There exist two major contributions of network technology to reduce CO2 levels: reducing the energy consumption of the network itself, and supporting areas of application to reduce CO2 levels. The impact of the latter is potentially higher. Therefore, we present TUDμNet, a testbed for a metropolitan-scale heterogeneous sensor network with hundreds of nodes that help monitor and control CO2 leve...

Currently, the implementation of hybrid proton-exchange membrane fuel cell (PEMFC)-battery-supercapacitor systems for tramways to replace conventional internal combustion engines and reduce greenhouse gas emissions has triggered an upward trend in developing energy management strategies (EMSs) effectively deploy this integration. For purpose, paper introduces a comprehensive EMS consisting high...

Urban transport in countries of East-Central Europe, including the Czech Republic, Poland and Slovakia, played an important role residents’ daily mobility. The underdevelopment individual motorisation contributed to lasting significant public transport. Due operating characteristics electric vehicles, as well emerging fuel crises, a key role, especially large cities. Differences development eco...

Abstract Traditional solutions for tramway interlocking systems are based on physical sensors (balizes) distributed along the infrastructure which detect passing of trams and trigger different actions, like communications with ground system. This approach is not easily scalable maintainable, it costly. The SISTER project designed new architectural addressing previous problems virtualization loc...

This work presents a novel transportation mode detection algorithm that handles the recognition of kick-scooters. In 2015, 10 minutes data from kick-scooter were considered in study, yielding 56% F1-score. Since then, kick-scooters not given much attention. Yet, are now very present urban ecosystem, and their consideration studies has become must. To fill this gap, 4 hours signals collected by ...

In a temporal graph, each edge appears and can be traversed at specific points in time. such reachability of one node from another is naturally captured by the existence path where edges appear chronological order. Inspired optimization bus/metro/tramway schedules public transport network, we consider problem turning collection walks (called trips) directed graph into assigning starting time to...
