This paper presents the regional travel forecasting model system (SACSIM) being used by the Sacramento (California) Area Council of Governments (SACOG). Within SACSIM an integrated activity-based disaggregate econometric model (DaySim) simulates each resident’s full-day activity and travel...

The goal of the study reported in this paper was to develop a comprehensive activity-based modeling system in the context of developing countries, providing accurate estimates which are expected to serve as better inputs for evaluation of different transportation policy scenarios. The case study...

The California High Speed Rail Authority (CHSRA) and the Metropolitan Transportation Commission (MTC) have developed a new statewide model to support evaluation of high-speed rail alternatives in the State of California. This statewide model will also support future planning activities of the...

While there have been many studies of urban travel demand, little attention has been paid to the analysis of inter-urban rail travel demand. Studies of inter-urban rail demand usually focus on assessment through the conventional cost benefit analysis of this type of investments, in which the...

To analyse the diversion from auto modes to combined modes such as park and ride, it is common to develop mode choice models based on discrete choice theory. In most cases, park and ride is modelled as an access mode to a main transit mode. This paper proposes an approach to test similarities...

This paper examines the determinants of foreign students' nonreturn intention to their home countries following completion of their study abroad. Such students' nonreturn is a type of brain drain. Survey data on the return intention of foreign students studying in tertiary-level courses in New...

The current paper focuses on analyzing and modeling the physical activity participation levels (in terms of the number of daily "bouts" or "episodes" of physical activity during a weekend day) of all members of a family jointly. Essentially, we consider a family as a "cluster" of individuals...

Transport investments normally reduce travel times, but may also reduce unreliability. Conventional time gains can be evaluated in cost benefit analysis using standard values of time. For valuing reliability gains, however, no standard measures are readily available. The Dutch Ministry of...

This paper describes a study undertaken to estimate a departure-time and mode-choice model for Stockholm. The model is segmented according to trip purpose, and a mixed - or error component - logit model is estimated. Estimation draws on stated preference data collected from drivers travelling...

Being diagnosed with a diet-related health condition like high blood cholesterol might compel an individual to choose a healthier diet, thereby reducing disease risks. Adding the option of medication, like statins, makes the direction of diet-quality choices theoretically ambiguous. This study...
