Mapping cities by transit riders’ trajectories: The case of Brisbane, Australia
利用布里斯班一天的智能卡和GTFS数据，提取了20多万条乘客轨迹，并用“水上乐园”隐喻可视化早晚高峰人流方向，帮助理解公交如何连接城市不同区域。
Emerging non-traditional data (NTD) such as transit agencies' smartcard data and Google's General Transit Feed Specifications (GTFS) have made it easier to unveil the way in which public transit remains relevant, reveal how it facilitates daily mobility, and highlight the way in which different locales across a metropolitan area are connected by public transit. Based on a 24-h period of smartcard data for Brisbane (4 March 2014) allied with GTFS data, we retrieved 205,560 distinct transit riders' trip trajectories by direction (AM/inbound vs. PM/outbound) in Brisbane, Australia. It visualises the trajectories using a waterpark metaphor, in that, like water, people flow downhill.
