Gap Acceptance at Non–Standard Unsignalised Intersections

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 (NSUI) differs from standard (SUI) conflict flows, it can be expected headways same as those SUI. Consequently, NSUI This paper gives critical follow-up 3-leg 4-leg collected by on-field measurement. Recommendations for used given, recommended compared SUI NSUI.
