Crime is a major issue in today’s society, especially in urban areas. Rapid growth, economic inequality, and increasing populations contribute to various criminal activities. Traditional law enforcement usually responds to incidents after they happen. While this response is necessary, it does not fully address the changing and flexible nature of modern crime, which often shows clear patterns over time and location. There is a need for proactive, data-driven systems that can predict potential crimes and help prevent them. This paper introduces a lightweight and scalable Crime Prediction System. It combines supervised machine learning models with unsupervised clustering techniques to identify areas and times likely to experience crime. The system uses Random Forest, Decision Tree, and Logistic Regression algorithms to classify different types of crime, while K-Means clustering helps locate emerging hotspots. Historical crime data is preprocessed to extract spatio-temporal features for training and evaluation. To make the system user-friendly, we include a web-based dashboard that provides real-time interactive visuals such as heatmaps, time-series graphs, and trend analyses. These visual tools allow law enforcement and policymakers to quickly interpret results, allocate resources effectively, and develop targeted interventions. Our testing revealed that the Random Forest model performed best overall. It achieved close to 85% accuracy and consistently outperformed other classifiers, especially when dealing with complex, imbalanced datasets. However, accuracy wasn’t our only concern. We also included strong security measures. The system includes all the monitoring features to give accurate results, and all the data is secure and save in the database.This is the way which combines machine learning with visual analysis which makes anyone understand easily about the crime details which helps to make more security measures in the areas where the crime rate is shown high .
