Microscopic Analysis of Service Delay at Uncontrolled Intersections in Mixed Traffic Conditions
Publication: Journal of Transportation Engineering
Volume 135, Issue 6
Abstract
Several studies are available in the literature on delays at unsignalized intersections under homogeneous and lane-disciplined traffic conditions. The present study introduces a service delay model based on microscopic analysis of delay data under mixed traffic conditions. The data for the study were collected at five uncontrolled intersections located in different parts of India. The data were divided into several parts according to the category of the subject approach vehicle and type of the movement. The conflicting traffic was measured under two categories: light and heavy vehicles. The proportion of heavy vehicles in the conflicting traffic was found to greatly affect the service delay. The proposed service delay model is compared with Kyte’s linear model for service delay estimation.
