System and method for visual representation and management of traffic capacity at roadway intersections

A computer system for displaying a supply of traffic capacity at a roadway intersection, comprising:

• one or more processors;
• and
• one or more computer-readable media having stored thereon executable instructions that when executed by the one or more processors configure the computer system to:
• calculate one or more dequeue zone sizes based on phase time duration data for the roadway intersection, wherein the one or more dequeue zone sizes comprise a predicted or estimated length of roadway or a predicted or estimated number of vehicles that can dequeue during a single active signal phase;
• display, at a computer interface, a visual representation of the one or more dequeue zone sizes for one or more approaches of the roadway intersection, wherein the visual representation of the one or more dequeue zone sizes comprises a spatial representation;
• receive an input configured to adjust a particular dequeue zone size;
• calculate, based on the input, an adjusted duration of active time allocated to the adjusted particular dequeue zone size;
• and
• communicate the adjusted duration of active time to a traffic controller that is configured to control the roadway intersection.
