Represents METRO RTA's fixed–route transit vehicles and their respective on–board ITS equipment. On–board ITS equipment includes AVL/GPS systems, automated passenger counters (APCs), annunciators, and security cameras. In addition, some buses also have sensors to monitor health and conditions of buses (e.g. engine temperature, mileage, etc.) and can send this information to transit operations staff.

It may include a hardware security module and security management information base. | False |
|---|
| Transit Vehicle On–Board Fare Management | 'Transit Vehicle On–board Fare Management' supports fare collection using a standard fare card or other non–monetary fare medium and detects payment violations. Collected fare data are made available to the center. | False |
|---|
| Transit Vehicle On–Board Information Services | 'Transit Vehicle On–board Information Services' furnishes en route transit users with real–time travel–related information on–board a transit vehicle. Current information that can be provided to transit users includes transit routes, schedules, transfer options, fares, real–time schedule adherence, current incidents, weather conditions, non–motorized transportation services, and special events are provided. In addition to tailored information for individual transit users, it also supports general annunciation and/or display of general schedule information, imminent arrival information, and other information of general interest to transit users. | False |
|---|
| Transit Vehicle On–Board Maintenance | 'Transit Vehicle On–Board Maintenance' collects and processes transit vehicle maintenance data on–board the vehicle, including mileage and vehicle operating conditions. This maintenance information is provided to the management center and used to schedule future vehicle maintenance and repair. | False |
|---|
| Transit Vehicle On–Board Trip Monitoring | 'Transit Vehicle On–Board Trip Monitoring' tracks vehicle location, monitors fuel usage, collects operational status (doors opened/closed, running times, etc.) and sends the collected, time stamped data to the Transit Management Center. | False |
|---|
| Transit Vehicle Passenger Counting | 'Transit Vehicle Passenger Counting' collects transit vehicle loading data and makes it available to the center. | False |
|---|
| Transit Vehicle Schedule Management | 'Transit Vehicle Schedule Management' monitors schedule performance and identifies corrective actions when a deviation is detected. It provides two–way communication between the transit vehicle and center, enabling the center to communicate with the vehicle operator and monitor on–board systems. | False |
|---|
| Transit Vehicle Security | 'Transit Vehicle Security' provides security and safety functions on–board the transit vehicle. It includes surveillance and sensor systems that monitor the on–board environment, silent alarms that can be activated by transit user or vehicle operator, operator authentication, and a remote vehicle disable function. The surveillance equipment includes video (e.g. CCTV cameras), audio systems and/or event recorder systems. The sensor equipment includes threat sensors (e.g. chemical agent, toxic industrial chemical, biological, explosives, and radiological sensors) and object detection sensors (e.g. metal detectors). | False |
|---|
| Transit Vehicle Signal Priority | 'Transit Vehicle Signal Priority' provides the capability for transit vehicles to determine eligibility for priority and request signal priority at signalized intersections, ramps, and interchanges through short range communication with traffic control equipment at the roadside. | False |
|---|
| Vehicle Data Subscription Management | 'Vehicle Data Subscription Management' manages data subscriptions for an end user. It provides access to a catalog of available data, manages the necessary user information and rules that govern the data subscriptions, supports communications with data providers to collect data per the subscription rules, and makes the data available to the end user. It provides the local user interface through which a user can specify and manage subscriptions. It supports different mechanisms for collecting data for the end–user including one–time query–response as well as publish–subscribe services. | False |
|---|
| Vehicle Electric Charging Assist | 'Vehicle Electric Charging Assist' uses short range communications to coordinate with electric charging stations, providing information about the operational state of the electrical system, the maximum charge rate, and the percentage–complete of the charge. This application also receives current information about electric charging systems in the region and makes this information available to the driver on request. | False |
|---|
| Document Number | Title | Description |

| ISO 21217 | Intelligent transport systems –– Communications access for land mobiles (CALM) –– Architecture | ISO 21217 describes the communications reference architecture of nodes called "ITS station units" designed for deployment in ITS communication networks. While it describes a number of ITS station elements, whether or not a particular element is implemented in an ITS station unit depends on the specific communication requirements of the implementation. It also describes the various communication modes for peer–to–peer communications over various networks between ITS communication nodes. These nodes may be ITS station units as described in the document or any other reachable nodes. ISO 21217 specifies the minimum set of normative requirements for a physical instantiation of the ITS station based on the principles of a bounded secured managed domain. |

| NIST FIPS PUB 140–2 | Security Requirements for Cryptographic Modules | This Federal Information Processing Standard (140–2) specifies the security requirements that will be satisfied by a cryptographic module, providing four increasing, qualitative levels intended to cover a wide range of potential applications and environments. The areas covered, related to the secure design and implementation of a cryptographic module, include specification; ports and interfaces; roles, services, and authentication; finite state model; physical security; operational environment; cryptographic key management; electromagnetic interference/electromagnetic compatibility (EMI/EMC); self–tests; design assurance; and mitigation of other attacks. |
