Safety Data Management and Analysis: Addressing the Continuing Education Needs for the Pacific Northwest

PI: Kevin Chang (UI),
Co-Investigators: Cynthia Chen (UW), Robert Perkins (UAF), Ali Hajbabaie (WSU), Shane Brown (OSU)
Dates: 01/16/2015 – 06/15/2016
Led by: University of Idaho (UI) Professor Kevin Chang, this project is the PacTrans Multi-Institution Education Project for 2015-2016.

Safety data collection, management, integration, improvement, and analysis activities are integral to developing a robust data program that leads to more Informed Decision making, better targeted safety investments, and overall improved safety outcomes. Safety data includes crash, roadway, traffic, licensing, and vehicle data. With the increased complexity of the safety data management and analysis activities, and with the limited resources most transportation agencies have, there is a critical need to provide the transportation workforce in the Pacific Northwest with the resources needed to effectively manage and analyze safety data.

Mitigation of Lane Departure Crashes in the Pacific Northwest through Coordinated Outreach

PI: David Hurwitz (OSU),
Co-PI: Linda Boyle (UW), Leila Hajibabai (WSU), Billy Connor (UAF), Ahmed Abdel-Rahim (UI)
Dates: 01/16/2015 – 06/15/2016
Led by: Oregon State University (OSU) Professor David S. Hurwitz, this project is the PacTrans Multi-Institution Outreach Project for 2015-2016.

Approximately 60 percent of fatalities on our nation’s roadways are the result of lane departure crashes. In some cases, the vehicle crossed the centerline and was involved in a head-on crash or opposite direction sideswipe. In others, the vehicle left the roadway to roll over or impact one or more natural or man-made objects, such as trees, utility poles, bridge walls, embankments, or guardrails. A variety of transportation engineering solutions have been proposed to mitigate the occurrence of lane departure crashes including but not limited to: the safety edge, nighttime visibility, rumble strips, retroreflectivity, and pavement lane markings. While these strategies have shown varying degrees of promise in particular contexts, they do no immediately address all of the causal factors inherent in road users (motor vehicle and all-terrain vehicle operators) such as fatigue, operating under the influence, distraction driving, etc. Read More

Regional Map Based Analytical Platform for State-Wide Highway Safety Performance Assessment

PI: Ali Hajbabaie (WSU),
Co-Investigators: Yinhai Wang (UW)
Dates: 01/16/2015 – 06/15/2016

Most traffic crash modeling and safety performance analysis cannot capture impacts of dynamic factors that are often critical for understanding the occurrence mechanism of crashes and are very labor intensive.To address these deficiencies, this proposed research takes advantage of the ongoing DRIVE Net research at the University of Washington to build large-scale safety analysis functions on the data-rich eScience transportation platform. The proposed research has the following objectives: Improve current crash modeling methods; Develop a Safety Performance Index (SPI); Monitor the safety performance of the state highway network on regional map using SPI; Develop a Potential Safety Improvement Index (PSII); Develop safety improvement analysis methods for accident hotspots based on the overlapped SPI and PSII.

Mixed Use Safety on Rural Facilities in the Pacific Northwest

PI: Nathan Belz (UAF),
Co-Investigators: Billy Connor (UAF), Byron Bluehorse (UAF), Kevin Chang (UI), Ahmed Abdel-Rahim (UI), Mostafa Hegazi (UI)
Dates: 01/16/2015 – 06/15/2016

In the United States, formalized facilities and roadway crossings for non-traditional and non-motorized modes do not exist which jeopardizes the safety of these users in many cases. These factors create a pervasive and systemic nationwide safety issue. This research will address the issues associated with providing safe accommodation, limiting the improper use of public rights-of-way, and maintaining mobility, and provide future guidelines for design, education, and enforcement for mixed-use rural facilities. The goal of this project is to: improve safety and minimize the dangers for all transportation mode types while traveling in mixed-use environments on rural facilities through the development and use of engineering and education safety measures.

Unmanned Aircraft System Assessments of Landslide Safety for Transportation Corridors

PI: Keith Cunningham (UAF),
Co-Investigators: Michael Olsen (OSU), Joseph Wartman (UW)
Dates: 01/16/2015 – 06/15/2016

The proposed research addresses Pacific Northwest Transportation Consortium (PACTRANS) research priority of using new data-driven technologies to improve the safety of transportation systems in the Northwest United States. Landslides pose significant threats to the safety of motorists throughout the mountainous terrain of the Pacific Northwest The research will advance landslide safety assessment for transportation corridors by capitalizing on recent advances in unmanned aircraft systems (UAS) and new low-cost Structure from Motion (SfM) photogrammetry techniques. The resulting improved hazard assessment techniques will facilitate cost-effective evaluation of landslide safety across the broadly distributed transportation networks of the Pacific Northwest.
