Benchmarking “Smart City” Technology Adoption in California: Developing and Piloting a Data Collection Approach

Abstract

In recent years, “smart city” technologies have emerged that allow cities, counties, and other agencies to manage their infrastructure assets more effectively, make their services more accessible to the public, and allow citizens to interface with new web- and mobile-based operators of alternative service providers. This project reviews the academic literature and other sources on potential strengths, weaknesses, and risks associated with smart city technologies. No dataset was found that measures the adoption of such technologies by government agencies. To address this gap, a methodology was developed to guide data collection on the adoption of smart city technologies by urban transportation agencies and other service providers in California. The strategy used involved web scraping; interviews with experts, public agencies, and senior-level staff; and consultations with technology vendors. The approach was tested by assembling data on the adoption of smart city technologies in California by municipalities and other local public agencies.

Double the Trouble: A Playbook for COVID-19 and Evacuations

Abstract

Evacuation and response plans require thoughtful strategies that build mandatory evacuation order compliance, reduce vehicular congestion, and increase social equity for disadvantaged populations. However, the novel coronavirus (COVID-19) pandemic coincided with a series of devastating disasters in 2020 that have required mass evacuations, leading to several new compounding effects (i.e., “double the trouble”). Strategies typically used in evacuations (e.g., high-capacity vehicles and public congregate shelters) and movements of people (e.g., evacuees, first responders, and volunteers) could increase the risk of COVID-19 spread and exposure. Moreover, disadvantaged populations who are already disproportionately impacted by disasters and COVID-19 separately could face new challenges in dual crises. To address these new and growing challenges, this playbook employs insights from case studies (n=12), survey data of individuals impacted by public safety power shutoff (PSPS) events (n=210), and expert interviews (n=17). Using these data, the playbook: (i) shares recent lessons learned from case studies of compounding disasters during the pandemic; (ii) offers a primer for the potential compounding impact of PSPS events and disasters; (iii) highlights current considerations in the emergency management and evacuation fields; and (iv) provides a series of actionable checklists to address COVID-19 and a compounding disaster. Relevant stakeholders in disasters and evacuations that should use this playbook include public agencies, first responders, community-based organizations, non-governmental organizations, private mobility companies, public health facilities, and other evacuation stakeholders. The playbook can be adapted for multiple hazards, different local contexts, various agency types, and future pandemics.

Driving California's Transportation Emissions to Zero

Abstract

The purpose of this report is to provide a research-driven analysis of options that can put California on a pathway to achieve carbon-neutral transportation by 2045. The report comprises thirteen sections. Section 1 provides an overview of the major components of transportation systems and how those components interact. Section 2 discusses the impacts the COVID-19 pandemic has had on transportation. Section 3 discusses California’s current transportation-policy landscape. These three sections were previously published as a synthesis report. Section 4 analyzes the different carbon scenarios, focusing on “business as usual” (BAU) and Low Carbon (LC1). Section 5 provides an overview of key policy mechanisms to utilize in decarbonizing transportation. Section 6 is an analysis of the light-duty vehicle sector, section 7 is the medium- and heavy-duty vehicle sectors, section 8 is reducing and electrifying vehicle miles traveled, and section 9 is an analysis of transportation fuels and their lifecycle. The following sections are an analysis of external costs and benefits: section 10 analyzes the health impacts of decarbonizing transportation, section 11 analyzes equity and environmental justice, and section 12 analyzes workforce and labor impacts. Finally, future research needs are provided in section 13. The study overall finds that cost-effective pathways to carbon-neutral transportation in California exist, but that they will require significant acceleration in a wide variety of policies.

Hydrogen Infrastructure Requirements for Zero-Emission Freight Applications in California

Abstract

Zero-emission vehicles are seen as key technologies for reducing freight-related air pollution and greenhouse gas emissions. California’s 2016 Sustainable Freight Action Plan established a target of 100,000 zero-emission freight vehicles utilizing renewable fuels by 2030. Hydrogen fuel cell vehicles are a promising zero-emission technology, especially for applications where batteries might be difficult to implement, such as heavy-duty trucks, rail, shipping, and aviation. However, California’s current hydrogen infrastructure is sparse, with about 25 stations, primarily sited to serve fuel cell passenger vehicles and buses. New infrastructure strategies will be critical for implementing hydrogen freight applications. The researchers analyzed hydrogen infrastructure requirements, focusing on hydrogen fuel cells in freight applications, using a California-specific EXCEL-based scenario model developed under the Sustainable Transportation Energy Pathways program (STEPS) at the Institute of Transportation Studies at UC Davis (Miller et al, 2017). Hydrogen vehicle adoption and demand was estimated for trucks, rail, shipping, and aviation, for a range of scenarios out to 2050.

Answers from the Margins: Participatory Planning with Disadvantaged Communities

Abstract

The public mandate to engage the public in transportation planning processes is in the process of becoming more rigorous and democratic. Transportation agencies are recognizing the limitations of past modes of engagement and seek to connect more dynamically with the public, particularly with historically marginalized communities. Doing this work well is a topic of interest to a growing number of transportation professionals. This study identified four successful engagement processes with historically marginalized communities in California by surveying transportation professionals. Stakeholders at each site were interviewed and public documents from the processes were reviewed to identify common themes for positive public inclusion. Interviewees included community leaders, transportation staff, and consultants. Interviews were coded and analysis was conducted using a mobility justice and critical race studies framework. Ten key themes of successful community engagement with historically marginalized communities were identified. These themes are: (1) trust is crucial; (2) treat community-based organizations as equal partners; (3) pay community partners fairly; (3) let community-based organizations decide what good community engagement is; (5) translate technical jargon; (6) engage in community concerns beyond the scope of the project; (7) address major community concerns such as displacement, policing, and youth development; (8) know local histories of transportation injustice; (9) include the community in the final reporting process; and (10) follow-up on planning with implementation in a timely manner.
