This paper offers an econometric model system that simultaneously considers six different activity-travel choice dimensions in a unifying framework. The six dimensions include residential location choice, work location choice, auto ownership, commuting distance, commute mode, and number of stops on commute tours. The paper presents the modeling methodology in detail as well as estimation result...

Transportation modes, including Walking and other private modes as well as transit services, provide travel options to the individual trip-maker along a transportation network. On a single basis, any modal option is featured here in terms of travel time to destination conditionally to immediate availability, expected wait time in the adverse case and the probability of availability. The paper i...

Greenhouse gas emissions from personal transport have risen steadily in the UK and most other countries of the EU. Yet surprisingly little is known about who exactly is contributing to the problem at the personal level and the extent to which different groups of the population will be affected by the any responses to the climate change problem. This paper describes an innovative methodology and...

Travel time is very critical for emergency response and emergency vehicle (EV) operations. Compared to ordinary vehicles (OVs), EVs are permitted to break conventional road rules to reach the destination within shorter time. However, very few previous studies address the travel time performance of EVs. This study obtained nearly 4-year EV travel time data in Northern Virginia (NOVA) region usin...

This paper uses an endogenous segmentation approach to model mode choice. This approach jointly determines the number of market segments in the travel population, assigns individuals probabilistically to each segment, and develops a distinct mode choice model for each segment group. The author proposes a stable and effective hybrid estimation approach for the endogenous segmentation model that ...

Changes in travel modes used by people, particularly reduction of the private car use, is an important determinant of effectiveness of transportation plans. Because of dependencies between the choices of residential location and travel mode, integrated modeling of these choices has been proposed by some researchers. In this paper, an agent-based microsimulation model has been developed to evalu...
