They have been with us since 1865 but there are still few things more contentious amongst drivers than speed limits with most people taking a strong view on them one way or the other: either that traffic travels too fast and needs to be controlled by the state or that matters of speed are a judgement call which motorists are responsibly able to mak...

... means that speed-reduction strategies can have quite a significant effect on these emissions, whereas for other pollutants, such as CO and HC, the effect of speed reduction is less clear. Generally speaking, as illustrated in Figure 1, HC emissions reduce with speed, whereas CO and PM ones have the lowest emission profiles at medium speeds. However, these emissions have been steadily falling over the last two decades as shown in Figure 2. ...

Urban traffic crashes may lead to only a few casualties, but may generate severe negative impacts on the surrounding traffic, such as evidently increasing traveling delay and non-essential fuel consumption of third parties (i.e., vehicles not involved in the crash). Such detrimental consequences of urban traffic crashes are usually ignored by the t...
Traffic congestion on roads not only increases the fuel consumption but consequently leads to increase in carbon dioxide emissions, outdoor air pollution as well as increase in the exposure time of the passengers. We analyse the greenhouse gas emissions for road transport sector in Mumbai Metropolitan Region (MMR) using fuel consumption and the veh...

U radu je prikazan uticaj puta i saobraćaja na okolinu u ekonomskom vrednovanju putnih projekata (izradi Prefeasibility studije u Generalnom projektu, odnosno Feasibility studije u Idejnom projektu).U ekonomskom vrednovanju, uloga životne sredine je najčešće do sada izostavljanja, međutim u novom EU uputstvu za CBA i vrednovanje infrastrukturnih projekata analiza ovih troškova i koristi je sastavni deo studije. Navedeni uticaj puta i saobraćaja na okolinu u ekonomskom vrednovanju može biti jednostran (samo kroz komponentu COST) ili dvostran (istovremeno kroz komponentu COST i kroz komponentu BENEFIT). Kroz pregled urađenih studija za velike infrastrukturne objekte u Srbiji i Republici Srpskoj, analiziraće se uključivanje ovih efekata sa navedena dva aspekta. U radu će nakon analize postojeće prakse u izradi Studija opravdanosti u Srbiji biti date preporuke i zaključci.
Abstract: The paper presents the impact of road and traffic on the environment in the economic evaluation of road projects (during the preparation of Prefeasibility study in the Preliminary Design and Feasibility Study in the Conceptual Design). The role of environment has been most frequently omitted in the economic evaluation so far. However, the new EU guide to the CBA and evaluation of infrastructure projects states that the analysis of these costs and benefits should be an integral part of a study. The mentioned impact of road and traffic on the environment in the economic evaluation can be one-sided (regarding only the component of COST) or double-sided (at the same time considering both the component COST and the component BENEFIT). The inclusion of these effects with the two stated aspects will be analyzed through a review of the conducted studies for large infrastructure facilities in Serbia and Republika Srpska. Following the analysis of the existing practices in the preparation of Feasibility Study in Serbia, the paper will provide recommendations and conclusions.
