Embodiment
For enabling above-mentioned purpose, the feature and advantage of the application more become apparent, below in conjunction with the drawings and specific embodiments, the application is described in further detail.
One of core idea of the embodiment of the present application is, the real-time Transmission function of the application's application vehicle GPS signal, realize the real-time online statistics of vehicle origin and destination, and the driving path of vehicle can be generated by path culculating technology according to the information in gps signal, relative to the current manual research statistical carried out this type of information, greatly improve collecting efficiency and the accuracy rate of traffic simulation basic data.
With reference to Fig. 1, show a kind of process flow diagram generating the embodiment of the method for vehicle operation data of the application, specifically can comprise:
Step 101, obtain the passenger carrying status information of vehicle, and according to the origin and destination of described passenger carrying status information record Current vehicle;
In a preferred embodiment of the present application, the passenger carrying status information of described vehicle is extracted and is obtained from the signal that the vehicle GPS positioning equipment of vehicle sends.
In practice, gps signal can comprise vehicles identifications, the date (date), time (Hour Minute Second), longitude, latitude, the information such as passenger carrying status.To receiving gps signal carries out abnormal data cleaning, the data of time anomaly and malposition being rejected, then the gps signal of same vehicle is gathered in chronological order and save.
In a preferred embodiment of the present application, described origin and destination can comprise starting point and settled point, and the step of the described origin and destination according to passenger carrying status information record Current vehicle specifically can comprise following sub-step:
Sub-step S11, when fee register that vehicle configures starts, generating passenger carrying status information is carrying, and when switching to described passenger carrying status, the current location of registration of vehicle is starting point;
Sub-step S12, when fee register that vehicle configures stops, generating passenger carrying status information is empty wagons, and when switching to described complete vehicle curb condition, the current location of registration of vehicle is settled point.
In actual applications, passenger carrying status is obtained by taximeter operation.When fee register is turned down, after namely going up visitor, signal can be sent a GPS terminal by fee register, and the passenger carrying status in GPS information by terminal is set to 1, passes back to center; When fee register rolls up, after namely descending visitor, signal can be sent a GPS terminal by fee register, and the passenger carrying status in GPS information by terminal is set to 0, passes back to information.
By continuous reception vehicle data, namely judge by on-board and off-board place the origin and destination that vehicle travels.Be starting point when passenger carrying status becomes 1 from 0; When passenger carrying status becomes 0 from 1, it is terminal.
The positional information of step 102, acquisition vehicle, and the driving path of Current vehicle is generated according to described positional information;
In a preferred embodiment of the present application, the positional information of described vehicle comprises longitude information and the latitude information of the vehicle GPS positioning equipment transmission of vehicle, and the described step generating the driving path of Current vehicle according to positional information specifically can comprise following sub-step:
The longitude information that sub-step S21, the vehicle GPS positioning equipment receiving described vehicle send and latitude information, locate corresponding location point respectively by transmitting time in preset road network topology information;
Sub-step S22, adjacent two longitude information to be connected by actual section with the location point of latitude information in described road network topology information, to form the driving path of Current vehicle.
In actual applications, according to the longitude information in the gps signal of described vehicle and latitude information, vehicle location point when positioning GPS signal sends in preset road network topology information.Actual section between every two location points, connects into the vehicle running path between this location point; The section that all location point tundish contain is connected successively, generates the complete line bus or train route footpath between vehicle origin and destination.
In actual applications, preset topology information comprises electronic chart, and the section of location point in map is all numbered.Section numbering is the unique identification to section in topology information.
Step 103, the origin and destination of described Current vehicle and driving path are combined as vehicle operation data.
In the preferred case, starting point, driving path and settled point are in turn connected to form the single running data of Current vehicle.
For making those skilled in the art understand the present invention better, below better set forth the implementation procedure of the application by a complete embodiment:
