This project developed guidance for local agencies, MPOs, and state DOTs to utilize the rapidly emerging data being collected and processed by the private sector in urban and metropolitan areas. The study defined and described new data sources; examined approaches, methods, and analytical techniques that enable agencies to better carry out their planning, programming, and operations responsibilities.
Published in 2010, this report presents requirements and specifications for a scalable national freight data architecture to link myriad existing datasets.
The objective of this ongoing TRB project is to demonstrate the feasibility and practical value of big data approaches. The goal is to improve TIM via real-world application of the Research Report 904 guidelines with selected states and TIM use cases.
NCHRP 07-20 Guidance for Implementation of TIM Performance Measurement provides guidance on the consistent use and application of TIM performance measures in support of the overall efforts of TIM program assessment.
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.
Examines a proposed common framework for exchange of transportation data in eXtensible Markup Language, known as TransXML. The framework is designed to be used for developing, validating, disseminating, and extending current and future schemas.
Provides guidance for the development and management of effective Enterprise Information Portals (EIPs) at state departments of transportation. EIPs have become key tools for transportation agencies as they make available information about the transportation system and the agency’s activities. Such EIPs must be curated; that is, there are people responsible for establishing the portal architecture, ensuring the quality of information and data, and maintaining the reliability of access.
This paper presents guidelines for transportation planners and travel modelers on how to (1) evaluate the extent to which cell phone location data and associated products accurately depict travel, (2) identify whether and how these extensive data resources can be used to improve understanding of travel characteristics and the ability to model travel patterns and behavior more effectively, and (3) support practitioners’ evaluation of the strengths and weak
NCHRP Research Report 904 provides guidelines for states on leveraging a big data approach, including collecting and storing more (and raw) data, opening and sharing data, breaking down data silos via a common data storage environment, and maintaining data accessibility, amongst others.
Provides practical guidance to transportation agencies to help improve their use of data for performance management.
