# What Is Passenger Car Unit

A passenger car unit (PCU) is a measure of a vehicle’s passenger carrying capacity. It is calculated by multiplying the number of occupants by the number of doors. The PCU is used to compare the passenger carrying capacity of different vehicles such as cars buses and trains.

The PCU was developed by the United States Department of Transportation (DOT) in the early 1970s. It is used by the DOT to measure the capacity of passenger vehicles and to compare the capacity of different types of vehicles. The PCU is also used by the Environmental Protection Agency (EPA) to calculate a vehicle’s fuel economy.

The PCU has been criticized by some transportation experts. They argue that the PCU does not take into account the different ways that people use different types of vehicles. For example a car may be used to commute to work while a bus may be used to transport a group of people on a trip.

The PCU is a useful measure of a vehicle’s passenger carrying capacity. It is a simple way to compare the capacity of different types of vehicles. However it is important to keep in mind that the PCU does not take into account the different ways that people use different types of vehicles.
