Download or read book Using geographic information systems to define and map commuting patterns as inputs to agent based models written by David P. Chrest and published by RTI Press. This book was released on 2009-05-31 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: By understanding the movement patterns of people, mathematical modelers can develop models that can better analyze and predict the spread of infectious diseases. People can come into close contact in their workplaces. This report describes methods to develop georeferenced commuting patterns that can be used to characterize the work-related movement of US populations and help agent-based modelers predict workplace contacts that result in disease transmission. We used a census data product called "Census Spatial Tabulation: Census Track of Work by Census Tract of Residence (STP64)" as the data source to develop commuting pattern data for agent-based synthesized populations databases and to develop map products to visualize commuting patterns in the United States. The three primary maps we developed show inbound, outbound, and net change levels of inbound versus outbound commuters by census tract for the year 2000. Net change counts of commuters are visualized as elevations. The results can be used to quantify and assign commuting patterns of synthesized populations among different census tracts.

Download or read book GIS Based Simulation and Analysis of Intra Urban Commuting written by Yujie Hu and published by CRC Press. This book was released on 2018-11-20 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Commuting, the daily link between residences and workplaces, sets up the complex interaction between the two most important land uses (residential and employment) in a city, and dictates the configuration of urban structure. In addition to prolonged time and stress for individual commuters on traffic, commuting comes with additional societal costs including elevated crash risks, worsening air quality, and louder traffic noise, etc. These issues are important to city planners, policy researchers, and decision makers. GIS-Based Simulation and Analysis of Intra-Urban Commuting, presents GIS-based simulation, optimization and statistical approaches to measure, map, analyze, and explain commuting patterns including commuting length and efficiency. Several GIS-automated easy-to-use tools will be available, along with sample data, for readers to download and apply to their own studies. This book recognizes that reporting errors from survey data and use of aggregated zonal data are two sources of bias in estimation of wasteful commuting, it studies the temporal trend of intraurban commuting pattern based on the most recent period newly-available 2006-2010, and it focuses on commuting, and especially wasteful commuting within US cities. It includes ready-to-download GIS-based simulation tools and sample data, and an explanation of optimization and statistical techniques of how to measure commuting, as well as presenting a methodology that can be applicable to other studies. This book is an invaluable resource for students, researchers, and practitioners in geography, urban planning, public policy, transportation engineering, and other related disciplines.

Download or read book Making Community Connections written by Connie L. Knapp and published by ESRI, Inc.. This book was released on 2003 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Making Community Connections: The Orton Family Foundation Community Mapping Program is designed to bring teams of teachers and their students together with community members to study a problem, a resource, a condition -- any matter of interest and importance to the community. The school work includes gathering and examining existing information, discovering new facts through field investigation, and mapping the resource using GIS/GPS tools. Not only do the students meet and work with community mentors and experts who participate in the classroom and help with the field studies, they also typically hold public forums to gather input on the resource and their work. At the end of the semester or project the students hold a public forum to present their work in a variety of forms (including video conferences, speeches and presentations, reading of narratives, display of hand-drawn maps, GIS maps, etc.), providing a body of research to the community, which can be used to address immediate concerns and help plan for the future. The use of the word "mapping" in the name of the program indicates the importance of, and the commitment to, the use of GIS/GPS mapping technology. The Orton Family Foundation Community Mapping Program has found that the use of technology, and particularly this mapping technology, excites students and provides a powerful incentive to participate. However, the program, this book, and place-based education in general call for more than just the mapping of resources; they entail a more inclusive and integrative look at the world we all live in. Invariably, the Community Mapping Program makes more clearly visible the connections of the many and varied factors influencing or affecting the particular object of study. Concepts of sustainability, responsibility, integration, and the larger picture find their way into classroom discussions and are then mapped in a variety of ways. The materials in Making Community Connections have been constructed to provide a solid foundation and flexible framework for original projects created and developed by students, their teachers, and their communities, allowing explorations and investigations of places and problems of interest and concern to them.

