Real-Time Stochastic Matching Models for Freight Electronic Marketplace

Principal Investigator: Avinash Unnikrishnan

This grant from the National Science Foundation (NSF) will support research investigating how a real-time marketplace might be constructed to match freight shipments with available carriers. In such a system, freight shippers make a request to the sy ... Read More

Pedestrian Behavior Study to Advance Pedestrian Safety in Smart Transportation Systems Using Innovative LIDAR Sensors

Principal Investigator: Taylor Li

Co-Investigators: Sirisha Kothuri , Xianfeng (Terry) Yang

Pedestrian safety is critical to improving walkability in cities. To that end, NITC researchers have developed a system for collecting pedestrian behavior data using LiDAR sensors. Tested at two intersections in Texas and soon to be tested at another ... Read More

Data-Driven Mobility Strategies for Multimodal Transportation

Principal Investigator: Yao-Jan Wu

Co-Investigators: Xianfeng (Terry) Yang , Sirisha Kothuri

How can we use a variety of data-driven speed management strategies to make transportation safer and more efficient for all modes–whether you’re driving, walking or taking transit? The project was led by Yao Jan Wu, director of the Smart Trans ... Read More

Methodologies to Quantify Transit Performance Metrics at the System-Level

Principal Investigator: Travis Glick

Performance metrics have typically focused at two main scales: a microscopic scale that focuses on specific locations, time-periods, and trips; and, a macroscopic scale that averages metrics over longer times, entire routes, and networks. When applie ... Read More

Understanding Factors Affecting Arterial Reliability Performance Metrics

Principal Investigator: Avinash Unnikrishnan

Co-Investigators: Sirisha Kothuri , Jason Anderson

Researchers from Portland State University (PSU) partnered with Washington County, Oregon to offer data-driven strategies in prioritizing funding for travel time reliability improvements on their urban arterials. The vast majority of existing researc ... Read More

How Technology Can Affect the Demand for Bicycle Transportation: The State of Technology and Projected Applications of Connected Bicycles

Principal Investigator: John MacArthur

The term “connected vehicle (CV)” refers to vehicles equipped with devices, which enable wireless communication between internal and external entities, supporting vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I) and vehicle-to-everything ... Read More

Improving Walkability Through Control Strategies at Signalized Intersections

Principal Investigator: Sirisha Kothuri

Co-Investigator: Christopher Monsere

The goal of signal timing at an intersection should be to separate conflicting movements in time, maximizing safety and efficiency for all users. In many jurisdictions, however, signal timing objectives have traditionally focused on allowing vehicle ... Read More

Online Non-motorized Traffic Count Archive

Principal Investigator: Krista Nordback

Co-Investigator: Kristin Tufte

Robust bicycle and pedestrian data on a national scale would serve numerous purposes. Access to a centralized nonmotorized traffic count archive can open the door for innovation through research, design and planning; provide safety researchers with a ... Read More

Improving Adaptive Response Signal Control Performance: Implications of Non-Invasive Detection and Legacy Timing Practices

Principal Investigator: Sirisha Kothuri

This research will develop a realistic installation guideline that supports the requirements of advance traffic signal controller operations, hybrid detection installations, and non-invasive detection optimization. This guideline shall provide protot ... Read More

Application of Interactive Video Sensing and Management for Pedestrian and Bicycle Safety Studies

Principal Investigator: Wu-chi Feng

Co-Investigators: Christopher Monsere , Miguel Andres Figliozzi

As video data collection and storage technologies become ubiquitous and inexpensive, transportation agencies struggle to process and extract "intelligence"Ã‚Â or useful information from growing libraries of archived video data. In some cases us ... Read More

Modeling and Analyzing the Impact of Advanced Technologies on Livability and Multimodal Transportation Performance Measures in Arterial Corridors

Principal Investigator: Miguel Andres Figliozzi

Co-Investigator: Christopher Monsere

Transit service reliability is important to both passengers and transit agencies. Slow and unreliable transit service may increase transit user costs in the short term and reduce transit mode share and ridership in the long term, which in turn may le ... Read More

Incorporating Pedestrian Considerations into Signal Timing

Principal Investigator: 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 ... Read More
