The ultimate test of theory is comparison with reality. The procurement of reliable and reproducible traffic data is relatively difficult since little control can be exercised over the character and level of the input to the load carrying system without invalidating the genuineness of the input. There is then a continuing need to compare the commonly used load-loss relations with observations made under a variety of trunking configurations and load characteristics. D a t a are presented here and compared with loss theory in three trunking areas: highusage groups; full (nonalternate routed) groups; and final groups. The various findings are summarized at the end of the paper.
