Managing the Impacts of Freight in California

Research Product Type
Policy Brief
This policy brief provides a statewide assessment of freight movement on all traffic congestion, and defines freight impact areas as severely congested roadway corridors with high volumes of trucks.

Monitoring Active Transportation Demand and Safety with Computer Vision

  • Principal Investigator Dillon Fitch-Polse, Ph.D.
  • University of California, Davis
This research will validate video- and LiDAR-based sensors to collect active transportation count data for modeling system level active transportation volume in Davis, California as a pilot for other cities and agencies.

MOVES 4.0 Updates for the Fuel and Emissions Calculator (FEC)

Research Product Type
Research Report
This project employs the outputs from MOVES-Matrix 4.0 to generate a data set that can be employed by users of the 2018 Fuel and Emissions Calculator (Version 3.0) to update energy use and emission rates to reflect the latest outputs from the U.S. Environmental Protection Agency’s MOVES 4.0 energy use and emission rate model for the Atlanta, Georgia summer scenario.

Prediction framework for parking search cruising time and emissions in dense urban areas

Research Product Type
Associated Publication
This paper: (1) uses empirical data and conducts descriptive and comparative analysis using a spatial lag model to analyze the factors influencing average cruising time (ACT) related to parking search, and (2) proposes a novel framework to predict grid-based ACT and to estimate average emission metrics (AEM).

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.

Regional Emission Analysis using Travel Demand Models

Research Product Type
Associated Publication
In this study, a tool was developed to automatically link travel demand model outputs with MOVES-Matrix to provide emissions estimates at both the link and overall inventory level.

Sensitivity Testing of Induced Highway Travel

  • Principal Investigator Yunwan Zhang, M.S.
  • University of California, Davis
This project uses a transportation demand model to examine the magnitude of potential biases to represent induced travel from expanded highway capacity.

Sensitivity Testing of Induced Highway Travel in the Sacramento Regional Travel Demand Model

Research Product Type
Research Report
This report uses the state-of-the-practice transportation demand model, the Sacramento Council of Governments SACSIM19 model, to examine (1) the model's representation of induced travel, (2) the influence of variation in key inputs on vehicle travel and roadway congestions, and (3) the effect of changes in induced travel-related input variables on the comparisons of scenarios with and without highway expansions.

Simulator Evaluation of Emerging Countermeasures for Speed Management to Reduce Conflicts with Active Transportation Users

  • Principal Investigator Fengxiang Qiao, Ph.D.
  • Texas Southern University
This project will conduct a literature review and expert survey to investigate the most promising emerging technologies for advanced speed management, such as Connected and Autonomous Vehicle technologies, Advanced Driver-Assistance System messaging, Advanced Traveler Information Systems, Advanced Vehicle Location, remote sensing and detection technologies for pedestrians, bicycles, and other similar users; advanced signal timing technologies, etc.
