The National Highway Traffic Safety Administration (NHTSA) has proposed to perform research involving the collection of information from the public as part of a multi-year effort to learn about how humans interact with driving automation systems (DAS). This research will support NHTSA in understanding the potential safety challenges associated with human-DAS interactions, particularly in the context of mixed traffic interactions where some vehicles have DAS and others do not. Within mixed traffic environments, vehicles may also have DAS that perform more or less of the driving task (i.e., different levels of automation) and come with their own sets of expectations and limitations. This research will add to the state of knowledge and is not immediately intended to inform regulations or policy.
The research will be conducted in three parts, referred to as Study 1, Study 2, and Study 3. All study procedures will be approved by the University of Iowa Institutional Review Board (IRB). Data collection will begin upon receipt of PRA clearance and will involve human-subjects data collection using the driving simulators at the University of Iowa Driving Safety Research Institute (DSRI).
The objective of the first study is to understand how humans interact with DAS in mixed traffic environments. In the first study, participants will participate in pairs with each participant driving a separate driving simulator but interacting in the same driving environment. Participants will experience one of two driving automation systems. Both members of the participant pair will provide informed consent, a pre-drive questionnaire, a training presentation, a familiarization drive, wellness questionnaires to screen for simulator sickness, a study drive, in-drive ratings of trust, and a post-drive questionnaire and risk-propensity assessment. During the simulator drives, one member of the pair will perform a continuous drive along a specified route. The other member of the pair will complete three short drives where they interact with the other participant at specific points throughout the drive. The simulator will collect vehicle data (e.g., brake inputs, steering wheel angle) and data about the surrounding environment (e.g., distance to surrounding vehicles and lane markings). After the drives, participants will complete a questionnaire to assess their understanding of the DAS and their trust in and acceptance of the DAS. Data will be analyzed to understand how human drivers interact with DAS in mixed traffic situations and to understand how humans understand and perceive automation in different situations.
In the second study, participants will complete a drive in a driving simulator with a driving automation system. The study drive will contain situations to which the DAS must respond. Participants will be randomly assigned to one of three systems with different capability, defined by how well the automation can navigate the set of test situations. The simulator will collect vehicle data (e.g., brake inputs, steering wheel angle) and data about the surrounding environment (e.g., distance to surrounding vehicles and lane markings). After the drives, participants will complete a questionnaire to assess their understanding of the DAS and their trust in and acceptance of the DAS as well as a risk-propensity assessment. Data will be analyzed to understand how human drivers interact with DAS in mixed traffic situations and to understand how humans understand and perceive automation in different situations.
In the third study, participants will complete a drive in a driving simulator with a driving automation system. The study drive will contain situations to which the DAS must respond. Participants will be randomly assigned to one of three systems with different capability, defined by how well the automation can navigate the set of test situations. Outside of this, study procedures are the same as those for the second study.
On behalf of this Federal agency, I certify that the collection of information encompassed by this request complies with 5 CFR 1320.9 and the related provisions of 5 CFR 1320.8(b)(3).
The following is a summary of the topics, regarding the proposed collection of information, that the certification covers:
(i) Why the information is being collected;
(ii) Use of information;
(iii) Burden estimate;
(iv) Nature of response (voluntary, required for a benefit, or mandatory);
(v) Nature and extent of confidentiality; and
(vi) Need to display currently valid OMB control number;
If you are unable to certify compliance with any of these provisions, identify the item by leaving the box unchecked and explain the reason in the Supporting Statement.
