Scope and Objectives

The objective of this study is to conduct traffic studies that provide a scientific basis for deciding on expansion of the Shantipath.

The study findings and appropriate recommendations evolved in this study are briefly summarized below:
• The 12-hour traffic volume count conducted yielded a traffic volume of the order of 36770 vehicles (i.e. 33788 PCUs)

• The future traffic has been projected assuming a growth rate of 1.5 % per annum.

• The estimates show that the future peak hour traffic on this road stretch would be about 4100 vehicles (i.e. 3683 PCUs) in 2011 while it is expected to touch about 4700 vehicles (i.e. 4235 PCUs) in 2021. Since the developments are expected to stabilize, it is expected that the peak directional flow would be about 55 % of the peak hour flow.

• The journey speeds are around 40 - 42 kmph even during the peak hours. As such, the journey speeds during the off peak period are higher by about 5 kmph as compared to the peak hour flows.

• It is estimated that the future V/C ratio would be around 0.61 in 2011 whereas it would be around 0.71 in 2021. This implies that LOS would reach the category ‘C’ by 2021 which is quite acceptable.

• Based on this study, it is felt that the capacity of Shantipath as it exists today would be quite adequate to cater to the future needs. Therefore, it is recommended to provide additionally only 1.5 m soft shoulders (on either side) immediately for the entire road stretch without any need for undertaking any road widening / capacity augmentation measures till 2021. However, it is mandatory to carry out the routine periodical maintenance and overlay works may be carried out as and when needed.
