Do Compact, Accessible, and Walkable Communities Promote Gender Equality?

Abstract

Directing growth towards denser communities with mixed-use, accessible, and walkable neighborhood design has become an important strategy for promoting sustainability, but few studies have examined whether compact development strategies could help reduce within-household gender disparities in spatial behavior by increasing accessibility. The research team analyzed the spatial behavior of heterosexual married couples in Southern California based on the 2012 California Household Travel Survey and found that households living in areas with greater regional accessibility and neighborhood walkability have smaller, more centered, and more compact activity spaces overall compared to households in less compact areas, and that married pairs living in more accessible areas have greater equality in the size and centeredness of their activity spaces. Results support the hypothesis that compact development provides married couples greater flexibility in how they divide household out-of-home activities by making destinations more convenient. Future research and planning efforts should carefully consider which aspects of compact, accessible development are most effective for a given local context.

Lessons from Transportation Agency Participation in Regional Conservation Initiatives

Abstract

Transportation agencies often struggle to balance wildlife habitat preservation with infrastructure development, leading to challenging approval processes for transportation projects in sensitive environments. The Endangered Species Act (ESA) requires that public and private project developers mitigate any harm to endangered species and receive a permit from the U.S. Fish and Wildlife Service (FWS). Transportation projects are typically permitted individually, which can be time-consuming and expensive. The ESA’s Regional Habitat Conservation Plan (RHCP) is a tool to help agencies protect the environment while streamlining the permit process for infrastructure development. By addressing environmental issues on a regional scale, RHCPs allow one permit to cover projects in multiple jurisdictions for up to 75 years. RHCPs are popular with transportation agencies, but they require unique collaboration with other stakeholders. Researchers at UCLA examined 21 RHCPs to better understand the nature of these institutional collaborations and ways to maintain them over time

Design and Implementation of the Enhanced Fleet Modernization PlusUp Pilot Program: Lessons Learned from the San Joaquin Valley and South Coast Air Districts’ First Year of Operation

Abstract

In order to reach California’s ambitious air quality and climate change mitigation goals, the state needs a cleaner and more efficient transportation system. Replacing older, heavily-polluting cars with cleaner, more fuel-efficient vehicles is a first step. To help with this effort, the California Air Resources Board introduced the Enhanced Fleet Modernization Program (EFMP) Plus-Up pilot program in June 2015. EFMP Plus-Up increases incentives for for low- and moderate-income households to retire and replace older and inefficient vehicles, providing up to $9,500 toward the purchase of plug-in hybrids or electric vehicles.The program was implemented as a pilot phase in the San Joaquin Valley Air (SJV) Pollution Control District and the South Coast Air (SCA) Quality Control District. Researchers at UCLA used program data from these districts to better understand the initial impact of the program

Can Smog Repairs Create Social Justice? The Tune In & Tune Up Smog Repair Program in the San Joaquin Valley

Abstract

High levels of car travel contribute to poor air quality in California’s San Joaquin Valley (SJV), but car usage is unlikely to decline in the near future, as the region is not dense enough to support an effective transit system as an alternative for personal travel. The region’s air quality presents a significant environmental justice concern given the high percentage of minority and low-income residents in the Valley. To combat the harm caused by high-emitting vehicles, the SJV Air Pollution Control District and the nonprofit Valley Clean Air Now (Valley CAN) started the Tune In & Tune Up (TI&TU) program, providing SJV residents with free emission testing and vouchers for smog repair at a series of publicly-held events across the Valley. Since 2012, the program has distributed more than $12 million in redeemed vouchers.UCLA researchers evaluated the TI&TU program’s efficiency, environmental, and equity outcomes, and considered its relevance for expansion and adoption in other regions. Their findings are not only relevant to regional and state policymakers in California’s transportation planning and air quality fields, but to practitioners and scholars studying policies to support transportation equity and environmental justice more broadly

Falling Transit Ridership: California and Southern California

Publication Date

January 1, 2018

Abstract

In the last ten years transit use in Southern California has fallen significantly. This report investigates falling transit use. We define Southern California as the six counties that participate in the Southern California Association of Governments (SCAG) – Los Angeles, Orange, Riverside, San Bernardino, Ventura and Imperial. We examine patterns of transit service and patronage over time and across the region and consider an array of explanations for falling transit use: declining transit service levels, eroding transit service quality, rising fares, falling fuel prices, the growth of Lyft and Uber, the migration of frequent transit users to outlying neighborhoods with less transit service, and rising vehicle ownership. While all of these factors probably play some role, we conclude that the most significant factor is increased motor vehicle access, particularly among low-income households that have traditionally supplied the region with its most frequent and reliable transit users.

Shared Mobility Policy Briefs: Definitions, Impacts, and Recommendations

Abstract

In 2017, researchers from UC Berkeley’s Transportation Sustainability Research Center and the Institute of Transportation Studies produced eight policy briefs on shared mobility. Shared mobility – the shared use of a vehicle, bicycle, or other travel mode – services are experiencing rapid growth and expansion. This is, in part, due to the launch of innovative business models across California, and their use of the smartphone as a way to enable on-demand transportation options. There is a need to clarify emerging terms and best practices for policymakers amidst the fast-paced developments of the field. Fluency in data-sharing opportunities and standards, funding options, and equity considerations will be needed to implement flexible, forward-thinking policies. These topics are covered in the briefs that follow. Each brief includes a presentation of research findings, a description of the research approach, and recommendations for the California Legislature. Policymakers and legislatures can refer to these briefs for digestible explanations of research findings and suggestions of ways to apply research to improve California’s transportation system
