Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail.
Embodiment 1
The invention provides a kind of online traffic simulation method, based on traffic simulation software, traffic simulation refers to: utilize computer modeling technique realistically, dynamically to emulate road traffic flow, reproduce change in time and space and the various traffic behavior such as vehicle accident, traffic control of traffic flow, analyse in depth people, car, the various relations on road and feature, utilize the crux that sunykatuib analysis is gone wrong, it is possible to existing traffic system or modification scheme are optimized.Traffic simulation software is utilized to carry out correlational study, there is low cost, low-risk, the plurality of advantages such as repeatable, and by the constraint of on-the-spot experimental condition, emulation technology oneself become the important means analyzing the research such as traffic stream characteristics and engineering optimization, be also one of the focus of field of traffic in the world.
Commercial traffic simulation software more ripe in the world at present specifically includes that the FLOWSIM etc. of Hispanic AIMSUN, the VlSSIM of Germany, China.In the present embodiment, can be selected for FLOWSIM software.Traffic simulation server system is provided with this simulation software, it is possible to carry out polytype traffic simulation according to the demand of user.
Online traffic simulation method in the present embodiment, as it is shown in figure 1, comprise the steps:
Step S1: receive the traffic simulation request of user.
The client that user uses can be PC or various mobile equipment；Can being provided with a client software on the client, user connects the on-line simulation system of this offer in-circuit emulation service by this client software and sends simulation request；User can also connect this on-line simulation system by browser on the client and send simulation request.When user carries out traffic simulation, between user and this on-line simulation system, the data of transmission often have significantly high commercial value, therefore, can ensure the safety of transmitted data by encrypting means such as (such as: SSL encryption etc.), the traffic simulation request of the user namely received can be encrypted.Meanwhile, this on-line simulation system can provide online traffic simulation service for multiple users simultaneously.User and this on-line simulation system may be located in same LAN, it is also possible to be positioned at the diverse location of network.
In the present embodiment, user accesses the Internet by client computer or other-end equipment, and accesses the Web version of FLOWSIM；The Web service version of described FLOWSIM is based upon in FLOWSIM private network, and this private network is the LAN that software operation side sets up based on existing FLOWSIM server, and it has outside access interface；The user's all kinds of services request on Web version FLOWSIM completes by the FLOWSIM software in server, and is saved in data base.
Step S2: according to the information of described user and described traffic simulation request selecting simulation model.
Generally, in server system, storage has the relevant information of user, and user needs to log in this server system, could use this online service, and this just can obtain the information of institute's login user.Having the service mode of traffic simulation software FLOWSIM, this traffic simulation software FLOWSIM in the server to be mainly and independently run for core with product, FLOWSIM etc. has broad development prospect.The core component of described simulation software FLOWSIM is that applicant is based on, in Southampton University of Southampton transportation research, a set of Microscopic Traffic Simulation Mathematic Model that fuzzy mathematics theory is set up, and this model utilizes fuzzy mathematics theory and substantial amounts of data acquisition basis branch to establish can embody the car-following model of the intrinsic driving behavior of various driver, lane-change model and and road model.Utilize FLOWSIM emulation can accurate simulation road network running status, traffic flow character and signal timing dial, utilize traffic simulation result to plan for real-time route more accurately and provide decision support.Current FLOWSIM model widely uses in China, and develops to 3.0 versions.2000 start, the mixed traffic properties of flow of China has been studied, complete at present in the model calibration of China and verification, and the molecular behavior model of bicycle when establishing mixed traffic flow and pedestrian, make FLOWSIM become unique traffic simulation software gathering around systematic mixed traffic flow behavior model set up based on the road condition data of China.
Now, which kind of can select to take simulation model to service this user according to the information of this user, such as: obtain the tariff information of user, needed for rate remaining in the account of user are not enough to pay this traffic simulation during expense, user will be pointed out to supplement with money, forbid that this user carries out this traffic simulation simultaneously；Sometimes, in order to attract user to use this online traffic simulation service, it is possible to allow some users freely use, but the scale of traffic scene that can emulate, complexity and the function supported can restrictions etc. to some extent.
Generally, different traffic simulations asks the scale of traffic scene, the complexity meeting difference to emulate.Therefore, in order to perform this traffic simulation, the required resource consumed of this on-line simulation system generally can be different.Then, when the remaining inadequate resource of this on-line simulation system is to complete this traffic simulation, it is possible to refuse this traffic simulation, or perform this traffic simulation etc. again when waiting resource abundance.Generally, in order to improve the performance of this on-line simulation system, this on-line simulation system can comprise a cluster, and then suitable machine performs this traffic simulation the information such as the scale of traffic scene to emulate, complexity can be asked to select quantity from cluster according to this traffic simulation；Especially when the scale of this traffic simulation request, complexity are all relatively larger time, in order to better complete this traffic simulation, then a number of machine can be selected in the cluster to be specifically used to this traffic simulation of execution.Accordingly, it would be desirable to information and the request of this traffic simulation in conjunction with user select a suitable simulation model, such that it is able to better complete this traffic simulation task.
