However, over the last six-seven months I have had innumerable discussions (both nationally and internationally) with industry, government, and academic experts about the concept of Operational Design Domain (ODD). The Motivationīe it the creation of the safety case for trials (or commercial deployment), or identifying test scenarios for CAVs, defining the Operational Design Domain (ODD) remains the first crucial step of the process. Thus, the role of ODD is especially important for higher levels of automation - SAE level 3 and SAE level 4. Why are limitations so important? Because limitations illustrate the boundaries of the ODD and when the CAV can no longer operate safely. I would like to point out here that defining the ‘limitations’ is more important (than capabilities). For example, the operating conditions (ODD) of a low-speed shuttle could include a city centre or a business park, and not a four-lane highway!īy defining the ODD, one is essentially in-part defining a CAV’s capabilities and limitations.
The CAV industry calls these ‘conditions’ - the Operational Design Domain (ODD).
An aspect of Informed Safety involves understanding ‘conditions’ in which the CAV is capable of operating safely. Informed Safety essentially means the user is aware of what a system can and cannot do. Safe deployment not only needs safe technology but also safe use of the technology, which can be achieved by imparting Informed Safety (which prevents misuse and disuse). Similarly, the thought of proving or claiming absolute safety for CAVs is unreasonable. If anyone is guaranteeing your absolute safety in these times, they would be lying to you!
However, it does mean that given we follow a set of rules (and we know why these rules exist), we may be safe. The easing of lockdown rules doesn’t mean that it is absolutely safe to be going around mingling with people. The concept of Informed Safety is very apt in the current COVID-19 situation. In a recent blog for Zenzic UK, I talked about why absolute safety is a myth and that there is a need to create Informed Safety to ensure safe deployment of Connected and Automated Vehicles (CAVs).
