Increasing Ridership of Santa Fe Trails

This project evaluated methods that aimed to increase ridership of the Santa Fe Trails public transportation system in Santa Fe, NM. Problems in service were revealed through the analysis of surveys given to bus riders and non-riders. Solutions to these problems included a feeder system for people outside walking distance to the bus, riding information on new signs, and a mobile application for using the Trails. These solutions have a high chance of being implemented in the near future

Real-Time Indoor Localization using Visual and Inertial Odometry

This project encompassed the design of a mobile, real-time localization device for use in an indoor environment. A system was designed and constructed using visual and inertial odometry methods to meet the project requirements. Stereoscopic image features were detected through a C++ Sobel filter implementation and matched. An inertial measurement unit (IMU) provided raw acceleration and rotation coordinates which were transformed into a global frame of reference. A Kalman filter produced motion approximations from the input data and transmitted the Kalman position state coordinates via a radio transceiver to a remote base station. This station used a graphical user interface to map the incoming coordinates
