Real World Energy Efficiency Benefits of the I-75/I-575 NWC Express Lanes in Metro Atlanta

  • Principal Investigator Randall Guensler, Ph.D.
  • Georgia Institute of Technology
This project involves expanding prior analysis of the Georgia I-75/I-575 Northwest Corridor Express Lanes by performing an energy use and emission assessment for these Express Lanes against the GP lanes on a per VMT basis.  The tools and results from this project will support assessment and public outreach efforts related to expansion of Georgia’s Express Lanes systems.

Real-Time Large-Scale Ridesharing with Flexible Meeting Points

  • Principal Investigator Maged Dessouky, Ph.D.
  • University of Southern California
This project will develop a framework that will, in real-time, match drivers to passengers and route rideshare drivers that incorporates traffic data to provide improved solutions. The resulting solution framework will use commercial traffic simulation software to achieve this goal.

Reducing Truck Emissions and Improving Truck Fuel Economy via ITS Technologies

  • Principal Investigator Petros Ioannou, Ph.D.
  • University of Southern California
This project proposes using intelligent transportation system (ITS) technologies that take into account the presence of trucks in the traffic flow. The researchers anticipate that this will improve impact on the environment by reducing fuel consumption and pollution levels in areas where the truck volume is relatively high.

Renewable Natural Gas (RNG) Technology Demonstration Phase 2

  • Principal Investigator Arun Raju, Ph.D.
  • University of California, Riverside
The project will develop an ‘Organic Resource Locator’ for the Southern California region with particular emphasis on the territory served by the Southern California Gas Company. This will be a map of technically recoverable organic resources available for energy conversion, and the potential end users.
