme, terminates flow process after being stored in case library.
Further, described step 8) in status early warning index include highway ETC track flow accounting, traffic fortune
Row real time information can query rate, every ten thousand car death rates, roads emergency response starting time, unit volume of the circular flow energy resource consumption decline,
Unit volume of the circular flow carbon emission declines, communications and transportation window has duty the rate of complaints.
Further, described step 10) in decision scheme commented in terms of traffic safety, efficiency, disposal of pollutants three
Valency.
Beneficial effect：The data that the present invention produces when highway network can be runed carries out intelligently parsing, on basis
Under the support of data and knowledge, via the cooperation of modules, data is carried out with the mining analysis of various dimensions, pinpoint the problems and carry
Go out resolution policy, on the basis of current Expressway Information, build highway operation and Intelligent Service decision support
System, can provide qualitative and quantitative suggestion for the action decision of all kinds of raising operations and service level, solve existing skill
Service Upgrade Problem, all kinds of facility resource allocation problem and Regional Linking that art high speed highway information construction achievement exists are adjusted
The unstructured problems such as degree problem and semi-structured problem, contributing to networking, it is safe efficient, blue target with service to run
Realize.
