Recommended Practice

Suspension of Service of a Public Transportation System and Recovery


This standard identifies strategies for transit agencies in the event of a potential suspension of service of the transit system and its recovery. For the purposes of this standard, a full or partial suspension of service could be implemented due to security or safety concerns such as an act of terrorism, an imminent security threat, a major safety hazard, extreme weather, natural disasters or other conditions identified by the agency.
