The funding and financing of transportation is a complex process requiring joint efforts of federal, state, and local governments. To meet current and future transportation needs, policymakers must constantly assess the mechanism of transportation finance to ensure adequate and sustainable investment. In recent years, depleting state and local budgets and growing capital and maintenance costs related to transportation have been a common challenge. The state of Minnesota is estimated to have billions in unmet transportation needs to keep up with inflation and the increase in transportation demands. This report reviews the funding of public surface transportation systems (including highways, transit and local roads) in Minnesota. We look at how transportation projects have been funded, identify current and future policy issues likely to affect transportation funding, and go over some of the funding options suggested by other researchers. The aim is to encourage better understanding and management of issues related to transportation funding in Minnesota.Item SmarTrAC: A Smartphone Solution for Context-Aware Travel and Activity Capturing(2015-02) Fan, Yingling; Wolfson, Julian; Adomavicius, Gediminas; Vardhan Das, Kirti; Khandelwal, Yash; Kang, JieThe use of mobile phones in collecting travel behavior data has rapidly increased, especially after GPS tracking technology became widely available in commercial smartphones. Existing smartphone-based tools in the field have generally focused on capturing the “when”, “where”, and “how” of travel, i.e., using the smartphone’s automatic sensing functionality to detect travel mode and to collect position and route data. Although locations and modes of transportation derived from sensing data represent important travel behavior information, travel behavior has many other important dimensions—such as trip purpose, travel experience, and travel companionship (i.e., the “why”, “how”, and “who” of travel)—all of which are critical for understanding people’s travel choices. Some of these dimensions may be inferable from pure sensory data, but reliable inference will generally require long-term use data from a very large number of subjects. Other dimensions are simply inaccessible to passive sensing tools. In contrast, traditional travel diary methods and some first-generation smartphone-based travel survey tools enable the collection of multi-dimensional data through high-intensity sampling and qualitative survey techniques. However, these methods are often burdensome to study subjects and impractical for use in a diverse, mobile, and increasingly time-stressed population.
