Road Following is a critical component of blindBike, our assistive biking application for the visually
impaired. This paper talks about the overall blindBike system and goals prominently featuring Road
Following, which is the task of directing the user to follow the right side of the road. This work unlike what
is commonly found for self-driving cars does not depend on lane line markings. 2D computer vision
techniques are explored to solve the problem of Road Following. Statistical techniques including the use of
Gaussian Mixture Models are employed. blindBike is developed as an Android Application and is running
on a smartphone device. Other sensors including Gyroscope and GPS are utilized. Both Urban and suburban
scenarios are tested and results are given. The success and challenges faced by blindBike’s Road Following
module are presented along with future avenues of work.
