🚓 LA Crime Tidal Patterns

STAT4011 Project | Analyzing crime pattern shifts for patrol optimization

🔍 Quick Overview

This part of project analyzed Los Angeles crime data to discover "tidal patterns"—systematic shifts in crime hotspots throughout the day. These patterns help optimize police patrols by predicting where crimes are most likely to occur at different times.

📊 Key Insight

• Daytime: Crime concentrates in downtown & business areas
• Nighttime: Crime moves to transportation hubs & entertainment districts
• Interactive Maps: For each of LA's 21 areas

📈 Our Method

1. Grid-based analysis: Split each area into equal grids
2. Smart risk scoring:

   Risk = Weighted(Crime Severity + Historical Frequency)
   

3. Top-5 selection: For each time period, highlight 5 highest-risk grids

🚀 For Police Use

• Better patrol schedules: Match officers to predicted crime tides
• Resource focus: Concentrate on top 5 high-risk zones per shift
• Early warning: Spot unusual patterns
