Blockchain Traffic Event Validation and Trust Verification Using IOT

Abstract

Sharing traffic information on the vehicular network can help in the implementation of intelligent traffic management, such as car accident warnings, road construction notices, and driver route changes to reduce traffic congestion earlier. If the exposed traffic incident is incorrect, the driving route will be misleading, and the driving response may be in danger. The blockchain ensures the correctness of data and tampers resistance in the consensus mechanism, which can solve such similar problems. The traffic data are collected through the roadside units, and the passing vehicles will verify the correctness when receiving the event notification. We employ data collection, preprocessing, sentiment analysis, geospatial analysis, and machine learning techniques to automatically identify and categorize traffic events, such as accidents, congestion, or road closures, based on information shared by users on various social media platforms. The framework aims to provide accurate and timely insights into traffic conditions, enabling better urban planning and incident response.
