We argue that significant threats to validity exist for simulation studies and that, if researchers do not actively take measures to minimize these, much of the promise of simulation will not come to pass. Further, we nominate replication as a general method to facilitate the generation of valid findings. It is anticipated, with the burgeoning interest in simulation methods in criminology, that simulation studies will be published in sufficient detail that allows researcher scrutiny and replication, with a view to developing a cumulative body of scientific knowledge. Chapter II Realistic Spatial Backcloth is not that Important in Agent Based Simulation Research: An Illustration from Simulating Perceptual Deterrence / Henk Elffers and Pieter Van Baal ...............19 This chapter considers whether it is worthwhile and useful to enrich agent based spatial simulation stud- ies in criminology with a real geographical background, such as the map of a real city? Using modern GIS tools, such an enterprise is in principle quite feasible, but we argue that in many cases this course is not only not producing more interesting results, but in fact may well be detrimental for the real rea- son of doing criminal simulation studies, which is understanding the underlying rules. The argument is first outlined in general, and then illustrated in the context of a given example of the ThESE perceptual deterrence simulation model (Van Baal, 2004), a model that actually is using a simple checkerboard as its spatial backcloth. Chapter III Visualization of Criminal Activity in an Urban Population / Alex Breuer, Joshua J. Hursey, Tonya Stroman, and Arvind Verma .......................................................................................................35 Crime is a multidimensional complex and dynamic activity. In order to understand its nature one has to comprehend not only its spatio-temporal dimensions but also the nature of crime, the victim-offender relationship, and role of guardians and history of similar previous incidents. This is a formidable task due to the limitations of present visualization methods. Both for the police department and criminal justice researcher the need to visualize a vast amount of data is a pre-requisite to the task of dealing with the crime phenomenon. This chapter presents an interactive visualization intended to present the viewer with an accurate and intuitive view of the criminal activity in a cityscape. The technique employs many different visualization elements, which taken together presents a useful methodology that can be used to visualize many of the associated factors of crime. The chapter also presents the software technique and discusses points for future investigation. Chapter IV GIS-Based Simulation and Visualization of Urban Landuse Change / Md Mahbubur R. Meenar ......50 This chapter introduces the use of geographic information systems simulations and visualizations in urban landuse changes as a means of studying spatial pattern of crime incidents. Through literature re- views the chapter provides a survey of different simulation tools and techniques that have been used in landuse planning. It also provides an overview of the models available for examining landuse changes in the context of planning processes. It argues that three-dimensional simulations of urban landuse change scenarios encourage public participation in the decision making process. The author hopes that the chapter would be useful for criminologists unfamiliar with landuse scenario simulation models and techniques. Furthermore, the chapter suggests how the crime analysts could utilize the available landuse simulation models and tools in analyzing existing crime patterns or predicting future patterns in an urban setting. Section II Streets, Networks, and Crime Distribution Chapter V Modelling Pedestrian Movement to Measure On-Street Crime Risk / Spencer Chainey and Jake Desyllas .....................................................................................................71 This chapter presents results for the first large-scale analysis of street crime rates that utilizes accurate on-street pedestrian population estimates. Pedestrian counts were generated at the street segment level for an area in central London (UK) using a modeling process that utilized key indicators of pedestrian movement and sample observations. Geocoded street crime positioned on street segments then allowed for street crime rates to be calculated for the entire central London study area’s street network. These street crime rate measures were then compared against street crime volume patterns (e.g., hotspot maps of street crime density) and street crime rate statistics and maps that were generated from using the residential population as the denominator. The research demonstrates the utility of pedestrian modeling for generating better and more realistic measures for street crime rates, suggesting that if the residential population is used as a denominator for local level street crime analysis it may only misinform and mislead the interpretation and understanding of on-street crime risk to pedestrians. The research also highlights the importance of crime rate analysis for understanding and explaining crime patterns, and suggests that with accurate analysis of crime rates, policing, and crime prevention initiatives can be improved. Chapter VI Core Models for State-of-the-Art Microscopic Traffic Simulation and Key Elements for Applications / Heng Wei ..................................................................................................92 This chapter summarizes fundamental models for microscopic simulation (such as vehicle generation model and car-following model) and other critical models (such as lane-choice model, lane-changing model, and route-choice model). Most of the critical models introduced in this chapter reflect the latest research results by the author. The primary purpose of this chapter is to provide fundamentals for better understanding of the travel behaviors that are modeled for traffic simulations. To facilitate the applica- tions of traffic simulation models, several key elements for applying state-of-the-art computer traffic simulation tools are summarized. They include the procedure for building models, model calibration and validation. Further more, techniques for collecting vehicle trajectory data, critical elements used for model calibration and validation, are also introduced. Chapter VII Simulating Urban Dynamics Using Cellular Automata / Xia Li .........................................................125 This chapter introduces the concepts of cellular automata (CA) which have been increasingly used for simulating urban dynamics. Simulation and prediction of urban evolution can provide the useful inputs to crime models. However, calibration of urban cellular automata is crucial for simulating realistic cit- ies. Simulation of multiple land use changes using CA is difficult because numerous spatial variables and parameters have to be utilized. The incorporation of neural networks with CA can alleviate the calibration problems. This chapter illustrates how complex land use dynamics can be simulated by the integration of CA and neural networks. Chapter VIII Space-Time Measures of Crime Diffusion / Youngho Kim .................................................................140 This study proposes methods for space-time diffusion measures and a simulation on crime analyses. A spatial pattern of crimes is a constantly changing and ongoing process. However, prior research on spatial crime analysis has focused primarily on identifying fixed spatial patterns, and has neglected temporal aspects. As a result, the literature has difficulty in explaining the formation and development of such spatial crime patterns. This study investigates both spatial and temporal aspects of crime occurrences, particularly on the space-time diffusion process by using the temporal extensions of local spatial autocor- relation measures. In addition, space-time diffusion simulation is applied based on Hagerstrand’s diffusion modeling. Consequently, diffusion modeling and the simulation (1) enables further understanding of the mechanism of how crime patterns are formed, (2) provides an in depth resource for policy makers and police to reduce crimes by considering a temporal dimension of crime, (3) and is readily applicable to other fields such as the epidemiology of disease. Section III Crime Event and Pattern Simulations Chapter IX Synthesis Over Analysis: Towards an Ontology for Volume Crime Simulation / Daniel J. Birks, Susan Donkin, and Melanie Wellsmith .....................................................................160 This chapter examines the use of computer simulation, specifically agent-based modelling, as a tool for criminologists and its potentially unique ability to examine, test, refine and validate criminological theory. It suggests an approach to be taken by those working in this field, through the use of detailed examples of the processes necessary to define, produce and populate both a simple model of general offending and a more detailed model for domestic burglary. It further suggests methods for evaluating such models, particularly calling for collaborative research and model replication. The authors hope that this chapter will act as a step towards an accepted ontology for volume crime simulation. Chapter X Offender Mobility and Crime Pattern Formation from First Principles / P. Jeffrey Brantingham and George Tita .............................................................................................193 Criminal opportunity in most cases is constrained by the fact that motivated offenders and potential targets or victims are not found at the same place at the same time. This ecological fact necessitates that offenders, potential victims, or both move into spatial positions that make crimes physically possible. This chapter develops a series of simple mathematical and agent-based models looking at the relationship between basic movement decisions and emergent crime patterns in two-dimensional environments. It is shown that there may be substantial regularities to crime patterns, including the tendency for crime to form discrete hotspots that arise solely from different movement strategies deployed by offenders. Chapter XI Crime Simulation Using GIS and Artificial Intelligent Agents / Xuguang Wang, Lin Liu, and John Eck ...............................................................................................209 This chapter presents an innovative agent-based model for crime simulation. The model is built on the integration of Geographic Information Systems (GIS) and Artificial Intelligence (AI) technologies. An AI algorithm (reinforcement learning) is applied in designing mobile agents that can find their ways on a street network. The multi-agent system is implemented as a Windows desktop program and then loosely coupled with ESRI ArcGIS. The model allows users to create artificial societies which consist of
