Demands for bus ridesharing in Shanghai, China, feb 20, 2007.

This is the dataset used in the experiment of paper "Bus-Pooling: A Large-Scale Bus Ridesharing Service". The dataset contains 4,891,984 trajectory data from 4,000 Shanghai taxis from one day (Feb 20, 2007), and 66,369 trips are extracted from the trajectory data. The 100 groups of coordinate sets containing three coordinates as experimental samples are used to compare the effectiveness and efficiency of location-allocation algorithms. Each set of coordinates is the pickup and delivery point randomly extracted from 66,369 trips.

本数据集为论文《Bus-Pooling: A Large-Scale Bus Ridesharing Service》的实验所用数据集。该数据集收录了2007年2月20日单日上海4000辆出租车产生的4,891,984条轨迹数据，并从上述轨迹中提取出66,369次出行行程。本次实验选取100组各含三个坐标点的坐标集作为实验样本，用于对比位置分配（location-allocation）算法的有效性与运行效率；每组坐标集均从上述66,369次出行行程中随机抽取上下客点位构成。
