Federal Register / Vol. 86, No. 44 / Tuesday, March 9, 2021 / Notices
needed to craft a VSSA that discusses how the safety elements were considered and, if they choose, release a summary of that assessment publicly.
Of the manufacturers and other entities who voluntarily disclose this information, NHTSA anticipates that most manufacturers and other entities will post the VSSAs online. As of December 28, 2020, NHTSA was aware of 26 VSSAs, all available online.
The safety elements are fully described in the Voluntary Guidance section section 1 of ADS 2.0, as is the VSSA. The VSSA including the public release of that summary assessment is intended to communicate to the public particularly States and consumers that entities are 1 considering the safety aspects of ADSs; 2 communicating and collaborating with DOT; 3 encouraging the self-establishment of industry safety norms for ADSs; and 4 building public trust, acceptance, and confidence through transparent testing and deployment of ADSs.
Affected Public: Entities involved in the testing and deployment of ADSs.
Estimated Number of Respondents:
20.
Frequency: On Occasion based on information from the current information collection, respondents are expected to respond, on average, once every three years.
Estimated Total Annual Burden Hours: 12,000 hours.
NHTSA is using the number of entities that have received permits from the State of California as surrogate for the number of respondents that may choose to develop and issue a VSSA. As of December 28, 2020, California has cumulatively issued permits to 58
entities to test Automated Driving Systems with drivers present, five of those entities also received permits to test without a driver present, and one
entity included on both other lists has a permit to deploy.4 At the onset of the current information collection, California had issued permits to 45
entities as of November 16, 2017, but NHTSA had expected the number to grow to 60 entities within the three years of the information collection, assuming an addition of new entrants.
For that reason, the burden hours and cost were calculated based on 60
respondents. NHTSA expects the number of potential respondents to remain at approximately 60 given the coordinated efforts of some companies on the list, the departure of some of those entities from the industry departures were not prevalent in 2017
as the industry was new, and accounting for new entrants. As a point of reference, since the previous ICR was approved, NHTSA is aware of 26
published VSSAs. Given that only 26
VSSAs have been published in three years compared to the 58 activelypermitted entities in California, NHTSA
believes that 60 respondents is an appropriate high-end for total respondents. However, based on observations of the current information, NHTSA estimates that respondents will only produce and disclose a new VSSA
once every three years. Therefore, NHTSA has revised its burden calculations to reflect estimates based on 20 respondents each year.
Components of the Voluntary Guidance in ADS 2.0 and public disclosure of the VSSA have not changed since release in 2017. NHTSA
expects the industry burden of addressing safety elements in the Voluntary Guidance to be comprised of efforts entities would already incur in normal business operation and existing documentation. While the previous ICR
calculated burden hours associated with
a potential increase in analysis and review in order to develop the VSSA, NHTSA has since determined there to be no increased documentation citing how an entity addressed the safety elements in the Voluntary Guidance.
NHTSA does not believe that any entity is documenting its safety efforts solely for the purpose of the VSSA and public disclosure. Therefore, NHTSA reduced the estimation of burden hours by 835
burden hours per respondent per year from the previous ICR.
Development and disclosure of a VSSA is expected to involve burden for format, content, and summary, varying by safety element. NHTSA estimates that each entity will spend approximately 600 hours to develop and disseminate a VSSA. This estimate of burden is comprised of efforts to transmit information from the existing format 520 hours for development into a summary format that would be consumable by the public, including data translation, analysis, and discussion of traditionally technical information 80 hours to summarize.
The total estimated burden hours for a single VSSA is calculated as 600 hours for each of the 20 respondents. The total burden hours per year is estimated at 12,000 hours, a reduction from the 86,100 hours in the previous ICR.
In summary, NHTSA estimates the total burden associated with disclosure recommendations via a VSSA would be 600 hours per respondent with 20
respondents submitting information each year. The frequency of responding is once every three years; therefore, NHTSA estimates there will be a total of 60 unique responders over the course of the next three years.
The burden hours associated with development of a VSSA are detailed in the tables below.
