Service must be operated on a regular basis by, or under contract with, a transit operator for the purpose of transporting passengers within urbanized areas, or between urbanized areas and outlying areas. Such rail service, using either locomotive hauled or self propelled railroad passenger cars, is generally characterized by multi-trip tickets, specific station to station fares, railroad employment practices and usually only one or two stations in the central business district. â Demand Response: A transit mode comprised of passenger cars, vans or Class C buses operating in response to calls from passengers or their agents to the transit operator, who then dispatches a vehicle to pick up the passengers and transport them to their destinations. A demand response operation is characterized by the following: (a) The vehicles do not operate over a fixed route or on a fixed schedule except, perhaps, on a temporary basis to satisfy a special need; and (b) typically, the vehicle may be dispatched to pick up several passengers at different pickup points before taking them to their respective destinations and may even be interrupted en route to these destinations to pick up other passengers. The
251 following types of operations fall under the above definitions provided they are not on a scheduled fixed- route basis: many origins-many destinations, many origins-one destination, one origin-many destinations, and one origin-one destination. âParatransitâ is another name for "Demand Response" service. â Ferryboat: A transit mode comprised of vessels carrying passengers and/or vehicles over a body of water, and that are generally steam or diesel-powered. â Heavy Rail: A transit mode that is an electric railway with the capacity for a heavy volume of traffic.

267 Progressive exercise program Comprised of five categories of activities for testing and evaluating the capabilities of transportation personnel to manage emergency situations using existing plans, procedures and equipment. The categories in a progressive exercise program build on each other, in both complexity and level of assessment provided for transportation management. They include: â An orientation seminar is an informal discussion designed to familiarize participants with roles, plans, procedures, and resolve questions of coordination and assignment of responsibilities. â A tabletop exercise simulates an emergency situation in an informal, stress-free environment. It is designed to elicit discussion as participants examine and resolve problems based on existing crisis management plans. â A drill is a set of supervised activities that test, develop, or maintain skills in a single response procedure (e.g., communications, notification, lockdown, and fire) and the possible or probable interaction with local government agency functions (e.g., incident command posts, rescue squad entry, and police perimeter control) that will involve actual field response. Drills help prepare for more complex exercises in which several functions are simultaneous coordinated and tested. â A functional exercise is a fully simulated interactive exercise that tests one or more functions in a time-pressured realistic situation that focuses on policies, procedures, roles, and responsibilities. â A full-scale exercise evaluates the operational capability of emergency response management systems in an interactive manner.

Risk management 2 The process of measuring or assessing risk and then developing strategies to manage the risk. Involves a prioritization process through which risks with the greatest adverse consequences and greatest probability of occurring are handled first, and risks with lower probability of occurrence and lower loss are handled later if at all. Requires balancing risks with a high probability of occurrence but lower loss against risks with high loss but lower probability of occurrence. Consists of three base components, Threat Assessment (TA), Criticality Assessment (CA), and Vulnerability Assessment (VA). Risk mitigation The actions or decisions designed to reduce the financial and nonpecuniary risk from uncertain events.

The nine-digit Social Security number is divided into three parts. The first three digits are the area number. Prior to 1973, the area number reflected the state in which an individual applied for a Social Security number. Since 1973, the first three digits of a Social Security number are determined by the ZIP code of the mailing address shown on the application for a Social Security number. The middle two digits are the group number. They have no special geographic or data significance but merely serve to break the number into conveniently sized blocks for orderly issuance.

