Abstract

The study considered the U- turning behaviour of vehicles at mid-block median opening in six lane divided urban road based on gap acceptance. Most of the median openings in India are uncontrolled and un-signalised. This study estimates critical gap or lag, accepted and rejected gaps, vehicle merging time and also a step forward to the modeling of critical gap. Six different sites of Jabalpur city (M.P) were selected for the purpose of field data collection. Data were collected in peak hours using video recording technique at the selected sections which are free from gradient, curves, on street parking, pedestrian movement and effect non-motorized vehicles. The entire traffic are categorised into five different classes such as 2-wheeler, 3-wheeler, Car/SUV, LCVs (light commercial vehicles) and HCVs (Heavy commercial vehicles). Three different methodologies namely traditional method, INAFOGA and Modified Raff’s method are utilized for estimating critical gap. Regression technique is applied for modelling of critical gap using different independent variables for each motorized mode.
