37.563 Application Field and Working Principle

Developed by the National Institute of Standards and Technology (NIST), 37.563 is a standard that provides specifications for the meaningful use of travel duration and weather related data within vehicular traffic applications. This paper will provide an overview of the application field and the working principle of the standardized specification.

Application Field

The goal of the 37.563 specification is to enable the effective utilization of data collected by intelligent transportation systems (ITS) to allow for better traffic flow management. This includes collecting travel duration and weather related data from selected regional areas and analyzing it for an array of purposes. The data can be used for traffic monitoring, travel time estimation, incident monitoring and response, simulation of traffic conditions, prediction of highway use and changing traffic management practices based on historical data. In addition, agencies responsible for planning and managing roads and highways can utilize the data collected from different sources for better decision-making.

The standard defines various types of data that can be collected, including roadway traffic flow, travel time, weather, incident detection, and other related parameters. This provides greater flexibility for ITS applications, enabling them to access a wide variety of useful information and apply it to various projects.

Working Principle

The 37.563 specification defines a series of standards and protocols for the meaningful use of travel duration and weather related data within ITS applications. The standard provides guidance on how to collect, interpret, store, analyze, and present data collected from various ITS sources. In addition, the standard describes a process for specifying the specifications, as well as a framework for data exchange.

The standard specifies a uniform set of data parameters and structures that are to be followed by the devices or systems that collect and process the data. This ensures consistency across data collected from different sources, allowing for accurate analysis of data. It also ensures that collected data can be readily shared and used by other systems or applications.

In order to make data collected by ITS applications useful, the standard defines a process for processing and interpreting the data. This includes data cleansing, feature extraction, analysis, and communication. The resulting data is then utilized by other applications or systems to generate meaningful results, such as traffic flow diagrams, real-time recommendations, or forecasts.

37.563 is a widely accepted standard that is used by many ITS providers and agencies. The standard is designed to provide a consistent approach to the collection, interpretation, storage, analysis, and communication of ITS data. This helps to ensure that the data collected from different sources is reliable and can be used effectively for decision-making purposes and to improve traffic conditions.
