SB1 Regional Studies

In 2018, SJCOG began several new  studies to both translate the 2018 Plan into actions that support sustainable development and to prepare for the upcoming 2022 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS). Taking this vital step will further the on-going work of SJCOG and its member agencies in reducing greenhouse gas emissions through transportation investment and complimentary land use development. These planning studies are funded directly by Senate Bill 1 (SB1), The Road Repair and Accountability Act of 2017.

SCS Implementation Study

The purpose of the Sustainable Communities Strategy (SCS) Implementation Study and South Stockton Case Study is to establish a path for achieving SJCOG's SCS goals through identifying both challenges and opportunities countywide.  The case study, with an emphasis on planning gaps  in one of the region's communities of concern in South Stockton will showcase how regional and local partners can work together to overcome challenges associated with reaching regional goals.  It will provide a template for use across the region. There will be opportunity for member agencies and local partners to provide input.

Climate Adaptation and Resiliency Study

The Climate Adaptation and Resiliency study will seek to identify the transportation assets within San Joaquin County that are most vulnerable to disruption caused by extreme climate events. This study will determine the risks and consequences to identified key transportation assets, as well as prioritize strategies to strengthen system resiliency.    Some of the risk factors that this study will consider include weather events, extreme heat, flooding, sea-level rise, and other relevant data. This study is the first step in SJCOG's commitment to addressing federal requirements incorporated into the recent RTP guidelines related to improvement of the resiliency and reliability of the transportation system.

Public Health Impact Analysis - Update and Small Area Study

The 2018 RTP/SCS included a county level pilot study to compare the public health impacts of three planning scenarios. This pilot study predicted physical activity minutes, as well as average Body Mass Index (BMI) and poor health. The SB 1 planning study will build upon the pilot by adding new health indicators, such as diabetes and cardiovascular disease rates. To better inform future infrastructure investment and land use decisions, a small area study will test built environment scenarios to learn their effects on health and social equity outcomes.

Mega-Region Economic Modeling Pilot

The Northern California Mega-Region includes the nine-County San Francisco Bay Area, plus the Sacramento Region to the north, the Monterey Bay Area Counties to the south, and the three northern San Joaquin Valley Counties.  In 2018 the Association of Bay Area Governments (ABAG) added several counties outside of their nine-County region to their regional economic modeling program, including the counties of San Joaquin, Stanislaus, and Merced.  SJCOG, in conjunction with the Center for Business & Policy Research at UOP, will be exploring this model’s use in refining population and employment forecasts.  The pilot will also look at estimating the economic effects of varying transportation investment policies.

Integrated Ticketing Feasibility Study

With the support of SB1 funding, SJCOG will assess the feasibility of implementing integrated ticketing on all public transit providers in San Joaquin County, including the San Joaquin Regional Transit District, Lodi Grapeline, Manteca Transit, Tracy Tracer, Escalon eTrans, Ripon Blossom Express, and the Altamont Corridor Express. SJCOG will lead the study as the prime investigator with input from a transit operator working group and assistance from a technical consultant. The goal of this program is to encourage more people to use public transit in San Joaquin County by offering a user-friendly trip planning and mobile ticketing application that enables seamless transfers between all 7 transit districts. SJCOG will reach this goal by partnering with an experienced provider to develop an integrated ticketing mobile app.
