Transbigdata Versions Save

Use ConfigParser to store Mapbox settings, mapboxtoken and imgsavepath are now store at config.ini in transbigdata source code folder.

Update the mobile phone data processing function, See example for detail usage. Add functions:

• transbigdata.mobile_stay_move: Input trajectory data and gridding parameters, identify stay and move.
• transbigdata.mobile_stay_dutation: Input the stay point data to identify the duration during night and day time.
• transbigdata.mobile_identify_home: Identify home location from mobile phone stay data. The rule is to identify the locations with longest duration in night time.
• transbigdata.mobile_identify_work: Identify work location from mobile phone stay data. The rule is to identify the locations with longest duration in day time on weekdays(Average duration should over minhour).
• transbigdata.mobile_plot_activity: Plot the activity plot of individual.

Update the metro model, add functions:

• transbigdata.metro_network: create metro network
• transbigdata.get_shortest_path: Obtain the shortest path with given OD
• transbigdata.get_k_shortest_paths: Obtain the k shortest path with given OD
• transbigdata.get_path_traveltime: Obtain the travel time of the path

See example for detail usage: https://transbigdata.readthedocs.io/en/latest/gallery/Example%205-Modeling%20for%20subway%20network%20topology.html

update plot_map, now the basemap support input self-define mapbox style.

The tbd.plot_map function is added OpenStreetMap as the style 0, which do not need access token any more. imgsavepath and access_token are not neccessarily required now.

update grid_params_optimize method, this algorithm now is changed into PSO to speed up the optimizing process.

fix bug in geohash_decode

fix bug in getadmin

Add the Triangle and hexagon gridding methods, the methods are vectorized and fast:

• Triangle grids: GPS_to_grids_tri and gridid_to_polygon_tri
• Hexagon grids: GPS_to_grids_hexa and gridid_to_polygon_hexa

See Example for details.

v0.3.12:

• Modify code format to fit the standard of flake8.
• Fix bug in getbusdata, now it work perfectly.
