How to travel safely based on crime patterns using AWS services

This article presents SafeRoute, a crime-aware navigation system that helps travelers find safer routes by analyzing crime patterns and providing real-time safety alerts.

• Analyzes historical and recent crime data to calculate dynamic risk scores for geographic areas
• Suggests alternative routes that minimize exposure to high-risk zones while maintaining reasonable travel times
• Uses 500-meter grid cells with risk scoring: 70% severity factor, 30% frequency factor
• Classifies areas into four risk levels: Safe, Low, Medium, and High Risk zones
• Allows users to report incidents using natural language, processed by Amazon Bedrock
• Provides in-app alerts, SMS notifications, and emergency contact calling features
• Built on serverless AWS architecture: Lambda, Aurora PostgreSQL with PostGIS, API Gateway, Cognito
• Supports personalized routing based on user crime type preferences
• Encrypts PII at rest and in transit; complies with GDPR and CCPA regulations

SafeRoute demonstrates how AWS services enable municipalities to build scalable, intelligent navigation systems that prioritize resident safety over speed.
