Costs, Reliability, Vehicle Characteristics, and Incentives are the Top Factors Influencing Freight Vehicle Technology Choices

Research Product Type

Policy Brief

California has set goals for transitioning the freight sector to near-zero-emission and zero-emission vehicles (ZEVs). California offers several incentive programs to encourage adoption of ZEVs, but purchase decisions are driven by complex factors beyond simple purchase price. Researchers at UC Davis deployed a stated-preference survey of fleet and carrier companies to collect information about vehicle purchase preferences and how they might be influenced by various incentive programs.

Dataset: Congestion reduction via personalized incentives

Research Product Type

Data

The purpose of this research is to develop real-time algorithms to reduce traffic congestion and improve routing efficiency via offering personalized incentives to drivers.

Dataset: Fostering the use of zero and near zero emission vehicles in freight operations

Research Product Type

Data

This study explored different incentives programs in California and reviewed the literature to identify other potential types of incentives to foster a change.

Dataset: NCST Caltrans project on sensor data error estimation

Research Product Type

Data

The aim of this script is to automate the process of directed network graph formation, i.e., creation of incidence matrix, node adjacency matrix, and map the sensors to appropriate links.

Development of Eco-Friendly Ramp Control for Connected and Automated Electric Vehicles

Research Product Type

Research Report

This project proposed a hierarchical ramp merging system that not only allowed microscopic cooperative maneuvers for connected and automated electric vehicles on the ramp to merge into mainline traffic flow, but also had controllability of ramp inflow rate, which enabled macroscopic traffic flow control.
