A study on lateral placement and speed of vehicles on two-lane roads

About 3000 data collected on lateral placement and speed of different category of vehicles at various sections of two lane roads are analyzed. For the collection of data, the lane width was divided into segments of 25 cm each, and the placement of left rear wheel of vehicles was noted along with the time taken to travel the trap length (30 m) using a stop watch. Equations were developed between the lateral placement and speed for all categories of vehicles from the field data. The analysis shows that heavy vehicles (truck and bus) 3-wheelers, and slow moving vehicles (bicycles and man-pulled cycle rickshaws) follow a linear relation, while 2-wheelers and cars follow a second degree polynomial relation. The vehicles as a whole follow a second degree polynomial relation. The results of this study give a better insight to the variation in speed with placement.
