Dimensioning of signalized intersections in realistic urban environment
Matej Dobovšek, Drago Sever, 2005, pregledni znanstveni članek

Opis: It is very complex to assure the dynamics of traffic networkin urban environment because of the intensity of traffic flowsand the limited space in the urban area. Signalized intersectionsare undoubtedly very important and frequent element inroad traffic network in urban regions, which greatly influencesthe traffic flow dynamics on each section as in the whole trafficnetwork. The time (delay) a vehicle needs to drive through anintersection directly influences the travel comfort, fuel consumption,traffic pollution and so on. There are many methodsfor dimensioning signalized intersections in the world literature.One of the most applied methods is the HIGHWAY CAPACI1YMANUAL (HCM) 2000 which is based on competentinput traffic flows and other characteristics of traffic signalregulations. The intention of this paper is to establish whetherwe can use the HCM 2000 method directly in the Slovenian realenvironment. Based on the established methodology of researchand limited number of delay measurement in real environmentintersections, there have been some deviations. Thecompletion of the level of service criterion for signalized intersectionshas been proposed, with the intention for more suitabilityestimation in the realistic environment.

Alternative possibilities for defining the length of the separate left-turn lane at the existing level intersection
Tomaž Tollazzi, 2002, pregledni znanstveni članek

Opis: The market offers various computer programs for simulating traffic flows at level intersections whose mathematical background is not known to the end users. Thus the user only enters the data without being aware of how the program works. The results obtained cannot be evaluated properly, which may lead to subjective decisions. The paper presents some simple mathematical alternatives which are used to determine the length of a left-turn lane in a level intersection.
