Anirudh, You might want to take a look at the following paper which contains PCU values in the Indian context: Maini & Khan (1999). <a href="http://onlinepubs.trb.org/onlinepubs/circulars/EC018/23_51.pdf"> Discharge Characteristics of Heterogeneous Traffic at Signalized Intersections</a> - See table 7 for PCU values of different vehicle types from a number of studies. And the dissertation: Patil Gopal (2002) " <a href="http://rpinfo.rpi.edu/%7Epatilg/index_files/IITB_master-thesis_Gopal.pdf">CAPACITY ANALYSIS OF SIGNALISED INTERSECTION IN DEVELOPING COUNTRIES</a>" - See tables 5.3-5.5 in particular. I am not sure if these values were used 'dynamically' (ie the values vary depending on the volume) or not. Dynamic PCU values may cause convergence problems within the context of a traffic assignment procedure, particularly when analyzing intersection capacity.
