Book excerpt: Research on travel behavior continues to be one of the most prominent areas in the transportation area. Planners and policymakers try to understand and manage travel behavior. Making and implementation of travel demand management (TDM) policies greatly rely on the understanding of the determinants of activity-travel patterns and travel demand. Among the activity-travel patterns, trip chaining and joint travel have received much research interest. Trip chaining is typically viewed as a home-based tour that connects multiple out-of-home activities. Joint travel is commonly defined as traveling with others. Travel demand is generally measured by trip generation and travel distances. Investigating different aspects of travel behavior helps us better understand the links between activity participation and mobility, and improves the evaluation of the transportation infrastructure investments and policies such as high occupancy vehicle (HOV) lanes and vehicle miles traveled (VMT) reduction programs. Several studies have regarded trip chaining, joint travel, trip generation, and travel distances as different dimensions of travel behavior to be examined in terms of various socio-demographics and urban form factors. However, limited work has been done to use activity-travel patterns as mediating variables and analyze how trip chaining and joint travel shape the resulting travel demand. Furthermore, relationships between travel behavior and urban form factors at out-of-home activity locations remain unclear. Based on the 2012 travel survey data from the Cleveland Metropolitan Area, this study first investigates the relationships among trip chaining, joint travel, home-based tour generation, and travel distances at three different levels: tour, individual, and household levels. Second, the influences of socio-demographics and urban form factors at tour origins and destinations on travel behavior are examined simultaneously. Lastly, while using trip chaining and joint travel as mediating variables, this study estimates the mediating effects of socio-demographics and urban form via activity-travel patterns on travel demand. The Structural Equation Modelling (SEM) approach is applied. The study reveals the existence of significant relationships between activity-travel patterns and travel demand. Trip chaining is negatively associated with joint travel. While it increases travel distances, this effects gets weakened through its indirect effect via decreased tour generation. Joint travel appears to increase tour generation but decrease the travel distances. Most socio-demographics have significant effects with expected signs on travel behavior. The analysis suggests that urban form factors at tour origins and destinations play important roles on the resulting travel demand. Some urban form factors may not have direct effects on travel demand but have significant indirect effects on tour generation or travel distances through activity-travel patterns. This research presents how activity-travel patterns shape travel demand and concludes that trip chaining and joint travel should be taken into consideration while analyzing travel demand. The findings on socio-demographics and urban form factors can be used as inputs to improve the future evaluation of transportation projects and help planners integrate land-use strategies as tools to change people’s travel behavior. This will further mitigate the negative externalities associated with our travel patterns.
Book Synopsis Urban Rhythms and Travel Behaviour by : Stefan Schönfelder
Download or read book Urban Rhythms and Travel Behaviour written by Stefan Schönfelder and published by Routledge. This book was released on 2016-02-11 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent availability of longitudinal data on individual trip making and activity behaviour has provided analysts with new insights into the structures and motives of daily life travel. Multi-week travel diary data-sets and GPS observations are exciting sources of information for the description and modelling of the variability of individual travel patterns. Through an analysis of these strong new data sets, this book questions what are the most suitable methodological tools to represent the structures of long-term travel behaviour. It also examines what the data tells us about the travellers' motives and looks at how planning should translate the findings into forecasting tools and transport strategies. In doing so, the multifaceted and ambiguous character of daily life travel is revealed, illustrating how, while sound routines in time and space seem to dominate daily life, individuals show a considerable amount of variability and flexibility in travel and activity behaviour.

