Indiana Highway Cost Allocation Study; A Report on Methodology : Interim Report

Abstract

This interim report presents the proposed methodology for the cost allocation study in Indiana. It describes the highway classification, vehicle classification, cost categories and expenditure items, revenue categories and guiding principles for appropriately assigning the expenditure and revenue among the various highway users. A thickness incremental approach is proposed to allocate new highway construction cost and an integrated approach is proposed to allocate highway rehabilitation and routine maintenance costs. The incremental procedure to allocate structure construction and rehabilitation costs is also presented. In addition, the report provides a detailed discussion of the traffic data collection procedure used in the study.
