  Citation × Citation Citation Abstract Copy Title: Dynamic Assignment Models and their Application in the Portland Metro Region Author: Bosa, Peter G. Year: 2017 Metro's Research and Modeling Services Program is responsible for the development, maintenance, and application of travel demand models for application in long-range planning efforts in the Portland metropolitan region. Representation of traffic—both vehicular and transit—plays an integral role in the travel demand modeling process. Complex software is required to assign vehicles and transit users to transportation networks to determine viable options available to travelers, costs associated with those options, and sets of routes by which travelers might navigate their trips. Metro's current static assignment model has traditionally sufficed for use with Metro's four-step travel demand model. However, static assignments have well-documented limitations that preclude the ability of the analyst to answer complex policy questions, especially those related to greenhouse gas emissions, congestion, and transportation network reliability. In addition, static assignments cannot fulfill a need for small-duration travel time increments required by the next generation activity-based models. The shortcomings of the static assignment necessitates Metro’s development and application of regional dynamic traffic assignment (DTA) models. The resolution of these models allows for continuous modeling of traffic over an analysis period, which allows the analyst to capture temporally-based traffic events such as the building and dissipation of queues, measurement of the duration of congestion, and high fidelity speed profiles for use in emissions analysis. This presentation will focus on why Metro has developed a DTA, how DTA compares with other models—specifically macro-scale static assignments and micro-simulations—and how DTA has been applied in Metro's modeling process.

• 4. [Article] Annual Metro Regional Trail Count and Why Local Extrapolation Factors Matter

  Citation × Citation Citation Abstract Copy Title: Annual Metro Regional Trail Count and Why Local Extrapolation Factors Matter Author: Gibson, Geoff Year: 2017 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 projects. 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.
