Item Aggregating VMT within Predefined Geographic Zones by Cellular Assignment: A Non-GPS-Based Approach to Mileage- Based Road Use Charging(Intelligent Transportation Systems Institute, Center for Transportation Studies, University of Minnesota, 2012-08) Davis, Brian; Donath, MaxCurrently, most of the costs associated with operating and maintaining the roadway infrastructure are paid for by revenue collected from the motor fuel use tax. As fuel efficiency and the use of alternative fuel vehicles increases, alternatives to this funding method must be considered. One such alternative is to assess mileage based user fees (MBUF) based on the vehicle miles traveled (VMT) aggregated within the predetermined geographic areas, or travel zones, in which the VMT is generated. Most of the systems capable of this use Global Positioning Systems (GPS). However, GPS has issues with public perception, commonly associated with unwanted monitoring or tracking and is thus considered an invasion of privacy. The method proposed here utilizes cellular assignment, which is capable of determining a vehicle’s current travel zone, but is incapable of determining a vehicle’s precise location, thus better preserving user privacy. This is accomplished with a k-nearest neighbors (KNN) machine learning algorithm focused on the boundary of such travel zones. The work described here focuses on the design and evaluation of algorithms and methods that when combined, would enable such a system. The primary experiment performed evaluates the accuracy of the algorithm at sample boundaries in and around the commercial business district of Minneapolis, Minnesota. The results show that with the training data available, the algorithm can correctly detect when a vehicle crosses a boundary to within ±2 city blocks, or roughly ±200 meters, and is thus capable of assigning the VMT to the appropriate zone. The findings imply that a cellular-based VMT system may successfully aggregate VMT by predetermined geographic travel zones without infringing on the drivers’ privacy.Item Potential Benefits of Mileage-Based User Fees to the Freight Industry and Industry Concerns(Minnesota Department of Transportation, 2012-08) Robinson, Ferrol O.; Coyle, David D.; McCullough, Gerard J.The concept of funding surface transportation infrastructure through fees charged on miles driven has been receiving growing attention from transportation professionals and researchers in recent years. Highway funding in the United States has traditionally been done through user fees, most notably motor vehicle fuel taxes. However, there are growing concerns among some policymakers that fuel taxes no longer serve as an adequate, sustainable, efficient, nor equitable user fee. Recognizing the problems that arise when surface transportation is funded through motor fuel taxes, several entities, both in the United States and abroad, have conducted pilot projects or have implemented mileage-based fees. Several of these have been specifically designed for heavy trucks. There are two major concerns related to truck travel: (1) heavy trucks consume a great deal of roadway capacity due to their size, operating characteristics, and annual miles traveled; and (2) roadway wear and tear caused by the combination of truck mileage and heavy loads is significant and disproportionate to the number of trucks on the road. The concept of mileage-based user fees has seen increasing support from a number of groups in recent years; however, it faces opposition from many in the general public, and in particular from the trucking industry – which largely objects to this approach to funding transportation. This paper is part of a larger effort exploring the benefits to the freight industry of mileage-based user fees, while highlighting industry concerns over its implementation.
