Reasons for Architecture Use in Transportation Planning

Architecture represents a consensus vision of Operations and Planning stakeholders for deployment of ITS systems Addresses both short range projects and

long range strategies

Transportation Goals and Objectives

Goals • e.g., Improve transportation system reliability

Objectives• e.g., By 2020, decrease average annual

traveler delay associated with road closures, major incidents, and weather-related conditions on interstate highways by 20 percent from 2005 levels.

Goals and Objectives and the Architecture

Regional architecture should be based on operations-related goals and objectives ▬ Ensure architecture and long range plan are guided

by the same operations objectives▬ Leverage architecture traceability▬ Use Architecture to identify associated performance

measures and define a framework for performance monitoring

Objective▬ Improve traffic flows by 50%

in peak traffic periods. Operations Strategies

▬ Continue maintaining and updating traffic signal coordination in response to…changes in traffic patterns

▬ Use changeable message signs to reroute traffic in high-volume corridors

Objective: Improve traffic flows by 50% in peak traffic periods.Strategies Service Packagesa. Continue maintaining and updating traffic signal coordination in response to changes in traffic patterns.

ATMS03: Traffic Signal ControlATMS07: Regional Traffic Management (?)

b. Educate residents about alternative forms of transportation and alternative routes

Education initiatives not covered by ITS, but traveler information service packages could augment that outreach

c. Use changeable message signs to reroute traffic in high-volume corridors.

LRTP Goals, objectives,

strategies, and projects to achieve it

Covers at least the next 20 years

Leads to an intermodal system

Fiscally constrained Must be updated every

4-5 years

projects

Long term timeframe

Covers multiple modes

Not fiscally constrained Updated per

ITS ArchitectureWorkshop Architecture Use in LRTP

Architecture output could be used directly in LRTP

Development of Long-Range Transportation Plan (LRTP)

Executive summary material/graphics from the architecture could be appropriate for the LRTP

The Regional Intelligent Transportation Systems (ITS) Architecture for the Kansas City metropolitan region is a specific regional framework for documenting and ensuring institutional agreement and technical integration for the implementation of ITS projects in the region. The documentation of the regional integration among transportation systems enables comprehensive planning and deployment activities while also supporting the sharing of information and coordination of activities that enables efficient and effective operations.

A Regional ITS Architecture is a Living ‘Document’

To remain useful, the architecture must be kept up to date Need a Plan to maintain it Required in the Rule/Policy:

▬ The agencies and other stakeholders participating in the development of the regional ITS architecture shall develop and implement procedures and responsibilities for maintaining it, as needs evolve within the region.

WHO will be responsible? ▬ Suggesting, approving, making changes

WHEN will updates occur?▬ How often, under what circumstances

WHAT will be maintained? ▬ Databases, website, documents

HOW will changes be managed?▬ Change management procedures▬ Version controls, naming conventions▬ Stakeholder notification

ITS ArchitectureWorkshop Session Outcomes

Identify how the regional architecture can support long range planning activities Describe how an architecture can be used to

program/budget ITS projects Describe the relationship between

architecture and systems engineering
