SENSITIVITY ANALYSIS FOR VARIATION IN DIRECTIONAL DISTRIBUTION OF TRAFFIC

This study considers the magnitude of variation in directional split and its impact on highway traffic analysis. The study focused on the variational directional distribution during the design or peak volume hours of the year, and carried out sensitivity anslyses to investigate the effect of directional split on highway planning and design calculations. The study suggests a method to determine the 'design directional split' from permanent traffic counter data. It was found that there was a considerable variation in directional split during the peak or highest volume hours of the year. The magnitude of variation in the values of the split observed for diferent peak hours can be in the range of 20% to 40% in a majority of cases of rural roads. These and other findings are discussed.
