Project Summary

Infill rail transit stations are added along an already built line or set of lines between existing stations. Such stations are relatively low cost because they take advantage of existing lines and services. They can support additional ridership in the short term by increasing station accessibility and also may support growth in the form of added economic activity, infill development, or redevelopment and revitalization, further increasing accessibility and ridership. In turn, growing ridership may support higher levels of service (larger trainsets, more frequent service) on the lines served. Existing activity centers and neighborhoods may be strengthened by the increased accessibility an infill station provides. New housing and economic development opportunities around infill stations can be substantial if the station location is well chosen, local government policies and community members support growth, and existing owners can expand or developers can secure suitable sites for new construction. On the other hand, economic opportunities can be limited if there is community opposition to growth, local policies are impediments, or there is limited interest in investing in the area from the business and development community. Unwanted neighborhood changes including displacement due to rising property values may be an issue. Transportation level of service plays a role; lines with limited service will offer lower development potential than lines with high levels of service. Also, because adding a station involves added deceleration, dwell time, and acceleration time to existing trips, there is a small negative impact on existing riders due to the added stop. For this project, researchers will examine the costs and benefits of infill transit stations. The team considers transport capital, operating, and maintenance costs, costs to existing riders of additional trip duration due to added stop(s), and benefits to existing and new riders of improved accessibility (reduced travel time and costs) from both origins and to destinations. This project further considers economic development potential and social environmental impacts of infill stations. Researchers present evidence drawn primarily from U.S. experience with infill transit stations in the Boston, Chicago, Washington, and San Francisco Bay Area metropolitan areas. Finally, the research team applies the evidence to assess the potential cost and benefits of an infill station in the Shinn Station area in the East Bay near the Union City and Fremont, CA, border, linking Altamont Corridor Express (ACE) and Bay Area Rapid Transit (BART) services.

Assessing and Addressing the Mobility Needs of an Aging Population

Project Summary

By 2030 the older adult population in California is expected to nearly double to over 8.6 million people. Many if not most older adults will reduce and eventually stop driving for medical and non-medical reasons, which in turn can impact mental health and activities including accessing needed medical care. In order to plan for these mobility changes and to support healthy aging in California, this proposed project will build upon work that the research team has conducted in California (funded by National Institute of Health and National Highway Traffic Safety Administration) and nationally with members from the Center for Disease Control and Prevention’s Healthy Aging Network (funded by the Federal Transit Administration) to understand the mobility needs of older adults in California. A comprehensive literature review is proposed followed by a representative survey of the aging adult population to assess: (i) mobility needs, (ii) impact of emerging technology on mobility, and (iii) impact of neighborhood characteristics on mobility. Through contracting with established survey companies, the team has conducted successful surveys of representative samples of the California population.

Project Summary

The population of California is aging as life expectancy increases and birth rates decline. Projections from the U.S. Census Bureau show that by 2030, the number of seniors in California will increase to 10.6 million, almost a quarter of the state population. Closely related, but far less studied, is the aging of the workforce as the population ages and many older people delay retirement either because they enjoy working or depend upon earned income to meet their needs. From a recent low of less than 6 percent of the working population, the share of employed Americans who are older than age 60 has climbed to over 10 percent of all workers and is projected to exceed 13 percent of the employed population by the middle of the next decade. The objective of this study is to determine, using data from the California Household Travel Survey, whether there is a relationship in California between mobility (e.g. access to an automobile, the physical ability to drive, living in transit-accessible locations or proximate to business centers, and working from home) and delayed retirement. Delayed retirement will be measured as those who remain in the paid workforce past age 60. Specific research questions that will be explored include: Are the elderly who continue to work those living closer to jobs and transit routes and are they more able to drive or travel by public transit than those who have retired? Longitudinal trends will be examined using one earlier CHTS. While important statistical associations are expected to emerge from this analysis, they will not tell the whole story because it is difficult to disentangle cause from effect. Do people continue to drive or live near transit so that they can go to work or do they continue to go to work because they are able to drive or use public transit? To explore subtle causal relationships, the research team also will conduct interviews of older workers and recent retirees. The interviews will enable researchers to complement the statistical findings with insights from qualitative descriptions of personal decision making about work, residence, and commuting. The results of the qualitative analysis will allow useful interpretations of and lend confidence to the results of the quantitative analysis.

Regional Industrial Land Preservation: Perspectives from San Francisco Bay Area Cities on a Priority Production Area Program

Project Summary

Many regions in California have prepared long-term plans for goods movement, recognizing the need to develop freight facilities to accommodate the transformation and growth of logistics in the state. Yet, for most, planning for industrial lands – and related jobs –is an afterthought. The Metropolitan Planning Commission and the Association of Bay Area Governments (ABAG) have thus decided to enact a new program that allows jurisdictions to prioritize industrial uses (the Priority Production Areas or PPAs). PPAs will then be included in the region’s Sustainable Communities Strategies. Although ABAG’s Executive Board adopted the program in early 2017, and it is mentioned in the 2040 Plan Bay Area, the program has not yet been developed. This translational project will help the Bay Area’s regional agencies develop the program. Building on program guidelines suggested by the recent “Goods Movement and Industrial Land Supply” study (funded by Caltrans), this project will interview and convene UC, regional agency, local jurisdiction staff, and economic development organizations to discuss and develop potential guidelines for designating PPAs. UC-Berkeley will also assist by identifying possible incentives and other implementation mechanisms and providing data and analysis to assist jurisdictions interested in participating in the program.

Encouraging Mode Shift from Truck to Rail for California Produce

Project Summary

The movement of California goods is one of the largest employment generators within the state and is critical to both the structural health of the economy and the physical health of its citizens. However, the goods movement sector is subject to market failures that may result in suboptimal modal shares, in particular an excess of truck traffic some of which would ideally be diverted to rail. While opportunities for modal shift are limited within the state, there are significant possibilities for California exports. Examining the agricultural sector, California is one of the largest producers of perishable produce in the world and a majority of this produce leaves the state on a truck, despite the fact that rail dominated the market through the mid-1970’s. Significant inertia exists today among the grower-shipper- buyer network that has frozen in place the domination of the trucking industry among perishable produce, even though rail movement would reduce social cost in many cases. While the private sector is unlikely to invest in a modal shift given the historically low fuel prices, it is possible that there is an opening for a public-private partnership (PPP) that could provide a gentle push for change. This project will build on the initial work from the “Rail and the California Economy” project and explore the possibility of using public initiatives—including capital investment, risk sharing, subsidy, and other interventions—to support new rail infrastructure for the perishable produce industry. Specifically, the report will review the current state of affairs in two major growing regions, the Salinas Valley and the southern Central Valley, and analyze how goods move and the benefits of a modal shift to rail. The report will then identify public-private partnerships that might promote a shift to realize these benefits. Additionally, if time permits the project may review an existing PPP involving rail, the reconstruction of the Colton Crossing in southern California and the public benefits associated with its completion.
