Abstract:Urbani promet predstavlja enega izmed glavnih virov onesnaževanja okolja, velik delež k temu pa prispevajo zastoji v križiščih. Preobremenjenost križišč v času jutranje in popoldanske prometne konice povzroča kolone, pogosta ustavljanja in speljevanja ter spremembe v hitrosti, posledica tega pa so velike količine izpustov vozil. Pri izbiri optimalnega križišča se opiramo na osem splošnih kriterijev, zadnje čase pa se zaradi vedno večjega ozaveščanja o negativnih vplivih na okolje vse več pozornosti posveča okoljskemu kriteriju. Poleg omenjenega je pomemben iz vidika investitorja prav tako tudi ekonomski kriterij, ki se preveri z izračunom ekonomske učinkovitosti projekta. Na podlagi študijskega primera se s simulacijo v računalniškem programu PTV Vissim in izračunom izpustov vozil v računalniškem programu EnViVer določi optimalen tip križišča glede na količine izpustov vozil. Izvedena je simulacija obstoječega križišča, ˝turbo˝ krožnega križišča, ˝target˝ krožnega križišča in ˝flower˝ krožnega križišča. Za variantna križišča se v nadaljevanju izvede še finančna in ekonomska analiza, na podlagi katerih se določi, ali investicija v izgradnjo posameznega tipa križišča izkazuje ekonomsko učinkovitost.
Keywords:vplivi na okolje, izpusti vozil, krožno križišče, mikrosimulacijski model, učinkovitost, finančna in ekonomska analiza

Title:OPTIMAL INTERSECTION FROM AN ENVIRONMENTAL POINT OF VIEW AND ECONOMIC EFFICIENCY
Abstract:Urban traffic represents one of the main sources of environmental pollution and major contributors to this are congestions in junctions. Congested intersections during morning and afternoon rush hour cause columns, frequent stop-start operations and changes in speed, which result in large amounts of vehicle emissions. When selecting the optimal type of intersection we rely on eight general criteria. Recently, due to the increasing awareness of the negative impacts on the environment, we pay more attention to environmental criteria. The important point of view of the investor is also economic criteria, which is verified with calculation of economic efficiency of the project. Based on the case study, a simulation is made with computer program PTV Vissim and then the calculation of vehicle emission with computer program EnViVer to determine the optimal type of junction depending on the quantity of vehicles emissions. A simulation is conducted for existing junction, ˝turbo˝ roundabout, ˝target˝ roundabout and ˝flower˝ roundabout. Financial and economic analyses are then carried out for these types of junctions. Analyses determine whether an investment in the construction of these types of intersection demonstrates an economic efficiency.
Keywords:effects on environment, vehicle emissions, roundabout, microsimulation model, efficiency, financial and economic analysis
