摘要： 在大数据时代，手机数据因普及率高、采集成本低等优点逐渐受到人们的重视。手机通信运 营商在为手机用户提供通信服务的同时会记录每次服务的时空信息，因此利用手机数据可以挖掘出 用户的位置信息，并应用于城市居民出行OD分布估计。提出以手机数据为基础对城市交通大区之 间OD分布进行估计的方法。利用居民手机数据估计美国旧金山市各交通大区之间的出行分布，并 结合居民出行调查数据对估计结果进行检验。结果显示基于手机数据的出行估计具有较高的可靠 性。

Abstract： When stepping into Big Data Era, mobile phone data attract more and more attentions by transportation domain because of its high penetration rate and low collecting cost. Mobile phone operators record temporal and spatial information of users when providing services. This new data stream turns to be a promising resource to estimate trip distribution pattern due to the fact that each record is able to provide the space-time information. This paper proposes a method to estimate OD distribution among urban mega traffic analysis zones based on mobile phone data mining. A case study of San Francisco, US is selected to implement mobile phone data mining- based OD extraction by proposed method. The outcome is further statistically validated by household survey data. Results reveal that the proposed mobile phone data miningbased approach is able to generate a promising result.
