Spatial Alliances of Public Transit Operators: Establishing operator preferences for area management contracts with Government
Published 2006-01-01Scheduled transit services in many countries are provided by operators within geographical jurisdictions protected from competition with other public transit operators, although unprotected from competition by other modes, ...Open AccessWorking Paper -
The Effect of Service Quality and Price on International Airline Competition
Published 2006-01-01A game theoretic model, integrated with passenger’s international choice behaviour, for the competition between international airlines is developed and used to identify the role of competing service quality. The empirical ...Open AccessWorking Paper -
Heteroscedastic Control for Random Coefficients and Error Components in Mixed Logit
Published 2006-03-01Developments in simulation methods, and the computational power that is now available, have enabled open-form discrete choice models such as mixed logit to be estimated with relative ease. The random parameter (RP) form ...Open AccessWorking Paper -
Selection Bias in Value of Travel Time Savings
Published 2006-03-01In this paper we investigate the value of travel time savings. Estimation of this is in most cases based on samples using a specific mode. We use a mixed logit model to estimate the VTTS together with an auxiliary probit ...Open AccessWorking Paper -
Review of Future Provision of Motorways in New South Wales: Some Comments
Published 2006-03-01The NSW Government Premiers Department Review of Future Provision of Motorways in NSW (www.premiers.nsw.gov.au) has many of the elements required to improve the procurement of motorways (and public infrastructure generally). ...Open AccessWorking Paper -
Pricing in Dynamic Vehicle Routing Problems
Published 2006-04-01The principal focus of this paper is to study carrier pricing decisions for a new type of vehicle routing problems defined in a competitive and dynamic environment. This paper introduces the Vehicle Routing Problem in a ...Open AccessWorking Paper -
Modeling the Impact of Technological Changes on Urban Commercial Trips by Commercial Activity Routing Type
Published 2006-04-01An array of noteworthy developments in logistics practice has taken place without an equivalent and comprehensive development in urban freight transportation modeling. Part of the problem is the lack of deep understanding ...Open AccessWorking Paper -
Variability of Personal Exposure to Fine Particulates for Urban Commuters inside an Automobile
Published 2006-04-01Over the last decade, a growing body of evidence has emerged to suggest a causal link between short-duration exposure to elevated levels of fine airborne particulate matter and adverse health consequences. It is believed ...Open AccessWorking Paper -
Analysis and Evaluation of Incentive Compatible Dynamic Mechanisms for Carrier Collaboration
Published 2006-04-01This paper introduces a framework for carrier dynamic collaboration. In particular it proposes and analyzes dynamic collaborative mechanisms that are incentive compatible. The dynamic collaborative environment is characterized ...Open AccessWorking Paper -
Quantifying Opportunity Costs in Sequential Transportation Auctions for Truckload Acquisition
Published 2006-04-01The principal focus of this research is to quantify opportunity costs in sequential transportation auctions. This paper focuses on the study a transportation marketplace with time-sensitive truckload pickup-and-delivery ...Open AccessWorking Paper -
Influence of Vehicle Occupancy on the Valuation of Car Driver’s Travel Time Savings: Identifying Important Behavioural Segments
Published 2006-05-01Studies that develop estimates of the value of travel time savings (VTTS) for car travel typically assume that the VTTS of the driver is the only relevant measure of the worth of time savings. Although there is a recogntion ...Open AccessWorking Paper -
Reducing Sign Violation for VTTS Distributions through Recognition of an Individual’s Attribute Processing Strategy
Published 2006-06-01A number of authors have recently argued that the selection of the distributional assumptions in mixed logit models, used in deriving distributions of valuation of travel time savings (VTTS) to capture taste heterogeneity, ...Open AccessWorking Paper -
Approximation of Bayesian Efficiency in Experimental Choice Designs
Published 2006-06-01This paper compares different types of simulated draws over a range of number of draws in generating Bayesian efficient designs for stated choice studies. The paper examines how closely pseudo Monte Carlo, quasi Monte Carlo ...Open AccessWorking Paper -
Asymmetrical Preference Formation in Willingness to Pay Estimates in Discrete Choice Models
Published 2006-06-01Individuals when faced with choices amongst a number of alternatives often adopt a variety of processing rules, ranging from simple linear to complex non-linear treatment of each attribute defining the offer of each ...Open AccessWorking Paper -
