Webinar: Visual Exploration of Trajectory Data

Tuesday, April 7, 2020, 10:00am PDT
Webinar: Visual Exploration of Trajectory Data
 

OVERVIEW

This webinar will demonstrate the tremendous value of GPS trajectory data in understanding statewide travel patterns and measuring performance. First, Dr. Markovic (U of Utah) will conduct visual exploration of GPS trajectories that capture about 3% of all the trips in Utah. He will briefly discuss the problem of scaling GPS trajectories to the population, and then focus on the use of scaled trajectories in computing origin-destination matrices, vehicle-hours delays, vehicle-miles traveled, and trip-based performance measures. Second, Dr. Franz (CATT Lab) will demonstrate a suite of visual analytics that enables transportation agencies to easily explore terabytes of GPS trajectory data. He will demonstrate different tools and share the experience of 5 state DOTs that are currently using CATT Lab's trajectory data suite.

KEY LEARNING OUTCOMES

  • Trajectory data represents the most complete vehicle-probe data and provides unprecedented opportunity for transportation system analysis.
  • Transportation agencies can easily leverage visual analytics to obtain insights in statewide traffic patterns and performance measures.

Due to the threat of the coronavirus known as COVID-19, we are adapting our event format. We are committed to making decisions that promote the success and well-being of our campus community and growing concerns across Oregon. Like an increasing number of universities nationwide, Portland State is taking additional important steps to respond to the global pandemic. Until further notice, all live events hosted by TREC will be online only.

Friday Transportation Seminars at Portland State University have been a tradition since 2000. You can join us online at 11:30 AM.

THE TOPIC

Prior studies show that transit-oriented developments (TODs) increase property values and raise property tax revenue. Property owners reap economic benefit from TODs and public officials use it as evidence to justify the high cost of rail transit. However, renters, who rely on transit more than homeowners, may have to pay higher rent to live in TODs. The location affordability index at the neighborhood level suggests that renters can also benefit from TOD by saving money on transportation costs. Recent studies at the individual level, however, found...

Webinar: Connected Vehicle System Design for Signalized Arterials

Tuesday, May 12, 2020, 10:00am to 11:00am PDT
Connected Vehicle System Design for Signalized Arterials
 

OVERVIEW

It can be expected that connected vehicles (CVs) systems will soon go beyond testbed and appear in real-world applications. To accommodate a large number of connected vehicles on the roads, traffic signal control systems on signalized arterials would require supports of various components such as roadside infrastructure, vehicle on-board devices, an effective communication network, and optimal control algorithms. In this project, we aim to establish a real-time and adaptive system for supporting the operations of CV-based traffic signal control functions. The proposed system will prioritize the communication needs of different types of CVs and best utilize the capacity of the communication channels. The CV data sensing and acquisition protocol, built on a newly developed concept of Age of Information (AoI), will support the feedback control loop to adjust signal timing plans.

Our multidisciplinary research team, including researchers from transportation engineering and electrical engineering, will carry out the project tasks along four directions that capitalized on the PIs’ expertise:

  1. Data collection and communication, in which the proposed system will be based on the AoI, prioritize the data needs of different types of CVs, and optimize the communication network;
  2. Dynamic traffic signal coordination, which will concurrently facilitate the progression of traffic flows along multiple critical paths; 
  3. Smart...

Webinar: ADA Accessible Trail Improvement with Naturally Occurring, Sustainable Materials

Tuesday, May 19, 2020, 10:00am to 11:00am PDT
 

OVERVIEW

The Americans with Disabilities Act (ADA) provides specific guidelines and requirements that must be met in terms of accessibility.  However, in the case of unpaved trails, the requirements are less defined.  An ADA trail must be firm, stable and slip resistant.  Some compacted aggregate material may meet this definition, but degrade over time and can no longer be ADA compliant.  The benefits of using unpaved surfaces for ADA trails include fit to the natural environment, cost, sustainability and environmental benefits such as increased permeability.  If an unpaved surface can be improved with the use of an additive, more could be used as ADA accessible trails. An earlier NITC study examined The Use of Mt. Mazama Volcanic Ash as Natural Pozzolans for Sustainable Soil and Unpaved Road Improvement. This followup study set out to determine the least amount of portland cement or lime that can be used with this natural pozzolan to create an aggregate binder. This webinar will share the results of that work.

THE TOPIC

As transit agencies modernize their fare payment systems, opportunities to pay with cash are reduced. This speeds boarding and lowers the cost of operations while also creating new sources of ridership data. Arguably, service is improved for riders as well as payment systems could work across modes, creating a more seamless and simplified experience. Still, about 15% of adults in the United States are without a bank account or credit card account and many...

Webinar: Findings From 15 Years Of Travel Surveys At Portland Area Transit-oriented Developments (TODs)

Tuesday, June 2, 2020, 11:00am to 12:00pm PDT
15 years of travel surveys at portland transit oriented development
 

OVERVIEW

Since 2005, Portland State University has periodically surveyed occupants of recently developed  higher-density and mixed-use projects near transit, often referred to as Transit-Oriented Developments (TODs). The general objectives of the surveys were to better understand actual transit use, among other factors, of residents in these buildings. Between 2005 and 2018, the research team surveyed residents of nearly 50 TODs. With funding from Metro and the National Institute for Transportation and Communities, the research team carried out a two-pronged study drawing on this wealth of data. First, we explore geographic differences within the Portland region in terms of travel behavior and attitudes of TOD residents, including differences between TODs within the city of Portland, in eastside suburbs, and in westside suburbs. Second, we conducted a second wave of surveys for select TODs to understand if travel behavior or attitudes changed over time, particularly as neighborhoods surrounding the buildings were built up. In this webinar, we will present select findings from both aspects of the study.

KEY LEARNING OUTCOMES

  • Learn about the concept and goal of transit-oriented development 
  • Understand who lives in TODs, and how they get around 
  • Learn about the potential impact of TOD on travel behavior, including variations by location and over time.
