Steer It And Clear It: Effectiveness Of Quick Clearance Legislation, Amy Carol Hamlin
Steer It And Clear It: Effectiveness Of Quick Clearance Legislation, Amy Carol Hamlin
All Theses
Innovative incident management strategies have been sought by transportation professionals to minimize the impacts of incidents on traffic operation and safety. Some current quick clearance strategies such as 'Steer It and Clear It' legislation in South Carolina, which requires driver(s) of involved vehicle(s) in a minor incident to move vehicles promptly from the traveled roadway prior to the arrival of the first responders, can potentially reduce the duration of an incident. The research detailed in this paper endeavored to measure the benefit of the Steer It and Clear It law on a section of I-85 in South Carolina. A simulation …
A Safety Analysis Of Fatigue And Drowsy Driving In The State Of Utah, Hunter T. Young
A Safety Analysis Of Fatigue And Drowsy Driving In The State Of Utah, Hunter T. Young
Theses and Dissertations
Fatigue and drowsy driving in the state of Utah has been a causal factor in thousands of crashes over the years and poses a serious threat to public safety. Consequently, the purpose of this research was to evaluate the impact of drowsy driving in the state, to identify locations where fatigue and drowsy driving may be contributing factors to current crashes, and to identify methods to help mitigate these crashes. A 3-year drowsy driving crash rate spanning the years 2002 – 2004 was used to determine which segments of Utah highway are most prone to drowsy driving crashes. Drowsy driving …
A Prioritization Process For Access Management Implementation In Utah, Kordel T. Braley
A Prioritization Process For Access Management Implementation In Utah, Kordel T. Braley
Theses and Dissertations
Appropriate access management techniques can improve the safety and efficiency of arterial roads. In order to determine which roads can most benefit by the implementation of access management techniques, a prioritization process was developed to recommend various access management treatments such as limiting access points, installing raised medians, and ensuring adequate signal spacing along corridors. To serve as the basis for the performance index, a database was created including identifying features, characteristics, and crash history for 175 arterial road segments on Utah state routes. Stepwise linear regression was applied to the data collected to determine which characteristics of the roads …
