DOI: 10.1016/j.amar.2019.100110
Abstract: Abstract Temporal variation has been recognized as one of the major sources of unobserved heterogeneity in traffic safety research that has not been completely addressed. Overlooking temporal variation may result to biased estimates of effects… read more here.

DOI: 10.1016/j.jeconom.2019.06.006
Abstract: This paper develops nonparametric identification and estimation results for a single-spell hazard model, where the unobserved heterogeneity is specified as a Levy subordinator. The identification approach solves a nonlinear Volterra integral equation of the first… read more here.

DOI: 10.1016/j.jtrangeo.2021.102956
Abstract: Abstract Assessing the equity impacts of transportation systems/policies has become a crucial component in transportation planning. Existing statistical modeling approaches for transportation equity analysis have typically assumed that parameter estimates are constant across all observations… read more here.

DOI: 10.1016/j.tranpol.2020.08.008
Abstract: Abstract This paper aims to assess five urban transportation pricing policies (including petrol price, parking fee, taxi fare, bus fare, and metro fare). Using stated preference panel data, we estimate a mixed logit (ML) model… read more here.

DOI: 10.1080/17457300.2021.1907595
Abstract: Abstract The knot of endogeneity and unobserved heterogeneity are causes of rendering parameter estimates inconsistent in real-time crash prediction. This study intends to alleviate the potential sources of these issues in detecting critical crashes, involving… read more here.

DOI: 10.1177/1354816619841713
Abstract: Visitors to big tourist cities are very likely heterogeneous and can be classified into different segments, for example, low and high spenders. Previous studies on visitor expenditure-based segmentation seem to have only taken into account… read more here.
