Revision with unchanged content. Driving behavior models, which focus on acceleration, lane changing and gap acceptance decisions are essential to microscopic traffic simulation models and important to several other fields of transportation science and engineering. In this book, a framework for driving behavior modeling that integrates the various decisions driver make is developed, implemented and tested. This framework is based on the concepts of short-term goal and short-term plan, which captures inter-dependencies among the various decisions a driver makes as well as their planning and anticipation capabilities. Based on these concepts an integrated driving behavior model that captures both acceleration and lane changing behaviors is specified, estimated using detailed trajectory data and implemented and validated within a microscopic traffic simulation model. This book is addressed to modelers in transportation and traffic engineering and researchers and developers of traffic simulation models.
