Book Description
The aim of travel demand modelling is to accurately estimate trips in future time periods by understanding current travel behaviours. Accurate generalized cost modelling for determining transit mode share has proven elusive. Arbitrary weight factors are used to adjust models to reflect real world modal split. It is believed that what is missing are incorporating perceptual influences, and more generally, how the satisfaction associated with a mode of transport plays into making transit a less cost-competitive and desirable travel alternative than cost models predict. This research uses experiential sampling method to capture a transit rider's perception of satisfaction in real-time by using their own smartphone as an observer. Supplemental data collected by the smartphone's built in technologies also enable tracking the rider's movements, linking perception to a physical point. A smartphone application was developed and tested to gather their perceptions and satisfaction of transit system performance. Data from the application were spatially matched to the transit authority's own automatic vehicle location and passenger count data to validate on-time performance and service loads. The results demonstrated that while a smartphone application is an effective way to collect data in real-time, and a rich dataset was produced, transit rider satisfaction is not as easily quantified as expected. Each individual has their own perceptions of what it means to be satisfied in experiencing their daily activities. Satisfaction is more effectively inferred through qualitative observation, rather than asked directly. However, the results show correlations between satisfaction and transit system performance, attributes, and the rider's sensitivity to time. Participants reported significantly lower levels of satisfaction with their trip experience when their perceived wait time was longer than actual wait time. Deploying this application to a diverse population sample may help to identify the triggers of transit rider dissatisfaction and anxiety towards determining a cost penalty against transit modal split, and where investments can be made to improve the rider experience. However, satisfaction is revealed to be a subjective concept that is difficult to measure directly.

Book Description
The role of public transportation increases as travel demand increases due to the growth in population and economics. The importance of providing a balanced public transportation has increased. In Ontario, Canada, the provincial government investing more than $17B in transit projects by the year of 2020 [28]. Consequently, planners and engineers motivated to pay more attention to mode split (mode choice) models used to estimate transit ridership. In most existing mode choice models, the likelihood of a trip maker using a transit mode (e.g. transit) is based on the generalized cost (GC) of using transit mode relative to the generalized cost of all other available modes. In conventional generalized cost formulations, transit costs are considered deterministic. It is quite evident, however, that great variability exists in the reliability of transit service and, as a result, the actual costs experienced by users. Efforts are ongoing to incorporate the costs of reliability in mode choice models by extending formulations to include penalties for arriving prior to or later than a desired arrival time. Transit operators strive to provide reliable service to retain and attract more users. Unreliable service can adversely affect the user by arriving late or early at their destination, waiting longer at their boarding station, and spending more time than expected in the transit vehicle. Unreliable service will also increase the user's anxiety associated with the uncertainty and discomfort. All these factors should be considered explicitly within the generalized cost (GC) function in order to accurately capture the GC of transit service relative to other modes and to ensure that these factors are not incorporated within the mode specific constant. In this study, a GC model is developed that explicitly represents service reliability. Service reliability is represented in the model as penalties associated with passengers' late arrival, early arrival, departure time shifting, waiting time, and anxiety. Furthermore, a methodology of utilizing field data to capture service reliability is defined. A Monte-Carlo simulation framework has been developed using the proposed GC function to quantify the impact of transit reliability on transit user cost. The proposed framework was applied on the iXpress service in the Regional of Waterloo in Ontario, Canada, utilizing Automated Vehicle Location (AVL) system data from the Regional Municipality of Waterloo to estimate service reliability. All the coefficients included in the proposed GC are assumed based on the relative importance of each penalty to scheduled in vehicle time by considering different passenger classes. In this research, the transit passengers are assumed to belong to one of three passenger classes based on their risk tolerance. From the results, it was found that increasing reliability of arrivals at a station can decrease transit users generalized costs significantly. We further posit that including uncertainty in the calculation of generalized costs may provide better estimates for mode split in travel forecasting models.

Book Description
This report consists of a Handbook and a Workbook. The Handbook identifies and describes passenger amenities and transit vehicle characteristics that attract ridership and explores how amenities may affect ridership. The Workbook includes information gathered from passenger surveys, focus groups, discussion sessions, and transit agency staff on the effect of recently implemented transit amenities on passengers. As a companion to the Workbook, a disk, "The Transit Design Game, " enables transit agencies to survey their customers about their priorities for enhancements and estimate the potential effect of enhancements on ridership. The intended audience includes transit planners, designers, general managers, and project managers; transportation policy makers; city and regional planners; and suppliers, vendors, and manufacturers.

Book Description
Public Transportation Quality of Service: Factors, Models, and Applications is the first book to help researchers better understand the contributing factors that can improve public transportation perception among users. The book compiles in one place metrics currently dispersed in journal articles, government publications and book chapters. It critically analyzes currently available modeling methodologies such as the Ordered Logit/Probit model and Models of Structural Equations, highlighting their advantages and disadvantages. The book addresses models of desired quality, including the views of users and non-users, discussing the gap between desired and perceived quality. The book also examines data mining approaches such as decision trees and neural networks, showing how to involve the public in the decision-making process to create policies that encourage public transport demand. Measuring passenger's views on public transportation is of critical concern to promote wider transit use in cities around the world. - Includes insights from both theoretical and practical points of view for both researchers and practitioners - Features case studies in each chapter that apply models discussed - Helps readers develop and design their own studies for measuring quality of service - Shows how to include perceived quality in contracts - Provides access to the survey formulas and data to better enable implementation of models

Book Description
Providing a comprehensive overview and analysis of the latest research in the growing field of public transport studies, this Handbook looks at the impact of urbanisation and the growth of mega-cities on public transport. Chapters examine the significant challenges facing the field that require new and original solutions, including congestion and environmental relief, and the social equity objectives that justify public transport in cities.

Book Description
"These guidelines are intended for transportation practitioners involved in the planning, design, and operation of congestion-pricing projects. They will help agencies select or develop measures to evaluate these projects, collect the necessary data, track performance, and communicate the results to decision makers, users, and the general public. These guidelines will be valuable to all agencies who are using or considering congestion pricing to manage their roadway capacity."--Foreword.
