Projects

This project collects and evaluates lifecycle data for critical hydrogen renewable pathways. It also evaluates potential supply & demand for hydrogen as a vehicle fuel.

This project applies a life cycle analysis to light-duty vehicle greenhouse gas emissions, and uses the results to inform emissions reduction policies.

This project identified knowledge gaps and other barriers to wider implementation of permeable pavements. It involved a workshop that discussed plans for improved pavement policy.

This project developed a set of traffic simulation models for the Los Angeles/Long Beach region that allowed the researchers to evaluate impacts on transportation system efficiency and on the environment.

This project addresses train system delays by establishing models to optimize the balance of freight demand across rail and truck modes.

This project examines how shared mobility services are changing transportation supply and demand. The researchers specifically focus on differences between millennials and Generation X individuals.

This study compares hydrogen fuel cell and battery electric trucks across a variety of applications including short haul drayage, medium-duty urban, vocational, and long haul. Goals will include understanding which technology is best suited for specific applications, what is a reasonable rate of market penetration for zero emissions vehicles (ZEVs), and how continued improvements in battery and hydrogen storage technologies will reduce barriers to sales of ZEV MD/HD vehicles.

This project studies rural road networks that are vulnerable to extreme weather events and are necessary for accessing food.

This project examines various stakeholder interests to evaluate whether on-demand ride-hailing will help or will undermine sustainable transportation systems.

This project tests the potential for fully permeable pavement as a way to manage stormwater runoff.

The researchers aim to answer whether the presence of rail transit increases the outflow of lower-income neighborhood residents in Los Angeles County.
