The advance of GPS tracking technique brings a large amount of trajectory data. To better understand such mobility data, semantic models like “stop/move” (or inferring “activity”, “transportation mode”) recently become a hot topic for trajectory data analy ...
Emergency response services are critical for modern societies. This paper presents a model and a heuristic solution for the optimal deployment of many emergency response units in an urban transportation network and an application for transit mobile repair ...
With the rapidly growing trend in urbanization, sustainable planning and management of urban engineering systems is gaining more importance. The evolution of engineering infrastructure that is related to transportation, built-space, energy, and environment ...
The number of vehicles hitting the road each day is rapidly increasing, and several problems, such as traffic conges- tion or driver safety, can no longer be solved in the same fashion as before. Intelligent transportation systems could potentially solve p ...
In Europe, for the past several decades, we have observed that local urban transportation policies in many cities have been geared at reducing automobile use; at the same time, mobility has become a key aspect of social integration. The massive development ...
Trajectory data play an important role in analyzing real world applications that involve movement features, e.g. natural and social phenomena such as bird migration, transportation management, urban planning and tourism analysis. Such trajectory data are a ...
Smartphones have the capability of recording various kinds of data from built-in sensors such as GPS in a non-intrusive, systematic way. In order to be used as observations for route choice models, the discrete sequences of GPS data need to be associated w ...
Mode choice is influenced by quantitative aspects such as cost and time, but importance should be given to qualitative aspects such as people's attitudes or perceptions towards the different modes as well. These latent characteristics can be integrated int ...
We propose a new class of applications for Intelligent Transportation Systems (ITSs), called collaborative transportation applications that aim at solving transportation problems such as congestion and parking. Specifically, we define two applications: Sma ...
Congestion is a phenomenon that arises in a variety of contexts. The most familiar representation is urban traffic congestion. Nonetheless, phenomenons such as prison cell congestion, hospital bed blocking or, at a cellular scale, ribosome congestion, also ...
