  • Principles for a Climate Neutral Road Freight Transport

    This paper is based on research findings within the research project ESOB-RKI, which is carried out by the University of Applied Sciences Erfurt and the Bauhaus University of Weimar. Heavy-duty road freight transport causes about a third of the CO2 emissions of all vehicles in Germany. Consequently, its transformation is crucial for achieving climate goals. Since the largest part of road freight transport should be based on direct use of electricity due to the high efficiency advantages, we focus [...]

  • The Electric Road: Technical, Economic and Environmental Study Carried Out in France

    The EU has ambitious targets to reduce by 40% GHG emissions from road transport by 2030 compared to 1990, then by -55% (Fit for 55), and to reach the carbon neutrality in 2050. Transportation represents 25% of the CO2 emissions in the world, among them 75% from road transport and 40% from freight transport. In the EU, 80% of passengers and 70 to 85% of inland freight transports are on the roads. Decarbonising road transport and fulfiling the CO2 reduction require all achievable solutions, above [...]

  • Development of Solar Pavement in Japan and its Contribution to Carbon Neutrality

    In road paving, solar pavement is being developed worldwide against the backdrop of the Paris Agreement, which set a long-term goal of mitigating climate change by 2050 and beyond, SDGs, carbon neutrality and other initiatives. In addition to providing traveling space, pavement, which covers a certain size of surface area in cities and regions, has the potential to generate new values to create renewable energy. We are developing solar pavement with the aim of developing road paving technology that [...]

  • Location of Warehouses and Routing of Cargo Bikes for Last-Mile Deliveries in Urban Areas

    Urban logistics are not only essential for transporting goods within our cities, they also play a crucial role in the quality of life of city dwellers. Urban freight transport accounts for between 15% and 20% of a city’s total traffic, but it is also responsible for one-third of nitrogen oxide emissions, one-quarter of carbon dioxide emissions and half of fine particle emissions. Today, many city centres are restricted for polluting vehicles, most of which are diesel-powered. It is essential to [...]

  • Cycling in Sarajevo

    Sarajevo is the capital and the biggest city in Bosnia and Herzegovina with urban population of approximately 275.000 and 347.000 in metropolitan area. Geographically, it is narrowly positioned in the valley of river Miljacka and surrounded by the mountains that back in 1984 had been the venue for the Winter Olympics, but more recently, were named as one of the best to-visit mountain biking destinations by National Geographic in 2015 . With its three distinct architectural entities (Ottoman, Austro-Hungarian [...]
