GAO’s Cloud-Based Toll Pricing and Access Control Systems

GAO’s cloud-based toll pricing and access control systems deliver real-time automation for toll collection, vehicle identification, lane management, and access authorization across bridges, expressways, tunnels, controlled campuses, and gated infrastructures. These cloud-driven solutions use BLE, RFID, NB-IoT, Cellular IoT, Wi-Fi HaLow, LoRaWAN, GPS-IoT, and UWB to detect vehicles, authenticate users, calculate dynamic toll prices, and validate access privileges. The cloud framework provides high scalability, elastic processing, and simplified integration with existing transportation systems. Operators gain live dashboards, automated billing workflows, accurate traffic analytics, and zero-touch verification. Drawing on our four decades of R&D investment and expert support from our locations in New York City and Toronto, GAO helps agencies, enterprises, and infrastructure operators deliver fast, reliable, and secure tolling experiences across large or distributed environments.

Cloud Architecture of GAO’s Cloud-Based Toll Pricing and Access Control Systems

GAO designs a multi-layered cloud architecture optimized for heavy traffic flow, continuous telemetry, and accurate billing operations. Roadside units, gantries, kiosks, access gates, and enforcement patrols capture data via BLE, RFID, NB-IoT, Cellular IoT, Wi-Fi HaLow, LoRaWAN, GPS-IoT, and UWB. Edge processors filter and encrypt signals before pushing them into cloud ingestion points. A microservices-based processing layer executes toll calculation algorithms, dynamic pricing models, access control policies, payment validation, and compliance check routines. Distributed data lakes store logs, snapshots, vehicle movement histories, and billing evidence. Operators interact through real-time dashboards featuring lane-level analytics, traffic heatmaps, anomaly alerts, audit logs, SLA metrics, and automated violation queues. The architecture supports high availability through load balancers, multi-zone redundancy, event-driven orchestration, and continuous monitoring—standards aligned with reliable transportation technology networks referenced by the U.S. Federal Highway Administration.
