Simulation of capacity of roundabouts applying principles of sustainable urban development

Abstract

Standards (STR) valid in Lithuania do not contain methodologies for assessment designing and functioning quality of roundabouts. Normative documents neither of EU nor of other parts of the world contain methodologies for calculation of the capacity of exits from roundabouts. The article analyses the methodology for calculation of the capacity of entrances to / exits from roundabouts, transport time losses and line length, taking the principles of urban sustainable development into consideration.
