N2  - The present paper analyzes the placement behavior of vehicles for mixed traffic conditions on four-lane divided highways in India. The influence oftype of shoulder on lateral placement of vehicles is also studied. Normalapproximation failed to define the observed placement data in the cases of the total stream, cars and heavy vehicles; when data for total pavement width was considered. However, the normal distribution successfully defined the lane-wise lateral distribution of these vehicle categories. Normal and lognormal distributions selectively define the placement behavior for two-wheelers, auto-tractor category and non-motorized vehicles. On sectionsof road with paved shoulders, most of the non-motorized traffic is also significantly influenced by paved shoulders. However, the car traffic remained almost unaffected by the type of shoulder. At comparable traffic volumes, outer lanes carried higher percentage of traffic on sections with paved shoulders as compared to that on sections with earthen shoulders.<p />
