A Novel Spatio–Temporal Deep Learning Vehicle Turns Detection Scheme Using GPS-Only Data

Abstract

Whether the computer is driving your car or you are, advanced driver assistance systems (ADAS) come into play on all levels, from weather monitoring to safety. These modern-day ADASs use various assisting tools for drivers to keep the journey safe; these sophisticated tools provide early signals of numerous events, such as road conditions, emerging traffic scenarios, and weather warnings. Many urban applications, such as car-sharing and logistics, rely on accurate and up-to-date road map data. Map generation methods use a variety of data sources, including but not limited to global positioning systems (GPS). In this research we propose a GPS-only data trajectory analysis and a novel scheme to convert GPS trajectory data to image-based data to train a custom Convolutional Neural Network (CNN) model. The empirical results with an extensive 5-fold cross-validation show that the proposed scheme identifies turn and not turn with more than 94% recall. It outperforms the existing turn detection schemes on two major frontiers, the required data and the accuracy achieved in detecting different driving behaviors.INDEX TERMS Advance driver assistance systems, CNN, deep learning, GPS data, naturalistic driving, spatio-temporal window analysis, turn detection.

Traffic Sign Recognition for Autonomous Vehicle Using Optimized YOLOv7 and Convolutional Block Attention Module

“…The use of LiDAR and Radar sensors has come up as one of the ways to increase the accuracy of models for TSD in challenging conditions like low lighting [35]. A unique method is described in a study for analyzing Global Positioning System (GPS) trajectory data to detect vehicle turns, which involves converting the data to image-based data, postconversion, a personalized CNN model is designed [36,37].…”

“…The purpose of their investigation was to discover meaningful taxicab movement patterns. In order to create a location recommendation service for empty taxis by clustering the pickup and drop-off sites, work [13] looked at a taxi service's pick-up pattern in same area. In a different work [14], the same author examined the spatial as well as temporal statistics of taxi waiting zones using movement history.…”
