Lane Choice Model for Signalized Intersections with an Auxiliary Through Lane
JOURNAL OF TRANSPORTATION ENGINEERING, 139(4), 371–378.
author keywords: Auxiliary through lane; Operations; Intersection design; Discrete choice model; Microsimulation; Lane choice algorithm
TL;DR:
Empirically developed models for driver lane choice at signalized intersection approaches with one ATL and one continuous through lane (CTL) suggest that the utility of the ATL is a function of each through-movement driver’s arrival time.

Comparison of Flexible Fuel Vehicle and Life-Cycle Fuel Consumption and Emissions of Selected Pollutants and Greenhouse Gases for Ethanol 85 Versus Gasoline

MeSH headings : Air Pollutants / analysis; Bioelectric Energy Sources; Carbon Dioxide / analysis; Ethanol / chemistry; Gasoline / analysis; Models, Theoretical; Vehicle Emissions / analysis
TL;DR:
Evaluated differences in fuel consumption and tailpipe emissions of flexible fuel vehicles (FFVs) operated on ethanol 85 (E85) versus gasoline imply that replacing gasoline with E85 reduces CO emissions, may moderately decrease NOx tail pipe emissions, and may increase HC tailpipe emission.

Intelligent traffic data processing for ATIS applications
Journal of Transportation Engineering, 123(4), 298–307.
TL;DR:
The use of intelligent processing, or data integration tools, are proposed to overcome the data sparsity problem and make the best use of existing data resources and the elements of uncertainty and vagueness in defining and solving the problem.

Toward a class of link travel time functions for dynamic assignment models on signalized networks
TRANSPORTATION RESEARCH PART B-METHODOLOGICAL, 31(4), 277–290.
TL;DR:
This paper investigates time-dependent travel time functions for dynamic assignment on signalized arterial network links and proposes six link flow variables and corresponding link state and flow propagation equations as the basis for dynamic transportation network models.
