Development of Passenger Car Equivalents for Basic Freeway Segments
Passenger car equivalents (PCEs) are used in highway capacity analysis to convert a mixed vehicle flow into an equivalent passenger car flow. This calculation is relevant to capacity and level of service determination, lane requirements, and determining the effect of traffic on highway operations. …

Development of a methodology for measuring delay-based passenger car equivalent for heavy vehicles at signalized intersections
The majority of the current methods for measuring passenger car equivalent (PCE) for heavy vehicles at signalized intersections are based on headway concepts, and are mainly focused on adjusting the ideal saturation flow rate. They do not reflect the total effect of heavy vehicles on delay. The …
