بخشی از مقاله انگلیسی: 1 INTRODUCTION TO improve urban mobility, accessibility, and quality of life, understanding how individuals travel and conduct activities has been the major focus of city and transportation planners and geographers [1], [2], [3], [4]. In the past, this was accomplished by collecting survey data in small sample sizes and low frequencies (e.g., planning agencies of metropolitan areas in the developed countries conduct 1 percent household travel survey once or twice in a decade). With the evolution of society and innovation in technology, cities have become more diverse and complex than ever before in the increasingly interconnected world. Today more than half of the global population (54 percent in 2014) lives in urban areas, and it is projected that additional 2.5 billion urban population will be added by 2050 [5]. The conventional methods widely practiced in the transportation-planning field were developed to suit the expensively collected small data, and cannot meet current challenges. It is urgent for urban researchers to look for new approaches to address urban challenges such as traffic congestion, environmental pollution and degradation, and increasing energy consumption and greenhouse emission. With the rise of the ubiquitous sensing technologies, digital human footprints, which are the digital traces that people leave while interacting with cyber-physical spaces ([6], [7]), can be recorded in unprecedentedly massive scale with high frequency and low costs. It brings great opportunity to change the landscape of urban research to a new horizon (e.g., [8], [9], [10], [11]), and requires innovation to link the massive data with urban theory and thinking to derive new urban knowledge, called as urban computing or new urban science [7], [12], [13]. This paper demonstrates the application of big data analytics that translates ubiquitous mobile phone data into planner interpretable human mobility patterns, with Singapore (a city-state) as an example. By developing a data-mining pipeline, we quantify spatial distributions of travel patterns by residents in different parts of the city. The ultimate goal is to help planners efficiently derive urban knowledge from big data to target specific urban areas for future infrastructure and service planning improvement. The rest of the paper is organized as follows. In Section 2, we review the state-of-the-art literature on mining human mobility patterns from mobile phone data. We then present the study area and data in Section 3, including call detail record (CDR), census, and household travel survey data (for validation purpose). In Section 4, we introduce the data-mining methods to extract statistically reliable estimates of individual mobility networks from CDR data. In Section 5, we present measures to quantify the spatial distribution of mobility networks in the urban context. Finally, we discuss the planning implications of the findings for future urban development in Section 6. 2 LITERATURE REVIEW As wireless mobile connectivity has changed the way people communicate, work, and play, mobile phone data can be used to derive the spatiotemporal information of anonymous phone users’ whereabouts for analysis of their mobility patterns [14], [15], [16]. Although such data are often sparse in space and time, the large volume and long observation period of mobile phone data can be used to infer human footprints in unprecedented scale [17], [18], [19]. Blondel et al. [20] review broadly recent progress made by studies on personal mobility, geographical partitioning, urban planning, development and security and privacy issues. Calabrese et al. [21] offer a focused survey on ideas and techniques that apply mobile phone data for urban sensing. In this study, we focus on the use of mobile phone data to understand human mobility. Previous work in this aspect illustrates a pattern of preferential returns to previously visited locations and explorations of new places as a general and universal feature [18], [22], [23], [24]. Based on this feature, it is possible to estimate meaningful human activity locations using mobile phone data. CDRs are not as structured as traditional travel survey data which contains location and time information for meaningful activity destinations, or as precise as GPS data which provides higher frequency and accuracy [25]. However, as a byproduct for billing purposes carried out routinely by mobile service carriers, CDR data can be obtained at a much lower cost and on a greater scale. CDRs can present spatiotemporal information of mobile phone users’ movements at cellular-tower or much finer-grained level, depending on the location positioning technology employed by service carriers. In the following sections, we review in detail on previous studies that use CDR data to derive human mobility in cities. |
