本文是通过将波士顿地区的骑行和步行移动数据对比，对人类非机动化移动特征进行分析。

abstract

During the past 100 years, many large cities around the world prioritized individual transportation in cars over more sustainable and healthier modes of transportation. As a result, traffic jams, air pollution, and fatal accidents are a daily reality in most metropolis, in both developed and developing countries. On the other hand, walking and bicycling are effective means of transportation for short to medium distances that offer advantages to both the city environment and the health of its citizens. While there is a large body of research in modeling and analysis of urban mobility based on motorized vehicles, there is much less research focusing on non-motorized vehicles, and almost no research on comparing pedestrian and cyclist behavior.

机动车（小汽车）带来交通拥堵，空气污染和惨痛的事故，另一方面，步行和骑行是短距离出行的有效方式，并且环境友好，有益于健康。有大量关于机动车的研究，对非机动车的关注较少，对于步行者和骑行者的行为对比研究少之又少。

In this paper, we present a detailed quantitative analysis of two
datasets, for the same period and location, covering pedestrian and bike sharing mobility.
We contrast the mobility patterns in the two modes and discuss their implications.
We show how pedestrian and bike mobility are affected by temperature, precipitation and time of day.
We also analyze the spatial distribution of non-motorized trips in Greater Boston and characterize the associated network of mobility flows with respect to multiple metrics.
This work contributes to a better understanding of the characteristics of non-motorized urban mobility with respect to distance, duration, time of day, spatial distribution, as well as sensitivity to the weather.

本文对两个数据集进行详细的研究。研究主要体现在以下几个方面：

1. 比较两个模式的移动特征，讨论其背后的含义
2. 展示温度、降水量和时间段对于两种移动特征的影响
3. 分析数据集在波士顿的空间分布

• 看完摘要，我可能选择重点关注本文的文献综述部分如何构思，以及第一点的讨论内容，和第三点提到的“characterize the associated network of mobility flows with respect to multiple metrics”是个什么东西。
