- Research and implement a statewide ITS maintenance management system (MMS). An MMS logs and tracks ITS maintenance activities, resulting in more efficient TOC operations for both in-house and contract maintenance.
- Develop in-house fiber optic cable maintenance and consider adding network systems technician positions. An in-house maintenance capability will ensure that resources are available to fix ITS systems, thus keeping downtime to a minimum. Major problems associated with fiber optic cable maintenance include the slower response time of outside contractors and their lack of expertise. Their performance also requires close monitoring for quality control. Two TOCs in New Jersey have expressed a preference for maintaining fiber optic cable links internally if proper resources are made available. Such resources include trained crew, spare cables, splicing equipment and diagnostics scopes, fusion process materials and equipment, and continuous training.
- Strengthen statewide ITS support contracts. Statewide ITS maintenance contracts should include preventive maintenance of ITS devices such as closed circuit television (CCTV), variable message sign (VMS), highway advisory radio (HAR), and detector stations, along with a preventive maintenance checklist and performance measures. With a preventive maintenance program in place, ITS devices will be checked more frequently, which will in turn result in improved system operations.
- Purchase vehicles dedicated to performing in-house maintenance. The availability of on-site vehicles to perform repairs and routine maintenance will significantly reduce costs and system downtime. It will also add capabilities to meet statewide emergency needs; for example, a dedicated vehicle can be quickly deployed to facilitate installation of temporary devices during an evacuation.
- TOCs, including the New York City Department of Transportation, Colorado Transportation Management Center, and Los Angeles Department of Transportation, all report highly productive use of bucket trucks and network vans to repair CCTV, VMS, cable plants, and overhead microwave detectors.
