EFFECT OF LANE WIDTH ON CAPACITY UNDER MIXED TRAFFIC CONDITIONS IN INDIA. DISCUSSION

A discussion of a prior paper with the aforementioned title by S. Chandra and U. Kumar, published in this journal (Volume 129, Number 2, March/April 2003), is presented. The discusser appreciates the exhaustive studies undertaken by the authors for conceptualizing a rather difficult problem of the development of speed volume relationships and estimating the passenger car unit for different types of vehicles under mixed traffic conditions. However, the discusser has some reservations relating to the authors' assumptions, methodology, and findings, which are outlined and detailed herein as points 1-6, and conclusions.
