Passenger car unit (PCU) is a relative weightage factor employed for finding various vehicle units when the traffic flow in the stream is heterogeneous. PCU has continually been a substantial concern in all research studies about estimating the highway capacity. In this study, an attempt has been made to determine PCU values and their variation at different vehicle compositions and carriageway widths. Data on eight straight sections of Shivamogga's NH-369 and NH-69 were used for the analysis. For the determination of the PCU of five individual vehicles, the conventional speed-based area method was used. The coefficients of each vehicle were determined using the Simultaneous Equations Model (SEM). The coefficients determined were used to define the vehicle's speed in a stream included in the PCU computation. Variations of PCUs at supposed compositions are plotted for the chosen 5.5-meter-wide section. For the observed composition, the PCU of a particular vehicle on selected eight straight sections is evaluated. The PCU of a vehicle at observed proportions and volume for each vehicle is calculated for different carriageway widths.
