Automatic extraction of relevant road infrastructure using connected vehicle data and deep learning model

This thesis presents a novel approach for extracting road infrastructure information from connected vehicle trajectory data, employing geohashing and image classification techniques. The methodology involves segmenting trajectories using geohash boxes and generating image representations of road segments. These images are then processed using YOLOv5 to accurately classify straight roads and intersections. Experimental results demonstrate a high level of accuracy, with an overall classification accuracy of 95%. Straight roads achieve a 97% F1 score, while intersections achieve a F1 score of 90%. These results validate the effectiveness of the proposed approach in accurately identifying and classifying road segments. The integration of geohashing and image classification techniques offers numerous benefits for road network analysis, traffic management, and autonomous vehicle navigation systems. By extracting road infrastructure information from connected vehicle data, a comprehensive understanding of road networks is achieved, facilitating optimization of traffic flow and infrastructure maintenance. The scalability and adaptability of the approach make it well-suited for large-scale datasets and urban areas. The combination of geohashing and image classification provides a robust framework for extracting valuable insights from connected vehicle data, thereby contributing to the advancement of smart transportation systems. The results emphasize the potential of the proposed approach in enhancing road network analysis, traffic management, and autonomous vehicle navigation, thereby expanding the knowledge in this field and inspiring further research

MobiScout: A Scalable Cloud-Based Driving and Activity Monitoring Platform Featuring an IOS App and a WatchOS Extension

MobiScout is an iOS software that monitors users' driving habits and physiological conditions while on the road. The Mobiscout app was created to provide a low-cost next-generation data collection and analysis solution for naturalistic driving studies. MobiScout collects real-time data, including physiological information from drivers in their normal driving conditions using sensors and cameras on mobile phones, smartwatches, and Bluetooth-enabled OBD equipment. The MobiScout software captures vehicle and driving data, including speed, braking, pulse rate, and acceleration, while the phone's camera captures everything inside and outside the car. Data captured can be streamed to cloud storage in real-time or persisted in local storage in WIFI dead zones. The information gathered will be studied further to better understand typical traffic behavior, performance, surroundings, and driving context among drivers.This is a preprint from Adu-Gyamfi, Kojo Konadu, Karo Ahmadi-Dehrashid, Yaw Okyere Adu-Gyamfi, Pujitha Gunaratne, and Anuj Sharma.
