The applicability of the ecological and economic parameters of the microsimulation traffic model in the assessment of urban road reconstruction solutions

Promet je jedan od neizostavnih dijelova urbane sredine te samim razvitkom prometa dolazi do poboljšanja gospodarstva pojedine države i poboljšanja životnih standarda ljudi, ali je i jedan od važnijih čimbenika onečišćenja okoliša što ima negativan utjecaj na zdravlje ljudi. Cestovni promet je jedan od najvećih zagađivača okoliša sa emisijom ispušnih plinova kojima onečišćuje zrak, ali i narušava kvalitetu života zbog buke i vibracija. Pred projektante prometne infrastrukture stavlja se zahtjevan zadatak da pomire suprotstavljene ciljeve razvoja prometne infrastrukture prema prometnoj potražnji s jedne strane i da svojim rješenjima smanje negativne učinke operacionalizacije prometnog sustava. Sukladno tome razvijeni su različiti modeli koji predviđaju razinu buke, aerozagađenja i drugih negativnih posljedica prometa i koji su postali često korišteni alat u ocjeni varijantnih rješenja. U ovom diplomskom radu je ocijenjena primjenjivost ekoloških i ekonomskih parametara koji su rezultat mikrosimulacijskog modeliranja, u ocjeni varijantnih rješenja raskrižja. Promatrani ekološki parametri su parametri areozagađenja, točnije emisije ugljikovog monoksida, emisije dušikovog oksida te emisije hlapivih organskih spojeva, a ekonomski potrošnja goriva. Varijantna rješenja raskrižja u razini koja su promatrana su nesemaforizirano, semaforizirano i kružno raskrižje.Transport is one of the indispensable parts of the urban environment, and the development of transport leads to the improvement of the economy of individual countries and the improvement of people's living standards, but it is also one of the most important factors of environmental pollution, which has a negative impact on people's health. Road traffic is one of the biggest polluters of the environment with the emission of exhaust gases that pollute the air, but also impairs the quality of life due to noise and vibrations. Transport infrastructure designers are faced with the demanding task of reconciling the conflicting goals of transport infrastructure development according to traffic demand on the one hand and reducing the negative effects of operationalizing the transport system with their solutions. Accordingly, various models have been developed that predict the level of noise, air pollution and other negative consequences of traffic and have become a frequently used tool in the evaluation of variant solutions. In this diploma thesis, the applicability of ecological and economic parameters resulting from microsimulation modeling was evaluated in the evaluation of variant intersection solutions. Observed environmental parameters are parameters of air pollution, specifically carbon monoxide emissions, nitrogen oxides emissions and volatile organic compounds emissions, and economic fuel consumption. Variant solutions of level intersections that were observed are intersection without traffic lights, traffic lighted intersection and roundabouts
