Accommodating Multiple Constraints in the Multiple Discrete-Continuous Extreme Value (MDCEV) Choice Model
(Transportation Research Board of the National Academies, 2012)
Multiple-discrete continuous choice models formulated and applied in recent years consider a
single linear resource constraint, which, when combined with consumer preferences, determines
the optimal consumption point. ...
A New Generalized Gumbel Copula for Multivariate Distributions
(2009-08)
This paper constructs a new generalized multivariate version of the Gumbel copula that, to our
knowledge, has not appeared in the statistical or mathematical literature.
Application of Socioeconomic Model System for Activity-Based Modeling
(Transportation Research Board of the National Academies, 2012)
This paper presents results from the application of a comprehensive socio-economic and
demographic model system performed in conjunction with the development of a continuous time
activity-based microsimulation model of ...
Air-Coupled Surface Wave Transmission Measurement Across A Partially Closed Surface-Breaking Crack In Concrete
(2011-06)
Previous researchers have demonstrated that the transmission of surface waves is effective to estimate the depth of a surface-breaking crack in solids. However, most of the results were obtained using a well-defined crack ...
A hazard-based duration model of shopping activity with nonparametric baseline specification and nonparametric control for unobserved heterogeneity
(Elsevier, 1996)
Activity duration is an important component of the activity participation behavior of
individuals, and therefore, an important determinant of individual travel behavior. In this paper,
we examine the factors affecting ...
Steady supercritical Taylor vortex flow
(Journal of Fluid Mechanics, 1973)
Work travel mode choice and number of non-work commute stops
(Elsevier, 1997)
The research presented here develops a joint
model of work mode choice and number of stops
during the work commute. This
model provides an improved basis to evaluate the effect of
alternative policy actions
to alleviate ...
A joint model of residential relocation choice and underlying causal factors
(Transportation Research Board of the National Academies, 2012)
Residential location choice is a key determinant of activity-travel behavior and yet, little is
known about the underlying reasons why people choose to move, or not move, residences. Such
understanding is critical to ...
Development of opportunity-based accessibility indicators
(National Academy of Sciences, 2011)
Accessibility, defined as the ease (or difficulty) with which activity opportunities can be reached
from a given location, can be measured using the cumulative amount of opportunities from an
origin within a given amount ...
A Latent-Segmentation Based Approach to Investigating the Spatial Transferability of Activity-Travel Models
(2014-07)
Spatial transferability of travel demand models has been an issue of considerable interest,
particularly for small and medium sized planning areas that often do not have the resources and
staff time to collect large scale ...
