    An Analysis of the Public and Private Transportation Costs of a Rural Agricultural Area
    (1992-01) Fruin, Jerry; Halbach, Dan
    The objective of this study was to develop a computer simulation model to determine the types and amounts of transportation costs in a rural agricultural area under the conditions existing in 1989. Then different assumptions about the road infrastructure could be made and corresponding changes made to the model. The simulation model would be rerun for each set of assumptions and the results analyzed to determine how the different costs change with different infrastructures. This unique approach considers both the public costs such as the maintenance and construction costs paid by tax payers and user fees and the private costs, which are the costs incurred by individuals and firms operating vehicles over the road systems as they travel or move goods.

    Application of a Rural Safety Policy Improvement Index (RSPII) Framework
    (University of Minnesota Center for Transportation Studies, 2010-06) Knapp, Keith K.; Utecht, Brad
    Six legislatively-based safety improvement measures (LSIMs) were proposed for evaluation within a rural safety policy improvement index (RSPII) framework during Phase I of this project. This report documents the step-by- step application of the RSPII framework and its rural roadway crash fatality reduction results for these LSIMs. Several approaches to the framework application were completed for each LSIM and the results compared. It was estimated (based on the selection of one framework outcome for each LSIM) that rural roadway crash fatalities could be reduced by 209 from the primary enforcement of seat belt use, 299 from universal motorcycle helmet use, 322 from the regular application of sobriety checkpoints, 120 from graduated driver licensing program upgrades, 268 from the mandatory ignition interlock installation, and 699 from automated speed enforcement. These estimates cannot be summed, however, because the fatalities impacted by these LSIMs sometimes overlap. The assumptions and generalizations required to overcome challenges to the RSPII framework application will also have an impact on its results. Additional LSIM research is suggested and it is recommended that the estimates in this report be used as a starting point for rural roadway safety discussions and the completion of more accurate individual state RSPII framework applications.

    In-Vehicle Dynamic Curve-Speed Warnings at High-Risk Rural Curves
    (Minnesota Department of Transportation, 2018-03) Davis, Brian; Morris, Nichole L.; Achtemeier, Jacob D.; Patzer, Brady
    Lane-departure crashes at horizontal curves represent a significant portion of fatal crashes on rural Minnesota roads. Because of this, solutions are needed to aid drivers in identifying upcoming curves and inform them of a safe speed at which they should navigate the curve. One method for achieving this that avoids costly infrastructure-based methods is to use in-vehicle technology to display dynamic curve-speed warnings to the driver. Such a system would consist of a device located in the vehicle capable of providing a visual and auditory warning to the driver when approaching a potentially hazardous curve at an unsafe speed. This project seeks to determine the feasibility of in-vehicle dynamic curve-speed warnings as deployed on a smartphone app. The system was designed to maximize safety and efficacy to ensure that system warnings are appropriate, timely, and non-distracting to the driver. The developed system was designed and implemented based on the results of a literature survey and a usability study. The developed system was evaluated by 24 Minnesota drivers in a controlled pilot study at the Minnesota Highway Safety and Research Center in St. Cloud, Minnesota. The results of the pilot study showed that, overall, the pilot study participants liked the system and found it useful. Analysis of quantitative driver behavior metrics showed that when receiving appropriately placed warnings, drivers navigated horizontal curves 8-10% slower than when not using the system. These findings show that such a curve-speed warning system would be useful, effective, and safe for Minnesota drivers.
