Performance-based oversize and overweight permitting system

This paper presents a conceptual framework for a federally supervised, state-administered, performance-based oversize and overweight permit program for the operation of heavier and larger vehicles on the public highways. The structure of the permitting system is based on experiences and practices in implementing performance-based systems in Australia, Canada, New Zealand, and the United States. Conceptually, the framework consists of three main interrelated components: administrative, enforcement, and evaluation systems. The administrative system comprises several elements directed at establishing the requirements, standards, and administration of the permitting system. The enforcement system includes regulations, special conditions, education or communication to the industry, effective fines or penalties for violators, and adjudication. The enforcement system will periodically generate records indicating carrier compliance or noncompliance with the terms and conditions of permits and the frequency of these events. The evaluation system defines the data and processes to ensure that the permitting system is continuously evaluated. The results of the evaluation are necessary for revising the performance standards, limits, and conditions for the permitted vehicles. The challenge is enforcement of the performance-based, oversize and overweight permitting system. Periodic reassessments of permitted vehicles in addition to continued roadside enforcement of operating conditions are recommended.
