This paper studies the properties and performance of a new measure of accessibility, called the Activity-Based Accessibility (ABA) measure, and compares it to traditional measures of accessibility, including isochrone, gravity and utility-based measures. The novel aspect of the ABA is that it measures accessibility to all activities in which an individual engages and incorporates constraints su...

The ridesharing problem is to share personal vehicles by individuals (participants) with similar itineraries. A trip in the ridesharing problem is a participant and his/her itinerary. To realize a trip is to deliver the participant to his/her destination by a vehicle satisfying the itinerary requirement. In this thesis, we focus on two optimization goals: minimize the number of vehicles and min...

In this paper, we use New York City taxi trip data from 2013 and attempt to predict congestion at specific locations in the city at a given time. This paper contains the following three contributions: 1) A method for organizing origin-destination trip data and representing it as a graph; 2) Metrics that that represent congestion at a given location, including whether that location causes (injec...

A Systematic Comparison of First-Time and Repeat Visitors via a Two-Phase Online Survey Abstract: Tourism researchers report differences between first-time and repeat visitors in terms of their demographics, tripographics, destination perception, perceived value, and travel motivations. The majority of previous studies focus on comparing only one or a couple of these dimensions, with fragmented...

Taking a holiday trip is common couple-based leisure activity in which both partners tend to be actively involved. This paper studies the intra-household bargaining for choice of vacation destination within couples. We conduct discrete experiment we elicit individual and couple preferences different hypothetical travel portfolios two-stage experimental design. The choices are modelled as functi...

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...

In this paper we use Twitter data and a recently developed algorithm at the University of California Santa Barbara to extract Origin-Destination pairs in the Greater Los Angeles metropolitan area known as the Southern California Association of Governments (SCAG) region. This algorithm contains two steps: individual-based trajectory detection and place-based trip aggregation. In essence, if a pe...

Implementing decision support technologies in a real commercial tourism destination portal is challenging. First of all, the peculiar problems related to the tourism domain, which have been studied in the recent years in eCommerce and tourism research, must be considered. But, to provide an effective and useful tool, one must tackle additional requirements arising from the technical and operati...

Travel demand is well announced as a crucial component of transportation planning. This paper aims to develop a direct demand model, denoting a more acceptable abstraction of reality, for intercity passengers in daily work and leisure trips in Tehran province. The model utilizes combined estimation across the data source, collected in 2011, of travelers originating from ...
