Webinar: State-Wide Pedestrian And Bicycle Miles Traveled: Can We Estimate It?, Krista Nordback Dec 2016

Webinar: State-Wide Pedestrian And Bicycle Miles Traveled: Can We Estimate It?, Krista Nordback

TREC Webinar Series

Heard of Vehicle Miles Traveled (VMT)? Wouldn’t it be great to know the corresponding value for walking and cycling?

This webinar discusses options for estimating the miles people walk and bicycle on the state-wide level, by investigating the practical considerations of trying to compute these values for one study state.

What strategies can be used, and what data sources do these require?

How do these strategies compare?

How do PMT/BMT estimates vary based on data?

Find out what researchers found and what obstacles they encountered when they tried to estimate bicycle and pedestrian miles traveled in the State ...


Pricing And Reliability Enhancements In The San Diego Activity-Based Travel Model, Joel Freedman Dec 2016

Pricing And Reliability Enhancements In The San Diego Activity-Based Travel Model, Joel Freedman

TREC Friday Seminar Series

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, many modeling tools fall short of what is required for robust estimates of demand with respect to toll and managed lanes in two key areas:

  • The value-of-time is often aggregate and not consistently defined throughout the model system, and
  • The reliability of transport infrastructure is rarely taken into account.

This presentation describes an effort which implemented recommendations of the Strategic Highway Research Program C04 and L03\L04 tracks on pricing ...


Webinar: Transit Signal Priority Evaluation And Performance Measures, Miguel Figliozzi Oct 2016

Webinar: Transit Signal Priority Evaluation And Performance Measures, Miguel Figliozzi

TREC Webinar Series

Transit signal priority (TSP) can reduce transit delay at signalized intersections by making phasing adjustments. TSP is a relatively inexpensive tool to provide faster and more reliable transit service. This webinar addresses TSP real-word performance measures as well as data integration and evaluation challenges. Results of the TSP evaluation in an arterial corridor in Portland, Oregon indicate that a timely and effective TSP system requires a high degree of sophistication, monitoring, and maintenance. TSP timing is crucial to reduce transit delay.

Key takeaways include: performance measures, methodology, analysis of early green and red extension pros and cons, novel real-world results.


Pursuing Vision Zero In Seattle – Results Of A Systemic Safety Analysis, Rebecca Sanders Jun 2016

Pursuing Vision Zero In Seattle – Results Of A Systemic Safety Analysis, Rebecca Sanders

TREC Friday Seminar Series

Many cities are considering pursuing Vision Zero to eliminate traffic deaths, but may not know how to move beyond addressing past crash locations toward preventing future crashes. Systemic analysis, which looks at crash patterns to determine common characteristics associated with various types of crashes, shows promise in helping cities to identify problematic locations and treatments in the hopes of preventing future crashes.

This presentation will share results from part of Seattle’s Vision Zero effort – a multi-phased analysis of pedestrian and bicycle crash data aiming to help the City understand both where crashes have occurred and where they are most ...


Connected Vehicles And Rural Road Weather Management, Rhonda Young May 2016

Connected Vehicles And Rural Road Weather Management, Rhonda Young

TREC Friday Seminar Series

Changing weather patterns and increases in extreme weather events has led to the deployment of more weather responsive traffic management strategies. As the transportation system moves towards a connected vehicle environment, questions arise as to how connected vehicle technology can support weather responsive systems. The presentation will discuss the use of connected vehicles in a rural environment as providers of mobile weather data. Two projects will be highlighted - a recently completed research project using passenger vehicle CAN-BUS data as weather surrogates, and the ongoing USDOT CV Pilot Deployment Project in Wyoming.


Measuring What We Value: Using Performance Measures To Achieve Goals, Chris Rall May 2016

Measuring What We Value: Using Performance Measures To Achieve Goals, Chris Rall

TREC Friday Seminar Series

Performance measures are commonly used in transportation planning, but how effectively are public agencies using them, and to what ends?

Metro, ODOT and many cities use performance measures to evaluate investment choices and monitor progress. Drawing from Transportation for America’s report Measuring What We Value, and some of the most cutting edge examples of performance-based planning around the nation, Chris' presentation will step back to consider what makes a performance-based planning approach effective at achieving an agency’s goals.


Webinar: Development Of A Pedestrian Demand Estimation Tool, Kelly Clifton Feb 2016

Webinar: Development Of A Pedestrian Demand Estimation Tool, Kelly Clifton

TREC Webinar Series

Why model pedestrians?

A new predictive tool for estimating pedestrian demand has potential applications for improving walkability. By forecasting the number, location and characteristics of walking trips, this tool allows for policy-sensitive mode shifts away from automobile travel.

There is growing support to improve the quality of the walking environment and make investments to promote pedestrian travel. Despite this interest and need, current forecasting tools, particularly regional travel demand models, often fall short. To address this gap, Oregon Metro and NITC researcher Kelly Clifton worked together to develop this pedestrian demand estimation tool which can allow planners to allocate infrastructure ...
