Research Highlights

Introduction to Scientific Computing for Planners, Engineers, and Scientists

Liming Wang
Building on the successful scientific computing training program offered by the Software Carpentry (http://www.software-carpentry.org/), the proposed course exposes students in science, engineering, and planning to the best practices in scientific computing through hands-on lab sessions and aims to help students tackle the challenge of "drinking from a hose" when dealing with overwhelming amount of data that is increasingly common in these disciplines. Although computing is now an integral part… Read More

Network Effects of Disruptive Traffic Events

Juan Medina Xiaoyue Cathy 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. However, traffic variations due to non recurrent events (e.g. crashes) can be much larger and difficult to predict, making also challenging efforts to measure and forecast their disruptive effects. This project explores a proactive approach to manage non… Read More
