Development of New Privacy-preserving Method for Traffic Data Collection and Analysis

Project Summary

Traditional methods for data collection, such as the National Household Travel Survey, focus on trips by a small sample of either travelers, locations, or times. With the prevalence of GPS devices and smartphones, big transportation data from more travelers and locations over longer timespans are more readily available and can substantially help to improve the management, planning, and design of transportation systems. However, travelers, private companies, and public agencies are reluctant to share such data due to privacy concerns. This project will develop a new privacy-preserving method for collecting and analyzing traffic data. This method is based on a new framework for transportation system analysis, in which a network is considered a single entity, and trips are tracked in a relative space with respect to the remaining distance to individual travelers’ destinations. Such data are sufficient for characterizing traffic dynamics but without revealing Personally Identifiable Location Information. This method works for either a city road network or freeway corridors, as well as for multimodal trips. The project will systematically calibrate and validate the new method and will discuss the policy implications for data collection and analysis for California’s traffic systems.

Project Summary

My overall research objective is to produce transportation research on access to opportunity for low-income and communities and people of color, done in partnership with community partners. Through this work, I seek to understand better what transportation access intervention models designed in collaboration with the community can improve people’s life outcomes. Historically, transportation plans and programs have not met the needs of disadvantaged populations.Newer technological advances in transportation — ride-hailing and micro-mobility — have similarly failed to provide increased access to high-need communities partially due to not being scoped and designed in collaboration with the community. For this reason, I seek to advance research towards my research objectives through building relationships with community-based organizations and doing research in partnership to help solve real-world problems.
Many groups of people experience transportation disadvantages and exclusion. People who live in affordable housing are a group of people with lower levels of transportation access with whom transportation researchers are increasingly partnering. People living in affordable housing face
disadvantages because of low household incomes and because affordable housing complexes are located on the “urban fringes” given historical exclusionary zoning practices. Because of this, low-income residents living in affordable housing developments may have higher transportation
costs or have limited access to jobs, healthcare, or educational opportunities (Hickey, et. al, 2012).
I am proposing a community-based research partnership between myself and the UCLA Lewis Center for Regional Policy Studies and the Century Villages at Cabrillo (CVC) development in Long Beach, California. This proposed partnership is inspired by a forthcoming vehicle lending pilot program that the Housing Authority of the City of Los Angeles will soon launch and that myself and Lewis Center Director Evelyn Blumenberg will evaluate. This proposed relationship-building grant with CVC will build on the partnership between UCLA and HACLA and serve as an additional foundation for future collaborations on transportation interventions with housing partners and studying their effects on increasing access to opportunities.

Project Summary

Policy development is driven by information, some of which involves people and organizations. Some of this information includes personally identifiable information (PII) and other sensitive information. Typically, sensitive information cannot be released, so if the data is to be released to justify a policy or the manner in which a policy is to be implemented, the data must be sanitized to remove any sensitive data points. This must be done in a way to preserve the utility of the data, so as to ensure that the policies and practices can be justified. Improving transportation infrastructure requires gathering data to be used in developing, or validating, transportation policies and practices. Sometimes this data must be made available to third parties to carry out analyses or to independently confirm the claims made about policy elements and the way policies are put into practice. Data can be released in two forms: raw data, which is the data as it is gathered, and aggregated data, in which summaries are released. Data is often “sanitized,” or anonymized, to prevent the release of sensitive information. Inferences drawn from the anonymized or aggregated data must be the same as would be drawn from unanonymized data.The goal of this project is to identify and characterize precisely the gaps in the existing research surrounding data sanitization in order to preserve the balance between utility and privacy. In order to identify research gaps that create uncertainty, the researcher will meet with a variety of parties, including policy makers, data analysts, and privacy officers, to answer the following questions: What are the policy requirements for data analysis? How does policy drive the analysis of the data? What parts of the data can safely be released? What parts cannot be released? If the data is aggregated, how does the aggregation work? The researcher will then examine literature on data sanitization, reversing the sanitization, and the theory underlying data sanitization which, when combined with the information gathered previously, will be used to identify specific gaps in the research.
