The research uses a microscopic cellular automaton traffic model (hereafter CA), called the extended LAI model, which contains new functions and is upgraded for the calculation of discharges. Based on the results of traffic simulations, CO2 emissions per kilometre driven were calculated using the model presented by Panis, Broekx and Liu (2006). The results show that the maximum flow of 2122 vehicles/hour is achieved at a maximum speed of 70 km/h and a density of 0.25 vehicles/cell. Between densities of 0.22 and 0.28 vehicles/cell, the traffic flow is in a synchronized phase, with the average speed dropping due to vehicle interaction. At higher densities, congestion occurs, the average speed continues to fall, and the amount of emissions increases. The top speed only affects CO2 emissions at lower densities, but at higher densities, they are much more affected by the acceleration rate. We believe that it would be beneficial to reduce traffic density in times of traffic congestion to achieve the most optimal flow and reduce negative impacts on the environment, for example by encouraging occasional work from home, use of public transport, and trips before or after the expected traffic peaks"},{"@xml:lang":"sl","#text":"Namen prispevka je na primeru 1500 m dolge ceste z enim pasom proučiti značilnosti prometa in ugotoviti, kako na pretok in izpuste ogljikovega dioksida (CO2) vplivajo gostota vozil, omejitev hitrosti in način vožnje. V raziskavi je uporabljen mikroskopski prometni model celični avtomat (v nadaljevanju CA), imenovan razširjeni model LAI, ki vsebuje nove funkcije in je nadgrajen za izračun izpustov. Glede na rezultate prometnih simulacij so z modelom, ki so ga predstavili Panis, Broekx in Liu (2006), izračunani izpusti CO2 na prevožen kilometer. Rezultati kažejo, da je pri največji dovoljeni hitrosti 70 km/h največji pretok 2122 vozil/uro dosežen pri gostoti 0,25 vozila/celico. Med gostotama 0,22 in 0,28 vozila/celico je prometni tok v sinhronizirani fazi, v kateri zaradi medsebojnega delovanja vozil povprečna hitrost pade. Pri višjih gostotah nastajajo zastoji, povprečna hitrost še naprej pada, povečuje se količina izpustov. Najvišja do voljena hitrost vpliva na izpuste CO2 le pri nižjih gostotah, pri višjih pa nanje precej bolj vpliva stopnja pospeška. Menimo, da bi bilo v času prometnih zgostitev koristno zmanjšati gostoto prometa, da bi dosegli čim bolj optimalen pretok in zmanjšali negativne vplive na okolje, na primer s spodbujanjem občasnega dela od doma, uporabe javnega prevoza in potovanj pred ali po predvidenih prometnih konicah"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-NR6MFUYU","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-NR6MFUYU"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-NR6MFUYU/288a1375-8da3-48a3-a878-9a1992a36f3a/PDF"},"edm:rights":{"@rdf:resource":"http://creativecommons.org/licenses/by-sa/4.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Filozofska fakulteta"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-NR6MFUYU/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-NR6MFUYU"}}}}
