MINNESOTA SYSTEM INVENTORY
When developing a statewide architecture it is important have a good understanding on which stakeholders, systems, and projects are going to be interacting within the state of Minnesota. It is also important to establish agreements among the stakeholders who will be exchanging data to promote integration throughout the state.
Several systems and projects will need to interface among each other to help facilitate integration within the state of Minnesota. In order for this goal to be achieved, a system inventory is required to identify all ITS projects and systems that are being used or planned that aids in managing traffic conditions within the state of Minnesota. The system inventory for the Minnesota Statewide Architecture is presented in Table 1. This table identifies and describes the systems and stakeholders that are responsible for operations and management of their respective systems. This table will allow the Minnesota Department of Transportation (Mn/DOT) to understand the capabilities that exist within the state and what interfaces are currently being supported or need to be accommodated in the future.
Table 1 also maps each system to one or more National ITS Architecture elements. This mapping places the regional systems and stakeholders within the context of the National ITS Architecture which will facilitate the examination of integration opportunities. For systems that were not addressed by the National ITS Architecture, a user defined entity was created to ensure they are incorporated in the Minnesota Statewide Architecture. The reader should note that the column for System Name shows specific systems names in some cases and generalizes system names in other cases. This naming convention was used for the following reasons:
1. The National ITS Architecture focuses on the functions that are being performed by any given system. Since there are several agencies/systems that are performing similar functions, some system names were generalized and lump into a single category. For example every agency that operates traffic signals were not given their own grouping they have similar functionality. Similar examples exist for Traveler Information Centers, Local Emergency Management Centers, etc.
2. To ensure that the statewide architecture is kept at a manageable level.

The reader should note that the column for System Name shows specific systems names in some cases and generalizes system names in other cases. This naming convention was used for the following reasons: 1. The National ITS Architecture focuses on the functions that are being performed by any given system. Since there are several agencies/systems that are performing similar functions, some system
names were generalized and lump into a single category. For example every agency that operates traffic signals were not given their own grouping they have similar functionality. Similar examples exist for Traveler Information Centers, Local Emergency Management Centers, etc.
2. To ensure that the statewide architecture is kept at a manageable level.

MINNESOTA’S MARKET PACKAGES
The system inventory described who the players are for the Minnesota statewide architecture and what their responsibilities are for maintaining the transportation system. The next step in the development of a statewide architecture is to associate the systems identified in the system inventory with Market Packages. Market Packages are slices of the Physical Architecture that describe a particular transportation service that an agency or system is currently providing or has a desire to provide in the future. By associating the inventory with Market Packages, one will be able to obtain an initial insight as to which projects or systems are currently interacting or should be interacting with the state of Minnesota. The National ITS Architecture has identified a total of 63 Market Packages, however 32 were selected for Minnesota’s statewide architecture plus an additional Minnesota defined market package (Compliance Management). This section identifies the systems that are or will be involved in each of the selected market packages.
The next section will describe the following:
• Identification of the selected Market Package, • Definition of the Market Package, • Diagram of the Market Package, • Status of the services described as (existing or planned), and • Systems associated with the Market Package.
The reader should view each of the selected Market Packages as pieces of a puzzle of the statewide architecture. When all the Market Packages are combined they form an uncustomized statewide architecture.
Network Surveillance (ATMS01)
This market package includes traffic detectors, other surveillance equipment, the supporting field equipment, and wireline communications to transmit the collected data back to the Traffic Management Subsystem (agencies that were mapped to this category in the system inventory). The derived data can be used locally such as when traffic detectors are connected directly to a signal control system or remotely (e.g., when a CCTV system sends data back to the Traffic Management Subsystem). The data generated by this market package enables traffic managers to monitor traffic and road conditions, identify and verify incidents, detect faults in indicator operations, and collect census data for traffic strategy development and long range planning. The collected data can also be analyzed and made available to users and the Information Service Provider Subsystem (agencies that were mapped to this category in the system inventory).

