A Multiple Discrete-Continuous Model for Independent- and Joint- Discretionary-Activity Participation Decisions
(Springer, 2006)
This paper presents a multiple discrete-continuous econometric structure to model the daily time-investment decisions of couples in solo- and joint- discretionary activities incorporating intra-personal and inter-personal ...
A Joint Model for the Perfect and Imperfect Substitute Goods Case: Application to Activity Time-Use Decisions
(Elsevier, 2006)
This paper formulates a model for the joint analysis of the imperfect and perfect substitute goods case. That is, it enables the modeling of choice situations where consumers choose multiple alternatives at the same time ...
An Analysis of Multiple Interepisode Durations Using a Unifying Multivariate Hazard Model
(Elsevier, 2005)
This paper jointly examines the length between successive participations in several activity purposes using a 1999 multi-week travel survey conducted in the German cities of Halle and Karlsruhe. A multivariate hazard model ...
Comprehensive Econometric Microsimulator for Daily Activity-Travel Patterns
(National Academy of Sciences, 2004)
The Comprehensive Econometric Micro-simulator for Daily Activity-travel Patterns (CEMDAP) is a micro-simulation implementation of an activity-travel modeling system. Given as input various land-use, sociodemographic, ...
Empirical Analysis of the Impact of Security Perception on Intercity Mode Choice: A Panel Rank-Ordered Mixed-Logit Model
(National Academy of Sciences, 2006)
In the aftermath of the terrorist attacks of September 11, 2001, individuals have become increasingly conscious about travel safety and security issues. Hence, in addition to travel times and costs, the perceptions about ...
An Exploratory Analysis of Joint-Activity Participation Characteristics Using the American Time Use Survey
(Springer, 2008)
This paper presents a detailed exploratory analysis of joint activity participation characteristics using the American Time Use Survey (ATUS). As a very large nationwide survey that explicitly elicited information on both ...
A Multidimensional Mixed Ordered-Response Model for Analyzing Weekend Activity Participation
(Elsevier, 2005)
The objective of this paper is to examine the frequency of participation of individuals in out-of-home non-work and non-school episodes over the weekend. A multivariate mixed ordered response formulation accommodating the ...
Modeling Household Interactions in Daily In-Home and Out-of-Home Maintenance Activity Participation
(Springer, 2005)
The activity travel patterns of individuals in a household are inter-related, and the realistic modeling of activity-travel behavior requires that these interdependencies be explicitly accommodated. This paper examines ...
Population Updating System Structures and Models Embedded in the Comprehensive Econometric Microsimulator for Urban Systems
(National Academy of Sciences, 2008)
This paper describes the development of a population update modeling system as part of the development of the Comprehensive Econometric Microsimulator for SocioEconomics, Land-use, and Transportation Systems (CEMSELTS). ...
An Exploratory Analysis of Weekend Activity Patterns in the San Francisco Bay Area
(National Academy of Sciences, 2005)
Research on travel-demand modeling has predominantly focused on weekday activity-travel patterns, with the study of the effects of commute travel on peak period traffic congestion as a major objective. In contrast, there ...
