数据集问题

[kakaroy123]

论文中诸如TrafficHZ这些交通速度的数据集是怎么构建成网格形式的呢，每个网格里不会有多条道路么，怎么提取成一个网格对应一个速度的呢？

We applied a grid-based processing approach to the dataset. The original data consists of highly dense road networks, with tens of thousands of roads in a typical city. To manage this complexity, we aggregated the data by averaging the traffic speeds within each grid cell.

就是同一个网格内的所有路段速度求平均么？不用考虑速度的方向么？
