Non-standard unsignalised intersections are very common in European countries with old street networks. The major road often bends at an angle the centre of intersection, which makes intersection non-standard. There few papers about capacity analysis and headway values these intersections, even though non-standard widespread not only Europe but also rest world. Regarding fact that priority (NSU...

Uncontrolled intersections are the intersections where there are no external signs or signals to control the movement of vehicles. In mixed traffic conditions priority rules are often violated by the road users. In All-way-stop-controlled intersections (AWSC), the vehicle should stop themselves before they enter the intersection and should check whether any vehicles are present in the other app...

This paper presents the results of a field test evaluating drivers’ decision making and gap acceptance for a left turn maneuver with opposite traffic; with a focus on the scenario where the turning vehicle is approaching the intersection. Twenty-three participants drove an instrumented vehicle ten times around an extended block turning left at four specific intersections. DGPS and radar data we...

Chapter 17 of the HCM 2000 provides a method for analyzing a two-stage priority process at unsignalized intersections, which provide a wide median in the major street. In the HCM itself, the method is, however, described rather briefly. This could give rise to misunderstandings, and practitioners might avoid using the procedure altogether. This being so, the analytical background of the procedu...

Gap-acceptance capacity models apply to the analysis of minor movements at two-way stop and give-way (yield) sign-controlled intersections, entry streams at roundabouts and opposed (permitted) turns at signalised intersections. The same modelling principles apply to all these cases with different model parameters representing the intersection geometry, control and driver behaviour at different ...
