Bus: A bus (archaically also omnibus, multibus, motorbus, autobus) is a road vehicle designed to carry many passengers. Buses can have a capacity as high as 300 passengers.  The most common type of bus is the single-decker rigid bus, with larger loads carried by double-decker and articulated buses, and smaller loads carried by midibuses and minibuses; coaches are used for longer-distance services.  Many types of buses, such as city transit buses and inter-city coaches, charge a fare.  Other types, such as elementary or secondary school buses or shuttle buses within a post-secondary education campus do not charge a fare.  In many jurisdictions, bus drivers require a special licence above and beyond a regular driver's licence.

Crush load: A crush load is a level of passenger loading in a transport vehicle which is so high that passengers are "crushed" against one another.  It represents an extreme form of passenger loading, and normally considered to be representative of a system with serious capacity limitations.  Crush loads result from too many passengers within a vehicle designed for a much smaller number.  Crush loaded trains or buses are so heavily loaded that for most passengers physical contact with several other nearby passengers is impossible to avoid.
