Abstract

The invention discloses a mobile terminal positioning-based bus OD data acquisition method and a storage medium. The method comprises steps: based on A-GPS of the mobile terminal, basic trip data areacquired, and original bus data with a user possibly taking a bus for the trip are screened from the basic trip data; according to the rule of a real-time vehicle taking speed and a walking speed of aperson, the vehicle taking state of the user is analyzed, the original bus data are segmented according to the vehicle taking state of the user, and a plurality of sub data sets are obtained; the plurality of sub data sets are combined and ordered according to the time to obtain a first sequence, and a bus route data set with the user trip mode to be the bus in the first sequence is extracted; and based on the sub data sets and the bus route data set, data of getting-on and getting-off bus stops to be transfer stops are removed, and final bus trip data are determined. According to the characteristics of transfer time and a fixed bus route, high-accuracy bus OD data are acquired, the calculation complexity is reduced, errors are reduced, and the bus service level is improved.

Description

technical field

[0001] The invention relates to the technical field of public transport, in particular to a method for acquiring public transport OD data based on mobile terminal positioning and a storage medium. Background technique

[0002] The traffic volume in today's society is increasing sharply, urban traffic is congested, and bad travel conditions seriously affect people's daily life. It has become a consensus to solve the problems of traffic congestion, frequent traffic accidents and environmental pollution in large and medium-sized cities by giving priority to the development of public transportation. All countries in the world have used advanced technology to improve the bus operating environment, invested a lot of manpower and material resources in the research of intelligent public transport systems, and have achieved remarkable results. At present, it is used in the fields of bus positioning, vehicle monitoring, automatic driving, computer-aided dispatching, e...

Examples

Embodiment 1

[0056] The present invention provides a method for acquiring bus OD data based on mobile terminal positioning, figure 1 It is a flow chart of the public transport OD data acquisition method based on mobile terminal positioning of the present invention, such as figure 1 As shown, the method for obtaining bus OD data based on mobile terminal positioning includes:

[0057] S10, collect basic travel data based on the A-GPS of the mobile terminal, and filter out original bus data that the user may travel by bus from the basic travel data.

[0058] Before step S10, the first walking speed of the person is preset, and the first walking speed is 3.6 km / h, that is, it takes 18 seconds for the pedestrian to walk 60 feet. Pre-set the site range threshold for the user to take the bus stop, the site range threshold is 200 meters, that is, the area of ​​a sphere centered at any bus station site and the site range threshold (200 meters) as the radius is used as the range that the user may u...

Embodiment 2

[0168] The present invention also provides a mobile terminal, the mobile terminal 100 includes a processor 1, a memory 2, a GPS module 3, and an acceleration sensor 4, such as figure 2shown. Wherein, the GPS module adopts A-GPS, which is different from the existing GPS, and uses the positioning technology of the mobile terminal without adding other facilities to quickly track the user's position data; the acceleration sensor is used to obtain the acceleration of the vehicle, of course Capture can also be done with other sensors that enable this functionality, such as accelerometers. figure 2 Only some of the components of the mobile terminal 100 are shown, but it should be understood that implementation of all of the illustrated components is not required, and more or fewer components may instead be implemented.

[0169] The memory 2 may be an internal storage unit of the mobile terminal in some embodiments, such as a memory of the mobile terminal. The memory 2 may also be...

Embodiment 3

[0206] The present invention also provides a computer-readable storage medium, the computer-readable storage medium stores one or more programs, and the one or more programs can be executed by one or more processors (this embodiment is the processing device 2) to implement the steps in the method for obtaining bus OD data based on mobile terminal positioning in the present invention.

[0207] In summary, the present invention provides a method for acquiring public transport OD data based on mobile terminal positioning and a storage medium. The method for acquiring public transport OD data based on mobile terminal positioning includes A-GPS based on mobile terminals to collect basic travel data. From the basic travel data, the original bus data that the user may travel by bus is screened out; the user’s riding status is analyzed according to the law of the real-time riding speed and the walking speed of the person, and the original bus data is divided according to the user’s rid...
