Transit Website Accessibility

March 2015 (ongoing)

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.

Maximum Theoretical Person Capacity in a 24 Hour Period

November 2013

How can we increase the passenger carrying capacity of our roadways? Imagine filling all the empty vehicle seats on the road with people. Then, suppose we fully utilize the roadway 24 hours a day and replace all personal vehicles and freight carriers with buses full of people. How many more people could we move than our busiest highways are moving now? 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.

Transportation & Human Services Coordination Study Information

July 2013

The Transportation/Human Services Coordination study builds on prior work on transportation-human services coordination in the state and will identify what has changed in terms of coordination since 2000. It will assess prior work to identify what has worked well and what barriers have prevented implementation of recommendations for improved coordination. The Oregon Department of Transportation's Public Transit Division contracted with the Association of Oregon Counties (AOC) to manage the study. AOC hired Cogan Owens Cogan to conduct the study. Policy Steering and Technical Advisory Committees were established to provide guidance.
