Project at a Glance

Title: Determinants of Medium and Heavy Duty Fleet Turnover

Principal Investigator / Author(s): Kurani, Kenneth

Contractor: UC Davis

Contract Number: 19RD010


Research Program Area: Emissions Monitoring & Control

Topic Areas: Behavioral Change, Greenhouse Gas Control, Greenhouse Gas Emissions, Transport


Research Summary:

To attain air quality goals, GHG reduction targets, and clean energy requirements, California's trucking fleet must transition to low-NOX technologies, alternative fuels, and zero emission vehicles wherever possible. To enhance the effectiveness of its incentive programs and the predictive accuracy of its transportation emissions modeling, CARB seeks to better understand the factors that determine medium and heavy-duty truck fleet turnover, and how their influence varies by fleet type, location and industry. Direct communication with industry sources will be used to identify the determinants of fleet vehicle turnover for trucks operating in CA, and to characterize their application to decisions affecting high-priority vocations, industries and vehicle classifications.
