Under Chapter 119 of the Florida Statutes, Miami-Dade County must provide access to any technical documentation requested by the public on time. The Miami-Dade County Department of Transportation and Public Works’(DTPW) Traffic Signals and Signs Division (TSSD) is responsible for more than 4,000 intersection traffic lights. In addition to inspecting and maintaining these critical assets, the TSSD must respond to any public requests for traffic light technical documentation. Most of these requests are related to traffic accidents and judicial inquiries made by lawyers. Other requests originate from consulting firms dedicated to traffic studies, construction contractors, and the public at large. The original, manual process involved TSSD receiving emails and phone calls from requestors and an assigned traffic engineer responding within a few hours. The Information Technology Department (ITD) Geospatial Technologies Division, in conjunction with ITD Transit Services, developed an improved process and solution consisting of two interconnected parts - an Azure Blob Storage to load and access traffic lights technical documentation via URL and a web-based GIS application in ArcGIS Online for the public to self-serve by searching and downloading the technical documentation of interest. Since the solution was deployed in September 2019, the web-based GIS application has received more than 30,000 views, reduced response time from hours to minutes, and has allowed traffic engineers to instead focus on job responsibilities in line with the expertise of the position.
