The integration of software into transportation systems is growing and requires the adoption of safety standards and software development systems. There are several different safety standards that could be applied based on the specific category of use. The basic methodologies used in these standards can be applied to any transportation system including Ground Based systems. This paper evaluates two different safety development standards and provides a high level comparison between a well-used standard for aviation and a more recent standard for automotive that can be applied to other transportations systems with no available standards.
