Correcting for endogeneity due to omitted attitudes: Empirical assessment of a modified MIS method using RP mode choice data
(Elsevier, 2016)
In this paper we extend the Multiple Indicator Solution (MIS) so that it can also be used to account for endogeneity when there are interactions between observed and unobserved factors in the specification of the utility ...
Addressing endogeneity in strategic urban mode choice models
(Springer, 2020)
Endogeneity is a potential anomaly in econometric models, which may cause inconsistent parameter estimates. Transport models are prone to this problem and applications that properly correct for it are scarce. This paper ...
Representation of heteroskedasticity in discrete choice models
(PERGAMON-ELSEVIER SCIENCE LTD, 2000)
The Multinomial Legit, discrete choice model of transport demand, has several restrictions when compared with the more general Multinomial Probit model. The most famous of these are that unobservable components of utilities ...
Mode-valued differences of in-vehicle travel time Savings
(Springer, 2017)
The value of in-vehicle travel time savings (VT) estimated from mode-choice models has been sometimes found to be higher for private car than for public transportation. This mode-valued variation may seem paradoxical, if ...
Mode valued differences of in vehicle travel time savings
(Springer, 2017)
The value of in-vehicle travel time savings (VT) estimated from mode-choice models has been sometimes found to be higher for private car than for public transportation. This mode-valued variation may seem paradoxical, if ...
A pooled RP/SP mode, route and destination choice model to investigate mode and user-type effects in the value of travel time savings
(Elsevier Ltd, 2019)
Being of great importance for transportation policy appraisals, we investigate mode and user-type effects in the value of travel time savings (VTTS) using a pooled RP/SP Mixed Logit modeling approach for mode, route and ...
Mixed modelling of interurban trips by coach and train
(PERGAMON-ELSEVIER SCIENCE LTD, 1998)
A stated preference (SP) experiment for interurban trips by coach or train was designed and programmed on portable computers with the aid of specialized software. Trip characteristics and socio-economic information about ...
Confidence intervals to bound the value of time
(PERGAMON-ELSEVIER SCIENCE LTD, 2001)
The derivation of a subjective value of time (SVT) requires finding the marginal rate of substitution between travel time and cost in a travel choice model. In the typical case of models with linear-in-parameters utility ...
The selection of a mode of urban transportation: integrating psychological variables to discrete choice models
(Universidad Nacional de Colombia Sede Medellín, 2011)
A study using revealed preference surveys and psychological testswas conducted. Key psychological variables of behavior involved in the choice of transportation mode in a population sample of the Metropolitan Area of the ...
