Analysis of Safety Requirements Evolution in the Transition of Land Transportation Systems Toward Autonomy

Abstract

Autonomous Vehicles (AV) are the future evolution of Land Transportation Systems (LTS). They promise an improvement in road safety. However, safety requirements stay a big challenge for their development. The literature presents a lack of insight on the way LTS safety requirements will evolve. This paper proposes an analysis method of LTS safety requirements evolution toward AV. The ASIL metric is used to evaluate the safety criticality. The application on two case studies, the steering by wire and platooning systems, results in a better understanding and characterization of this evolution

Requirements Engineering for Embedded Systems: A Systematic Literature Review

“…Fourteen studies (15.2%) applied their solutions in more than one domain. This fact may indicate the the need to test with the appropriate indicators, the proposed solution in different domains, expanding the examples and checking the effects [25,6,23]. Hence, it may be necessary to evaluate in a second domain, a solution specially developed for a specific area.…”

“…O2 -Apply the proposed approach in different domains is the second most cited challenge. The goal is to test the proposed solution in different domains, expanding the examples and checking the effects [25,6,23].…”

A Semi-automated Requirements Reuse and Recycling Process for Autonomous Transportation Systems R&D

“…Up until now, there have been no industrialization or industrial experimentation of an ATS with an autonomy level 4 or above on the SAE scale. A shown in Damak et al (2018), the transition from the level 2 and 3 to upward levels implies a structuring change on the system's requirements. Therefore, designers face a lack of industrial feedback for R&D of level 4 ATS.…”
