Integrating Real-Time Environmental Data and User Proficiency for Intelligent Trail Recommendation: A Thematic Review

Adventure tourism has experienced significant growth in recent years, with outdoor recreational activities such as hiking and mountaineering attracting millions of participants worldwide. However, the increasing popularity of trail-based activities has raised concerns about participant safety, environmental sustainability, and the need for personalized experiences that match individual capabilities. Traditional trail recommendation systems often rely on static information and fail to account for dynamic environmental conditions or real-time assessment of user proficiency levels. This paper proposes a thematic review for intelligent trail recommendation that integrates real-time environmental data streams with continuous user proficiency assessment to deliver safe, personalized, and context-aware trail suggestions. The proposed of this study leverages machine learning algorithms, Internet of Things (IoT) sensors, and semantic data models to process multi-dimensional data including weather conditions, terrain characteristics, trail difficulty metrics, and physiological indicators of user capability. We present a thematic review of existing approaches in trail recommendation systems, environmental data integration, user proficiency modeling, and safety-aware computing. This study reveals that while existing systems address individual components, there is a critical gap in holistic frameworks that seamlessly integrate environmental dynamics with user-specific capabilities. The proposed approach contributes to the advancement of intelligent tourism systems by providing a foundation for safer, more personalized outdoor recreational experiences that adapt to changing conditions and individual user profiles.
