Abstract:The Mid-America Regional Council (MARC) and its program area, Operation Green Light (OGL), manage more than 750 signalized intersections across a nine-county region, as shown in Figure 1. Kansas City Regional Signal System OGL staff members analyze and retime corridors when they notice the need for potential improvements, but this awareness is often delayed because of incomplete or untimely data, lack of skills or resources to analyze available data, or inadequate resources to collect new data. Ideally, each agency and traffic signal would be equipped with advanced equipment and functioning detection to support automated traffic signal performance measures (ATSPMs) however, this infrastructure is too costly for all agencies to install and maintain. Some agencies have installed such infrastructure, but disadvantaged communities face noteworthy challenges in terms of staffing and infrastructure, leading to distinct differences in signal management across the Kansas City metro area. A lack of data and resources in any agency leads to inefficiencies in task prioritization, stretching staff time and negatively affecting roadway operations. The two primary needs for OGL and its partners are to better understand and communicate the status of the Kansas City Regional Transportation System.
The total size of the zip file is 138 MB. The .xlsx files are Microsoft Excel files, which can be opened with Excel, and other free available spreadsheet software, such as OpenRefine. The .txt file type is a common text file, which can be opened with a basic text editor. The most common software used to open .txt files are Microsoft Windows Notepad, Sublime Text, Atom, and TextEdit (for more information on .txt files and software, please visit https://www.file-extensions.org/txt-file-extension). The Portable Document Format (PDF) file format was developed by Adobe Systems and represents two-dimensional documents in a device-independent and resolution-independent format. There are PDF readers available on many platforms, such as Xpdf, Foxit, and Adobe's own Adobe Acrobat Reader. PDF readers/viewers or online services for basic functions are generally free (for more information on .pdf files and software, please visit https://www.file-extensions.org/pdf-file-extension). File extension .json is associated to JavaScript Object Notation file format, a lightweight, text-based, language-independent data interchange format. JSON defines a small set of formatting rules for the portable representation of structured data. It is used by various applications as alternative option to XML file format. The data in a json file are stored in simple text file format and the content is viewable in any simple text editor (for more information on .json files and software, please visit https://www.file-extensions.org/json-file-extension). The .docx file is a Microsoft Word file, which can be opened with Word and other free word processor programs, such as Kingsoft Writer, OpenOffice Writer, Apache OpenOffice, and ONLYOFFICE. The .csv, Comma Separated Value, file is a simple format that is designed for a database table and supported by many applications. The .csv file is often used for moving tabular data between two different computer programs, due to its open format. The most common software used to open .csv files are Microsoft Excel and RecordEditor, (for more information on .csv files and software, please visit https://www.file-extensions.org/csv-file-extension).
