This project is a follow up to a highly successful previous NITC project and subsequent nationally distributed book, called “Rethinking Streets: An Evidence Based Guide to 25 Street Transformations. The success of the first book demonstrates a need ... Read More

Network effects of disruptive traffic events

Juan Medina
Xiaoyue Liu
Current traffic management strategies are based on expected conditions caused by recurring congestion (e.g. by time of day, day of week), and can be very effective when provisions are also given for reasonable variations from such expectations. Howev ... Read More

Understanding Factors Affecting Arterial Reliability Performance Metrics

Avinash Unnikrishnan
Sirisha Kothuri
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

Planning in gateway and amenity communities: understanding unique challenges associated with transportation, mobility, and access to opportunity

Danya Rumore