Download or read book Toward Integration of Bayesian Networks with Geographic Information Systems and Complex Systems Theory for Urban Land Use Change Modelling written by Verda Kocabas Ersahin and published by . This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human-initiated land use change is the most significant factor behind the loss of agricultural and forested areas, thus global climate change. It is important to understand the reasons behind land use decisions as it is to understand their consequences. Empirical observations and controlled experimentation are not usually feasible methods for studying this change. Therefore, researchers have employed complex systems theory (or complexity theory) to help them understand and model dynamic land use change process in cities. Cellular automata (CA) theory and agent-based modeling have widely applied in land use change modelling. CA models can easily model spatial process that is changing over time, and can handle fine scale dynamics of these spatial processes. Agent-based models (ABMs) excel at relating the heterogeneous behaviour of agents with different information, different decision rules, and different situation to the macro behaviour of the overall system. While both have advantages, they have a number of challenges when applied to land use change. One of the aims of this dissertation is to develop novel modelling approaches that integrate geographic information systems (GIS), CA and ABMs with Bayesian Networks (BNs) for overcoming limitations in the modelling process by significantly reducing the tedious work in defining parameter values, transition rules and model structures. As the use of land use models in planning is not widely accepted and not trusted fully by the urban planners, the other aim is to link land use models with planning support systems (PSS), especially to use enhanced ABMs in PSS. Therefore, the proposed modelling approaches were applied to assist in understanding the patterns and controls of land use change both spatially and temporarily for the Metro Vancouver region. They were used to analyze the effects of planning decisions in accordance with the sustainable development point of view.
Download or read book Modeling Activity Selection and Scheduling Behavior of Population Cohorts Within an Activity Based Travel Demand Model System written by Mohammad Hesam Hafezi and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the time-use activity patterns of population cohorts in the region will contribute greatly to modeling spatio-temporal urban transportation demand models. The research detailed in this dissertation focuses on the development of the Scheduler for Activities, Locations, and Travel (SALT) disaggregated travel demand microsimulation model. The SALT modeling framework comprises a series of micro-behavioral modules that employ behaviorally realistic econometric, advanced machine learning, and data mining techniques to construct the 24-hour activity schedule and the corresponding travel linked with activities accomplished by individuals. A state-of-art three-dimensional, four-stage pattern recognition model is developed to identify population clusters with homogeneous time-use daily activity patterns, and to derive a representative set of activity patterns in each cluster. Each identified population cluster provides essential information related to temporal, spatial, and socio-demographic characteristics of individuals and activities, which are crucial for modeling the successive micro-behavioral modules of the SALT model. The representative behavior within each cluster is then used as an information guide for agent-based modeling. A new agent-based inference model is developed to predict various facets of the daily activity agenda, such as stop number, activity type, and activity sequential arrangement. In the next phase, temporal attributes of each activity in the agenda are predicted and the 24-hour activity schedule of all individuals is formed through a heuristic decision rule-based algorithm. Finally, a population synthesizer procedure is developed in order to implement the SALT system for the entire region. In addition, this study models the daily time-use activity patterns and estimated emission factors for university commuters, considered as a special trip generator in regional travel demand models. The data used for the analysis is from the large Halifax Space-Time Activity Research (STAR) household survey, which provides GPS-validated time-diary data for 2,778 person-days. Results show that the SALT scheduling model is able to assemble the traveler's schedule with an average 82% accuracy in the 24-hour period. The proposed simulation modeling framework is useful for urban and transport modelers to advance transportation demand management for different segments of the urban population, as well as to analyze environmental mitigation and transport policy scenarios.

This book was released on 2012-11-13 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a practical guide on how to design, create and validate a spatial microsimulation model. These models are becoming more popular as academics and policy makers recognise the value of place in research and policy making. Recent spatial microsimulation models have been used to analyse health and social disadvantage for small areas; and to look at the effect of policy change for small areas. This provides a powerful analysis tool for researchers and policy makers. This book covers preparing the data for spatial microsimulation; a number of methods for both static and dynamic spatial microsimulation models; validation of the models to ensure the outputs are reasonable; and the future of spatial microsimulation. The book will be an essential handbook for any researcher or policy maker looking to design and create a spatial microsimulation model. This book will also be useful to those policy makers who are commissioning a spatial microsimulation model, or looking to commission work using a spatial microsimulation model, as it provides information on the different methods in a non-technical way.

Download or read book Urban Informatics written by Wenzhong Shi and published by Springer Nature. This book was released on 2021-04-06 with total page 941 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book is the first to systematically introduce the principles of urban informatics and its application to every aspect of the city that involves its functioning, control, management, and future planning. It introduces new models and tools being developed to understand and implement these technologies that enable cities to function more efficiently – to become ‘smart’ and ‘sustainable’. The smart city has quickly emerged as computers have become ever smaller to the point where they can be embedded into the very fabric of the city, as well as being central to new ways in which the population can communicate and act. When cities are wired in this way, they have the potential to become sentient and responsive, generating massive streams of ‘big’ data in real time as well as providing immense opportunities for extracting new forms of urban data through crowdsourcing. This book offers a comprehensive review of the methods that form the core of urban informatics from various kinds of urban remote sensing to new approaches to machine learning and statistical modelling. It provides a detailed technical introduction to the wide array of tools information scientists need to develop the key urban analytics that are fundamental to learning about the smart city, and it outlines ways in which these tools can be used to inform design and policy so that cities can become more efficient with a greater concern for environment and equity.
