With increased connectivity between vehicles, sensors, systems, and mobile devices, unexpected and unparalleled amounts of data are being added to the transportation domain at a rapid rate. Within these pages, readers will find information related to the integration and management of data from connected vehicles and devices.
Connected vehicle technologies aim to tackle some of the biggest challenges facing the surface transportation industry in the areas of safety, mobility, and environment. Connected vehicles could dramatically reduce the number of fatalities and serious injuries caused by crashes on roads and highways. Anonymous signals in connected vehicles will help generate new data about how, when, and where vehicles travel. Connected vehicle technologies will generate real-time data that drivers and transportation managers can use to make green transportation choices.
Data from connected vehicles have tremendous potential to offer new insights. This has the ability to identify unique solutions for delivering services and will fundamentally alter the transportation sector. However, the volume and speed at which these data are generated, processed, stored, and sought for analysis are unprecedented. They are too large, too varied in nature, and will change too quickly to be handled by the traditional database management systems of most transportation agencies. Instead, modern, flexible, and scalable “big data” methods to manage these data need to be adopted by transportation agencies if the data are to be used to facilitate better decision-making.
Following are needs of transportation agencies with respect to managing data from emerging technologies, such as connected vehicles, as identified in NCHRP 08-116
08-119 Research Products:
For this product, the research team will ascertain the potential value of CV data to transportation agencies via a detailed assessment of various CV datasets obtained from both public and private sources. Many resources are already available that describe the immediate, individual vehicle safety applications, such as emergency brake light warning and red-light violation warning. This product will not revisit these materials; rather, it will focus on using the CV data for managing roadways and planning future operations.
This white paper describes smart/connected cities and outlines their potential for interfacing with the emerging connected transportation environment.
This report represents the Data Management Plan for Phase 3 of THEA’s CV pilot deployment project.
This resource presents the Data Management Plan (DMP), which describes the data that will be collected and how the data will be managed throughout the Wyoming CV Pilot. The DMP will also define a framework for sharing the data with USDOT, the Research Data Exchange and the Independent Evaluator.
This resource represents a data management plan that delineates all of the data types and data treatment throughout the New York City Connected Vehicle Pilot Deployment (NYC CVPD). This plan includes an identification of the New York City connected vehicle pilot privacy-related data, its security treatment and the necessary filtering, anonymization and obfuscation requirements needed for distributing the data for Independent Evaluator (IE), USDOT and researcher use.
This report provides agencies responsible for Transportation Systems Management and Operations (TSM&O) with an introduction to successful Big Data tools and technologies that can be used to aggregate, store, and analyze new forms of traveler-related data that may be useful for operations.
This NCHRP report identified over 70 CAV projects across the Untied States. In a survey of a subset of these projects, responses were rather incomplete on topics including data management, data openness, data sensitivity, and data retention. Interviews were conducted with 11 state and local transportation agencies and a stakeholder workshop was conducted with 15 state and local agencies.
The purpose of this report is to 1) Identify how big data tools and technologies can be used in traffic management systems or TMCs; 2) Develop potential use cases for integrating big data technology and tools into traffic management systems or TMCs; 3) Assess how connected vehicle and traveler related data could be used to enhance the operation of traffic management systems or TMCs; 4) Analyze how the sharing of data with other TMCs, systems, connected vehicles and travelers; and agency business proce
This report describes requirements, technical issues, technologies, and practices that will be necessary to collect, process, store, use and share large volumes of messages from road side equipment (RSE) to the traffic management centers (TMCs). These recommendations could find their way into data sharing standards for connected and automated vehicles (CAV) that could better define practices.
In 2015, the USDOT awarded cooperative agreements to three pilot sites to implement a suite of connected vehicle applications and technologies. One of the key goals of the CV Pilot program is to produce and provide Open Data from the pilots to the public in a quick and useful manner. This will enable research into the effectiveness of emerging ITS technologies, preliminary development of third-party applications, and harmonization of data across similar collections.
This program describes the sensitivities with the types and amount of data that need to be collected. Additionally discusses the need for a data governance framework that provides a metadata standard and outlines how data will be collected, managed, and archived.
On May 14, 2020, the Utah DOT hosted a webinar on the new V2X project with Panasonic to bring awareness to UDOT’s efforts to further expand V2X technology, create a scalable solution to capture and analyze V2X data, and launch a cloud-based V2X Data Ecosystem (VDE) to enable data sharing, analytics, and innovation.
The ODE is a real-time virtual data router that ingests and processes operational data from various connected devices—including vehicles, infrastructure, and traffic management centers—and distributes it to other devices and subscribing transportation management applications.
