Transportation Network Concepts

Vea esta página en español.

Community input is critical to creating a plan that reflects the values, needs, and interests of our region’s residents and businesses. 

In spring 2018, SANDAG received valuable community input that identified several transportation and quality of life priorities, including congestion relief, climate change and the environment, emerging technologies, healthy communities, and housing, jobs, and the economy. These priorities were used to develop three network concepts for the 2019 Regional Plan – Shared Mobility, Connected Corridors, and Policy Possibilities – that were available for review and comment throughout October 2018. The network concepts were a starting point for SANDAG to hear from communities about transportation needs and tradeoffs across our region. Review the summary of public input (English | Español) presented to the SANDAG Board of Directors on November 16, 2018.  

Public input gathered on these concepts is being used to develop draft scenarios for the public and SANDAG policymaker review and input later this winter. Then, in early 2019, the SANDAG Board of Directors will select a preferred scenario that will form the core of the 2019 Regional Plan and be evaluated in its Environmental Impact Report.

Overview of the Network Concepts 
Each network concept includes a mix of projects, technology, programs, and policies that address transportation needs for people and goods in our region through 2050. The network concepts were developed with intent to: provide travel choices, manage demand and enhance the transportation system, support goods movement and the economy, maximize investments in existing transportation infrastructure, and consider impacts on social equity, the environment, and public health.

Each concept includes a fiscally constrained vision for our region’s future transportation network, based on reasonably anticipated levels of funding from a variety of local, state, and federal revenue sources, which were reviewed with the SANDAG Board of Directors. As in past plans, the majority of funds are distributed to local transit agencies (MTS and NCTD) and Caltrans for operations and maintenance needs, and to local jurisdictions for street and road improvements. Also, funds from some sources can only be used for certain projects; for example, money from the Federal Transit Administration can only be invested on public transportation projects. The remaining funds are considered “flexible”. The network concepts differ largely in their use of flexible funding and consider tradeoffs in which projects are built, transit routes are operated, and which programs are serviced. Additionally, as revenues are received over time, the concepts include phase years – 2025, 2035, and 2050 – for when different projects, programs, or policies will be implemented.

  Network Concept A:
Shared Mobility
      Network Concept B: 
Connected Corridors
      Network Concept C:  
Policy Possibilities
 
                 
Emphasizes more transit connections through earlier delivery, increased frequency, and additional services and routes. Flexible funding is focused on investments to support transit, and with earlier delivery of a system of Rapid routes (community and major corridors). This concept also includes pricing on Express Lanes for solo drivers and two-person carpools.  
      Emphasizes major corridor improvements for highway and transit projects and concentrates on completing a connected system of Managed Lanes. Flexible funding is focused on Managed Lanes/highway projects, and Managed Lanes are priced for solo drivers and two-person carpools. Similar to the I-805 carpool lanes, these lanes could support Rapid transit, carpools, vanpools, and electric vehicles; and automated and connected vehicles in the future.        Emphasizes actively managing out transportation network through new technologies, policies, and programs. Flexible funding is focused on transit with reduce fares and mobility management programs/ incentives. Other considerations include tolled carpool and Managed Lanes for all vehicles, parking pricing, pooled ride incentives, adoption of automated and connected vehicles, electric vehicle charging infrastructure and purchase incentives, and smart intersections.

Performance measures
Each network concept is evaluated using performance measures to analyze how the network could help to provide access to jobs and higher education, reduce greenhouse gases, and support public health and the regional economy. A social equity analysis also is performed for each network to assure that the benefits and burdens of the plan are shared equitably.

Performance measures for the 2019 Regional Plan were developed through thoughtful and extensive collaboration with the public, stakeholders, SANDAG Policy Advisory Committees and Working Groups, as well as an industry-led Peer Review Panel. The final performance measures were approved by the SANDAG Board on March 23, 2018. Performance measure results for the network concepts are based on 2035 population and transportation policies, programs, and projects.  

The 2019 Regional Plan development process
In fall 2017, the SANDAG Board refined the vision, goals, and policy objectives, and accepted use of the existing Unconstrained Transportation Network and the list of ranked projects from 2015 as a starting point for developing the 2019 Regional Plan. The SANDAG Board approved performance measures in March 2018 and, in June 2018, provided direction on the level of funding to use for the 2019 Regional Plan. 

In spring 2018, the public provided input on several transportation and quality of life priorities, which helped inform development of three draft transportation network concepts. Public input gathered on these network concepts throughout October 2018 is being used to help develop draft network scenarios for further review and input later this winter. Then, in early 2019, the SANDAG Board will select a preferred scenario that will form the core of the 2019 Regional Plan and be evaluated in its Environmental Impact Report.
