Research Highlights
Bicycle Detection and Feedback Assessment
Christopher Monsere David Hurwitz , Sirisha Kothuri
Bicycling is increasing in the United States -- the number of trips made by bicycle more than doubled from 1.7 billion trips in 2001 to 4 billion in 2009 (National Household Travel Survey, 2009). With the increase in bicycling rates, there is a critical need for cycling infrastructure, which includes on and off road bicycle lanes and paths, signs, markings, and signals. One of the key links in a bicycle network is signalized crossings of high volume and high speed roadways. At these…

V2X: Bringing Bikes into the Mix
Stephen Fickas
This project focuses on a type of transportation that is currently left out of V2X conversations: bicycling. The project demonstrates how an inexpensive system can add new functionality to existing signal controllers, giving bicyclists an efficient way to cross a controlled intersection. The system proposed and demonstrated integrates three components:
(1) a Bike Connect box that resides near the signal-controller and is connected to it,
(2) an application that runs on a Bike Connect device…
