Approximately 7,700 years ago—in a cataclysmic event which the Klamath people retold and passed down for over 300 generations—Mount Mazama erupted, forming Crater Lake in Oregon. With molten rock reaching temperatures of up to 2,200 degrees Fahrenheit, complex chemical reactions ensued. The resulting Mazama ash holds some properties that are similar to those in portland cement.
Today, most construction projects use portland cement, which takes an excessive amount of energy to create. Materials are mined from several different sources and transported, then...Read more
Md Mintu Miah is a Ph.D. student and research assistant in transportation engineering at the University of Texas at Arlington.

Currently, he is working as a Ph.D. student and Graduate Research Assistant of Transportation Engineering at the University of Texas at Arlington, USA under the supervision of Professor Stephen P. Mattingly.
What (or who) has influenced your career path in transportation?
The destitute transportation system of my own country and ample research opportunity in the U.S. have jointly influenced me to study in the field of Transportation Engineering. Initially, I was encouraged by my family, colleagues; later, this dream came...Read more

For a deeper dive into bicycle volume data, watch the May 8 seminar with Tammy Lee and Kristin Tufte: Creating And Using A Publicly Available Multimodal Transportation Data Archive. Also, check out her earlier blog post on motor vehicle traffic volumes.
The weather these past few weeks has been beautiful: sunny, not too hot, not too cold, cherry trees blossoming… the ideal biking weather marred by a less than ideal pandemic.
Are social distancing measures affecting bike trips in Portland, OR? Maybe. Personally? Yes.
First, let’s get a few things out of the way before we provide summary observations:
Analyzing bike data is not as “easy” as evaluating vehicle traffic data: the infrastructure for monitoring bike (and pedestrian) data isn’t anywhere close to how vehicle traffic is monitored. There just aren’t many bicycle count detectors. So if one detector stops working then what little data that was available in the first place became that much littler.

With many transit agencies across the country1 eliminating cash handling at ticket counters and on-board vehicles for obvious health and virus transmission reasons, one may wonder: who will be negatively impacted by this?
Some riders can still use cash at ticket vending machines or at certain retail outlets, but for many, depending on where they live and which parts of the transit system they ride, this will be inconvenient. National data2 show clear disparities3 in access to alternatives to cash (credit and debit accounts) as well as the other tools needed to pay for things electronically (smartphones, cell data plans and internet at...Read more

Now that we are decades into the Age of Information, it's increasingly important to minimize the age of information: that is, to make sure the information we have is the very latest.
In the world of connected vehicle technology, Age of Information (AoI) is a concept that was introduced in 2012 to quantify the “freshness” of knowledge...Read more
Finley Heeb and Maddy Reznick are both undergraduate students in the School of Planning, Public Policy and Management (PPPM) at the University of Oregon. They are both active in the UO's transportation student group, LiveMove, and have worked together as LiveMove's speaker series coordinators for the past two years. Finley was recently featured in a Student Spotlight story in UO news, recounting what they gained from their participation in the summer 2019 Sustainable Bicycle Transportation in Europe study abroad program with faculty Marc Schlossberg and Rebecca Lewis. Maddy was an intern in 2019 at the Los Angeles Regional Collaborative for Climate Action and Sustainability, working with a team of University students to collect and present case study research supporting implementation of a TDM Ordinance in Los Angeles County to the Chief Sustainability Office of LA County.

The University of Utah has a new data visualization service to offer to state DOTs and other agencies. Using Small Starts funding from the National Institute for Transportation and Communities (NITC), researcher Nikola Markovic and his team have developed a suite of visual analysis tools to demonstrate how GPS trajectory data can help accurately model and analyze mobility trends. These data are typically purchased from...Read more
