Authorized Taxicab Supervision — ground transportation at Los Angeles World Airports
When a major relocation connected to the Los Angeles World Airports New People Mover and Modernization Project was delayed unexpectedly, Authorized Taxicab Supervision (ATS) faced the prospect of manually reconciling 2,000+ daily transactions for several days. A safeguard in the existing system prevented staff from posting charges to accounts that had reached a zero or below-threshold balance, an appropriate control under normal conditions, but a barrier during this exceptional disruption.
MJM Innovations engineered a workaround within 24 hours, allowing ATS staff to record transactions against accounts carrying a negative balance. The change preserved complete revenue tracking while the team operated from paper dispatch logs. After the move, MJM resolved a separate digital-sign sequencing problem remotely, avoiding the need for lift equipment or a return visit from the installation contractor.
Authorized Taxicab Supervision was preparing to move a large transit operation to a new site. The plan was ambitious but clear: bring all technology online at the new location, including a fully automated vehicle transaction-processing system, within 24 hours. On the scheduled moving day, the team decommissioned its live AVI readers, transponders, digital signage, and related equipment. Then an unexpected construction issue delayed the project by several days.
Collecting cash for the extended period was not considered a safe option. The alternative was to back-charge every trip manually from paper dispatch logs: roughly 2,000+ transactions per day. But the system’s original safeguards prevented staff from entering a manual charge when a member’s prepaid balance had reached zero or fallen below the minimum threshold. The control, designed to prevent misuse, now threatened to halt data entry and make it difficult to track the growing deficit across affected accounts.
Authorized Taxicab Supervision contacted MJM Innovations’ DoT team with an urgent request: enable authorized staff to enter manual transactions and allow accounts to carry a negative balance while the automated system was unavailable.
Within 24 hours, MJM engineered a workaround that met the operational needs. The team could continue logging transactions during the delay, maintain a complete record of revenue activity, and reconcile account balances once the relocation was complete.
When equipment was reinstalled, a second issue emerged. Four digital signs had been mounted on the entry gantry in the incorrect sequence, which would have resulted in vehicle traffic direction instructions being displayed out of order. The contractor had already left, and the signs were roughly 12 feet above ground. MJM identified a remote fix, a virtual swap of the static IP assignments in the system configuration, correcting the display sequence without lift equipment or a physical remount.
Revenue tracking preserved
Complete revenue tracking was maintained during a multi-day disruption to automated transaction processing.
Continuity at volume
Manual entry was enabled for an estimated 2,000+ daily transactions while the operation relied on paper dispatch logs.
Fast turnaround
An operational workaround was delivered within 24 hours of the request.
Remote signage fix
A physical signage sequencing issue was corrected remotely, avoiding equipment rental and additional contractor coordination.
Cross-country support
A West Coast operation was supported across a three-hour time difference during a time-sensitive transition.
Why It Matters for Airport & Ground-Transportation Operators
Airport and ground-transportation environments cannot pause when a construction schedule changes, a system goes temporarily offline, or installation work introduces an unexpected error. This experience illustrates the value of a technology partner that understands both the operating controls needed in normal conditions and the practical adjustments required to maintain continuity during an exception. For operators managing relocations, modernization projects, or high-volume transaction environments, responsive support can protect revenue visibility, reduce manual-work burden, and keep service moving when the plan changes.
“Within 24 hours, the MJM team had engineered a workaround that did exactly what I asked for, allowing accounts to carry a negative balance, keeping our revenue tracking intact without missing a single transaction.”
