Behavioral Responses to Congestion Pricing


Book Description

Traffic congestion is costly both in terms of time lost as well as resources squandered. Road infrastructure is also expensive to create and maintain, with current funding mechanisms falling short. While there is strong theoretical support for road pricing solutions they have been sparsely deployed in the United States. We begin with a consideration of the current theory and politics underpinning road pricing. We then turn to empirical examples of two different road pricing mechanisms: one that adapts to traffic conditions in a High Occupancy Toll (HOT) lane and another that imposes a toll varying only by time of day on a bridge. In both cases we will estimate the behavioral response of drivers to toll pricing. In the dynamic pricing context the challenge in estimation lies in the simultaneity of price and demand: the structure of dynamic tolling ensures that prices increase as more drivers enter the HOT lane. Prior research has found that higher prices in HOT lanes increase usage. We find that after controlling for simultaneity HOT drivers instead respond to tolls in a manner consistent with economic theory and that their responses to value of time and value of reliability are very large. The results highlight the importance of both controlling for simultaneity when estimating demand for dynamically priced toll roads and treating HOT lanes with dynamic prices as a differentiated product with bundled attributes. In the time-of-day pricing context we estimate commuters' responses by measuring the shift from the tolled bridge to a parallel free bridge and also how commuters adjust the timing of trips to less expensive periods. We estimate own and cross-price elasticities for the two bridges finding results in line with previous research. We also estimate the time adjustment that commuters make in response to changing toll rates. These estimates allow us to compute the benefits to toll paying commuters from decreased congestion resulting from the imposition of the tolls.










The Impact of Traffic Congestion on Household Behavior: Three Essays on the Role of Heterogeneity


Book Description

Congestion is increasing everywhere from established urban areas to growth centers. The rate of increase is greater in these rapidly growing areas of the country. With the explosion of congestion in rapidly growing areas, how does congestion influence individual decision making? The purpose of this thesis is to investigate how congestion affects people's choices. More specifically, this research considers the role of observable household attributes as conditioning factors, influencing behavioral responses to congestion. This analysis is developed through three separate essays. The first essay focuses on commuting time as the outcome of joint residential and employment decisions. The framework hypothesizes that information about individual preferences for avoiding commuting time can be revealed through the differences in spatial distributions of commuting time. Two different choice margins are selected for the next two essays: a long term margin which would be associated with residential location decisions; and short term choice margins within the context of a random utility model for non-working trips. The second essay hypothesizes that expected congestion is sufficiently important to be displayed in one of a household's most important decisions, the selection of residential location. The effect of congestion can be captured with a hedonic price framework assuming that households select residential locations based on an expected mix of trips. The focus of the third essay changes to individual trips. That is, it hypothesizes household constraints will influence an individual's sensitivity to congestion as displayed through the members' decisions to make individual trips. This process is modeled using a random utility framework with careful attention to the transformation of a trip into a choice. This research provides evidence that household characteristics influence both long and short term decisions. There is support for the hypothesis that there are some household.




Traffic Safety and Human Behavior


Book Description

This comprehensive 2nd edition covers the key issues that relate human behavior to traffic safety. In particular it covers the increasing roles that pedestrians and cyclists have in the traffic system; the role of infotainment in driver distraction; and the increasing role of driver assistance systems in changing the driver-vehicle interaction.




Behavioral Responses to Policy and System Changes 2007


Book Description

TRR no. 2010 includes 14 papers that explore the effect of the built environment on motorized and nonmotorized trip making, travel time information influence on network flow, multitasking and the value of travel time savings, revealed parking choices and the value of time, multimodality, process model of voluntary travel behavior modification, and behavioral impacts of the New Jersey Turnpike time-of-day pricing initiative. This issue of the TRR also examines modeling the timing of user responses to a new urban public transport service; automobiles, trips, and neighborhood type; impact of carpooling on trip-chaining behavior and emission reductions; willingness to pay for parking at suburban malls;impact of reduced parking standards on parking supply; telecommuting; and transportation and communications - substitutes, complements, or neither.




Traffic Management


Book Description

Transport systems are facing an impossible dilemma: satisfy an increasing demand for mobility of people and goods, while decreasing their fossil-energy requirements and preserving the environment. Additionally, transport has an opportunity to evolve in a changing world, with new services, technologies but also new requirements (fast delivery, reliability, improved accessibility). The subject of traffic is organized into two separate but complementary volumes: Volume 3 on Traffic Management and Volume 4 on Traffic Safety. Traffic Management, Volume 3 of the 'Research for Innovative Transports' Set, presents a collection of updated papers from the TRA 2014 Conference, highlighting the diversity of research in this field. Theoretical chapters and practical case studies address topics such as cooperative systems, the global approach in modeling, road and railway traffic management, information systems and impact assessment.




The Handbook of Behavioral Operations


Book Description

A comprehensive review of behavioral operations management that puts the focus on new and trending research in the field The Handbook of Behavioral Operations offers a comprehensive resource that fills the gap in the behavioral operations management literature. This vital text highlights best practices in behavioral operations research and identifies the most current research directions and their applications. A volume in the Wiley Series in Operations Research and Management Science, this book contains contributions from an international panel of scholars from a wide variety of backgrounds who are conducting behavioral research. The handbook provides succinct tutorials on common methods used to conduct behavioral research, serves as a resource for current topics in behavioral operations research, and as a guide to the use of new research methods. The authors review the fundamental theories and offer frameworks from a psychological, systems dynamics, and behavioral economic standpoint. They provide a crucial grounding for behavioral operations as well as an entry point for new areas of behavioral research. The handbook also presents a variety of behavioral operations applications that focus on specific areas of study and includes a survey of current and future research needs. This important resource: Contains a summary of the methodological foundations and in-depth treatment of research best practices in behavioral research. Provides a comprehensive review of the research conducted over the past two decades in behavioral operations, including such classic topics as inventory management, supply chain contracting, forecasting, and competitive sourcing. Covers a wide-range of current topics and applications including supply chain risk, responsible and sustainable supply chain, health care operations, culture and trust. Connects existing bodies of behavioral operations literature with related fields, including psychology and economics. Provides a vision for future behavioral research in operations. Written for academicians within the operations management community as well as for behavioral researchers, The Handbook of Behavioral Operations offers a comprehensive resource for the study of how individuals make decisions in an operational context with contributions from experts in the field.
