第六刷中国可视化与可视分析大会OD Trails in Urban Traffic
Vast amounts of urban traffic data are available, e. g
o Taxi trips in New York, Beijing Shenzhen
o Electric scooter tracks in Stuttgart
o Public transportation data in Singapore
Origin-destination(OD) is a fundamental concept in transportation, summarizing
