Authorized Taxicab Supervision, supporting ground transportation operations at Los Angeles World Airports

MJM Innovations’ Department of Transportation (DoT) platform and support services

When a major relocation connected to the Los Angeles World Airports New People Mover and Modernization Project was delayed unexpectedly, Authorized Taxicab Supervision faced the prospect of manually reconciling 1,000–2,000 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 authorized 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. 

Maintaining continuity when a relocation timeline changed

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 1,000 to 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 transaction threshold. The control was designed to prevent misuse; in this situation, it 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 need. 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. Two of four digital signs had been mounted in the wrong sequence on the entry gantry, which would have displayed messages in the wrong order. The contractor had already left, and the signs were approximately 12 feet above ground. 

MJM identified a remote solution: a virtual swap of the static IP assignments in the system configuration. The display sequence was corrected without requiring lift equipment or a physical remount. 

• Preserved complete revenue tracking during a multi-day disruption to automated transaction processing 

• Enabled manual entry for an estimated 1,000–2,000 daily transactions while the operation relied on paper dispatch logs 

• Delivered an operational workaround within 24 hours of the request 

• Corrected a physical signage sequencing issue remotely, avoiding equipment rental and additional contractor coordination 

• Supported a West Coast operation across a three-hour time difference during a time-sensitive transition 

“Within 24 hours, Paul and his 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.” 

“This is not a one-time story. This is just what MJM does… ‘just in time’ support, any hour of the day.”

Airport and ground-transportation environments cannot pause when a construction schedule changes, a system is 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 help teams keep service moving when the plan changes.
