Severity Analysis of Multi-Truck Crashes on Mountain Freeways Using a Mixed Logit Model [PDF]

open access: goldSustainability, 2023
Many studies have analyzed the road characteristics that affect the severity of truck crashes. However, most of these studies have only examined road alignment or grade separately, without considering their combined effects.

logitr: Fast Estimation of Multinomial and Mixed Logit Models with Preference Space and Willingness-to-Pay Space Utility Parameterizations [PDF]

open access: yesJournal of Statistical Software, 2023
This paper introduces the logitr R package for fast maximum likelihood estimation of multinomial logit and mixed logit models with unobserved heterogeneity across individuals, which is modeled by allowing parameters to vary randomly over individuals ...

A Federated Mixed Logit Model for Personal Mobility Service in Autonomous Transportation Systems

open access: yesSystems, 2022
Looking ahead to the future-stage autonomous transportation system (ATS), personal mobility service (PMS) aims to provide the recommended travel options based on both microscopic individual travel demand and the macroscopic supply system objectives. Such

Biases in the Maximum Simulated Likelihood Estimation of the Mixed Logit Model [PDF]

open access: goldEconometrics
In a recent study, it was demonstrated that the maximum simulated likelihood (MSL) estimator produces significant biases when applied to the bivariate normal and bivariate Poisson-lognormal models.

Integrating a Pareto-Distributed Scale into the Mixed Logit Model: A Mathematical Concept [PDF]

open access: goldMathematics, 2023
A generalized multinomial logit (G-MNL) model is proposed to alleviate the four challenges inherent to the conditional logit model, including (1) simultaneous unidentifiability, (2) the immediacy of decision-making, (3) the homogeneity of preferences in ...

Mixed logit model based diagnostic analysis of bicycle-vehicle crashes at daytime and nighttime

open access: yesInternational Journal of Transportation Science and Technology, 2022
Cycling provides an important alternative to environmental-friendly transportation modes in urban areas. However, cyclists are vulnerable road users and often suffer severe injuries once crashes occur, which has impeded the growth of bicycle uses ...
