A new NITC project has developed a robust pedestrian demand estimation tool, the first of its kind in the country.

Using the tool, planners can predict pedestrian trips with spatial acuity.

The research was completed in partnership with Oregon Metro, and will allow Metro to allocate infrastructure based on pedestrian demand in the Portland, Oregon metropolitan area.

In a previous project completed last year as part of the same partnership, the lead investigator, Kelly Clifton, developed a way to collect data about the pedestrian environment on a small, neighborhood scale that made sense for walk trips. For more about how that works, click here to read our news coverage of that project. 

Following the initial project, the next step was to take that micro-level pedestrian data and use it to predict destination choice. For every walk trip generated by the model in the first project, this tool matches it to a likely destination based on traveler characteristics and environmental attributes.

Founded to collect the transportation data created by agencies across the region, Portal had done its job almost too well. The data archive, a program of TREC, had taken in more data than it could make available.

Portal started in 2004 with just one data source: Oregon freeway loop detectors. Over the years, it grew into a truly multimodal data archive, incorporating transit data, traffic signal data, bicycle and pedestrian counts – eight data sources spanning two states and multiple agencies.

Its budget didn’t grow proportionately, however, leaving Portal less able to make use of the data it collected. Portal’s $125,000 in regional transportation money just kept the system running, said Portal director Kristin Tufte. “It was enough money to keep the lights on,” she said.

Given Portal’s potential to help agencies improve operations and researchers to address systemwide issues, that wasn’t enough. The information had to be accessible to make a difference.

A boost in support for Portal is helping to make that possible. With a grant from the Institute for Sustainable Solutions at Portland State, TREC hired a Portal programmer this year to present the data visually.

Though key to Portal’s...

DASH is the next generation activity based model being developed by the Metro Research Center. Upon completion, it will be one of the most advanced in the nation. This model will be used extensively in estimating the activity and travel response of individuals to policies and infrastructure investments. Compared to past models, it will include enhanced consideration of the socio-economic roles of individuals, discrete temporal dynamics, and intra-household dependencies.

He manages the technical elements of all programs related to travel and landuse forecasting: including data collection, model development, and model applications. In addition, Mr. Walker currently serves as the chair of the Oregon Modeling Steering Committee – a statewide entity formed to promote collaboration between Oregon modeling agencies with regard to model development activities. As a recipient of a BS degree in civil engineering from Montana State University, he has been a member of the modeling...
