Relay App Screenshots

The goal of this product is to help Traffic Engineers detect, identify, and understand traffic conditions in their network.

These map-based visualizations present various performance metrics as a function of their location, which helps promote the understanding of network-wide patterns which were previously impossible to detect. The use of glyphs to represent quantitative metrics provides a more intuitive understanding of these patterns.

Left: Status
Indicates the working condition of an intersection.

Top: Flow (per intersection)
A heat map indicating the number of cars through an intersection per unit time.

Right: Flow (along roads)
An approximation of the number of cars along major arteries between intersections, based on predictive data from the controller.

Bottom: Queue Length
The average wait time at an intersection.