Requisite incident detection capabilities are included in the freeway control market package and through the regional coordination with other traffic management and emergency management centers, weather service entities, and event promoters supported by this market package. Information from these diverse sources are collected and correlated by this market package to detect and verify incidents and implement an appropriate response. This market package provides Traffic Management Subsystem equipment that supports traffic operations personnel in developing an appropriate response in coordination with emergency management and other incident response personnel to confirmed incidents. The response may include traffic control strategy modifications and presentation of information to affected travelers using the Traffic Information Dissemination market package. The same equipment assists the operator by monitoring incident status as the response unfolds. The coordination with emergency management might be through a CAD system or through other communication with emergency field personnel. The coordination can also extend to tow trucks and other field service personnel.

Standard Railroad Grade Crossing (ATMS13)
This market package manages highway traffic at highway-rail intersections (HRIs) where operational requirements do not dictate more advanced features (e.g., where rail operational speeds are less than 80 miles per hour). Both passive (e.g., the crossbuck sign) and active warning
26
systems (e.g., flashing lights and gates) are supported. (Note that passive systems exercise only the single interface between the roadway subsystem and the driver in the architecture definition.) These traditional HRI warning systems may also be augmented with other standard traffic management devices. The warning systems are activated on notification by interfaced wayside equipment of an approaching train. The equipment at the HRI may also be interconnected with adjacent signalized intersections so that local control can be adapted to highway-rail intersection activities. Health monitoring of the HRI equipment and interfaces is performed; detected abnormalities are reported to both highway and railroad officials through wayside interfaces and interfaces to the traffic management subsystem.

Advanced Railroad Grade Crossing (ATMS14)
This market package manages highway traffic at highway-rail intersections (HRIs) where operational requirements demand advanced features (e.g., where rail operational speeds are greater than 80 miles per hour). This market package includes all capabilities from the Standard Railroad Grade Crossing Market Package and augments these with additional safety features to mitigate the risks associated with higher rail speeds. The active warning systems supported by this market package include positive barrier systems which preclude entrance into the intersection when the barriers are activated. Like the Standard Package, the HRI equipment is activated on notification by wayside interface equipment which detects, or communicates with the approaching train. In this market package, additional information about the arriving train is also provided by the wayside interface equipment so that the train's direction of travel, its estimated time of arrival, and the estimated duration of closure may be derived. This enhanced information may be conveyed to the driver prior to, or in context with, warning system activation. This market package also includes additional detection capabilities which enable it to detect an entrapped or otherwise immobilized vehicle within the HRI and provide an immediate notification to highway and railroad officials.

Demand Response Transit Operations (APTS3)
This market package performs automatic driver assignment and monitoring as well as vehicle routing and scheduling for demand response transit services. This package uses the existing AVL database to monitor current status of the transit fleet and supports allocation of these fleet resources to service incoming requests for transit service while also considering traffic conditions. The Transit Management Subsystem provides the necessary data processing and information display to assist the transit operator in making optimal use of the transit fleet. The Information Service Provider Subsystem may be either be operated by transit management center or be independently owned and operated by a separate service provider. In the first scenario, the traveler makes a direct request to a specific paratransit service. In the second scenario, a third party service provider determines the paratransit service is a viable means of satisfying a traveler request and uses wireline communications to make a reservation for the traveler.

Multi-modal Coordination (APTS7)
This market package establishes two way communications between multiple transit and traffic agencies to improve service coordination. Intermodal coordination between transit agencies can increase traveler convenience at transfer points and also improve operating efficiency. Coordination between traffic and transit management is intended to improve on-time performance of the transit system to the extent that this can be accommodated without degrading overall performance of the traffic network. More limited local coordination between the transit vehicle and the individual intersection for signal priority is also supported by this package.

Broadcast Traveler Information (ATIS1) This market package provides the user with a basic set of ATIS services; its objective is early acceptance. It involves the collection of traffic conditions, advisories, general public transportation, toll and parking information, incident information, air quality and weather information, and the near real time dissemination of this information over a wide area through existing infrastructures and low cost user equipment (e.g., FM subcarrier, cellular data broadcast). Different from the market package ATMS6--Traffic Information Dissemination--which provides the more basic HAR and DMS information capabilities, ATIS1 provides the more sophisticated digital broadcast service. Successful deployment of this market package relies on availability of real-time traveler information from roadway instrumentation, probe vehicles or other sources.

