Southern California Regional ITS Architecture 2011 Update
Jump to:
Stakeholders
Stakeholders are identified to accommodate the data exchanges for the Southern California Regional ITS Architecture. Public sector stakeholders include federal, state and local governments representing transportation agencies and the various transportation coalitions in the region. The updated Southern California Regional ITS Architecture needs to include private sector stakeholders as well, which include the port terminal operators, railroad companies, private application and service providers.

The ITS elements identified in this Southern California Regional ITS Architecture will be implemented through a series of projects led by both public sector and private sector agencies. Key foundation systems will need to be implemented in order to support other systems and projects. Project sequencing identifies those foundation systems, projects, or infrastructure that are required to be in place for other projects to move forward. The projects included here are intentionally generic in nature and were defined as a part of this architecture development as a means to allow for a theoretical connectivity based on other projects and systems that are already in place. The intent in developing these placeholder projects and identifying sequencing is to allow future project sponsors to identify their own, funded projects within this connected, regional context, and as such to have a starting point for understanding the connectivity needed for an optimized regional system. In some cases, studies may be required prior to full project development and implementation and operational agreements may be necessary for interregional projects to effectively work together.
| Project Title | Description | Services | Status | Timeframe |
| 511 Traveler Information | Two traveler information programs provide the public with traveler information services in the SCAG region. The Motorist Aid and Traveler Information System (MATIS) program in Los Angeles County is overseen by LA SAFE and provides traveler information services via phone and web for Orange, Los Angeles, and Ventura counties primarily and a the Inland Empire 511 provides traveler information services via web and phone interfaces to the Riverside and San Bernardino areas . The LA SAFE MATIS program delivers multi-modal traveler information to the public in Southern California through a 511 interactive voice response (IVR) telephone services and 511 website (go511.com). The system was designed to be the real-time and static data collection, analysis, and dissemination tool to provide relevant traveler information to the public as well as monitor and manage service on the freeways in Los Angeles, Orange, and Ventura primarily, with data also provided for Riverside and San Bernardino counties. The system provides information about traffic drive times and freeway speeds, road construction, incidents, buses and trains, carpool/vanpool, bicycle information, and weather. Sources for real-time data include RIITS (District 7), Caltrans Traffic Management Center (District 8 and District 12), Caltrans Lane Closure System portal, California Highway Patrol CAD and Nextrip (transit vehicle status). Callers to the 511 phone system can request roadside assistance from Freeway Service Patrol (FSP) tow trucks. After working cooperatively on the LA SAFE MATIS program, the Riverside County Transportation Commission (RCTC) and the San Bernardino Association of Governments (SANBAG) formed a separate partnership to develop a 511 system for the Inland Empire. The system provides a similar traveler information service with an interactive voice response (IVR) telephone component and a 511 website (IE511.org). Traffic coverage is primarily focused on Riverside and San Bernardino counties, with data also provided for Orange, Los Angeles, Ventura, and San Diego counties. Callers do not have to distinguish between Inland Empire or the LA SAFE MATIS service; callers dial the same 511 number and are handed off to either system depending on the originating area code for landline users or the location of the receiving cell phone tower for mobile users. | ATIS01-1 - Broadcast Traveler Information - RIITS ATIS01-2 - Broadcast Traveler Information - Regional 511 Systems ATIS02-1 - Interactive Traveler Information - Regional 511 Systems |

| LA County IEN | The Los Angeles County Information Exchange Network (IEN) is a system developed by the Los Angeles County Department of Public Works (DPW) that shares information and control of municipal traffic control systems (TCS) throughout the county and is offered to agencies outside of LA County if a connection is desired. The system is interoperable with different TCS packages by using open architecture components such as a standard software interface to connect the TCS to the IEN. Agencies participating in the IEN can share and access real-time intersection data to support enhanced arterial traffic management, improve traffic operations along multi-jurisdictional corridors and coordinate emergency response. Through 2009, the TCS of eight cities are connected to the IEN backbone, with the IEN and the City of Los Angeles (LADOT) TCS exchanging data through a separate interface. An interface between the IEN and signals in the LA County DPW network is currently being planned. | ATMS06-1 - Traffic Information Dissemination - Traffic Management Centers ATMS07-1 - Regional Traffic Management - Traffic Management Center and EMC Communications ATMS07-3 - Regional Traffic Management - IEN |

| PeMS | The Freeway Performance Measurement System (PeMS) is a program that was developed jointly by the University of California at Berkeley and the California Department of Transportation to collect historical and real-time freeway data from the various freeway management systems in the state for performance measurement calculations. The detector data is transmitted from Caltrans district traffic management centers over the Caltrans WAN to the PeMS host server which aggregates the data and provides performance measurement tools to review the data on its website. Planned enhancements for PeMS include Arterial PeMS (A-PeMS) that seeks to collect, analyze and display arterial data and Transit PeMS that seeks to collect, analyze and display transit operations data. | AD2-2 - ITS Data Warehouse - SCAG ERTMIS AD3-1 - ITS Virtual Data Warehouse - SCAG ERTMIS |

| RIITS | The Regional Integration of Intelligent Transportation System (RIITS) network is the core project within the LA County Regional ITS Architecture that integrates different sources of transportation data from multiple agencies. The RIITS network features interfaces with MTA Bus, MTA Rail and Long Beach Transit for real-time transit arrival times and static schedules. The interface with Caltrans District 7 provides freeway and incident data. The RIITS network distributes the data to users through a XML data feed. The RIITS network currently supplies data to the MATIS traveler information service, local agencies, and information services providers who distribute the data to the public through a variety of applications. Future plans include data interfaces with Caltrans District 8 and 12 in neighboring counties, the Los Angeles County IEN, CHP, Foothill Transit and an archived data management system. LA Metro is currently developing an Archived Data Management Service (ADMS) that that will capture real-time data transmitted through the RIITS network. The ADMS will store three years of historical data for all modes of transportation from the various participating agencies. The ADMS database could be used to monitor system performance, support regional and corridor-level planning efforts and provide input for project funding applications.

| Universal Fare System (UFS) | The UFS will consolidate fare and revenue collection for Metro bus, Metro rail and municipal transit operators throughout Los Angeles County. The Transit Access Pass (TAP) will serve as the regional smartcard that transit users could use to pay for fares on services operated by agencies participating in the UFS. The UFS deployment includes TAP readers on buses, barrier gates / TAP readers at Metro Rail stations and a clearinghouse service center to process fare transactions. Though the TAP program serves transit users in Los Angeles County, there is potential for future interactions with Metrolink or transit providers in neighboring counties. | APTS04-1 - Transit Fare Collection Management - Universal Fare System |

The Southern California Regional ITS Architecture provides recommended current, relevant standards for each information exchange between ITS projects. Their use is not mandatory. However, in some instances, there may be funding requirements or regional policies that mandate project-specific standards such as for real-time transit information.
