On January 11, 2018, EPA released a report entitled, "Tier 3 Certification Fuel Impacts Test Program." The test program discussed in this report was initiated to compare Tier 2 certification fuel, the fuel on which the Phase 1 and Phase 2 GHG and CAFE standards were established for light-duty and heavy duty-vehicles, with the new Tier 3 certification fuel from the Tier 3 program. The test program found an overall fuel economy reduction of 1.76% for the FTP and 2.42% for the HFET for Tier 3 compared to Tier 2 test fuel. It also found that the overall test fleet showed a reduction in CO2 of 1.78% for the FTP and 1.02% for the HFET. The program results will be used as a basis for test procedure adjustments to ensure consistent stringency of GHG and fuel economy standards as vehicle certification makes the transition to Tier 3 test fuel. Additional information on the testing program is available here
On September 12, 2017, the U.S. Department of Transportation and the National Highway Traffic Safety Administration (NHTSA) released new federal guidance for Automated Driving Systems (ADS): A Vision for Safety 2.0. This is the latest guidance for automated driving systems to industry and States.
A Vision for Safety: 2.0 builds on the previous policy and incorporates feedback received through public comments and Congressional hearings. 2.0 paves the way for the safe deployment of advanced driver assistance technologies by providing voluntary guidance that encourages best practices and prioritizes safety. The document also provides technical assistance to States and best practices for policymakers.
Specifically, the new Voluntary Guidance:
- Focuses on SAE International Levels of Automation 3-5 – Automated Driving Systems (ADSs) – Conditional, High, and Full Automation);
- Clarifies the guidance process and that entities do not need to wait to test or deploy their ADSs;
- Revises unnecessary design elements from the safety self-assessment;
- Aligns Federal Guidance with the latest developments and industry terminology; and
- Clarifies Federal and State roles going forward.
As automated technologies advance, so will the Department’s guidance. It is intended to be flexible and to evolve as technology does. In fact, DOT and NHTSA are already planning for 3.0. A Vision for Safety is the newest version replacing previous guidance and offers a more flexible approach to advancing the innovation of automated vehicle safety technologies.
