Research ArticleOpen accessIn the abstractRoad Transport Congestion Costs Calculations Adaptation to Engineering ApproachMarjan Lep, Beno MesarecThe article represents so called "engineering" approach for computing the total road transport congestion costs. According to economic welfare theory, the total costs of transport congestion are defined as dead weight loss (DWL) of infrastructure use. With a set of equations DWL could be formulated in a mathematical way. Because such form of equation is not directly applicable for concrete … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 6,813 accessesView PDFCite
