Route search is an application for planning an efficient route via points of interest specified by search terms. Essentially, the search requires to find the fastest route, from the location of the user to a specified destination, through geographical ...

Today municipalities around the world spend millions of dollars to understand the dynamics of their transportation infrastructure. Traditional approaches for traffic data collection rely on a fixed sensor infrastructure (e.g., inductive loop detectors), ...

Accurate Mobile Geographic Information System (GIS) is a major building block of many applications, particularly in Intelligent Transportation Systems (ITS). In this context, GPS provides position information of each vehicle, while immediate surrounding ...

The future-related information mining task for online web resources such as news articles and blogs has been getting more attention due to its potential usefulness in supporting individual's decision making in a world where massive new data are ...

Smartphones with their GPS capabilities allow tracking in numerous scenarios at low costs. Whereas most scenarios need only coarse tracking, real-time tracking of competitors in sport events require fine-granular localization with high refresh ...

The recent introduction of the Apple iPhone 5 and the accompanying iOS6 software environment which, among other changes, replaced the use of the Google Maps API in iOS5 by Apple's own Maps API, has led to significant changes in the user experience with ...

There is a potential privacy breach when users access various location-based social applications on a mobile social network (MSN), e.g., sharing locations with friends. To preserve location privacy, one of the most common methods is to use a coarse or ...

The ability to predict when an individual mobile user will leave his current location and where we will move next enables a myriad of qualitatively different Location-Based Services (LBSes) and applications. To this extent, the present paper proposes a ...

The "Virtual Attack Point" approach for pedestrian navigation, based on a traditional navigation strategy, is introduced and its potential advantages are explored. A user study, using paper-prototyping in the field, is presented. Results of this study ...

The analysis of human location histories is currently getting an increasing attention, due to the widespread usage of geopositioning technologies such as the GPS, and also of online location-based services that allow users to share this information. ...

In this paper we propose a technique to enhance the accuracy of WiFi fingerprint-based localization by imputing uncaught access point (AP) signals of WiFi fingerprints. Two techniques were developed for this; one is to impute uncaught AP signals by ...

Recently, numerous location-based services have been developed for smartphones; among location-based services, proactive location-based services can serve smartphone users based on periodically collected location logs in background. However, these ...

Continued advances and cost reduction in personal mobile devices such as smart phones made them widely used in daily-life practices. Mobile devices can be integrated with a growing set of cheap powerful embedded sensors that enable the emergence of ...

Predictive queries over spatio-temporal data proved to be vital in many location-based services including traffic management, ride sharing, and advertising. In the last few years, one of the most exciting work on spatio-temporal data management is about ...
