To address the high deployment costs of single-crime prediction models in policing practice, a multitype crime prediction model integrating spatiotemporal interaction features and spatiotemporal correlation of crimes (MCPM) was constructed. The model’s fundamental functionality encompasses two primary components: spatiotemporal interaction feature extraction and multitype joint learning. The spatiotemporal interaction feature extraction component is designed to capture the key characteristics of environmental features data related to different types of crime, while the multitype joint learning component integrates the spatiotemporal correlations among different types of crime, facilitating the joint optimization of spatiotemporal prediction for multiple crime types. A series of experiments have been conducted on data concerning robbery and burglary crime from Chicago and New York. The following conclusions were reached: The MCPM model demonstrates superior performance in terms of prediction accuracy, with a minimum prediction root mean square error of 0.365 for robbery and 0.288 for burglar and mean absolute error reaches a minimum of 0.277 and 0.226, respectively, indicating a significant margin of improvement over baseline models, with a maximum difference of 31.1% and 36.6%, respectively. Ablation experiments reveal that environmental features data variables contribute the most to the model’s predictions, followed by spatiotemporal correlations between different types of crime. The MCPM model effectively captures the differentiated impact of environmental features data on various crime types, enhancing model performance through the integration of spatiotemporal correlations among crimes.