Guarantee bandwidth speed, the operation relatively uniprocessor version FLOWSIM that user can ask in client reduces to some extent, and the function of its support specifically includes that to be set up road network geometric model, set up road net data model, set up traffic control scheme and run traffic simulation and return simulation run result.Be there is a definite limitation by Web version FLOWSIM in road network scale simultaneously, to ensure running software and data transmission bauds.
FLOWSIM services national multiple units, it may appear that multi-user shared situation, it is therefore desirable to carry out multi-user management.Data base's aspect, the isolation level of self contained data base scheme is the highest, shares rank minimum, but, this scheme would generally strengthen plant maintenance and the cost of tenant data backup, and hardware cost is also above the situation adopting other schemes.Therefore the SaaS service of FLOWSIM is main adopts shared data bank but isolated data architectural schemes, and all of user is used in conjunction with a data base, but each own respective a set of different data list structure, and be stored in the middle of independent pattern.The program can either save certain cost, also can guarantee that between each user mutually isolated to guarantee data security.
In the present embodiment, the step of the described information according to described user and described traffic simulation request selecting simulation model includes:
Step S21: read desired data for described user from the data list structure individually set up in advance according to the information of described user.
On-line simulation system needs the user that service is different, in order to allow these users not interfere with each other, it is necessary to individually set up a data list structure for each user, is used for storing the information of each user.Such as: tariff information, the type information of user, network speed information between user and server terminal, the positional information of user, conventional traffic simulation data message etc., can therefrom read when needed.
Step S22: read required simulation model information for described user from the simulation model list structure individually set up in advance according to the information of described user；
Generally, the user of one on-line simulation system generally can use the traffic simulation pattern information that some are fixing, such as: similar road network geometric model, similar road net data model, similar traffic control scheme, similar computational resource consumption, the IP address of user and geographical position are general all the same.Therefore, it can on on-line simulation system, preset an independent simulation model list structure, in this simulation model list structure, store the information about simulation model, can therefrom read when needed.
Step S23: determine the simulation model of its correspondence according to described desired data, described required simulation model information and the request of described traffic simulation.
Can individually setting up a data base for each user, the data list structure of namely different users is respectively stored in different data bases；A data base can also be shared, but each user has each independent a set of different data list structure, and be stored in the middle of independent pattern.
Step S3: carry out traffic simulation according to described simulation model.
Due to by traffic simulation software unified plan on the server of operator, after have selected simulation model, it is possible to carry out traffic simulation.Select the Traffic Flow Simulation Models optimum for the request of described traffic simulation, obtain the data needed for described traffic simulation, call described Traffic Flow Simulation Models on the server terminal selected by described simulation model, complete described traffic simulation.
The data of traffic simulation be include modeling, run, result such as shows at the data showing whole traffic simulation process.When user carries out online traffic simulation, real-time for the process of whole traffic simulation is presented to user, allow user when using online traffic simulation, sensation does not have any difference with using traffic simulation software in this locality, such that it is able to this on-line simulation system of use allowing user be more prone to, also reduce the training cost of user simultaneously.
In the prior art, each traffic simulation software is respectively arranged with advantage, has his own strong points.Therefore, the server terminal providing online traffic simulation service can comprise the Traffic Flow Simulation Models that each different traffic simulation software of the prior art provides, so, just can call the optimum Traffic Flow Simulation Models asked for this traffic simulation and carry out traffic simulation, thus convenient for users to use, also reduce user and carry out the cost of traffic simulation.Simultaneously, it is possible to comprise multiple server terminal, this simulation model select suitable server terminal, on this server terminal, then call traffic simulation module complete this traffic simulation.
In the prior art, different traffic simulation software is respectively arranged with advantage, has his own strong points, and emphasis that user emulates is different every time, cause that emulation is preferably selected different every time, optimum traffic simulation software, this adds increased the traffic simulation cost of user, and the online traffic simulation method in the present embodiment can ask the Traffic Flow Simulation Models directly selecting optimum to carry out traffic simulation according to the traffic simulation of user, both convenient for users to use, also reduce user and carry out the cost of traffic simulation.
Due to by traffic simulation software unified plan on the server of operator, be uniformly carried out upgrade service, be able to ensure that between multi-tenant database security isolation simultaneously, it is ensured that information security.After having online i.e. service, FLOWSIM can strengthen operator further with the contact between user, by long term service upholding user's relation；Consumer's risk can be reduced, it is to avoid once sell the satisfaction caused and be unable to reach intended situation；Promote that FLOWSIM simulation software is with the integration between the Internet, accelerate cloud computing introduction speed in FLOWSIM, current FLOWSIM various functions all tends to perfect, customer volume also accumulates gradually, is highly desirable to carry out relevant cloud service to meet the numerous clients demand to convenience, online service；Solve problem of piracy, by the use space of the pirate FLOWSIM of online service compression.
Step S4: give described user by the data feedback of described traffic simulation.
When this on-line simulation system completes this traffic simulation, it is necessary to prompting user related information, for instance: the result of this traffic simulation is fed back to user.Sometimes, the online traffic simulation service of use in order to make user convenient, it is also possible to the process of this traffic simulation is also showed user.
