Statewide ITS Maintenance Services
The Statewide ITS Maintenance Services case study shows how Econolite helped support the Iowa Department of Transportation’s intelligent transportation system (ITS) by providing proactive maintenance, repair, and field asset management to ensure reliable operations across the entire state network. A strong maintenance program helps keep systems running, reduces unplanned failures, and keeps traffic information flowing to travelers efficiently.
Program Overview
In early 2022, Econolite Systems, Inc. (ESI) began providing the Iowa DOT with the capabilities, experience, and resources needed to maintain, repair, and grow its statewide ITS infrastructure. The ITS includes devices such as vehicle detection sensors, CCTV cameras, dynamic message signs, weather stations, and safety detectors that are connected via fiber and wireless communications to a central Traffic Management Center (TMC).
Because these systems operate around the clock and support both safety and mobility goals, routine maintenance and rapid field response are essential. Therefore, Econolite developed a comprehensive maintenance strategy that combines proactive inspections with on‑call technicians to keep field assets connected and operating properly.
Maintenance Strategy
The statewide ITS maintenance program includes:
- Routine field inspections and preventative checks
- System diagnostics and on‑call repair services
- Tracking and logging all ITS assets for data‑driven decisions
- Communication upgrades for improved performance visibility
- Rapid response capability to reduce device downtime
Technicians use a centralized maintenance management platform to log condition reports, schedule inspections, and plan repairs. With this structured approach, the team can anticipate issues and make proactive decisions that reduce downtime and improve reliability across the statewide ITS network.
Key Features & Benefits
- Routine maintenance and preventative checks to catch issues early
- 24/7 field response for repairs and diagnostics
- Centralized asset tracking for data‑driven planning
- Improved reliability and uptime across transportation corridors
- Better planning and budgeting for future upgrades
Operational Improvements
As a result of the statewide ITS maintenance program:
- Equipment uptime increased significantly
- Rapid response to maintenance needs reduced disruptions
- Engineers gained better insight into system performance
- Unexpected field failures were reduced
- Confidence in asset condition grew among staff and partners
Overall, this maintenance approach strengthened the reliability of the statewide ITS network, supported data‑driven decisions, and provided a scalable model for future projects and expansions.
