Project Summary

Inner-city youth often walk to school and are likely to encounter unsafe streets with higher proportions of pedestrian-automobile crashes. Despite Vision Zero and Safe Routes to School programs, they remain disproportionately represented among traffic fatalities, which are the highest in a decade. But the idea of safe streets goes beyond pedestrian-traffic relationships. As one study of inner-city fifth graders in Los Angeles found, “dangers in their social milieu are a much greater concern for them than the physical milieu, which the walkability research typically emphasizes.” These social dangers influence youth’s choice to frequent traffic-heavy streets like those included in Vision Zero’s high-injury network, as these arterials are perceived safer for walking than more quiet but desolate residential streets. Thus, youth’s urban paths to and from school are informed by “hot spots” (where crime and crash data indicate danger) as well as “safe spots” (where data indicate safety from crime). Therefore, enhancing safety among inner-city youth requires attention to both physical and social relationships. The researchers will work with youth (aged 12-15) to study their journey from school to after school activities in the LA neighborhood of Westlake. This neighborhood falls within the city’s high injury network as defined by the Los Angeles Department of Transportation (LADOT) Vision Zero Plan and includes two Safe Route to School areas. The researchers have built strong community partnerships over a two-decade long history of working in this neighborhood. While their preliminary work with youth in Westlake has found traffic speed to be a top concern among middle-schoolers, youth also carry mental maps of local “sidewalk ecologies” that include bus stops, lighting, social activity, shade, unhoused residents, and vendors, among other factors that shape their routes. This concept of “sidewalk ecology” will be used to emphasize the interaction of both positively and negatively perceived social and physical features that affect mobility. Together with their community partner, the HOLA after-school program, the researchers will prepare walking audits, perform cognitive mapping, document sidewalk ecologies, and conduct follow-up youth interviews. The research will be supported by LADOT pedestrian safety data serving as reference points in mapping the varied routes taken by study participants. By thoroughly documenting and interpretating youth route choices and experiences this research will provide insights into how neighborhood youths perceive streets, and how planners and policymakers can make them safer.

Project Summary

Work trips are critical to transit planning and help determine the corridors served and the levels of transit service available. During the COVID-19 pandemic many office employees were able to telework, while millions of others — largely people with low incomes, people of color, and essential workers — still commuted to jobs every day. While there are a plethora of studies regarding changes in commute patterns during the pandemic, there is considerable uncertainty as to the long-term structural shifts in commuting and what these changes mean for public transit systems and equitable access to jobs. This research quantifies changes in the transportation system and equity implications of emerging teleworking patterns since the onset of COVID-19. In its 2022 Equity Action Plan, the US Department of Transportation noted two critical gaps in equitable access to jobs: 1) travel time burden and 2) travel cost burden. The researchers will examine how the COVID-19 pandemic affected both measures for disadvantaged populations using the Consumer Expenditure Survey and the American Time Use Survey for 2019 and 2021. The researchers will quantify disparities in job access before and after COVID-19 and the factors influencing them through a thorough literature review, descriptive analyses, and qualitative interviews. Descriptive analysis will use data from multi-wave online surveys conducted by UC Berkeley and Resource Systems Group as well as passively tracked smartphone data across the United States. Qualitative interviews will be held with California public transit agencies and Metropolitan Planning Organizations regarding the implications of the changes in commuting due to COVID-19 on their operations and future investment decisions.

Project Summary

Achieving a near-zero CO2 transportation system within California will be extremely challenging but is needed to reach the state’s goal of carbon neutrality by 2045. The transition will require a revolution in the way transportation services are provided, and in the policy choices needed to make these technologies economically viable. California is a world leader in low-carbon transportation policies including 100% zero emission vehicle (ZEV) mandates, vehicle and infrastructure incentives, low-carbon fuel standards, and others. However, these are likely not enough to achieve net zero goals by 2045, as highlighted in the May 2022 Draft Scoping Plan by the California Air Resources Board (CARB). While the Scoping Plan will serve as an important planning tool, the state would also benefit from additional analysis of other national strategies, especially from leading European countries and the European Union (EU), that can be applied to California. Strong sustainable transportation policy action across the United Kingdom, Germany, France, Sweden, and other countries are worthy of investigation both as sources of innovative and alternative policies but also as potential synergistic approaches to what is already underway here. This project will conduct an analysis of low-carbon transportation policies in Europe (focused both at the EU-level and among member countries) and in California, including recent and planned policies, with a particular focus on ZEVs. The most important European policies will be compared to existing and planned policies in California to gain insight into how California could adapt some European strategies in its quest for a carbon-neutral future. Emphasis will be on road vehicles (light-duty vehicles and medium/heavy duty trucks and buses), but some attention will also be given to aviation, shipping, and rail. Areas of analysis will include vehicle and fuel-related regulatory policy, financial and fiscal policies such as incentives and feebates, as well as direct investments (e.g., in infrastructure, information/education, etc.). The analysis will review transportation greenhouse gas (GHG) emission targets, progress on reducing GHG emissions from different transportation modes, current strategies, policies, and their impacts. It will also examine the analysis and modeling of current and future trends, policy impacts, and gaps.

