Grau en Informació i Documentació
El títol de grau en Informació i Documentació pertany a la branca de Ciències Socials i Jurídiques, s"imparteix a la Facultat de Geografi a i Història i té una aportació docent provinent, principalment, de tres departaments: Història de la Ciència i Documentació, Història de l"Antiguitat i de la Cultura Escrita, i Informàtica. Aquestes tres vessants donen al títol un caràcter multidisciplinari.
Definición de Algoritmos de Caracterización y Emparejamiento de Huellas Magnéticas para la Re-Identificación de Vehículos en Entornos Interurbanos basados en Sensores Magneto-Resistivos
La gestión del tráfico es una tarea que requiere disponer de la máxima información sobre el estado de las vías de circulación y sobre los vehículos que las utilizan. Esta información se obtiene a través del procesamiento de los datos que ofrecen un gran conjunto de sensores distribuidos sobre la infraestructura y los vehículos que se desea monitorizar. En este contexto, los datos más apreciados son los que permiten conocer los itinerarios individuales de cada vehículo, y son muy pocos los tipos de sensores que pueden ofrecerlos a través de un proceso de re-identificación de vehículos en distintos puntos de la red viaria. Los sensores magnéticos se han aplicado a la detección del tráfico des…
Evaluation of the Use of a City Center through the Use of Bluetooth Sensors Network
In order to achieve the objectives of Smart Cities, public administrations need to take measures to regulate mobility, which undoubtedly requires a high level of information and sensorization. Until the implementation of the connected vehicle takes place, it is still necessary to install sensors to obtain information about mobility. Bluetooth sensors are becoming a useful tool due to the low cost of equipment and installation. The use of Bluetooth sensors in cities, with short distances between sensors, makes it necessary to propose new classification algorithms that allow the trips of pedestrians and vehicles to be differentiated. This article presents the study carried out in the city of …
Acquisition, filtering and toll data processing system for obtaining origin-destination matrix and travel times on highways
This paper presents an acquisition, filtering and real-time toll data processing system that provides a base for resolution and generation of studies and models of behavior on highways. Crossing points estimation, speed calculation, study traffic flow, travel time estimation and stopping points can also be provided. The complexity of processing with supplied data volume makes indispensable a less relevant information filtering. This filtering can be done through indicators such as speed or nullity of fields and a performance improvement job in database level using views, materializations, partitioning and parallelism. A web application called MODA has been developed. This application make e…
Improving similarity measures for re-identification of vehicles using AMR sensors
The use of Anisotropic Magneto-Resistive (AMR) sensors for road traffic monitoring has gained popularity in recent years. The Earth magnetic field variations caused by vehicles passing over this kind of sensors can be measured and used for various purposes, including vehicle re-identification at different sensing zones. AMR sensors provide data that allow the calculation of traffic parameters by using simple signal processing techniques. But when vehicle re-identification is the objective, it is not clear which is the best method to compare the signals from different sensors in order to know whether or not they belong to the same vehicle. This paper presents an experimental study with the o…
