Spokane Valley uses remote signal data to speed maintenance response

The City of Spokane Valley is using SYO, a remote traffic signal monitoring platform, to give technicians fault data before they go into the field. The move has improved uptime, cut truck rolls and helped the city manage its 56-device signal fleet more efficiently.

Why it matters: - Spokane Valley’s traffic team can identify many signal problems before sending a technician to the cabinet. - Faster diagnosis reduces troubleshooting time, cuts unnecessary truck rolls and lowers operating costs. - The city says the workflow frees staff time for other mobility projects and maintenance priorities.

What happened: - Spokane Valley implemented SYO, a remote traffic signal maintenance and operations platform from Synapse ITS. - The system gives city staff remote access to conflict monitor fault logs, channel voltages and operational records. - Western Systems and Synapse ITS worked with Spokane Valley to fold the platform into daily operations. - City staff review the system at least once a day before heading out. - Spokane Valley uses the platform to monitor a fleet of 56 devices.

The details: - SYO pulls data already available in the conflict monitor and uses the city’s existing field communications network. - The platform aggregates that data into a centralized hosted system accessible remotely by authorized technicians. - Historical logs help staff spot intermittent or recurring issues tied to operational, environmental or seasonal factors. - Spokane Valley staff use the system to review maintenance history and quickly retrieve information when answering questions or troubleshooting field issues. - The city reports higher signal uptime, faster incident resolution, fewer truck rolls and less time spent troubleshooting at the cabinet. - SYO provides the same data through both the SYO Web and SYO App. - Standardized notifications help ensure critical alerts reach the right staff quickly, even when lead personnel are off-site.

Between the lines: - The deployment fits into Spokane Valley’s broader push to expand transportation infrastructure and improve resilience. - The city has been expanding its traffic signal communications network while advancing roadway, intersection, pedestrian and active transportation projects. - Spokane Valley is a participating agency in the Spokane Regional Transportation Council’s Regional Safety Action Plan, developed through the federal Safe Streets and Roads for All program. - In 2026, the city is advancing its first Active Transportation Plan focused on safety, accessibility and connectivity for people walking, biking and rolling. - Remote monitoring helps the traffic operations team improve signal availability and redirect resources toward other transportation programs.

What’s next: - SYO’s ecosystem will expand this fall to support the Polara Accessible Pedestrian Signal. - Spokane Valley plans to use that connected APS capability to support more intelligent operations at intersections. - The city will continue investing in signal modifications, ITS improvements, pedestrian crossings and other infrastructure projects.

The bottom line: - Spokane Valley is using remote signal data to make maintenance faster, keep signals online longer and stretch transportation dollars further.
