VTA Vehicle Realtime Information Proxy

VTA collects real time GPS information from cellular WiFi network devices on-board the transit vehicles.  Data is sent via XML HTTP request to this application's RESTful API endpoints.  Service workers relay GPS data to public transit information providers and the SCADA system.

VTA implemented the Symfony 4 micro-kernel framework using only the essential dependencies, assets, scripts, plus business logic models required for high performance reliability, stability and accountability with logging of message delivery receipt confirmation.
