    Ecological Impact of Changes in Transport Organisation in Martin with Using Transport-Planning Software
    (University of Zilina, 2018) Palúch, Ján; Čulík, Kristián; Synák, František; Hammer, Juraj; Mikulski, Jerzy
    Using motor vehicles, which uses fossil fuels, is connected with emissions. The main goal of cities, towns and also of the state is to keep these emissions as low as possible. Vehicles move on a traffic network where they are forced to accelerate and decelerate due to various impacts. Junctions and traffic jams are examples of these impacts. An important task is to build transport networks and junctions where vehicles can cross the junction as quickly as possible without unnecessary delay and a significant change in speed. This can contribute to lower vehicle fuel consumption and thus lower emissions.

    The impact of roof box on fuel consumption
    (University of Zilina, 2017) Synák, František; Rievaj, Vladimír
    Passenger vehicles are major petroleum consumers and contributors of greenhouse gas and criteria pollutant emissions in many countries around the world. The amount of fuel consumed affects the environment, status of health of human population as well as financial costs that are associated with vehicle operation. The roof box is one of the often used vehicle attachments. The aim of the paper is to measure the increase of fuel consumption affected by an installed roof box. The impact of roof box on the increase of fuel consumption is measured at the speeds of 50 km.h-1, 90 km.h-1 and 130 km.h-1. The introduction of the paper describes particular harmful constituents of exhaust gases and their effects. Another part of the article includes the methodology of measurement and its results. The last part of the article involves the evaluation of results and recommendations relating to reduction of the increase of fuel consumption affected by roof box.
