Halation or irradiation makes guide sign fonts difficult to read. Missing the necessary guide sign information causes anxiety and confusion to drivers, and hence may lead to crashes. In order to avoid or mitigate the situation a newer font, Clearview, is used to provide better readability at long distances. In a similar context the lack of brightness in sheeting material for warning signs reduces conspicuity of sings. Installation of fluorescent yellow sheeting has been done to provide signs with more noticeable and brighter materials. This observational before and after study is an evaluation of the safety and economic benefits of …

A Framework To Predict High Risk Roadways For Pedestrians In Tennessee, Zane Hunter Pannell
Masters Theses
Pedestrians and bicyclists are a class of vulnerable road users that are often over-represented in incapacitating injury or fatal crash statistics. Because non-motorized trips are vital to many urban and rural residents for utility or recreation and exercise, it is essential to identify safety deficiencies in our existing transportation infrastructure to address rising injuries and fatalities among this group of road users. As the economy continues to struggle and fuel prices remain high, many cities and rural transportation agencies are seeing large increases in bicycling, walking, and transit ridership. While passenger car fatalities have shown sharp declines in the last …

Spatial Factors Impacting Non-Motorized Exposures And Crash Risks, Farhad Abasahl
Masters Theses
This research investigates spatial factors, that impact non-motorized exposures and crashes, and examines the relationship between exposure at signalized intersections and crash frequencies involving pedestrians and bicycles at a census tract level. The four Michigan cities of Ann Arbor, East Lansing, Flint and Grand Rapids are examined. After completing an extensive literature review to provide a list of required data, 92 intersections are selected from the four cities to collect pedestrian and bicyclist counts. Five-year crash records, special attractions, non-motorized facilities and transportation infrastructure data for the four cities are gathered for the four cities. This data are later mapped …
