This paper introduces big datasets, concepts, knowledge, and methods used in traditional transportation planning as well as modern data science.
This white paper describes smart/connected cities and outlines their potential for interfacing with the emerging connected transportation environment.
This presentation recommends the development of a regional transportation big data strategy: creating a regional transportation big data portal, providing consistent and transparent data collection, management, and reporting. Additionally discusses establishing regional standards for transportation data sourcing, formatting, privacy, security, ownership and reporting.
In 2019, the California Department of Transportation (Caltrans) conducted a study to investigate the tools and data needed to support the development of a standardized system to gather all TIM data and report on the three national TIM performance measures statewide.
TCIP is an extensible and modular standard allowing for data exchange between transit business systems, subsystems, components, and devices. It covers C2C, agency-to-public, agency-to-infrastructure, and system-to-system communications. The benefits extend beyond vehicles, operations, and passenger information to business systems and subsystems noted above.
Three prominent data standards have been developed in the transit industry:
The Transit ITS Data Exchange Specification (TIDES) is a conceptual framework for accessing and managing transit agency ITS data. TIDES includes a set of common data APIs that provide access to the different aspects of ITS data (e.g., raw data from vendor systems, secondary data sources that integrate and aggregate the ITS data).
This report reviews recent advances in harnessing big data to understand travel behavior and inform travel demand models. Analyzes the existing data-mining methods that enable these collected mobility traces to inform transport demand models.
TDC is an initiative at the University of Washington (UW) to create a protected and linked data repository of sensitive information from public and private transportation providers. https://www.uwtdc.org/
The purpose of this committee is to provide a focal point for expert system research activities across the various transportation-related disciplines, and to act as a forum for the evaluation and dissemination of information relative to the benefits of the technology to the transportation profession. It is understood that other TRB committees, where appropriate, will have subcommittees on expert systems for their specific domain.
