In preparing for CAVs, highway agencies will be tasked with identifying and providing appropriate infrastructure elements that will enable or facilitate CAV operations on highways. From an expenditure perspective, the provision of new infrastructure and modification of existing infrastructure is expected to incur a significant amount of capital investment. From a revenue perspective, with increasing CAV operations, the revenues typically earned from vehicle registrations and fuel tax are expected to change due to changing demand for vehicle ownership and amount of travel, respectively. This study is estimating (i) the changes in highway expenditures in an era of CAV operations, (ii) the change in highway revenues that can be expected to arise from CAV operations, the (iii) the changes in highway cost allocation and revenue attribution among the highway users in the era of CAVs.
