An Analysis Of Travel Trends Of The Elderly And Zero-Vehicle Households In The United States, Ravi Kiran Gorti
An Analysis Of Travel Trends Of The Elderly And Zero-Vehicle Households In The United States, Ravi Kiran Gorti
USF Tampa Graduate Theses and Dissertations
The elderly and persons residing in zero vehicle households require better transportation services by virtue of their need for special care and lack of mobility, respectively. An analysis of the travel trends of these population cohorts is essential to determine the best ways to improve transportation facilities to better serve them. Information about location of residence, life-cycle, differences by gender, employment status, driver status, highest level of education coupled with trip information like trip rate, travel times and distances trip purpose, modal split and percent of people immobile will facilitate understanding the factors that influence trip making among these people …
An Exploration Of The Relationship Between Mode Choice And Complexity Of Trip Chaining Patterns, Xin Ye
An Exploration Of The Relationship Between Mode Choice And Complexity Of Trip Chaining Patterns, Xin Ye
USF Tampa Graduate Theses and Dissertations
This thesis investigates the relationship between mode choice and the complexity of trip chaining patterns. An understanding of the causality between these two choice behaviors may aid in the development of tour-based travel demand modeling systems that attempt to incorporate models of trip chaining and mode choice. The relationship between these two aspects of travel behavior is represented in this thesis by considering three different causal structures: one structure in which the trip chaining pattern is determined first and influences mode choice, another structure in which mode choice is determined first and influences the complexity of the trip chaining pattern, …
Modeling Time Space Prism Constraints In A Developing Country Context, Ram S. Nehra
Modeling Time Space Prism Constraints In A Developing Country Context, Ram S. Nehra
USF Tampa Graduate Theses and Dissertations
Recent developments in microsimulation modeling of activity and travel demand have called for the explicit recognition of time-space constraints under which individuals perform their activity and travel patterns. The estimation of time-space prism vertex locations, i.e., the perceived time constraints, is an important development in this context. Stochastic frontier modeling methodology offers a suitable framework for modeling and identifying the expected vertex locations of time space prisms within which people execute activity-travel patterns. In this work, stochastic frontier models of time space prism vertex locations are estimated for samples drawn from a household travel survey conducted in 2001 in the …
Alternative Formulations Of Joint Model Systems Of Departure Time Choice And Mode Choice For Non-Work Trips, Constantinos A. Tringides
Alternative Formulations Of Joint Model Systems Of Departure Time Choice And Mode Choice For Non-Work Trips, Constantinos A. Tringides
USF Tampa Graduate Theses and Dissertations
Modeling travel demand by time of day is gaining increasing attention in travel demand forecasting practice. This is because time of day choice has important implications for mode choice and for quantifying potential modal and time of day shifts in response to traffic congestion and peak period travel demand management strategies. In this context, understanding the causal relationship between time of day (departure time) choice and mode choice behavior would be useful in the development of time of day based travel demand modeling systems both within the four-step modeling paradigm and within newer tour-based and activity-based microsimulation paradigms. This thesis …
