Introduction to speed displays introduces their role in planning and monitoring speeds in urban areas. Introduction is followed by a presentation of task methodology with basic terms, a brief description of radar equipment operation and data collection and processing. Selected statistical tools used to analyze speed measurement data are added. Data sources, data collected, assumptions and limitations encountered in the study are presented. Second chapter concludes with descriptions of where samples were taken and where speed measurement devices were placed. Third chapter presents simple analyses of relationship between speed measurement data and estimated number of newly infected individuals, from which estimated active cases number using the agreed method was derived. The analyses are presented by places. Speed classes, correlation coefficients obtained from comparison of daily indicators of speed display data and active cases, clustering observed in plots of maximum daily speeds and estimated number of active cases are presented in tables and graphs. Third chapter concludes with descriptions of results and locations of individual speed displays in urban areas. Fourth chapter comments on third chapter analyses. Final chapter draws conclusions organized by aspects.
