Traffic data is one of the key inputs in designing a pavement. The pavement design methods currently available use the defaulted traffic volume for design. The default parameters however vary with traffic volume, axle configuration, level of service and vehicle composition. The parameter under consideration here is the lane distribution factor (LDF) which is used in the design of pavements to identify and use the lane that experiences the maximum amount of vehicle flow as the design lane. While many agencies have specified default LDF values depending on the type of roads, studies have shown that it mainly depends on the traffic volume and speed. The extent of influence exerted by individual highways on the LDF values specified in IRC:37-2018 was estimated in this study. For this purpose, the traffic survey was conducted on two four-lane and one six-lane National Highways, and the corresponding LDF was calculated. It was seen that for the four-lane highways, the average LDF obtained was 0.4 and 0.41 which was closer to the values specified in IRC:37-2018. However, for the six-lane highway, the LDF obtained was only 0.32, whereas the specified value in IRC:37-2018 was 0.6. This shows that the characteristics of the highway play a significant role. It was also seen that the LDF values exhibited marginal differences depending on the spatial and temporal variation associated with the data collection.