Project Summary

The last five years in California have seen annual averages of over 3,800 fatalities, nearly 15,900 serious (but not fatal) injuries, and over 233,100 minor injuries from vehicular collisions. These collisions disproportionately occur in marginalized neighborhoods and victimize people from socioeconomically marginalized groups, including people with disabilities. Despite the physical injuries and mental traumas that collisions can inflict upon victims, loved ones, emergency responders, and even otherwise unrelated bystanders, little is known about the effects of collisions on their travel behavior, such as frequency of travel and mode choices. Hypothetically, decreases in travel frequency could significantly harm socioeconomic equity, as victims or loved ones who travel less may participate less in the economy as workers or consumers, and these effects may be amplified for people with disabilities, who already face disadvantages with respect to access and mobility. Additionally, changes in mode choices, especially away from public or active transportation toward private vehicular transportation, may undercut Caltrans’s connected goals for road safety, equity, and greenhouse gas emission reduction in the California Transportation Plan 2050, Caltrans 2020-2024 Strategic Plan, and California 2020-2024 Strategic Highway Safety Plan. This study aims to answer: (1) How do experiences with collisions or near misses affect travel frequencies and mode choices among people with disabilities? (2) Do experiences with collisions or near misses correlate with people being less likely to use certain vehicular modes (e.g., driving, riding as a passenger, or using taxis, ridehailing services, or paratransit) compared to those without such experiences? To answer these questions, this project will use informal interviews, focus groups, and a survey. The research team will work with community-based organizations (CBOs) throughout California, especially those that advocate for people with disabilities, who are disproportionately vulnerable to collisions, as well as those which advocate for road safety in socioeconomically marginalized communities. Informal interviews and focus groups with representatives from those CBOs will help the researchers better understand issues facing people experiencing collisions and near misses, what questions may be too sensitive or problematic to ask such people, and policy challenges. Following these discussions, the research team will survey adults in California about their current frequencies of using different modes of transportation, firsthand or secondhand experiences with collisions or near misses, the extent to which those experiences have influenced their mode choices, their neighborhood type, and demographic, socioeconomic, and disability status. Findings will contribute to formulating policies for roadway safety, transportation equity, and greenhouse gas emission reduction.

Project Summary

Since 2017, there has been massive growth in micromobility trips (i.e., trips taken by electric bike-share and scooter-share). To understand the extent to which micromobility services such as bike-share and scooter-share are replacing driving, this project explores the trip-chaining patterns of micromobility users. The project uses travel diary data collected from micromobility users in 48 cities across the US. Results point to a considerable portion of car owners leaving their cars at home when using micromobility, suggesting that, for a subset of users, micromobility can form part of a car-free or car-light day of travel, despite having a car available.

Project Summary

California faces major policy challenges that stem in part from decades of planning for automobility. For one, the state cannot meet its ambitious decarbonization targets without reducing greenhouse gas (GHG) emissions from the transportation sector, which produces nearly 40 percent of California’s emissions. Substantial reductions in vehicle miles traveled (VMT) are likely needed to meet the state’s climate change goals. In addition, the state is mired in a historic housing supply and affordability crisis. It ranks 49th in the United States in housing units per capita. It needs millions more units to meet demand, including 1.3 million more affordable rental units, according to one estimate. Transit oriented development (TOD), with denser housing around transit hubs, can solve both challenges—reducing driving and producing more housing. However, TOD is often difficult to achieve in practice. One frequently cited roadblock to TOD is the environmental review process under the California Environmental Quality Act (CEQA), which can add considerable time, cost, and uncertainty to TOD plans and developments. There have been numerous attempts to exempt or provide a streamlined CEQA review process for TOD projects, including through Senate Bill (SB) 375 projects (and infill developments generally). These efforts are often “criticized for layering on so many project level restrictions that no developments succeed in meeting all the eligibility requirements.” However, there is limited empirical research on how frequently the provisions have actually been used or how successful they have been at streamlining the entitlement process for TOD projects.

