Rural Bridge Safety: Evaluation of Atypically Large Farm Vehicles
(2018)The Pacific Northwest region has no data on the assessment and recommendations on rural bridge design and safety subjected to Farm Vehicle (FV) loading. The proposed study will determine how different types of FVs with ... -
Safe from Crime at Location-Specific Transit Facilities
(2018)Transit agencies identify two types of exposure to crime: the safety of riders and security. Transit operators have long monitored crime and are cognizant of high incident locations. However, they lack data-driven tools ... -
Safe Main Street Highways Part II: Analyses of Collisions Involving Pedestrians and Bicyclists in Washington State
(2016)This project contributes to the Washington State Strategic Highway Safety Plan, whose goals are to achieve zero road fatality and serious injury by 2030 and to reduce the number of pedestrians and bicyclists involved in ... -
Safe Truck Parking on PacTrans Interstate Corridors: I-5 and I-90
(2018)An inadequate supply of parking spaces for long-haul drivers creates safety issues that may lead to severe or fatal crashes, as tired drivers face the decision of choosing between parking at unsafe locations or continuing ... -
Safety and Operations Assessment of Various Left-Turn Phasing Strategies
(2018)This research evaluated the safety and operational impacts of different left turn movement treatments at signalized intersections. The project (1) compared the safety and operational impacts of protected-only left-turn ... -
Safety Communication Networks: Females in Small Work Crews
(2016)Construction workers experience one of the highest rates of injuries and fatalities in the U.S. Communication is essential for construction safety. Recent research has shown that worker demographics affect the diffusion ... -
Safety Data Management and Analysis: Addressing the Continuing Education Needs for the Pacific Northwest
(2016)Recent advancements in data collection capabilities have allowed transportation-related agencies to collect mountains of safety data. There is an immediate need to find out what types of safety data are being collected, ... -
Safety Data Management and Analysis: Addressing the Continuing Education Needs for the Pacific Northwest (Phase 2)
(2018)The purpose of this two-part project was to respond to gaps in delivering transportation safety education and to develop introductory curriculum materials for both academicians and practitioners. The project objectives ... -
Safety Evaluation of Statewide Off-Highway Vehicle Use in Alaska
(2018)Standard measures of risk and conflict, design guidelines, and informed policies and regulations for off-highway vehicle users (e.g., all-terrain vehicles and snow machines) near and on the traveled way are not well ... -
Safety of Idaho Rural Highways under 129,000-pound Trucks
