Book Description
"TRB's Transit Cooperative Research Program (TCRP) Synthesis 63: On-Board and Intercept Transit Survey Techniques examines transit agencies' experiences with planning and implementing on-board and intercept surveys. On-board and intercept surveys include self-administered surveys distributed on board buses and railcars, and in stations, as well as interviews conducted in these environments. The report provides an overview of industry practices and covers a broad range of issues addressed in planning a given survey"--Publisher's description

Book Description
Geocomputation with R is for people who want to analyze, visualize and model geographic data with open source software. It is based on R, a statistical programming language that has powerful data processing, visualization, and geospatial capabilities. The book equips you with the knowledge and skills to tackle a wide range of issues manifested in geographic data, including those with scientific, societal, and environmental implications. This book will interest people from many backgrounds, especially Geographic Information Systems (GIS) users interested in applying their domain-specific knowledge in a powerful open source language for data science, and R users interested in extending their skills to handle spatial data. The book is divided into three parts: (I) Foundations, aimed at getting you up-to-speed with geographic data in R, (II) extensions, which covers advanced techniques, and (III) applications to real-world problems. The chapters cover progressively more advanced topics, with early chapters providing strong foundations on which the later chapters build. Part I describes the nature of spatial datasets in R and methods for manipulating them. It also covers geographic data import/export and transforming coordinate reference systems. Part II represents methods that build on these foundations. It covers advanced map making (including web mapping), "bridges" to GIS, sharing reproducible code, and how to do cross-validation in the presence of spatial autocorrelation. Part III applies the knowledge gained to tackle real-world problems, including representing and modeling transport systems, finding optimal locations for stores or services, and ecological modeling. Exercises at the end of each chapter give you the skills needed to tackle a range of geospatial problems. Solutions for each chapter and supplementary materials providing extended examples are available at https://geocompr.github.io/geocompkg/articles/. Dr. Robin Lovelace is a University Academic Fellow at the University of Leeds, where he has taught R for geographic research over many years, with a focus on transport systems. Dr. Jakub Nowosad is an Assistant Professor in the Department of Geoinformation at the Adam Mickiewicz University in Poznan, where his focus is on the analysis of large datasets to understand environmental processes. Dr. Jannes Muenchow is a Postdoctoral Researcher in the GIScience Department at the University of Jena, where he develops and teaches a range of geographic methods, with a focus on ecological modeling, statistical geocomputing, and predictive mapping. All three are active developers and work on a number of R packages, including stplanr, sabre, and RQGIS.

Book Description
The U.S. Dept. of Transport. (DoT) Strategic Plan for FY 1997-2002 identifies 5 performance goals: safety, mobility, econ. growth & trade, human & natural environ., & nat. security. DoT conducts the NPTS to obtain info. on personal travel of U.S. households with respect to why, how, when, where from, where to, how frequently, how long, & with whom. The NPTS also provides info. by subgroups of the pop., e.g., by age, gender, race, zero-vehicle households, which allows important policy analyses of how transport. serves these groups. This report provides the results of the 1995 NPTS of travel by the civilian, non-institutionalized pop. age 5 & older.

Book Description
This book starts from the relationship between urban built environment and travel behavior and focuses on analyzing the origin of traffic phenomena behind the data through multi-source traffic big data, which makes the book unique and different from the previous data-driven traffic big data analysis literature. This book focuses on understanding, estimating, predicting, and optimizing mobility patterns. Readers can find multi-source traffic big data processing methods, related statistical analysis models, and practical case applications from this book. This book bridges the gap between traffic big data, statistical analysis models, and mobility pattern analysis with a systematic investigation of traffic big data’s impact on mobility patterns and urban planning.

Book Description
For most tracking applications the Kalman filter is reliable and efficient, but it is limited to a relatively restricted class of linear Gaussian problems. To solve problems beyond this restricted class, particle filters are proving to be dependable methods for stochastic dynamic estimation. Packed with 867 equations, this cutting-edge book introduces the latest advances in particle filter theory, discusses their relevance to defense surveillance systems, and examines defense-related applications of particle filters to nonlinear and non-Gaussian problems. With this hands-on guide, you can develop more accurate and reliable nonlinear filter designs and more precisely predict the performance of these designs. You can also apply particle filters to tracking a ballistic object, detection and tracking of stealthy targets, tracking through the blind Doppler zone, bi-static radar tracking, passive ranging (bearings-only tracking) of maneuvering targets, range-only tracking, terrain-aided tracking of ground vehicles, and group and extended object tracking.

Book Description
The children of immigrants continue a journey begun by their parents. Born or raised in the United States, this second generation now stands over 20 million strong. In this insightful new book, immigration scholars Renee Luthra, Thomas Soehl, and Roger Waldinger provide a fresh understanding the making of the second generation, bringing both their origins and destinations into view. Using surveys of second generation immigrant adults in New York and Los Angeles, Origins and Destinations explains why second generation experiences differ across national origin groups and why immigrant offspring with the same national background often follow different trajectories. Inter-group disparities stem from contexts of both emigration and immigration. Origin countries differ in value orientations: immigrant parents transmit lessons learned in varying contexts of emigration to children raised in the U.S. A system of migration control sifts immigrants by legal status, generating a context of immigration that favors some groups over others. Both contexts matter: schooling is higher among immigrant children from more secular societies (South Korea) than among those from more religious countries (the Philippines). When immigrant groups enter the U.S. migration system through a welcoming door, as opposed to one that makes authorized status difficult to achieve, education propels immigrant children to better jobs. Diversity is also evident among immigrant offspring whose parents stem from the same place. Immigrant children grow up with homeland connections, which can both hurt and harm: immigrant offspring get less schooling when a parent lives abroad, but more schooling if parents in the U.S. send money to relatives living abroad. Though all immigrants enter the U.S. as non-citizens, some instantly enjoy legal status, while others spend years in the shadows. Children born abroad, but raised in the U.S. are all everyday Americans, but only some have become de jure Americans, a difference yielding across-the-board positive effects, even among those who started out in the same country. Disentangling the sources of diversity among today’s population of immigrant offspring, Origins and Destinations provides a compelling new framework for understanding the second generation that is transforming America.
