Synthesis of Information Related to Highway Practices. Topic 50-08. Emerging Challenges to Tolling on Managed Lanes

A significant component to roadway investment in congested U.S. cities has been managed lanes (i.e., HOV, tolled express lanes and high-occupancy toll (HOT) lanes). In the past decade, over $10 billion in public and private investments have been made in such facilities. However, a number of locations have experienced rising anti-toll sentiment that is threatening both planned and operational projects. As of February 2018, this includes I-77 Charlotte, I-66 Virginia, I-405 Seattle, I-35 Austin, I-635 Dallas, and I-30 Ft. Worth. Tolling manages traffic demand and generate revenue for capital and operational costs. Techniques to manage toll rates, promote benefits to users including carpoolers and transit, address equity and balance competing goals have been challenging to implement and for users to understand. A lack of common performance data such as before-and-after speeds and person and vehicle movement reporting may also play a role in supporting real and perceived benefits by users and policymakers. The impacts to carpoolers on HOT lanes following conversion from HOV-only use is not fully understood. Levels of demand on severely congested corridors may be so large that the toll needed to manage demand may be unsustainable, and the goal of operational management may be forsaken when policymakers limit toll rates and users fail to see benefits. Worse, public attitudes against tolling in any form may be preventing new projects to improve operations from happening. The role that media and social media play in gaining anti-toll traction is not understood. The objective of this synthesis is to identify challenges state DOTs are confronted with related to system management issues and public concerns and acceptance. The synthesis will document strategies and tactics employed, lessons learned, and key success factors.
