Abstract
Managing traffic signal preemption data accumulated at a plurality of intersections. In one approach a method includes reading the preemption data stored at each of the intersections. The preemption data includes for each preemption request an emitter code, and a date and a time the preemption request was submitted. The preemption data read from the intersections are stored in a database, and each emitter code is associated with a vehicle name in the database. Selected preemption data and associated vehicle names are read from the database in response to user input, and the selected preemption data and associated vehicle names are displayed. The database further stores data identifying the intersection from which the preemption data was read.
