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.

Planning Tool

This is a spreadsheet tool that can be used to adjust available trip-generation rates for “smart growth” land use projects proposed in California.

Spatial and Temporal Energy Use and Emissions Contributions across Demographic Groups

Principal Investigator Yingping Zhao
Georgia Institute of Technology

This study will develop a framework that integrates an activity-based travel demand model with path retention, an emissions model (MOVES Matrix) and demographic analysis system (Population Synthesis).

Spatial Implications of Telecommuting in the United States

Principal Investigator Andrii Parkhomenko, Ph.D.
University of Southern California

The research team will create a quantitative spatial equilibrium model of on-site and remote worker location choice and transport demand in the contiguous United States in order to examine how the distribution of jobs and residents within and across U.S. cities would change if the 2020 surge in working from home becomes permanent, and what the effect on demand for commuting and freight transport would be.

The Effects of Ride-Hailing Services on Greenhouse Gas Emissions

Research Product Type

Policy Brief

UC Davis researchers examined how ride-hailing affects the total amount of driving (measured in vehicle miles traveled, VMT) as well as greenhouse gas (GHG) emissions
