Data Collection and Analysis under the California Air Resources Board (CARB) Zero-and-Near-Zero Emissions Freight Facility Grant


The University of California at Riverside (UCR) will provide support for data logging and potentially portable emissions measurement systems (PEMS) testing, and chassis dynamometer. This will be conducted in support of the Port of Long Beach’s (POLB) prime contract effort with the California Air Resources Board (CARB) under the zero- and near-zero freight facility proposal. For a subset of equipment/vehicles, UCR will process and analyze the collected data to determine activity patterns including hours of operation, days of operation per year, miles traveled per day (and associated odometer reading per day and per shift if shift times are provided), average value and distribution of speed and acceleration, and idling time. We will analyze the performance of the vehicle/equipment in terms of the state of charge (SOC) throughout the work shift (minute-by-minute), fuel/energy consumption rate per work completed/distance driven, and fuel/energy consumption while idling. UCR can also provide for two weeks of PEMS testing, including travel to the site, installation and equipment preparation on-site, and actual testing. UCR can also provide for chassis dynamometer testing for a wide range of advanced technology vehicles. The basic budget includes two days of chassis dynamometer testing with CE-CERT’s heavy-duty chassis dynamometer testing facility. Measurement could include emissions for vehicles powered by natural gas, diesel, or other liquid or gas-phase fuels, standard parameters for electric vehicles consistent with the test plan outline by UCR in its guidance document for the POLB, and a combination of both emissions and EV parameters for hybrids.
