Passenger load factor is an important parameter for the assessment of the performance of any transport system. Almost all transport systems have high fixed costs, and these costs can only be recovered through selling tickets. [2] Airlines often calculate a load factor at which the airline will break even; this is called the break-even load ...
Crush load on a crowded Indian Railways train. In the context of transport economics and planning, crush load refers to the maximum level of passenger load for a particular vehicle or rail carriage. Crush loads are calculated for the number of passengers per unit area, standing up.
Revenue passenger miles can be considered the basic amount of "production" that an airline creates. The revenue passenger miles can be compared to the available seat miles over an airline's system to determine the overall passenger load factor. [5] These measurements can further be used to measure unit revenues and unit costs. [6]
External factors affect route capacity in different ways. Severely overcrowded highways will reduce the capacity of bus services. Severe snowfalls will reduce the capacity of highways and freeways, and high winds will make landing and departing airports difficult. In many cases route capacity will vary day to day depending on external factors.
Another important factor is the energy needed to build and maintain roads is an important consideration, as is the energy returned on energy invested (EROEI). Between these two factors, roughly 20% must be added to the energy of the fuel consumed, to accurately account for the total energy used. [citation needed]

Passenger-distance is the distance (km or miles) travelled by passengers on transit vehicles; determined by multiplying the number of unlinked passenger trips by the average length of their trips. passenger-kilometre or pkm internationally;
To increase the passenger throughput, many systems can be reconfigured to change the direction of the optimized flow. A common example is a railway or metro station with more than two parallel escalators, where the majority of the escalators can be set to move in one direction. This gives rise to the measure of the peak-flow rather than a ...
