Abstract:Evaluating the built environment to determine pedalcyclist riding quality is essential for encouraging travelers to use bicycles as a means of transportation and ensuring rider safety. This research assesses the bike suitability of transportation infrastructure segments using motion and vibration sensors. Data collection was conducted using both iPhone and Android smartphone applications, recording triaxial acceleration data and GPS coordinates along various routes in three locations: Charleston, SC, Columbia, SC, and Lincoln, NE. Smartphones were mounted at the front of the bicycle to ensure an accurate representation of the bike's intrinsic vibrations. Euler's formula was used to reorient the 3-axis acceleration data to the bike’s coordinate system, standardizing the data. Data were analyzed, and pavement anomalies such as cracks and potholes were detected and geocoded. The results were visualized using GIS software, with minor discrepancies observed between Android and iPhone anomaly detection, likely due to variations in GPS accuracy and processing. The comprehensive methodology utilized in this study ensures a thorough evaluation of cycling path quality, contributing to improved urban mobility and infrastructure planning. The study aims to provide valuable insights for policymakers and stakeholders to enhance urban mobility and infrastructure planning, ultimately improving road quality and safety for all users.
