Designing the Archive for SHRP 2 Reliability and Reliability-Related Data (2014)

Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

4C h a p t e r 1 1.1 Objective The second Strategic Highway Research Program (SHRP 2) Reliability focus area has commissioned roughly 30 research projects costing approximately $27 million; together these projects were designed to lay the foundation for understand- ing and improving travel time reliability. In addition to these, seven other projects in the Capacity, Renewal, and Safety focus areas address travel time reliability. The SHRP 2 Reli- ability research and other Reliability-related projects have produced a large collection of raw data sets, analysis results, and documentation (called “artifacts”). Archiving these arti- facts is pivotal to provide a foundation for future travel time reliability research efforts. The objective of the L13A project is to ensure that this rich reliability data and information is available to the transporta- tion research community via an archiving platform (called “the Archive”) that is accessible through the Internet. The Archive will support the continued momentum of travel time reliability research efforts initiated by SHRP 2 for the coming decades. 1.2 target audience The primary audience for the Archive is the following: • University faculty, staff, and students in civil engineering, transportation planning, and logistics/supply chain man- agement who conduct research on travel time reliability and closely related topics; • Researchers from private consulting firms and other pri- vate enterprises involved in analyzing and modeling travel time reliability and closely related topics; and • Analysts, traffic engineers, planners, and managers from road authorities interested in applying the findings to achieve improvements in their road networks. While the primary audience is the transportation research community, the Archive is publicly accessible. Any member of the public or any organization may view and download the artifacts. Further, any member of the public or any organiza- tion may create a user account to participate in discussions about the research. 1.3 Benefits The SHRP 2 Reliability Archive offers the following benefits: • Complete access to all data, analysis results, documenta- tion, and supporting information (nonsensitive informa- tion only) for SHRP 2 Reliability research, enabling users to understand how the original researchers came to their conclusions, replicate or validate their findings, and extend their research; • Features for visualizing data sets in a grid, on a graph, or plotted on a map, enabling users to quickly form a mental model of a data set through visualization; • Simple navigation and quick access to traffic data sets for the user’s research project; • Options for customizing the available traffic data sets to meet the user’s needs and for downloading only the infor- mation that the user desires; and • Quick registration process, enabling a user to create a user account and log in within minutes. 1.4 Summary of archived projects and artifacts The Archive includes a handful of projects from other SHRP 2 focus areas that also address travel time reliability. Non- sensitive data are provided so that they can be accessed and downloaded in an open manner. It should be noted that the Archive excludes data sets that contain personally identifi- able information (PII). Background

5 The Archive includes more than 35 Reliability and Reliability-related projects. At the time of this writing, a total of 526 Reliability-related artifacts have been stored or identi- fied for storage in the Archive. This set of artifacts includes 128 data sets and 398 non–data sets. (For more detailed infor- mation regarding the definition of data sets and non–data sets, see Section 5.1.) Table 1.1 and Table 1.2 provide a sum- mary of archived/to-be-archived projects and artifacts. 1.5 Document Organization Following this background chapter, the remainder of this final report is structured as follows: • Chapter 2, Approach, describes the technical approach to developing the Archive; • Chapter 3, Preparatory Analysis, presents the results of the project team’s literature review and preparatory analysis; Table 1.1.