293 Threat 1 The potential intentional act capable of disrupting or negatively affecting an asset. In other words, threats are deliberate attempts of a person or group to achieve various criminal or terrorist ends that may involve loss of life, loss of function, loss of visibility, and other objectives. Threats are distinct from hazards because they are not acts of nature, accidents, or organic happenstances for which tunnels are normally designed. Rather, threats are typically characterized as acts of intrusion; placement of explosive devices; and/or chemical, biological, or radiological attacks. In the case of terrorism, a threat consists of a scenario that combines a weapon, a host (i.e., an aggressor), a delivery mode, and tactics (i.e., a path of approach, the use of stealth or force, and the actual target of weapon placement). While hazards are associated with safety, threats are associated with security. Threat 2 Any verbal or physical behavior or communication that reasonably could be interpreted as communicating or conveying intent to cause physical harm to a person or property. Threat actor or threat agent An individual, group, organization, or government that conducts or has the intent to conduct detrimental activities. (Adapted from DHS Risk Lexicon) Threat aggressors Delivery tactics, and associated weapons, tools, or explosives against which a facility is protected; established by evaluating aggressor likelihood and objectives with respect to the assets. Threat analysis A continual process of compiling and examining all available information concerning potential threats and human-caused hazards. A common method to evaluate terrorist groups is to review the factors of existence, capability, intentions, history, and targeting. Threat analysis The detailed evaluation of the characteristics of individual threats. Threat and vulnerability assessment An evaluation performed to consider the likelihood that a specific threat will endanger the system, and to prepare recommendations for the elimination or mitigation of all threats with attendant vulnerabilities that meet predetermined thresholds. These assessments typically include both revenue and non-revenue operations. Critical elements of these assessments include: â Threat Analysis: Defines the level or degree of the threats against a specific facility by evaluating the intent, motivation, and possible tactics of those who may carry them out. â Threat Probability: The probability a threat will occur at a specific facility during its life cycle (typically quantified as 25 years). Threat probability may be expressed in quantitative or qualitative terms. An example of a qualitative threat-probability ranking system is as follows: o Frequent: Event will occur will occur within the systemâs life cycle (25 years) o Probable: Expect event to occur within the systemâs life cycle (25 years) o Occasional: Circumstances expected for that event; it may or may not occur within the systemâs life cycle (25 years)
294 o Remote: Possible but unlikely to occur within the systemâs life cycle (25 years) o Improbable: Event will not occur within the systemâs life cycle (25 years) â Threat Severity: A qualitative measure of the worst possible consequences of a specific threat in a specific facility: o Category 1 -Catastrophic. May cause death or loss of a significant component of the transit system, or significant financial loss. o Category 2 - Critical. May cause severe injury, severe illness, major transit system damage, or major financial loss. o Category 3 -Marginal. May cause minor injury or transit system damage, or financial loss. o Category 4 -Negligible. Will not result in injury, system damage, or financial loss. â Threat Resolution: The analysis and subsequent action taken to reduce the risks associated with an identified threat to the lowest practical level. â Scenario analysis: An interpretive methodology that encourages role-playing by transportation personnel, emergency responders, and contractors to brainstorm ways to attack the system. This analysis uses the results of threat analysis, paired with the systemâs list of critical assets. Transportation personnel use this analysis to identify the capabilities required to support specific types of attacks. This activity promotes awareness and highlights those activities that can be preformed to recognize, prevent, and mitigate the consequences of attacks. â Vulnerability Analysis: The systematic identification of physical, operational and structural components within transportation facilities and vehicles that can be taken advantage of to carry out a threat. This includes vulnerabilities in the design and construction of a given transit facility or vehicle, in its technological systems, and in the way it is operated (e.g., security procedures and practices or administrative and management controls). Vulnerability analysis identifies specific weaknesses with respect to how they may invite and permit a threat to be accomplished. Threat assessment The process to identify threat categories and adversaries, assessing the intent of each adversary, the capability of each adversary, the frequency of past incidents and an estimation of the threat relative to each critical asset Threat assessment (TA) Threats fall into three categories: (1) Natural Disaster Events; (2) Unintentional Events (failures, incidents); and (3) Intentional Acts or Attacks. While generalized threat information can help in risk assessment, well constructed scenario-based threat analysis represents the most effective method of establishing an effective threat threshold for a given target. Questions such as: âHow likely is the event or an attack to occur?â or âHow susceptible is the location to adverse weather?â or âHow attractive is the target?â all help inform scenario-based threat assessment.

302 Vulnerability 2 A characteristic or flaw that renders an asset or system susceptible to destruction, incapacitation, or exploitation. Vulnerability assessment Systematic examination of a critical infrastructure, the interconnected systems on which it relies, its information, or product to determine the adequacy of security measures, identify security deficiencies, evaluate security alternatives, and verify the adequacy of such measures after implementation A systematic evaluation process in which qualitative and/or quantitative techniques are applied to arrive at an effectiveness level for a safeguards and security system to protect specific targets from specific adversaries and their acts. Vulnerability assessment (VA) In general, determining the vulnerability of a critical asset is the least difficult area of risk assessment. Both quantifiable and qualitative analysis can be performed to measure the current vulnerability status of the asset, as well as the effect of ongoing risk management improvements. Similarly, the return on investment of future actions can be forecasted with some level of certainty. Vulnerability assessment considers the likeliness of a given scenario occurring by chance or intention. VA also postulates susceptibility and resultant damage.
