Tillamook Climate Resilience Case Study.pdfTillamook Climate Resilience Case Study ​A series of major storms hit northwestern Oregon in 2015. Tillamook was one of 13 Oregon counties that experienced a state of emergency. Staff from ODOT and the Oregon Health Authority's Public Health Division went to Tillamook to learn how they weathered the storms. This case study shares lessons they learned.
​Safer Than You Think! Revising the Transit Safety Narrative ​This report investigates the impacts that public transportation has on traffic safety (crash risk) and community security (crime risk), and the potential for transit-supportive policies (policies that encourage transit travel and create more transit-oriented communities) to help achieve safety and security goals.
Public transportation is overall a very safe form of travel. It’s passengers have less than a tenth the per-mile crash rates as automobile occupants, and transit-oriented communities have less than a fifth the total (pedestrian, cyclist, automobile and transit passenger) per capita traffic fatality rates as in automobile dependent communities.

Safety of Lithium Nickel Cobalt Aluminum Oxide Battery Packs in Transit Bus Applications ​When considering the use of an lithium nickel cobalt aluminum oxide battery system in a transit bus application, material and structural design is critical to keeping passengers safe. This report by the Mineta National Transit Research Consortium summarizes a variety of tests that were performed to better understand how high-energy cells of this chemistry fail and what materials can be used to manage these failures in a way that increases passenger survivability. ​Oct. 2016
Estimating the Long-Term Effects of MAP-21 on Rural ​Transit Bus Infrastructure This digest focuses on the impacts of MAP-21 on rural transit and on the impact of capital funding levels on the needs of the nation’s rural transit infrastructure.
It summarizes MAP-21's key impacts on rural transit operators and state DOT, analyzes historic funding levels for rural public transportation compared to funding under MAP-21, and projects the future condition of the nation’s rural transit infrastructure.

Transit Website Accessibility ​ This paper by Trillium Solutions discusses the why and how of displaying web-based transit-related information, like timetables, in an accessible way for the vision impaired. It provides easy-to-understand guidance to help transit agencies ensure their websites meet all customers' needs regardless of visual ability. This is a working document. Check back for periodic revisions. ​March 2015
Maximum Theoretical Person Capacity in a 24 Hour Period This recent Oregon DOT thought exercise on theoretical maximum roadway capacity shows that our busiest highways are currently operating at about 2% of theoretical capacity (around 98% underutilized) and hints at the potential for additional transit, TDM and technology investments to increase roadway efficiency. ​Nov. 2013
Transportation & Human Services Coordination Study Information

The Transportation/Human Services Coordination study is a collaborative effort by ODOT and the Oregon Department of Human Services to understand the opportunities and barriers for improved coordination of public transportation and human services in Oregon. 

It identifies the opportunities for and barriers to improved transportation coordination at the state and local levels. The report was prepared by Cogan Owens Cogan, LLC.

Oregon ADA Complementary Paratransit Plans This summary report of key activities and findings provides consultant assistance to local jurisdictions throughout the State of Oregon that are responsible to prepare and adopt Complementary Paratransit Plans as required by the federal Americans with Disabilities Act (ADA). ​April 2011
Veterans' Transportation The Governor's Task Force on Veterans' Services identifies issues facing Oregon veterans and provides recommendations to improve service delivery to those veterans. In every inquiry the task force identified a lack of transportation to and from VA medical appointments as a major barrier to veterans receiving their earned benefits. ​Oct. 2010
Rural Transit in Oregon: Current and Future Needs ​This research identifies the current status and needs for general public transportation in Oregon's rural areas as well as opportunities and barriers to expanding services (e.g., funding, governance issues, and leadership) over a 20-year period. ​Jan. 2010
Assessment of Oregon Coordinated Transportation Plans Association of Oregon Counties, on behalf of ODOT, contracted with Nelson\Nygaard Consulting Associates to review updates to the original Coordinated Public Transit Human Services Transportation Plans (Coordinated Plans) that were prepared in 2009. ​Oct. 2009
Needs, Costs, and Funding Alternatives for Transportation Services for Older Adults and People with Disabilities in Urban and Rural Oregon This report presents an estimate of the demand for and costs of transit for older adults and people with disabilities in Oregon in the year 2030. The focus is on demand response transit. Fixed route transit, particularly in rural areas of the state, is also addressed. ​Oct. 2008
