Abstract

Rad analizira koliki je utjecaj brzine prometnog toka na emisiju štetnih plinova na autocestama
u Republici Hrvatskoj. Upotrebom softverskog alata Copert Street Level, proučavane su
emisije ugljikovog dioksida, ugljikovog monoksida, dušikovih oksida, lebdećih čestica i
hlapljivih organskih spojeva pri različitim brzinama i scenarijima. Analizirani su scenarij
trenutnog stanja, smanjene operativne brzine i smanjene ograničenja brzine. Rezultati
pokazuju kako se smanjenjem brzine mogu smanjiti emisije pojedinih štetnih plinova, dok se
istovremeno može povećati razina emisije drugih. Evaluacijom rezultata prikazuju se ukupne
emisije plinova na svima autocestama u Republici Hrvatskoj ovisno o svakom scenariju.
Scenarij 0 za analizu podataka uzima propisano ograničenje brzine, scenarij 1 za analizu koristi
operativnu brzinu na autocestama u Republici Hrvatskoj koja je veća od ograničenja brzine, a
scenarij 2 temelji se na smanjenju postojećeg ograničenja brzine od 130 kilometara na sat na
120 kilometara na sat. Rad ističe važnost održavanja optimalne brzine prometnog toka,
izbjegavanje znatno niskih i visokih brzina, poticanje ekološke vožnje i uporabu alternativnih
goriva kako bi se smanjio utjecaj emisije štetnih plinova iz cestovnog prometa na okoliš.

Abstract (english)

The paper analyzes the influence of traffic flow speed on the emission of harmful gases on
highways in the Republic of Croatia. Using the Copert Street Level software tool, emissions of
carbon dioxide, carbon monoxide, nitrogen oxides, particulate matter and volatile organic
compounds were studied at different speeds and scenarios The scenario of the current state,
reduced operating speeds and reduced permitted speeds were analyzed. The results show
that by reducing the speed, the emissions of certain harmful gases can be reduced, while at
the same time the emission level of others can be increased. The paper highlights the
importance of maintaining the optimal speed of the traffic flow, avoiding significantly low and
high speeds, encouraging ecological driving and the use of alternative fuels to reduce the
impact of harmful gas emissions from road traffic on the environment.
