Steady increase in automobile growth over the last few decades has resulted concurrent growth of vehicle crashes and road fatalities as a consequence. Statistical evidence reveals that such mishaps are noticeably high on two-lane roads primarily because of their unique operational characteristics. This aggravates further in the event of heterogeneity and significant amount of slower vehicles in traffic mix; faster vehicles get impedance from slower ones frequently, while searching for an acceptable gap and they are entrapped inside platoons. Thus, a few drivers of delayed vehicles become impatient and they take considerable amount of risk to pass the impeding vehicle, if such delay is long enough. Accordingly, both, operation and safety of traffic are affected. This calls for an initiative to develop a method of analysing traffic performance considering safety. The present paper provides a methodological blueprint for the purpose of developing an indigenous method to assess traffic performance on such roads based on empirical evidences and experiences with mixed traffic.
