This report documents the results of the Highway Performance Monitoring System (HPMS) Truck Weight Case Study which was conducted from the fall of 1980 to the fall of 1981. The report provides information on the seasonal, daily, and hourly variation in truck weights on rural and urban functional systems. This information plays a vital part in pavement design, cost allocation, the determination of highway needs, and, in combination with other data sources, can be used to determine the required thickness of new pavements or overlays to existing pavement, calculate ton-miles of freight, assess the cost responsibility of various users, evaluate pavement deterioration, and estimate energy consumption.
This case
study was primarily designed to measure the variation in truck operating
weights within functional systems by season of the year, weekday/weekend,
and hour of day. The following functions were covered in both rural and
urban areas: interstate (plus other freeways and expressways in urban
areas); other principal arterials; and minor arterials/collectors.
Six states
were selected to participate in this study: Arkansas, Florida, Iowa, Nevada,
Oregon, and Wisconsin. Each state selected weighing sites to achieve a
representative distribution of sites by functional class. Data were collected
at both static and weigh-in-motion (WIM) scales in accordance with the
instructions included in "Highway Performance Monitoring System Case
Study Procedural Manual - Truck Weight" (January 1980).
