N2  - This paper presents an analysis of the existing traffic signal warrants and the corresponding threshold values. The analysis of unsignalized intersections was conducted according to the analytical procedures of Highway capacity manual. Traffic signal optimization was conducted using Synchro software. The results showed that the current warrants are not sufficiently reliable in some situations and can be misleading in the process of selecting the intersection control type. There are three major reasons for insufficient reliability of the existing warrants. First, they are primarily based on total major and subject minor street volumes, so they do not take into account all the possible combinations of volume distribution and composition of the turning maneuvers. Second, they do not make difference between three-leg T intersections and four-leg intersections, and finally they are based only on an overall system operation without regmding the functionality of a specific approach.<p /> <p>Language: en</p>
