Výzkum se zaměřuje na použití nekonvenčních úprav křižovatek v ČR s cílem zvýšit jejich kapacitu, snížit zdržení a minimalizovat emise. Analýza proběhla pomocí simulací PTV Vissim a modelu emisí MEFA 13 pro udržitelnější dopravu.
Abstract:
The research focuses on the potential use of unconventional intersection modifications that lead to an increase in their capacity, a reduction in the delay time when passing through the intersection, and thus a reduction in emissions of pollutants produced by road traffic in their place and surroundings. The aim of the research is to test the application of these unused alternative modifications at intersections in the Czech Republic in order to permanently increase the efficiency of the transportation system while reducing the negative effects on the environment, public health and climate change while maintaining transport competitiveness. The solution identified locations in the Czech Republic for the implementation and assessment of surveys at capacitively inadequate intersections, for which modifications were proposed without expanding the construction occupation of the intersection within the built-up area, i.e. using the existing space, or with only minimal partial expansion to increase their permeability and thus reduce emissions. The PTV Vissim microsimulation tool was used to assess the overall capacity and efficiency of the existing condition and unconventional modifications. The MEFA 13 emission modelling software, approved by the legislation of the Czech Republic, was used to calculate emissions from road transport. The results will serve to create a good basis for the possibility of implementing unconventional modifications of intersections and their adaptation to specific types of conventional intersections in the conditions of the Czech Republic. The research was carried out within the framework of the DOPRAVA 2020+ programme funded by the state subsidy of the Technology Agency of the Czech Republic and the Ministry of Transport of the Czech Republic.