This research project will explore the use and effect of the two CEQA streamlining provisions in SB 375 for TOD projects. One provision exempts qualifying transit priority projects (TPPs) from CEQA review entirely (Public Resources Code § 21155.1). The other provision streamlines CEQA review for qualifying TPPs (Public Resources Code § 21155.2). The researchers will catalog projects that have utilized these provisions, identify projects that likely could have taken advantage of SB 375 CEQA streamlining but did not, and interview planners and developers involved with a subset of both sets of projects. The outcome will be an in-depth exploration of how much SB 375 streamlining actually helps reduce the time, cost, and uncertainty of permitting TOD projects, and how it could be improved to better meet those goals.

Project Summary

Reducing vehicle miles traveled (VMT) is a key plank of California’s climate and broader transportation policies. The draft Scoping Plan Update from the California Air Resources Board calls for a per capita reduction in VMT of at least 22% from 2019 to 2045, and the state’s regions have enshrined VMT reduction targets in their Sustainable Communities Strategies. These reductions, however, are unlikely to be achieved without a reduction in the physical space—roadways and parking—allocated to motor vehicles. Just as parking and highway expansion induce more vehicle travel, capacity reductions can reduce it and also lock in place VMT reductions achieved through improved transit and active transportation facilities. The research team will consider if, how, where, and to what extent California local governments are reducing road and parking capacity. Such reductions are likely to be relatively small-scale to date, and so the researchers will examine three policy areas where embryonic capacity reductions are most likely to have occurred: (i) the conversion of existing garages to Accessory Dwelling Units, leading to a reduction in parking for the principal residence; (ii) elimination of parking and/or travel lanes to create space for bicycling infrastructure; and (iii) conditions of approval for development projects under the new vehicle miles traveled standard following SB 743.

Project Summary

Vehicle miles traveled (VMT) is a well-accepted measure of the amount of travel taking place on a transportation system and thus, that system’s climate impacts and sustainability characteristics. California Senate Bill (SB) 375 establishes a process for setting regional-level targets to reduce VMT, which necessitates incorporating VMT-based analysis into transportation planning and modeling in practice. The issue is whether VMT needs to be further classified into “types of VMT” that can be incorporated into the process to provide more sensitive policy analysis. Trips differ in both their purpose and in the mode or vehicle used, and consequently, VMT can be viewed as better or worse for economic productivity and sustainability based on these characteristics. For example, some car trips can be accomplished with web-based devices. Little research has pursued this notion for policy-making purposes. Using available data on trip purposes, and on vehicle mixes (in terms of fuel usage and environmental impact) used for trips, productivity-based indices can be developed to properly assess the environmental/energy impacts of the VMT associated with broad classes of trips.

This project utilizes various data sources and an existing transportation system planning and analysis model (for a selected case study network) to develop methods for identifying and prioritizing potential VMT categories. Researchers will then use this information to evaluate the impact of different policies. This initial study will also serve as a trial for larger studies to evaluate system-wide policy implications. VMT category-based pricing, subsidy, taxation and land-use policies can be tested in selected network case studies. One simple example would be taxing VMT from electric vehicles less than gasoline powered vehicles.

Right-sizing Transportation Infrastructure to Reduce Vehicle Miles Traveled

Project Summary

Most of California’s success in reducing transportation emissions over the last 20 years can be attributed to improvements in vehicle efficiency and the adoption of lower-carbon fuels, particularly electricity. California must also reduce vehicle miles traveled (VMT) in order to meet critical climate goals and to enjoy the many co-benefits of reduced driving, such as improved air quality, safety, and public health. Increasing active transportation and transit options are two key strategies that California regions are using to try to reduce VMT, but to date, these projects have not been able to significantly cut VMT. One potential explanation is induced travel demand. Just as adding a highway lane reduces congestion and travel times and thereby induces more people to drive, the same outcome may occur when rapid transit and bike facilities are constructed. As these facilities attract former drivers, congestion is reduced, and more or new drivers backfill the roadway capacity that was freed up. This project investigates two questions. First, to what extent are VMT reductions from transit and active transportation backfilled by induced traffic? Second, is roadway and parking infrastructure the primary, long-run determinant of VMT in congested urban areas? The second question will explore the extent to which infrastructure needs to be sized proportionately to nearby highway capacity if regional and statewide VMT and greenhouse gas reduction goals are to be realized.
