The circuit load factor real-time computing technique of WIFI hot spot is moved based on public transport

Technical field

The invention belongs to intelligent bus technical field, be specifically related to a kind of circuit load factor real-time computing technique moving WIFI hot spot based on public transport.

Background technology

Bus is the trip mode of domestic how metropolitan major public transportation, carries the travel amount of city nearly half.Along with the continuous growth of motor vehicle, urban transportation imbalance between supply and demand worsens, and the corresponding policy such as grade that country advocates public transport optimization promotes that traveler selects bus trip.Therefore this just has higher requirement to the passenger capacity of public transport and service quality, also it is also proposed corresponding requirement to the reasonably optimizing of public bus network simultaneously.

In view of this, the research at present for the optimal design of public bus network starts, and has initial achievements.But the embodiment of above-mentioned achievement, mostly concentrates on and arrange such as locating device or punch-card device etc. on each bus.Described by this just has in the such as notification number Chinese invention patent application of patent name for " public traffic vehicles schedule control system " that be " CN103093610A ": it is by self-service ticketing and check card by bus, when passenger loading, first check card in card reader, counter works, carries out ridership quantitative statistics.When exceeding this vehicle and being fully loaded with number, illustrate that the passenger of this circuit is more, dispensing device transmits a signal to central controller.The data analysis that central operation device is fed back to by the locating device on bus and dispensing device and calculating, public transit vehicle time interval of setting out of timely arrangement master station and frequency, and the public transit vehicle rotation each other of the different circuit of rational management.The maximum defect of above-mentioned traditional card metering pool mode is: first, plan as a whole high cost.Embody a concentrated reflection of when being optimized for circuit, need using every bar circuit each or be about to the bus that uses all needs to install above-mentioned positioning equipment of checking card, safeguard use all very worthy.Secondly, applicable surface is narrow.Also propose in above-mentioned document, prerequisite to be with " whole self-service ticketing and check card by bus " as object, can meet that each people taking this vehicle is conscious carries out this basic premise of checking card.Unmanned or few people checks card, and is all fatal on the accuracy impact of final statistics.How seeking the public bus network optimal way that a kind of cost performance is higher, while guaranteeing the terseness of statistic processes, can more ensure the accuracy of statistics, is this area compeled technical barrier to be solved nearly ten years.

Summary of the invention

Object of the present invention is for overcoming above-mentioned the deficiencies in the prior art, a kind of circuit load factor real-time computing technique moving WIFI hot spot based on public transport of more efficient quick is provided, it utilizes public transport to move WIFI hot spot as the basic fundamental strong point, to obtain the load factor of current public bus network to judge the design rationality of this public bus network and whether to need to adjust accordingly, finally reach the demand of taking of each line passengers and the optimization balance object of this circuit public transit vehicle allocation schedule; The present invention is widely applicable, more while the terseness guaranteeing statistic processes and low cost, can ensure the accuracy requirement of statistics.

For achieving the above object, present invention employs following technical scheme:

Move a circuit load factor real-time computing technique for WIFI hot spot based on public transport, comprise the following steps:
