Real-Time Traveler Information System in a Work Zone Cost $79,545.

In 2014, the Federal Highway Administration published the Work Zone Intelligent Transportation System (WZITS) Implementation Guide to provide information on implementing ITS in work zones. This 2021 Technology Supplement was intended to be used in conjunction, providing a detailed factsheet and sample specifications for nine primary WZITS technologies: 1) Dynamic Lane Merge, 2) Queue Warning, 3) Variable Speed Limit, 4) Automated Enforcement, 5) Entering/Exiting Construction Vehicle Notification, 6) Temporary Ramp Metering, 7) Real-Time Traveler Information, 8) Incident Management System, and 9) Performance Measurement. This summary provides an overview of the costs related to implementing Real-Time Traveler Information Systems (RTIS). RTIS provides roadway information, such as weather, traffic, and work zone conditions, that empowers drivers to make better decisions. Travel time information for RTIS deployments can be calculated using probe data, projections from past traffic data, or real-time crowd-sourced, app-enabled data.

The cost of RTIS varies based on the use of existing equipment, the area of deployment, and if an agency buys or leases the equipment. Table 1 below lists example unit and total system costs.