Compliance Management
In the case of the Minneapolis/St. Paul Metropolitan Area, the existing Market Packages in the National ITS Architecture did not satisfy the specific need for enforcement of traffic infractions. As such, a new Market Package (Compliance Management) was developed to strictly address this concern. The Compliance Management package is defined as follows: This package allows enforcement agencies to use the Roadway Subsystem to support equipment packages to detect red-light violation, railroad gate crossing infringements, speed compliance, and HOV lane use monitoring. This package enables the Emergency Management Subsystem to detect the violation and respond immediately, or to activate warning systems that alert drivers to their offense. The detection may be automatically linked to roadside equipment allowing for red-light detection, speed violation systems, and violation of HOV lane use. The data from the Roadway Subsystem may be sent to the Emergency Management subsystem using wireless communications with the
48
violator or vehicle owner. Notification of the offense may be transmitted to process for compliance management actions, communications, and/or enforcement. In other cases where the law prohibits such action by enforcement agencies, compliance management may consist of roadway technologies, for example, that will sense excessive speeds and triggers a message board, warning the violator of the speeding infraction.
The following systems identified in the inventory providing this transportation service are existing.
• Compliance Roadside Equipment • Metro Local Police Centers • State Patrol Dispatch Centers
MINNESOTA STATEWIDE ARCHITECTURE
The following sections will illustrate Minnesota’s Statewide Architecture. The architecture is based on the inventory and the transportation services identified in the previous sections. Minnesota’s statewide architecture is represented by a series of tables. The information exchanges between stakeholders are identified in the statewide architecture. This documentation will allow agencies to examine the existing and planned interfaces they have among each other and work together to reach agreements on implementation of certain interfaces.
System Interconnections
System interconnections describe which agencies are currently exchanging information or have plans to exchange information in the future. The interconnections between the various systems, which were defined in Table 1 of the system inventory, are shown in Appendix A. Appendix A is a listing of tables of the various interconnects for each system identified in Minnesota’s statewide architecture. Each table has three columns (elements, elements and status). The element columns represent an agency or system that is either sending or receiving information to/from another agency or system (e.g., Table A2. Broadcast Information Providers) Table A2 shows that Broadcast Information Providers is exchanging information with the Demand Transit Responsive Center. This information exchange is existing and can be bi-directional.
System Interconnects are the starting point for stakeholders to become familiar with the overall environment in which they operate. Once stakeholders are in agreement with the system interconnects, they can then further explore these interconnections for their information content. The information content of system interconnects is described in the next section.
System Interfaces and Information Exchanges
In order to explore the next level of detail in the Minnesota’s Statewide Architecture, one needs to examine the information exchange between the systems interconnects. At the information exchange level, it is evident what information is shared between the system interconnects identified in Appendix A. The information content of the interconnects is captured in Appendix B. Appendix B is a listing of tables that illustrates the information exchanges among the systems in the Minnesota Statewide Architecture. Each table has five columns, which are described below:
• Source Element – the point in which the data is being collected and sent from. • Flow Name – the name of the information flow carrying the content information.
49
• Flow Description – description of the information contents of the flow name. • Destination Element – the receiver of the data from the source element. • Flow Status – indication of the flow name being existing information exchange or an
exchange that is planned at a later date.
Elements not defined by the National ITS Architecture are identified with an (*) because they are local functions that are important to Mn/DOT.
Potential Standards
For each information exchange between system interconnects identified in Appendix B, there are potential standards that can be examined to aid in deploying system interfaces. In order to view the potential standards for Minnesota’s Statewide Architecture, the standards report must be printed from the Microsoft Access Database. The report is not included here because it is more of an implementation concern whereas regional or statewide architectures are more of a planning concern.
Once the standards report is printed, there will be five columns used to describe the output. These are:
• Source Element – the point in which the data is being collected and sent from. • Destination Element – the receiver of the data from the source element. • Flow Name – description of the information contents of the flow name. • Standard Doc ID – the identification number of the standard document describing a
communications protocol, message set or data dictionary. • Standard Title – the name of the standards document that describes a communications
protocol, message set or data dictionary.
One might wonder how to use the information in the standards reports. Stakeholders should come together to agree upon which standards to implement for the chosen system interfaces identified in Appendix B. For example on the first page of the Standards Report, media information request is being sent from the Broadcast Information Provider to the Metro TMC. This interface shows nine potential standards that can be implemented. Stakeholders need to agree on which ones to deploy. One should also note that interrelationships exist among the various standards, and deployers may need to select more than one standard from the list of choices. For example if DATEX is the protocol of choice, the stakeholders might want to investigate the following standards for the media information request:
• Standard for Emergency Management Data Dictionary • Standard for Common Incident Management Message • Base Standard: Octet Encoding Rules (OER) • Subnet Profile for Ethernet • Internet (TCP/IP and UDP/IP) Transport Profile • Application Profile for Data Exchange ASN.1 (DATEX) • Information Profile for DATEX
Keep in mind that a suite of ITS Standards is needed to fully standardize the communications protocol, message sets and data elements. The goal is to end up with a protocol, message sets, and data dictionaries that all work together. Also future design decisions should take the chosen standards into account.
Standards are an essential part of system integration. Several ITS standards activities are currently in development by the Standard Development Organizations (SDO). These standards address particular interfaces identified in the National ITS Architecture.
50
In ITS, standards development activities have been allocated to the following organizations:
• AASHTO (American Association of State Highway and Transportation Officials) • ANSI (American National Standards Institute) • ASTM (American Society for Testing and Materials) • IEEE (Institute of Electrical and Electronics Engineers) • ITE (Institute of Transportation Engineers) • NEMA (National Electrical Manufacturers Association) • SAE (Society of Automotive Engineers)
Although each standards activity is allocated to a single SDO, it should be noted that many of the standards efforts are collaborative between multiple SDOs (e.g., NTCIP Joint Steering Committee is comprised of representatives from AASHTO, ITE and NEMA).
For the Minnesota Statewide Architecture, the applicable standards are being developed by five standards development organizations: AASHTO, ASTM, ITE, IEEE, and SAE. Table 2 lists the web sites of the SDO home pages (e.g., IEEE) as well as specific ITS Standards efforts (e.g., TMDD). Note: The ITS Standards specific internet addresses may change in the future.

