TransBigData 针对交通时空大数据处理的Python包

Documentation Status PyPI bilibili

主要功能

TransBigData工具针对时空大数据处理而开发,依托于GeoPandas。TransBigData集成了交通时空大数据处理过程中常用的方法。包括栅格化、数据质量分析、数据预处理、数据集计、轨迹分析、GIS处理、地图底图加载、坐标与距离计算、数据可视化等通用方法。TransBigData也针对出租车GPS数据、共享单车数据、公交GPS数据等多种常见交通时空大数据提供了快速简洁的处理方法。

技术特点

  • 面向交通时空大数据分析不同阶段的处理需求提供不同处理功能。
  • 代码简洁、高效、灵活、易用,通过简短的代码即可实现复杂的数据任务。

更多细节请查看:TransBigData的说明文档

安装

在安装TransBigData之前,请确保已经安装了可用的geopandas包:https://geopandas.org/index.html
如果你已经安装了geopandas,则直接在命令提示符中运行下面代码即可安装

pip install -U transbigdata

使用

下面例子展示如何使用TransBigData工具快速地从出租车GPS数据中提取出行OD:

#导入TransBigData包
import transbigdata as tbd
#读取数据    
import pandas as pd
data = pd.read_csv('TaxiData-Sample.csv',header = None) 
data.columns = ['VehicleNum','time','slon','slat','OpenStatus','Speed'] 
data

使用transbigdata.taxigps_to_od方法,传入对应的列名,即可提取出行OD:

#从GPS数据提取OD
oddata = tbd.taxigps_to_od(data,col = ['VehicleNum','time','slon','slat','OpenStatus'])
oddata

对提取出的OD进行OD的栅格集计:

#定义研究范围
bounds = [113.6,22.4,114.8,22.9]
#输入研究范围边界bounds与栅格宽度accuracy,获取栅格化参数
params = tbd.grid_params(bounds = bounds,accuracy = 1500)
#栅格化OD并集计
od_gdf = tbd.odagg_grid(oddata,params)
od_gdf.plot(column = 'count')
