Real-Time Stochastic Matching Models for Freight Electronic Marketplace

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

Data-Driven Mobility Strategies for Multi-Modal Transportation

Yao-Jan Wu
Xianfeng Yang , Sirisha Kothuri
By using various modes (e.g., walking, cycling, automobile, public transit, etc.), multi-modal transportation systems are effective in increasing people’s travel flexibility and reducing congestion. Hence, it is critical to understand how roadway s ... Read More

Connected Streetcar Project

Kristin Tufte
Larry Head , John MacArthur
This project will create a foundation for deploying connected vehicle infrastructure and facilitating connected vehicle research for the NITC UTC. Connected Vehicle (CV) technology and the associated data has the potential to help us better understan ... Read More

Understanding Factors Affecting Arterial Reliability Performance Metrics

Avinash Unnikrishnan
Sirisha Kothuri , Jason Anderson
With worsening congestion, travel time reliability is increasingly becoming as critical as average travel times in affecting travel choices. This research project will first study the data requirements for existing travel time reliability metrics bei ... Read More

Creating Livable Communities through Connecting Vehicles to Pedestrians and Cyclists

John MacArthur
Safety of pedestrians and bicyclists is a significant problem in U.S., with 4,743 fatalities and 76,000 injuries of pedestrians and 726 fatalities and 49,000 injuries of bicyclists in 2012 (NHSTA 2014a & b). Establishing and creating livable communit ... Read More

Improving Walkability Through Control Strategies at Signalized Intersections

Sirisha Kothuri
Christopher Monsere , Edward Smaglik
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

Krista Nordback
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 ... Read More

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 ... Read More

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

Wu-chi Feng
Christopher Monsere , Miguel Figliozzi
As video data collection and storage technologies become ubiquitous and inexpensive, transportation agencies struggle to process and extract "intelligence" 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

Miguel Figliozzi
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

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

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

Operational Guidance for Bicycle-Specific Traffic Signals

Christopher Monsere
Miguel 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
