Discrete Choice Methods with Simulation


Book Description

This book describes the new generation of discrete choice methods, focusing on the many advances that are made possible by simulation. Researchers use these statistical methods to examine the choices that consumers, households, firms, and other agents make. Each of the major models is covered: logit, generalized extreme value, or GEV (including nested and cross-nested logits), probit, and mixed logit, plus a variety of specifications that build on these basics. Simulation-assisted estimation procedures are investigated and compared, including maximum stimulated likelihood, method of simulated moments, and method of simulated scores. Procedures for drawing from densities are described, including variance reduction techniques such as anithetics and Halton draws. Recent advances in Bayesian procedures are explored, including the use of the Metropolis-Hastings algorithm and its variant Gibbs sampling. The second edition adds chapters on endogeneity and expectation-maximization (EM) algorithms. No other book incorporates all these fields, which have arisen in the past 25 years. The procedures are applicable in many fields, including energy, transportation, environmental studies, health, labor, and marketing.
















Choice of Travel Mode and Considerations in Travel Forecasting


Book Description

Since newly created state departments of transportation have become a reality, new emphasis must be placed on inclusion of air, rail and urban transportation systems. Transportation services of all kinds will need to be improved to meet increasing travel and mode choice demand. The questions the papers in this issue of the Record pose and try to answer are: How much service should be provided? To where? Which mode? How will the modes interface and coordinate services, routes, passenger demands and schedules? Can older trip demand forecasting models be freshly applied to current trip forecasting and demand projections? The papers presented examine these questions and provide some guidance for understanding and considering the expanding demand for more travel and transportation options.
