From AJ: The State of Oregon, the long-time US leader in transport finance, has posted a series of Tolling White Papers (about 2/3 down the page) Topics include:
Air Quality/Greenhouse Gas Emissions: Is pricing the best tool for reducing transportation-related greenhouse gas emissions?
Geographic and Situational Limits: Are there places in Oregon where tolling should not be considered? Are there conditions which should be defined and met for a tolling or pricing project to be successful?
Demand Projection Sufficiency: Are current travel demand models sufficient to effectively evaluate toll projects?
Economic Evaluation of Improved Reliability: How do we define and measure travel time reliability for personal and commercial travel, across a broad application of congestion pricing?
Assessing the Economic Effects of Congestion Pricing: How does “pricing” urban highway networks affect transportation, people and businesses?
Economic Comparison of Alternatives: How do you determine if tolling is a better alternative than other non-tolled options such as adding capacity or transit services?
Truck-Only Toll Lanes: Are truck only toll lanes a viable option for Oregon?
