Simulation of short lane capacity for reconstruction of intersections

Abstract

When reconstructing traffic-light regulated intersections with over-saturated flows, it is proposed to build short lanes by simultaneously increasing the number of traffic lanes on the entrance to a dedicated direction. However, neither Lithuania’s STR, nor HCM contain any specific methodology for calculation of the capacity of such intersections both in present situation, and forecasting transport flow growth in a short perspective (up to 5 years). The article proposes a methodology for calculation of the capacity of right and left short lanes depending on the length of the traffic lane.
