Two-lane two-way highways constitute a significant portion of road networks in developing countries. Highway Capacity Manuals developed by various agencies suggest the use of performance measures based on platooning of vehicles for evaluating quality of service provided by two-lane highways. Current practices use a single critical headway for identifying the following vehicles but this has its drawbacks. This paper checks the suitability of headway and speed-based probabilistic approach for Indian condition where traffic is heterogeneous and exhibits weak lane discipline. The new method under consideration is compared with current practices by carrying out correlation analysis with 5 min directional traffic flow rate. Analysis showed significantly higher correlation coefficients for the new method compared to that of currently used methods. The method can identify a greater number of vehicles as followers and is also able to account for “happy to follow” vehicles and “safe drivers.”
