Final answer:
Similarities between Transportation CI and other CIs include dependency on infrastructure and broad impact of disruptions. Unique risks in transportation involve aging infrastructure and environmental sustainability. Issues for transportation planning encompass budget allocations for expansion and maintenance, and environmental concerns.
Step-by-step explanation:
When comparing the Transportation Critical Infrastructure (CI) to other key CI sectors, there are similarities and unique risk issues that need to be evaluated. A common similarity includes the dependency on robust infrastructures and the potential for wide-reaching effects if they are disrupted. Also, much like other CI sectors, transportation requires significant investment in both the development of new roadways and the maintenance of existing ones to ensure efficiency and safety. To assess the unique risks facing transportation, one must consider the seven elements of risk, which are threats, vulnerabilities, likelihood, consequences, resilience, mitigative measures, and interdependencies within the sector.
Specifically for transportation, unique issues can manifest as the aging of infrastructure, the urgency to adopt greener options, and the cybersecurity threats to increasingly digital traffic management systems. Funding allocation for transportation often gets scrutinized, with substantial amounts required for both expansion and upkeep, making budgetary decisions a core element of transportation planning.
Environmental activists often raise concerns about the sustainability of the current commuting infrastructure, focusing on the environmental impact of roadway expansions, the need for more eco-friendly public transportation options, and the promotion of non-motorized transit means to reduce carbon emissions.
