Abstract:

This project demonstrates how an inexpensive system (hardware and software) can add new functionality to existing signal controllers, giving bicyclists an efficient way to cross a controlled intersection. The system 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 (currently an iPhone) and requests a green light at the correct approach-distance, and (3) a cloud-based publish/subscribe (pub/sub) component that handles cellular-communication between phone app and box. One stumbling block for the project was a means to obtain reliable GPS data to compute distance while walking, biking and standing still (being idle). We report on our evaluation of 4 methods: raw GPS, averaged GPS, line of best fit and speed. We found that a combination of methods was most effective and describe that combination and its results. The final system was put into place and tested with 120 separate rides. We report on our results and potential future paths to take the research.
