Honolulu HI Traffic Communications Network Integration
Econolite was selected as the prime contractor by the Hawai‘i Department of Transportation (HDOT) to upgrade and modernize the Honolulu, HI traffic communications network. HDOT needed a more robust system for critical devices such as changeable message signs (CMS), CCTV cameras, traffic detection systems, and barrier gate monitoring, transmitting data reliably to the operations center.
Project Overview — Hawaii DOT Communications Modernization
The project focused on replacing outdated serial communication devices with modern Ethernet-based solutions. Econolite conducted fiber strand testing and repairs, executed a detailed migration plan, and integrated Ethernet devices into the field network to ensure traffic control systems remained operational throughout the process.
Key work included:
- Fiber strand testing and multimode/single-mode fiber repairs
- Planning and executing a communications network migration
- Removal of outdated serial devices and installation of Ethernet equipment
- Integration of switches, terminal servers, and voice gateways
- Installation of network monitoring software to support long-term maintenance
- Collaboration with HDOT to transition field devices without service interruptions
Benefits of Honolulu Communications Network Upgrade
This communications infrastructure upgrade provided:
- Reliable, high-speed Ethernet connectivity for traffic devices
- Network redundancy using a hybrid of gigabit and 100 Mbps links
- Improved data transmission for CCTV, CMS, and detection systems
- Enhanced operational efficiency for HDOT staff
- Better support for future ITS deployments throughout Honolulu
Related ITS and Traffic Technology Initiatives in Honolulu
Alongside the communications network project, Honolulu engaged in ITS advancements, including connected vehicle and signal optimization pilots in collaboration with the University of Hawai‘i and HDOT. These initiatives improve traffic safety and mobility on corridors like Ala Moana Boulevard and Nimitz Highway.
About Econolite’s Traffic Management Solutions
Econolite provides advanced Intelligent Transportation System (ITS) solutions to modernize traffic communications, improve safety, and manage mobility effectively. With extensive experience in fiber optic communications, Ethernet integration, and network monitoring systems, Econolite supports agencies like HDOT in deploying scalable, future-ready infrastructure.
Econolite Systems was selected as the prime contractor based on the submitted proposal and staff experience. Hawaii DOT maintains hundreds of ITS devices across the islands. Due to obsolete communication devices, Hawaii DOT needed to upgrade the H-3 ITS communication system, which transmits CMS, CCTV, traffic detection, and barrier gate data to the traffic operations center through serial communication. The project included fiber testing, repairs, migration planning, serial device removal, Ethernet device installation, field device transition, and training.
Econolite submitted fiber testing results on 5 miles of multimode and single-mode fiber, documented the new system architecture, and proposed a new plan for redundancy using a hybrid of gigabit and 100 Mbps links. Econolite developed a step-by-step migration methodology to minimize disruptions, installed and integrated hardware and software including switches, terminal servers, and voice gateways, and worked alongside Hawaii DOT staff to ensure end devices were unaffected. Network monitoring software was installed to support ongoing maintenance, and over 100 traffic devices were successfully transitioned to Ethernet communication.
