Researchers developed traffic simulation models that allowed them to evaluate the impact of new traffic flow control systems, vehicle routing, and other technologies on the efficiency of the transportation system.

In this report, the authors developed California-wide models of traffic noise and light intrusion into areas adjacent to state highways to aid understanding of wildlife responses to noise and light, and to aid locating and designing crossings to maximize wildlife approach and use.

This research project examines the link between job access and stop/station level transit ridership.

In this study, the cost-effectiveness of existing inter-city transit service in rural disadvantaged communities in the San Joaquin Valley (California) is compared to hypothetical ridesharing and carsharing services.

In this work, a literature review of key parameters that can facilitate desired CO2 uptake for transportation projects at their end of life is conducted and an initial meta-analyses of data from the literature to inform CO2 uptake for individual projects is performed.

Electrification of diesel cargo handling equipment is one method of reducing community exposure to goods movement and port related emissions, and also provides the potential for reducing greenhouse gas emissions. This study evaluated the performance of several pieces of zero emission cargo transfer equipment for a demonstration conducted at two terminal locations at the Port of Long Beach (POLB).

Given the targets for plug-in electric vehicle (PEV) penetration in the state, it is important to have a better understanding of the pattern of technology diffusion and the factors that are driving the process. Using spatial analysis and Poisson count models the researchers identify the importance of a neighborhood effect (at home locations) and a workplace effect (at commute destinations) in supporting the diffusion of PEV technology in California between 2014 and 2016.
