Deriving Operational Origin-Destination Matrices From Large Scale Mobile Phone Data

Development of origin–destination matrices using mobile phone call data

43 In this research, we propose a methodology to develop OD matrices using mobile phone Call 44 Detail Records (CDR), which consist of time stamped tower locations with caller IDs, and 45 limited traffic counts. CDR from 2.87 million users from Dhaka, Bangladesh over a month and 46 traffic counts from 13 key locations of the city over 3 days of the same period are used in this 47 regard. The in...

Designing Origin-Destination Flow Matrices from Individual Mobile Phone Paths The effect of spatiotemporal filtering on flow measurement

In the past few years the mobile phone data are considered as a useful complementary source of information for human mobility research. In this paper, we focus on the computation of the Origin Destination matrix using mobile phone data. First, a new approach of OD matrix design which takes into account the spatiotemporal heterogeneities of mobile phone data is proposed. Second, some analysis al...

Estimating Origin-Destination flows using opportunistically collected mobile phone location data from one million users in Boston Metropolitan Area

In this paper, we present an algorithm for the analysis of opportunistically collected mobile phone location data to estimate a population’s travel demand in terms of origins and destinations of individual trips. Aggregating the trips from millions individual mobile phone users in the Boston Metropolitan area, we show that the estimated Origin-Destination flows correlate well with the US Census...

Deriving a Large-Scale Taxonomy from Wikipedia

We take the category system inWikipedia as a conceptual network. We label the semantic relations between categories using methods based on connectivity in the network and lexicosyntactic matching. As a result we are able to derive a large scale taxonomy containing a large amount of subsumption, i.e. isa, relations. We evaluate the quality of the created resource by comparing it with ResearchCyc...
