Tolling system using vehicle identifier correlation

A method performed by a computing system, the method comprising:

• receiving, from at least one detection systems identity tokens of different types for a plurality of moving objects, each of the identity tokens corresponding to a detection event within a detection volume;
• recording a number of occurrences for each of the identity tokens;
• recording a number of co-occurrences for instances in which two different identity tokens pass through a detection volume during a detection time window;
• and
• correlating different types of identity tokens with each other based on a ratio between occurrences and co-occurrences.

A system comprising:

• a plurality of detection systems;
• a computing system in communication with each of the plurality of detection systems, the computing system comprising a processor and a memory with machine-readable instructions that when executed by the processor, cause the system to:
• receive, from the plurality of detection systems, identity tokens of different types for a plurality of moving objects passing through a detection volume;
• record a number of occurrences for each of the identity tokens;
• record a number of co-occurrences for instances in which two different identity tokens pass through the detection volume during a detection time window;
• and
• correlate different types of identity tokens with each other based on a ratio between occurrences and co-occurrences.
