Creating a Regional Program for Preserving Industrial Land: Perspectives from San Francisco Bay Area Cities

Roach, Emily
Chapple, Karen, PhD
2018

Industrial land plays a vital role in supporting the regional economy in the San Francisco Bay Area. It provides the operating space and support services for export sectors and other important local clusters, maintains linkages between businesses and sustains a local supply chain, provides diverse employment opportunities for people with a broad range of skills (including those with lower educational attainment), and supports a high share of middle-wage job opportunities. However, the Bay Area’s current inventory of industrial land (and associated jobs) is at risk due to increasing...

MPO Planning and Implementation of State Policy Goals

MPO Planning and Implementation of State Policy Goals evaluates California metropolitan planning organizations’ regional transportation plans and sustainable communities strategies and looks at the relationship between MPO plans and what is actually funded through transportation improvement programs.

Flexibility in California Transportation Funding Programs and Implications for More Climate-Aligned Spending

Segal, Katie
Elkind, Ethan
Lamm, Ted
2021

Flexibility in California Transportation Funding Programs and Implications for More Climate-Aligned Spending examines key features of the legislative authority for transportation planning and finance in California, including local option sales taxes for transportation, and assesses the amount of flexibility that current laws and practices allow for reprioritizing projects as problems and priorities change.

Review of Statewide Transportation Plans for California

Deakin, Elizabeth
Chow, Chun Ho
Son, Daisy
2021

California has adopted ambitious goals for its transportation systems. The state has pledged to reduce greenhouse gas(GHG) emissions by 40 percent compared to 1990 levels and by 80 percent by 2050, and has also committed to achieve carbon neutrality by 2045. With transportation a major emitter, substantial changes in transportation vehicles, fuels, operations, and user choices must be achieved to meet these goals. As pressing as climate change goals must be, other goals remain important. California has pledged to maintain its transportation infrastructure in a state of good repair, provide...

The Producer Surplus Associated with Gasolne Fuel Use in the United States

Estimating the producer surplus – the revenue above the average long-run cost – is an important part of social cost-benefit analyses of changes in petroleum use. This paper estimates the producer surplus associated with changes in gasoline fuel use in the United States, and then applies the estimates of producer surplus to two kinds of social cost-benefit analyses related to petroleum use: (1) estimating the wealth transfer from consumers to producers as a result of policies that affect oil use and oil imports to the US, and (2) comparing the actual average cost of gasoline with the...

New Metrics for Measuring Academic Research Outside the Ivory Tower

Levine, Kendra K.
2019

The need to demonstrate the value of research programs is critical for funding sustainability, particularly in the 21st century where research funding is rarely guaranteed beyond the life of a single project. After the great economic crash of 2008 many research programs have also diversified their funding portfolios, which means cultivating new relationships with funders and potentially different objectives of research projects. Measuring the impact of academic research outside academia is critical to providing a holistic view of a research program, but the methods to do so are still being...

User Acceptance and Public Perception Regarding Automated Driving Systems

Motamedi, Sanaz
Wang, Pei
Chan, Ching-Yao
2018

Fully Automated Driving System (ADS) is one of the most innovative and fundamentally disruptive changes in transportation. This technology has the potential to resolve or mitigate current transportation problems, including reducing traffic accidents, congestion, energy consumption, and pollution. However, the extent of these impacts will depend heavily on public perception and widespread adoption of ADSs. To gain a better understanding of user acceptance and public perception related to ADS, extensive interviews were conducted with Tesla end-users who have experience using partial ADS (i.e...

Electric Bike Use in China and Their Impacts on the Environment, Safety, Mobility and Accessibility

Cherry, Christopher
2007

Chinese cities have a long legacy of bicycle use due to relatively low incomes, dense urban development, and short trip lengths. Because of tremendous economic growth resulting in increased motorization and spatial expansion of cities, trips are becoming longer and more difficult to make by bicycle. As a result, electric powered twowheelers have risen in popularity over the past five years. Touted as environmentally friendly vehicles, they are capable of traveling 450 kilometers on a single charge and emit zero tailpipe emissions. However, many cities are banning electric twowheelers from...

The Environmental Impacts of Logistics Systems and Options for Mitigation

Sathaye, Nakul
Li, Yuwei
Horvath, Arpad
Madanat, Samer
2006

This paper presents a discussion directed at determining the most progressive options for shifting the freight logistics industry towards having more sustainable-oriented goals. The authors first discuss transportation sustainability and the concept of green logistics. This is followed by a discussion on externalities resulting from vehicle emissions and indirect environmental externalities. The problem of environmental externalities is then examined, with focus on emissions and other related data. The authors then examine options for reducing environmental externalities. They discuss...

Performance Measures for Complete, Green Streets: A Proposal for Urban Arterials in California

Sanders, Rebecca
Macdonald, Elizabeth
Anderson, Alia
2010

The California Department of Transportation (Caltrans or “Department”) manages more than 15,000 miles of state highways, ranging in scale and function from local streets to interstate highways. Historically, Caltrans has been governed by the principles of highway engineering, which focus on providing mobility to motorized vehicles. Over the past decade, however, the Department has joined in a national movement to better incorporate non-motorized transportation and community-level outcomes into its transportation decision-making framework, embodied by the approach known as "Complete Streets...
