TSI has implemented a variety of transportation related projects, from PLC based bridge controls for boat passage to vehicular tunnel security. In addition TSI has integrated DC power system monitoring for the bus transportation system. Many rivers and waterways throughout the Pacific Northwest have bridges utilizing TSI control systems.

Using PLC’s and operator interfaces, these bridges allow boat traffic past low level bridges. Bus tunnels in Seattle have automated security systems with CCTV to automatically shut off the tunnel to traffic in case of a security situation. To monitor the electric bus power grid, TSI engineers installed and commissioned a telemetry and monitoring system at many DC substations. TSI is ready and prepared to facilitate any custom transportation project.
