Abstract

This paper: (a) presents a model for predicting the distributions of the gross vehicle weight (GVW) of 5-axle (3-S2) tractor- semitrailers as a function of weight limits for the so-called "complete compliance" condition; (b) converts this complete compliance model into a weight- limit-dependent model of truck load equivalency factors (TLFs), based on the fourth power load rule; (c) examines how different enforcement levels influence TLF; (d) examines how variations in weight split between axles affects TLF; (e) examines the ratio between TLF and payload for 3-S2s, as a function of weight limit, enforcement and weight split; (f) discusses limitations and implications of the model. The model can be used to explore trade off questions relating to the benefits of enforcement, the advantages of better load distribution practices, and their sensitivity to alternative size and weight policies.
