This article surveys the literature on analyses of mobile traffic collected by operators within
their network infrastructure. This is a recently emerged research field, and, apart from a few …

Massive and passive data such as cell phone traces provide samples of the whereabouts
and movements of individuals. These are a potential source of information for models of …

In this paper, we attempt to summarize the impact of technologies, especially intelligent
transportation system (ITS) technologies, on transportation research during the last several …

Traffic volume is a parameter used to quantify demand in transportation studies, and it is
commonly collected by using on-road (fixed) sensors such as inductive loops, cameras, etc …

Long‐distance trips are generally under‐reported in typical household surveys, because of
relative low frequency of these trips. This paper proposes to utilize location data from cellular …

ABSTRACT 1 With the fast-growing wireless-communication market, the cellular positioning
2 technologies are becoming one of the important means to monitoring real-time traffic …

Field measurements from the GSM and UMTS networks are analysed in a road traffic
information context. The measurements indicate a potentially large improvement using …

Traffic speed estimation is a fundamental task for traffic management centers and a critical
element of intelligent transportation systems. For this purpose, various sensors are used to …

Traffic congestion is an important problem faced by Intelligent Transportation Systems (ITS),
requiring models that allow predicting the impact of different solutions on urban traffic flow …

For both travelers and traffic operation centers, especially under extremely large traffic
volumes, full-coverage traffic state monitoring of a major corridor is urgently needed. In the …
