    This paper presents an intelligent streetlight management system based on LED lamps, designed to facilitate its deployment in existing facilities. The proposed approach, which is based on wireless communication technologies, will minimize the cost of investment of traditional wired systems, which always need civil engineering for burying of cable underground and consequently are more expensive than if the connection of the different nodes is made over the air. The deployed solution will be aware of their surrounding's environmental conditions, a fact that will be approached for the system intelligence in order to learn, and later, apply dynamic rules. The knowledge of real time illumination needs, in terms of instant use of the street in which it is installed, will also feed our system, with the objective of providing tangible solutions to reduce energy consumption according to the contextual needs, an exact calculation of energy consumption and reliable mechanisms for preventive maintenance of facilities. © 2013 by the authors; licensee MDPI, Basel, Switzerland.

    Intelligent vehicle routing problem solver for simulating urban last-mile logistics

    The exponential growth of e-commerce and increasing urbanization have significantly complicated last-mile logistics, making more efficient and sustainable delivery solutions necessary. This study presents a solver for simulating urban last-mile logistics, developed within the framework of the European SENATOR project, which aims to optimize urban logistics. The proposed solution integrates key concepts such as multimodal transportation, time-dependent travel conditions, and driving constraints to enhance delivery efficiency and minimize environmental impact. To evaluate its effectiveness, a pilot study in Zaragoza, Spain, was conducted, simulating three experimental scenarios: 1) Baseline Scenario – Reflecting the current postal delivery operations, 2) Zero Emission Zone (ZEZ) – Assessing delivery performance when restricting access to fuel-powered vehicles in the city center, 3) Urban Consolidation Centre (UCC) – Evaluating the impact of centralized parcel distribution. Each scenario was analyzed under three fleet electrification levels (current composition, 50% electrified fleet, and 100% electrified fleet). The results demonstrate how the solver can simulate and quantify the operational impact of different policies on an urban logistics distributor, such as the implementation of zero-emission zones (leading to fewer packages delivered and an increase in total distance traveled). Furthermore, it shows how this impact varies with different levels of fleet electrification (higher electrification results in a lower negative impact on operations). Furthermore, the developed tool highlights how an urban consolidation center can help reduce the distance traveled by logistics vehicles and, consequently, their emissions.

    Ubiquitous connected train based on train-to-ground and intra-wagon communications capable of providing on trip customized digital services for passengers
    (MDPI AG, 2014-05-05) Salaberria Larrauri, Itziar ; Perallos Ruiz, Asier ; Azpilicueta Fernández de las Heras, Leyre ; Falcone, Francisco; Carballedo Morillo, Roberto ; Angulo Martínez, Ignacio ; Elejoste Larrucea, Maria Pilar; Bahillo, Alfonso ; Astrain Escola, José Javier; Villadangos Alonso, Jesús
    During the last years, the application of different wireless technologies has been explored in order to enable Internet connectivity from vehicles. In addition, the widespread adoption of smartphones by citizens represents a great opportunity to integrate such nomadic devices inside vehicles in order to provide new and personalized on trip services for passengers. In this paper, a proposal of communication architecture to provide the ubiquitous connectivity needed to enhance the smart train concept is presented and preliminarily tested. It combines an intra-wagon communication system based on nomadic devices connected through a Bluetooth Piconet Network with a highly innovative train-to-ground communication system. In order to validate this communication solution, several tests and simulations have been performed and their results are described in this paper. © 2014 by the authors; licensee MDPI, Basel, Switzerland.
