Abstract: A platform for visualization of traffic information at an observed roadway or traffic intersection converts data collected from sensors for rendering as dynamic animations on a virtual map of the observed roadway or traffic intersection. The platform parses and curates incoming sensor data from either a single or multiple sensors representing one or more objects at the observed roadway or traffic intersection, and translates at least location data of each object for correlation of the object's movement relative to the observed roadway or traffic intersection. The platform then generates dynamic animations of the movement of each object and displays the animations as an overlay on the virtual map.

Abstract: Techniques and mechanisms are disclosed that enable a data intake and query system to generate and cause display of circular timelines of timestamped event data. As used herein, a circular timeline generally refers to a graphical display of timestamped events stored by a data intake and query system, wherein the timestamped events may be displayed as arcs of one or more concentric circles and located in a circular timeline area according to a chronological ordering associated with the events. One or more display attributes of each arc may further depend on other data associated with the corresponding events. For example, each arc of a circular time may be displayed at a particular radial distance, with a particular thickness, using a particular shading and/or color, etc., depending on various data values associated with the one or more events represented by the arc.
