Operational Guidance for Bicycle-Specific Traffic Signals

Christopher Monsere
Miguel Andres Figliozzi
The research consisted of two phases: 1) a synthesis of practice and 2) and analysis of cyclist performance characteristics. The synthesis of current practice reviewed the literature, current engineering design and operational guidance documents, and ... Read More

Application of Smart Phone Truck Data for Freight Performance Measures and Transportation Planning

Miguel Andres Figliozzi
Oregon is one of the few states that currently charge a commercial truck weight-mile tax (WMT). The Oregon Department of Transportation (ODOT) has developed a data-collection system – Truck Road Use Electronics (TRUE) – to simplify WMT collection ... Read More

Integrated Multimodal Transportation, Air Quality, and Livability Corridor Study Phase II

Miguel Andres Figliozzi
Christopher Monsere , Linda George
The Sydney Coordinated Adaptive Traffic System (SCATS) is used to mitigate traffic congestion along urban arterial corridors. Although there has been research on SCATS’ performance, this report combines three different areas of research about SCATS ... Read More

Improved Pedestrian Safety at Signalized Intersections Operating the Flashing Yellow Arrow

David Hurwitz
Christopher Monsere
In some jurisdictions, protected left-turn phasing has been replaced with the flashing yellow arrow (FYA) for protected/permissive left turns (PPLTs) to reduce delay. However, it is important to have a thorough understanding of the conflict between p ... Read More

Refining GreenSTEP: Impacts of Vehicle Technologies and ITS/Operational Improvements on Travel Speed and Fuel Consumption Curves

Kelly Clifton
Alex Bigazzi
This report describes analysis undertaken to establish a method for incorporating traffic operations and ITS strategies into the GreenSTEP model. We first discuss operations impacts on fuel economy and delay from the literature. Then, an investigatio ... Read More

Multimodal Data at Signalized Intersections: Strategies for Archiving Existing and New Data Streams to Support Operations and Planning

Christopher Monsere
Kristin Tufte
There is a growing interest in arterial system management due to the increasing amount of travel on arterials and a growing emphasis on multimodal transportation. The benefits of archiving arterial-related data are numerous. This research report desc ... Read More

The Sydney Coordinated Adaptive Traffic System (SCATS) is used to mitigate traffic congestion along urban arterial corridors. Although there has been research on SCATS’ performance, this report combines three different areas of research about SCAT ... Read More

Value of Reliability

Miguel Andres Figliozzi
David Levinson
Travel-time variability is a noteworthy factor in network performance. It measures the temporal uncertainty experienced by users in their movement between any two nodes in a network. The importance of the time variance depends on the penalties incurr ... Read More

Value of Travel Time Reliability: Commuters' Route Choice Behavior and Study of Tradeoffs - Phase 2

Miguel Andres Figliozzi
David Levinson , Kathleen Harder

The issue of travel time reliability is becoming more critical for the movement of people and freight. In order to examine issues related to the value of travel time reliability, we plan to test drivers' preferences for alternate commuter r ... Read More

Exploratory Methods for Truck Re-identification in a Statewide Network Based on Axle Weight and Axle Spacing Data to Enhance Freight Metrics: Phase 2

Christopher Monsere
Mecit Cetin , Andrew Nichols
Vehicle re-identification methods can be used to anonymously match vehicles crossing two different locations based on vehicle attribute data. This research builds upon a previous study and investigates different methods for solving the re-identificat ... Read More

Case Study Evaluation of Dynamic Traffic Assignment Tools

John Gliebe
DEVELOPMENT AND SENSITIVITY TESTING OF ALTERNATIVE MOBILITY METRICS: The Oregon Highway Plan’s (OHP) mobility policies guide various planning and programming activities of the Oregon Department of Transportation (ODOT). Among these activities are O ... Read More

Exploiting a Next Generation ITS Data Warehouse for Improved System Performance and Congestion Monitoring

Kristin Tufte
