MIRS (Manual Image Review System)

Manual image reviews in an otherwise automated electronic toll collection (ETC) system may seem to represent an irreducible drain on profitability—an inevitable part of using any ETC solution that incorporates automatic license plate recognition (ALPR) technology.

Despite the improvements in automation for toll transaction image capture and review, manual image review remains an important part of the revenue assurance program for every tolling agency. Each agency has its own unique mix of in-state and out-of-state traffic along with an ever-growing list of specialty license plates. Add to this the increase of All-Electronic-Tolling (AET) along with new bill-by-plate features and the manual image review process continues to grow in importance for all toll operators.

MIRS combines new technology with a highly flexible design to optimize work flow for the many uncertainties that surround the manual image review process.

Unexpected fluctuations in volume, personnel turnover, training requirements, processing accuracy, consistent performance monitoring, and end to end auditability are just some of the major factors that were part of the design for MIRS.

An investment in MIRS provides toll operators with a technology platform designed for “continuous improvement.” With MIRS, tolling agencies can fine-tune their processes to ensure the highest quality and consistency from their manual image review program. An investment in MIRS is an investment in the ongoing improvement of your business.