It also contains links to the organizations involved and, where possible, provides rapid access to published standards documents. The U.S. DOT Joint Program Office Standards site (www.its.dot.gov/standard/standard.htm) provides current status on the standards acceleration program.
The identified web site links may change from time-to-time. A current set of links to these sites will be maintained on the National ITS Architecture website at www.iteris.com/itsarch.
51
HOW TO USE THE STATEWIDE ARCHITECTURE
It is recommended that stakeholders should use this document in the following manner. If a stakeholder wanted to see how they are represented in Minnesota’s Statewide Architecture, they would start with the system inventory and locate their system (e.g., Metro TMC). In order to see how Metro TMC is associated with other systems, the stakeholder should refer to the respective system interconnect table. In this example, Metro TMC system interconnect table is Table A14. The system interconnects show that Metro TMC is sharing data with specific traffic and public safety organizations. In some cases general organizations may have been defined that contain similar interfaces in order to reduce complexity (e.g., local signal centers). The system interconnects also shows which organizations need to have discussions and potential agreements in place if enhancements are to the Metro TMC. Once the appropriate stakeholders have been identified, they can discuss the existing and planned information exchanges and determine how to implement certain interfaces. The information exchange tables will provide insight into the interfaces. In this example, Table B14 focuses on the Metro TMC information exchanges. Table B14 shows that incident and traffic information from transportation and public safety organizations is being used to provide congestion information to motorist and also used to coordinate incident responses. Stakeholders can then view the Minnesota Standards Reports and make decisions on which standards to investigate and potentially implement.

incidents and special events and during day-to-day operations. This flow also allows 24-hour centers to monitor and control
assets of other centers during off-hours, allows system redundancies and fail-over capabilities to be established, and
otherwise enables integrated traffic control strategies in a region.
