CDTC and its members have been active in providing significant support for community planning, transit service design, intermodal development, ITS deployment, demand management, and public participation. A regional vision is carried out at the local level to a degree that is exemplary (FHWA and FTA Certification Report, 2008)

. These big-ticket items in the recent update of New Visions include • Land use, transit, and environment: – Suburban town development centers; – Bus service expansion, BRT program with bus-oriented development; – Guideway transit system with transit-oriented development; – Travel demand management program; and – Clean, efficient vehicle program.

In addition to CDTC's core measures, "supplemental" performance measures are used to describe more specific, facilityrelated targets such as infrastructure and service. Supplemental measures include highway infrastructure, transit infrastructure, goods movement, transit service, and human service.

Obstacles One challenge that CDTC has been working on is using performance measures to link the congestion management process to the long-range planning process, thus aligning congestion management strategies with broader community goals. Reaching CDTC's community-developed vision depends on the successful outcome of many initiatives, including the New Vision principles, strategies, and actions.

By consolidating, disseminating, and archiving transportation-related data from stakeholder agencies in the corridor, the I-270 ICMS will • Provide improved information for a variety of purposes, including corridor transportation planning, management, traveler information, and emergency response; • Provide corridor transportation data fusion to allow an overall view of the corridor's transportation network; • Upgrade transportation data exchange capabilities of participating agency systems in the corridor as well as the region; • Upgrade the multimodal transportation systems management capabilities of the stakeholder jurisdictions for corridor transportation operations; • Upgrade traveler information dissemination capabilities at the corridor system level; • Upgrade corridor multimodal incident response and emergency preparedness capabilities; and • Provide the means to easily access corridor transportation data and produce corridor-level performance measures reports for decisionmakers. Funding for the initial planning of the I-270 ICM and the creation of a Concept of Operations, System Requirements, and Data Collection Plan has come from U.S.

The I-394 ICM initiative is looking to improve operations in the corridor by addressing problems associated with • Gaps in coordination between traffic and transit centers during "normal" and incident conditions; • Gaps in incident data on arterial networks; • Lack of traveler information for arterials and transit; and • Planning for special event congestion. The I-394 ICM project seeks to address these problems by • Providing traveler information across all networks and modes, including freeway, transit, and arterial travel times as well as park-and-ride availability; • Improving interagency communication and coordination, including improved incident management and detection on arterials, coordinated incident signal timing plans, and transit rerouting during incidents; and • Reducing congestion and improving trip reliability.

DOT under the national Urban Partnership initiative. The I-394 ICM can leverage this effort, which includes converting I-35W HOV lanes to MnPass HOT lanes; enhancing arterial traffic management on Hwy 13; increasing transit traveler information (park-and-ride lot availability, next bus arrival times, travel time comparisons)

is an NJDOT commitment to working with local municipalities to conduct a series of integrated land use and transportation planning studies. These projects are working to balance future development and redevelopment of each community with all aspects of transportation, including accessibility, mobility, safety, multimodality, and the natural environment of the corridor.

network) , bridges and roadways helps us not only to manage the demand on our mature transportation system but also pay for its improvements; and • Where our lively and diverse metropolitan region is transformed by a growth pattern that creates complete communities with ready, safe and close access to jobs, shopping and services that are connected by a family of reliable and costeffective transit services; and • Where technology advances move out of the lab and onto the street, including clean fuels and vehicles, sophisticated traffic operations systems to manage traffic flow and reduce delay and congestion on our roadways, advanced and accessible traveler information that allows us to make informed travel choices, and transit operational strategies that synchronize fare structures, schedules and routes to speed travel to our destinations; and • Where we have a viable choice to leave our autos at home and take advantage of a seamless network of accessible pedestrian and bicycle paths that connect to nearby bus, rail and ferry services that can carry us to work, school, shopping, services or recreation; and • Where we lead and mobilize a partnership of regional and local agencies, businesses and stakeholders to take effective action to protect our climate and serve as a model for national and international action; and • Where our transportation investments and travel behaviors are driven by the need to reduce our impact on the earth's natural habitats, and • Where all Bay Area residents enjoy a higher quality of life.12 Using this vision, T-2035 incorporates key changes and trends that are on the horizon, such as climate change, volatile oil prices, an aging population, rising construction costs, and the uncertainty of federal transportation funding.

Performance Measures The performance objectives established for the Transportation 2035 report are derived from the three Transportation 2035 goals: economy, environment, and equity. They were intended not to stand as simple outcomes for the long-range transportation plan but to provide a roadmap for testing scenarios.
