Crowdsourcing The Collection Of Transportation Behavior Data, Christopher Bone, Seth Kenbeek, Ken Kato, Jacob Bartruff Sep 2015

Crowdsourcing The Collection Of Transportation Behavior Data, Christopher Bone, Seth Kenbeek, Ken Kato, Jacob Bartruff

TREC Final Reports

Understanding the travel behaviors of individuals who use public transit is essential for enhancing the performance, sustainability and efficiency of public transportation. Contemporary methods for collecting data on transportation behavior are focused on manual or automated procedures for counting the number of individual passengers entering or exiting transit vehicles. While such methods provide useful data for understanding transit demand throughout a network, they ignore the important details of how passengers travel to and within a network as well as their personal experiences during their commute, all of which can enrich the ability of transit agencies to provide sustainable transportation.

Developing An Oregon Access Management Best Practices Manual, Karen Dixon, Xiang Yi, Lacy Brown, Robert Layton Feb 2013

Developing An Oregon Access Management Best Practices Manual, Karen Dixon, Xiang Yi, Lacy Brown, Robert Layton

TREC Final Reports

This report reviews an Oregon research effort to develop an Oregon Access Management Best Practices Manual. In particular, this research effort develops a resource to help transportation professionals quantify safety and operational effects of various access management strategies, provide measurable criteria to evaluate these access management techniques, and identify data collection practices necessary to successfully perform these assessments. It is the expectation that this manual can be used by engineers, decision makers, and educators to help the transportation community better understand the appropriate application of access management strategies and how to quantify benefits of the various access management options. This …

Wireless Data Collection System For Real-Time Arterial Travel Time Estimates, David S. Kim, J. David Porter, Mario E. Magana, Sejoon Park, Amirali Saeedi

TREC Final Reports

This project pursued several objectives conducive to the implementation and testing of a Bluetooth (BT) based system to collect travel time data, including the deployment of a BT-based travel time data collection system to perform comprehensive testing on all the components. Two different BT-based travel time data collection systems were installed. The first system, composed of two DCUs, was installed on a corridor located in Salem, OR. Extensive testing was done on this system, including the collection of travel time samples. A second system composed of five DCUs was installed along 99W in the city of Tigard, OR. Very limited …
