Transportation Iconography

The National Center for Sustainable Transportation funds a variety of research grants, organized by our four research themes (Environmentally Responsible Infrastructure and Operations; Multi-Modal Travel and Sustainable Land Use; Zero-Emission Vehicle and Fuel Technologies; and Institutional Change), and by project type (applied research projects, white papers / research synthesis, seed grants, translational projects, dissertation grants, and graduate student-led research). 

Investigation into the Aging Mechanism and Performance of Asphalt Mix Containing Crumb Rubber Modifier

  • Principal Investigator Yanlong Liang
  • University of California, Davis
This study aims to investigate asphalt binder and mix aging mechanism, especially for the asphalt containing crumb rubber modifier, and evaluate the aging effects on the asphalt mix performances. This study also aims to further evaluate the performance of the asphalt mix containing crumb rubber modifier, including the rutting resistance, fatigue life, and thermal cracking resistance.

Modeling the Impact of Road Grade on Driving Behavior, Vehicle Energy Consumption, and Emissions

  • Principal Investigator Haobing Liu
  • Georgia Institute of Technology
This study addresses two issues: 1) how road grade impacts vehicle speed and acceleration distributions, and how such distributions vary across vehicle types, roadway types, traffic conditions, etc.; and 2) how significant the impact of integrating grade interactions is with respect to energy, emissions, and air quality modeling.

Measurement and Estimation of Particulate Matter Concentration on Highways in Southern California; Characterization of Diesel Emissions using In-Door Smog Chamber

  • Principal Investigator Liem Pham
  • University of California, Riverside
In this study, both stationary and comprehensive mobile monitoring platforms were developed to measure PM concentration and traffic conditions on some major highways in Southern California. The main objective was to develop a set of alternative metrics that measure particle concentrations as well as particle size.
