Behavior-Based Freight Modeling at Metro

Friday, May 5, 2017, 12:00pm to 1:00pm PDT

Chris Johnson and Bud Reiff will present on a behavior-based freight model being used at Oregon Metro. This model will replace Metro’s current truck model with a hybrid freight model that both represents multi-modal freight flows through elements of national and regional supply chains and simulates the movement of individual trucks and shipments on local networks. Model estimation and calibration will also require collection of behavioral data from shippers and receivers representing a wide range of industries, common and contract freight carriers, business that operate non-freight commercial vehicles, warehouse managers, and logistics agents.

Key project objectives:

  • Develop tools to enable a more comprehensive analysis of infrastructure needs and policy choices pertaining to the movements of goods. 
  • Develop more detailed network assignments by truck type, which support regional environmental analysis, as well as local traffic operations and engineering analysis.
  • Develop freight forecasts that are responsive to changes in economic forecasts, changing growth rates among industrial sectors, and changing rates of economic exchange and commodity flows between sectors.
  • Replace trip-...

Network Congestion Effect of E-Hailing Transportation Services

Friday, May 12, 2017, 12:00pm to 1:00pm PDT

E-hailing plays a key role in emerging transportation services such as ridesourcing, ridesharing and taxis, among others. This seminar will present a general economic model to analyze the congestion effect of e-hailing services in a transportation network.

The model can help analyze customers’ choices of different modes, based on their value of time and the charging schemes of different services, as well as the overall impact of the services to network level congestion.

Gentrification and development are changing the face of many Portland neighborhoods. This talk will draw on data from focus groups and participatory mapping research with residents in SE and North Portland neighborhoods. The presentation will share findings on the patterns of movement reported by residents in gentrifying neighborhoods and will offer ideas and perspectives on how to plan for a sustainable future for all Portlanders.

Amy Lubitow is an assistant professor of sociology at Portland State University. Her research interests are environmental sociology, sustainability, environmental justice, social movements, gender and environmental health. Her current projects include critical analyses of urban sustainability, particularly as they relate to bicycle infrastructure; an examination of the transit-dependent population in Portland, including the gendered implications of transit dependency; a study of the influence of scientist-activist...

Webinar: Developing Practical Dynamic Evaluation Methods for Transportation Structures

Thursday, May 25, 2017, 10:00am to 11:00am PDT

Deteriorating transportation infrastructure is constantly in the news. Government agencies at all levels are pursuing methods to monitor structural health, so that they can prioritize repairs. In Oregon, the Cascadia Subduction Zone megathrust earthquake looms as a significant natural hazard for which our transportation network is ill-prepared. The Oregon Department of Transportation (ODOT) estimates that it will take around $2.6 billion over seven years to repair or replace many of the existing bridges in the state’s network to maintain lifeline routes after a Cascadia event. Funding for the scenarios envisioned by ODOT is not forthcoming, and the project described in this webinar is aimed at creating a tool to support visual inspection of bridges for determining the extent of damage.

The work presented in this webinar has evolved out of NITC-funded research and into a feasibility study of relatively simple but effective field methods for transportation structure dynamic evaluation.

The primary driver for the methods under investigation is the advent of robust mobile apps that can process data from...

Annual Metro Regional Trail Count and Why Local Extrapolation Factors Matter

Friday, May 26, 2017, 12:00pm to 1:00pm PDT

Where: Room 204 of the Distance Learning Center Wing of the Urban Center at PSU

Follow this link on the day of the seminar to stream it live.

Metro, Portland's regional governing agency, conducts annual two-hour counts along its regional trail every September. This upcoming fall (2017) will be the 10th year that the counts have been held, which means we at Metro can finally start seeing noticeable, long-lasting trends in the regional trail network. Perhaps more importantly, we are seeing how these data have directly impacted investments in future trail, bicycle, and pedestrian investments.

This seminar will cover the history of the program, details of how it's conducted and why it's conducted that way, how data are used (including an inside look at future iterations of Metro's interactive trail count map), and why creating local extrapolation factors for adjusting to annual traffic is so important.

Geoff Gibson is a former GRA at TREC, a former NITC scholar and a current intern with...

China's Motorization Wave and the Place of Emerging Technologies

Friday, June 2, 2017, 12:00pm to 1:00pm PDT

Where: Room 204 of the Distance Learning Center Wing of the Urban Center at PSU

E-bikes, E-Cars, Carshare, Bikeshare, and Micro-EVs in China have shaken up the traditional motorization pathways that have occurred in developing countries in the past. The combination of emerging vehicle technologies, urban and environmental constraints, and heavy-handed policy make China's motorization processes unique in the world—but how China motorizes has far-reaching impacts based on sheer volume of vehicles and population.

This seminar discusses the results of a six-year NSF CAREER project to explore China's motorization processes, combining behavioral and environmental modeling approaches to assess the impacts of emerging vehicle technologies on motorization and ultimately environmental sustainability. The focus is mostly on emerging lightweight EVs that have surprisingly surpassed all other modes of personal mobility in annual sales and hold great promise across different shared and personal vehicle technologies.
