A Conceptual Framework for Understanding Latent Demand: Accounting for Unrealized Activities and Travel
Latent demand—the activities and travel that are desired but unrealized because of constraints—have been historically examined from the standpoint of understanding the impacts of proposed capacity or service improvements on ...Read More
Getting to Know the Data: Understanding Assumptions, Sensitivities, Uncertainty, and Being "Conservative" While Using ITE's Trip Generation Data in the Land Development Process
Kristina Marie Currans
Many agencies rely on trip generation estimates to evaluate the transportation impacts of land development in urban and suburban areas alike. Over the past decade, substantial attention has been paid ...Read More
Advances in technology such as the advent of autonomous vehicles (AV’s), the rise of E-commerce, and the proliferation of the sharing economy are having profound effects not only on how ...Read More

Although an increasing number of separated bicycle facilities have been appearing across the US over the last few years, the majority of bicyclists are still traveling on roadways shared with ...Read More
As many cities are investing in street improvement or transportation infrastructure upgrade projects to provide better bike access or more complete bike networks, the economic value of bike infrastructure and ...Read More
Patrick Allen Singleton
Why do people travel? We traditionally assume traveling is a means to an end, travel demand is derived (from the demand for activities), and travel time is to be minimized. ...Read More
Planners and policymakers are often faced with the need to make decisions about issues for which there is uncertainty and limited data. For example, transportation planners are now faced with ...Read More
The empirical evaluation of complex decision support systems is often limited to the self-reported satisfaction of the systems’ users.
Such an approach is problematic due to the conflation of the ...Read More
Estimating Reliability Indices and Confidence Intervals for Transit and Traffic at the Corridor Level
Travis B. Glick
As congestion worsens, the importance of rigorous methodologies to estimate travel-time reliability increases. Exploiting fine-granularity transit GPS data, this research proposes a novel method to estimate travel-time percentiles and confidence ...Read More
The number of public bike share systems has been increasing rapidly across the United States over the past five to ten years. To date most academic research around bike share ...Read More
Measuring Stress Levels for Real-World On-Road Cyclists: Do Bicycle Facilities, Intersections and Traffic Levels Affect Cyclists' Stress?
This research effort presents a novel approach to measure cyclists’ stress: real-world, on-road measurements of physiological stress as cyclists travel across different types of bicycle facilities in various traffic volumes. ...Read More
Steven R. Gehrke and Kelly J. Clifton
Land development patterns, urban design, and transportation system features are inextricably linked to pedestrian travel. Accordingly, planners and decision-makers have turned to integrated transportation-land use policies and investments to address ...Read More
The recent City Club report on bicycling provided an opportunity to collect and analyze a number of data sets including the new Hawthorne Bridge data. One question is where Portland ...Read More
The estimation of demand for priced highway lanes is becoming increasingly important to agencies seeking to improve mobility and find alternative revenue sources for the provision of transportation infrastructure.
However, ...Read More
Realistic or Utopian? Coordinating Transit and Land Use to Achieve Equitable Transit-Oriented Development
Equitable transit-oriented development (E-TOD)—the prioritization of social equity as an outcome of TOD implementation—has become a U.S. DOT policy stance, an objective of many other government bodies, and part of ...Read More
Nathan McNeil, Allison Boyce Duncan, and Drew DeVitis
To improve safety and increase transit use, transit agencies and the jurisdictions they serve have to approach transit service as door-to-door not just stop-to-stop.
Walking and bicycling are key modes ...Read More
Christine M. Kendrick
The City of Portland is exploring how distributed "Internet of Things" (IoT) sensor systems can be used to improve the available data that is usable by city engineers, planners, and ...Read More
Dr. Lovell will talk about three projects funded by NASA and the FAA, addressing congestion in the National Airspace System. Dr. Lovell's team developed diffusion-based queuing models of individual airports ...Read More
Development of the Idaho Statewide Travel Demand Model Trip Matrices Using Cell Phone OD Data and Origin Destination Matrix Estimation
As part of the initial phase of development for the Idaho Statewide Travel Demand Model, Parsons Brinckerhoff developed a base year auto and truck trip matrix using AirSage cell phone ...Read More
Population growth and increased accessibility of formerly remote destinations have created new needs for planning mobility to and within recreational areas.
Transportation planners studying recreational travel face unusual travel-demand peaks, ...Read More
Kristina Marie Currans
Understanding changing residential preferences—especially as they are represented within land use and travel demand models—is fundamental to understanding the drivers of future housing, land use and transportation policies. As communities ...Read More
Can Location Value Capture Pay for Transit? Organizational Challenges of Transforming Theory Into Practice
Successful public transit systems increase the value of locations they serve. Capturing this location value to help fund transit is often sensible, but challenging.
This presentation will define location value ...Read More
