Incorporating Pedestrian Considerations into Signal Timing
Sirisha Kothuri
The role of walking in the development of healthy, livable communities is being increasingly recognized. In urban areas, intersections represent locations where different modes converge, and are often viewed as deterrents to walking. This is due to t ...

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 ...

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 ...

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 ...
