In mixed and no-lane disciplined traffic, the vehicles travel abreast due to the variations in their size and non-standard widths; so it becomes essential to consider both the lateral and linear clearances simultaneously for defining the vehicle’s interaction. In this present study, the impact of median type (width and height) on the lateral gap (shy distance) maintaining behaviour of vehicles are studied. The data is collected from straight mid-block sections of four-lane divided highways with different median facilities at free flow speed condition using a sensor based assembly. It is found that the median height and width have a significant impact on the minimum gape maintained by 95% of the vehicles travelling near to the road edge. Findings of this study can be used, whilst developing and validating the simulation models for such traffic streams and evaluating the safety aspects of the road. Models of linear and lateral clearances are useful for finding influence areas, determining PCUs, safety analysis and development of geometrical design standards.