Book Synopsis Exploring Regularity and Structure in Travel Behavior Using Smart Card Data by : Gabriel Goulet-Langlois
Download or read book Exploring Regularity and Structure in Travel Behavior Using Smart Card Data written by Gabriel Goulet-Langlois and published by . This book was released on 2015 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the economic opportunities fostered by large cities become more diverse, the travel patterns of public transport users become more heterogeneous. From personalized customer information, to improved travel demand models, understanding these heterogeneous travel patterns is useful for a number of applications relevant to public transport agencies. This thesis explores how smart card data can be used to analyze and compare the structure of individual travel patterns observed over several weeks. Specifically, the way in which multiple journeys and activities are ordered and combined into repeated patterns, both by the same individual over time and across individuals is evaluated from the journey sequence of each user. The research is structured around three objectives. First, we introduce a representation of individual travel patterns and develop a measure of travel sequence regularity. The mobility of each individual is modeled as a stochastic process with memory, of which each new realization represents an activity or journey. Entropy rate, a measure of randomness in the stochastic process, is used to quantify repetition in the order of journeys and activities. This analysis reveals that the order of events is an important component of regularity not explicitly captured in previous literature. Second, we develop an approach to identify clusters of travel patterns with similar structure considered with respect to public transport usage and activity patterns. Finally, we present an exploratory evaluation of the associations between the identified clusters and socio-demographic characteristics by linking smart card data to an annual travel diary survey. These three objectives are considered in the context of a practical application using the transactions of a sample of approximately 100,000 users collected between February 10th and March 10th 2015 in London.

Available in PDF, EPUB and Kindle. Book excerpt: [Truncated] A renewed interest in public transport, and particularly rail, has sparked a renaissance of Transit Oriented Development (TOD), with the aim of creating more liveable urban environments and fostering more sustainable travel behaviour. But without in-depth knowledge of the complex interactions between urban form, human activities and travel behaviour, the risk of mismatched urban planning outcomes, failing to adequately address human needs and desires, appears obvious. Hence, a debate on the relative roles of built environment and personal preferences and attitudes in shaping travel behaviour has been ongoing; however, the related empirical and theoretical research has often remained inconclusive in its findings. This research further adds to the discourse on the associations between different TOD opportunities and households' travel behaviour. There are a number of contributions that this research is making: 1) it compares various geometries and highlights the benefits of kernel density as the most appropriate spatial tool for Activity Spaces for a one-day travel diary; 2) through a data enrichment methodology, it reveals the potential for GPS methods to enhance the Activity Space measures; 3) it analyses changes in Activity Spaces as a result of changes in urban form and development of TODs; 4) it evaluates in a structural equation model the connections between TODs and travel behaviour after accounting for household preferences and self-selection; and 5) it validates findings of the multivariate model with an Artificial Neural Network for enhanced credibility and confidence in the findings. These contributions are explained briefly in the following paragraphs. After investigating the potential of Activity Space Analysis and adopting the concept as a central research element for the behavioural analysis of activity-travel patterns, Activity Space analysis was systematically examined in terms of methodology, visualisation, and practical application and subsequently deployed to evaluate urban form implications on household travel behaviour, with the aim to measure TOD success. The examination of a new public transport railway line, crossing the southern suburbs of Perth, Western Australia (WA), along a 72km long network spine, provided a real world scenario for measuring realised Activity Spaces and validation of the holistic modelling approach developed for this research.

This book was released on 2022-12-09 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides new information to understand the relationship between urban development and environmental change to the reader. How to create a sustainable and livable urban environment and realize the sustainable development goals (SDGs) of the United Nations (UN) is one of the biggest challenges in this century, even in the next centuries. The covered subject areas of this book aim at finding a way to push SDGs forward by collecting the related knowledge between urban development and its environmental implication. Specifically, the book focuses on UN SDGs 9 (industry, innovation and infrastructure), 11 (sustainable cities and communities), and 13 (climate action). Regarding the SDGs 9, this book assesses urban population mobility, urban ecosystem services, and green infrastructure to address climate change in cities. Regarding the SDGs 11, this book explores the sustainability of urban landscape change associated with urbanization based on a multi-scale perspective. Regarding the SDGs 13, this book explores the issues affecting the development of healthy cities in the context of climate change and possible ways to address them. This book focuses on newer fields related to various forms of urbanization and urban climate. Under different urbanization and development scenarios, the city and built environment are facing new challenges and become a major concern. Better understandings of related physical laws and sustainable technologies are badly needed. This book is a good reference to urban planners, city officials, citizens who are concerned about the city environment, and policymakers, as well as students studying urban structure and environment.

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.
