Tracking urban mobility with current heterogeneous sensing capabilities has opened a wide research area on analytical and predictive data-driven models for improvements in transport operations and planning. These improvements are applicable for individual users, service providers and decision-makers. People, vehicles and goods move along the city a...

The 5G promise for ubiquitous communications is expected to be a key enabler for transportation efficiency. However, the consequent increase of both data payload and number of users derived from new Intelligent Transport Systems makes network management even more challenging; an ideal network management will need to be capable of self‐managing fast...

Current real-time data collection systems for urban transportation and mobility allow enhancing digital maps with up-to-date situational information. This information is of great interest for short-term navigation and route planning as well as for medium-to long-term mobility data analysis , as it provides a finer time-varying detail of the urban m...

Significant efforts have been made and are still being made on short-term traffic prediction methods, specially for highway traffic based on punctual measurements. Literature on predicting the spatial distribution of the traffic in urban intersections is, however, very limited. This work presents a novel data-driven prediction algorithm based on Ra...

Novel ubiquitous traffic sensors such as floating car data (FCD) are getting extended due to the use of 24 h connected smartphones and global positioning systems. Road conditions such as travel speeds in each road link and mobility demand can be monitored by measurements coming from moving vehicles consisting of geolocation and speed information wi...

This paper presents a pilot study completed in the framework of the INTERAAC project. The aim of the project is to develop a new human-computer interaction (HCI) solution based on eye-gaze estimation from webcam images for people with motor disorders such as cerebral palsy, neurodegenerative diseases, and spinal cord injury that are otherwise unabl...

Nowadays, interconnected ubiquitous objects are more and more present in different applications as a technical solution to collect, every time and everywhere, great amounts of data which are accessible through the Internet. One interesting area of application is the monitoring of cattle, in order not only to improve the farming working conditions b...

The cutting and punching industrial processes can be conceptualized as material removal methods, where the sheet is being transformed as the running CNC program is being executed by the NC machine. The simulation of such processes has to take into account this increasing complexity of the metal sheet. In this work we introduce a representation base...

Bird migration behaviours and patterns offer invaluable information about environmental evolution of regions. Traditional bird ringing techniques are often used for nature monitoring. A web based geographical visualization and analysis tool is presented in this paper, showing how cartographic data of wetland areas, their vegetation and water facili...

In this paper we present a sheet metal Numerical Control (NC) simulation tool for cutting and punching processes, considering the internal representation of the sheet metal as a 2D complex polygon. The nature of the involved processes in the cutting and punching operations supports the utilisation of Boolean Operations between 2D polygons with full...

Visualization of vector fields plays an important role in research activities nowadays. Web applications allow a fast, multi-platform and multi-device access to data, which results in the need of optimized applications to be implemented in both high and low-performance devices. The computation of trajectories usually repeats calculations due to the...

On-demand public transport satisfies many of the needs that traditional public transport, with fixed predeter- mined routes and schedules, cannot fulfill. Both schemas are able to work together, as it is discussed in this paper, being on- demand services a good alternative in the areas and time inter- vals where low demand makes fixed routes unsust...
