Abstract
Popular navigation applications such as Google Maps and Apple Maps provide distance-based or travel time-based alternative routes with no real-time risk scoring. There is a need for a real-time navigation system that can provide the data-driven decision on the safest path or route. By leveraging data from a diverse range of historical and real-time sources, this study successfully developed a user interface for a navigation tool or application that offers informed and data-driven decisions regarding the safest navigation options. The interface considers multiple scoring factors, including safety, distance, travel time, and an overall scoring metric. This study made a distinctive and valuable contribution by designing and implementing a robust safe navigation tool driven by artificial intelligence. Unlike existing navigation tools that offer multiple uninformed route options, this tool provides users with an informed decision on the safest route. By leveraging advanced AI algorithms and integrating various data sources, this navigation tool enhances the accuracy and reliability of route selection, thereby improving overall road safety and ensuring users can make informed decisions for their journeys.
Project Highlights
- This study used Google Directions API and Open Route Services (ORS) API to explore the route-finding algorithms with the inclusion of safety risk scores of different routes.
- Incorporated advanced AI algorithms and various data sources to develop a robust navigation tool that significantly enhances the accuracy and reliability of route selection, ultimately improving overall road safety and enabling users to make well-informed decisions for their journeys.
- Highlights the potential of AI-driven technologies to revolutionize the field of navigation and enhance road user safety.
