Objectives: Public transportation systems experience dynamic changes over time to accommodate growing cities, yet evaluations of their impact on crime often focus on shorter, static periods. This study examines the long-term relationship between light rail expansion and crime, using a 20-year observation period in Charlotte, NC. We analyze changes in crime patterns near original, expanded, and planned light rail station locations. Methods: We conducted a quasi-experimental program evaluation of the opening of light rail stations on crime at place. We estimated Poisson regression models with fixed effects and difference in difference models to analyze crime incidents at street intersections surrounding light rail stations across varying spatial distances. Results: Our findings suggest that the expansion of the light rail system led to an increase in crime around train stations. We observe a significant intervention effect across multiple crime categories and spatial distances. These analyses suggest the effect appears stronger after the expansion of light rail service to additional train stations. Conclusions: These results have implications for a wide range of community stakeholders involved with the planning of public transportation. Given the evolving demand for transit systems, our findings highlight the need for crime prevention policies to accompany infrastructure expansion and mitigate crime.

A central tenet of the criminal decision-making literature is that perceptions of the environment shape decisions. Yet the underlying mechanisms linking environmental features to perception remain mostly untested. Those that have been tested have relied on methods that are either correlational or have limited generalizability. We aimed to fill this gap by harnessing the power of virtual reality. Using burglary as a case study, incarcerated residential burglars with varying degrees of proficiency (N = 160) explored a virtual neighborhood with houses that differed in features related to the risks and rewards of burglary. In support of our preregistered hypotheses, offenders adjust their perceptions in response to environmental features related to risks and rewards. Moreover, proficiency modifies these perceptions, with more proficient offenders believing they are less likely to get caught and seen and, as a result, more likely to break into a house. We support our statistical findings with rich data from qualitative interviews.

Considerable research shows that crime is concentrated at a few proprietary places: addresses and facilities. Emerging research suggests that proprietary places may radiate crime: activities at a place increase the risk of crime in the area around it. Weaknesses in the research create uncertainty about radiation, so we need more rigorous research. To conduct this research, we need a theory of crime radiation that operates at two spatial levels: the proprietary place and the area. This paper describes such a theory. Our theory states that crime radiation stems from the interaction between place management decisions at the place and offenders searching for opportunities in the area. Place managers create crime opportunities inside and outside their places. Offenders exploit place managers’ creations by deliberately searching for opportunities or by chancing upon the opportunities. The ways place managers and offenders interact gives rise to three types of crime radiation: hot dot, veiled dot, and cold dot. Finally, we propose questions crime scientists should answer to better understand crime radiation.

Research has typically focused on how certain types of business establishments are associated with the location of crime on street blocks. Studies in this genre, however, often have not accounted for the general business context of the block on which a business is located. This study uses a large sample of blocks in Southern California to test whether the context of businesses matters. We assess whether a nonlinear relationship exists between the total businesses on a block and crime, whether differences exist based on broad categories of businesses—consumer-facing businesses, blue-collar businesses, and white-collar businesses—and whether the mixing of businesses on a block impacts crime. The study finds strong evidence that blocks with more business mixing have higher levels of crime. A 1 standard deviation increase in business mixing is associated with 35%–95% more crime. The relationship between business mixing and crime is moderated by the size of the population on the block. Evidence also shows differences in relationships with crime between consumer-facing and white- or blue-collar businesses. Only modest evidence shows that specific business types are related to crime levels after accounting for this general business context.