In the prior art, if user wants to use traffic simulation software, generally it is required for buying this traffic simulation software with high cost full price；Simultaneously, restriction due to machine performance, the traffic simulation software of uniprocessor version can emulate the traffic intersection number of traffic scene and complexity is limited, if the traffic intersection number of the traffic scene therefore emulated is relatively big or complexity is higher, being accomplished by buying multiple stage machine to form cluster to install this traffic simulation software, this just further increases user and uses the cost of traffic simulation software.And online traffic simulation method provided by the present invention, by traffic simulating system unified plan on on-line simulation system, it is achieved thereby that the overall process of in-circuit emulation, user full price need not buy traffic simulation software, also without buying machine, this traffic simulation software is installed, it is only necessary to pay according to service condition；And user needs not participate in system maintenance and the upgrading in later stage, this just further saves user and carries out the cost of traffic simulation, simultaneously also more convenient.And the method can accept the simulation request of different user simultaneously, it is also possible to not providing service for different user in the same time, improve the utilization rate of system, this just reduce further user and carries out the cost of traffic simulation；Utilize online traffic simulation method provided by the present invention, multiple traffic simulation software can be rewritten into corresponding online version, so, when user needs to carry out traffic simulation, the online version of most suitable traffic simulation software just can be selected according to the requirement of this traffic simulation, so both enrich the selection of user, also reduce user and carry out the cost of traffic simulation.
Online traffic simulation method in the present embodiment, can according to selecting a traffic simulation pattern for the data needed for the traffic simulation of user's storage and simulation model information in advance, thus providing the user an optimum service of simulation, it is possible to better complete this traffic simulation.
In other some embodiments, described simulation model includes: use load-balancing algorithm to select optimal service device terminal.
User is likely located at any position on network, thus causing that the network speed between the user of some position and on-line simulation system is slower；The distribution of user is often also uneven, for instance: university, the number of users in the city that institute is many would generally compare many.Therefore, in order to better service for user, on-line simulation system can comprise multiple server terminal, these server terminals lay respectively at the diverse location on network, and these server terminals can both be separately provided in line traffic simulation service, for instance: in south China, North China, East China, Midwest is all deployed with server terminal；The area relatively more client can also increase server terminal.It is therefore desirable to comform, multiserver terminal select an optimum server terminal to provide the user service.Thus the use of convenient user, improve service quality.
In-circuit emulation method in the present embodiment comprises multiple server terminal, and these server terminals lay respectively at the diverse location of network, and they can both individually complete traffic simulation, accordingly, it would be desirable to select an optimum server terminal to service for user；When wherein some server terminal breaks down, other server terminal can continue to provide service, this improves the stability of whole system.
Being preferably carried out scheme as one, described optimal service device terminal is: and the server terminal that between user, network speed is the fastest, residue calculating resource is maximum.When the network speed of selected optimal service device terminal, residue calculating resource are still insufficient for this traffic simulation demand, as an optional scheme, the operation that user can ask in client can suitably reduce, such as only support to set up road network geometric model, set up road net data model, set up traffic control scheme and run traffic simulation and return simulation run result, the road network scale that can emulate can be arranged certain restriction simultaneously.
In online traffic simulation method in the present embodiment, containing the multiple server terminals at network distribution, network speed between user and different server terminal is often different, owing to same server terminal can provide service for multiple users simultaneously, when a user needs to carry out traffic simulation, can select the server terminal that between and user, network speed is the fastest, surplus resources is maximum is its service, so can make that user is convenient, complete its traffic simulation task quickly, smoothly, add the satisfaction of user.
Additionally, in this online traffic simulation method, also include the step of charge, the charging method of traditional simulation software is disposable soft ware authorization charge method, and client is by paying account in full, it is thus achieved that software is used uses function and lifelong or this version the right to use.And under SaaS mode, charging method mainly has: the time charge method based on turn-on time, the par fee method based on consumer information consumption figure, based on the subscription method of time period with concentrate the comprehensive mixing fee method of charge method.
FLOWSIM mainly adopts the time charge method based on turn-on time, and its expense mainly needs to consider two parts: fixed cost and variable cost.Fixed cost specifically includes that 1) development cost of traffic simulation software FLOWSIM, including the modular structure of software system, function, interface with realize the human costs such as method；2) hardware cost, the facility such as including main frame, server, router, and the manpower produced in this process and time cost.Variable cost specifically includes that 1) customize cost, the personalized function mainly developed according to different user demands, including interface setting, functional module etc.；2) maintenance cost, FLOWSIM operator needs in software service process, according to corresponding situation carry out software amendment, perfect, safeguard, increase infrastructure etc., this part also includes the training cost to user simultaneously.
FLOWSIM needs to consider Dynamic Pricing strategy simultaneously, determines different price according to different situations such as the real economy situation of user, time and spaces.Such as educational system users such as schools, it may be considered that suitably reduce charge.Dynamic pricing mechanism contributes to FLOWSIM and finds price under uncertain environment so that both parties reach higher market efficiency.
