Passenger car equivalent

Passenger Car Equivalent (PCE) is a concept used in transportation engineering and traffic studies to quantify the impact of different types of vehicles on road traffic. It allows for the comparison of various vehicle types, such as buses, trucks, and motorcycles, in terms of their effect on road congestion and traffic flow, relative to a standard passenger car. The PCE provides a way to express the number of passenger cars that would produce an equivalent level of traffic impact as a given vehicle type.
