What is ITS
The integrated application of advanced computer, electronics, and communications technologies to increase the safety and efficiency of transportation is known as Intelligent Transportation Systems (ITS)
- ITS Includes communications, sensors, information processing, controls, and other technology-based strategies to facilitate the movement of people, goods, and information to save time, lives and money.
- ITS strategies are used for toll roads, the movement of freight (trucking, railroads, marine, and air), public transportation, intermodal, 'smarter’ CV/AV vehicles on the roadway, weather and traffic information, emergency medical services, electronic payment systems, internet applications, cellular phone systems, and just about anything else you can imagine that can involve transportation.

Active Traffic ManagementFHWA definition: "The ability to dynamically manage recurrent and non-recurrent congestion based on prevailing and predicted traffic conditions. Focusing on trip reliability, it maximizes the effectiveness and efficiency of the facility. It increases throughput and safety through the use of integrated systems with new technology.

Definitions - CAV, V2V, V2I, V2X- Connected Automated Vehicles – Using connectivity
among systems to enhance autonomous technology.- Connected Vehicles – Using communication technology
vehicle-to-vehicle (V2V), vehicle to infrastructure (V2I), vehicle to anything (V2X) to enhance safety and mobility.
- Autonomous Vehicles – Using sensors, cameras, LIDAR, GPS, and other on-board technology to operate with reduced, limited, or no human interaction.
- Dedicated Short Range Communications (DSRC) – A radio band allocated by the FCC for ITS and public safety (5.9GHz). The protocol is similar to in-home WiFi, but was designed to facilitate large amounts of data transfer at very high speeds and under varying conditions.

Adaptive Lighting - Policy
Nimmo Parkway Corridor
Lights are always on, but dim as the night goes onbased on schedule times
Schedule on/dim/off times to light the area in hours of heavy use but dim and/or turn off during the dead of night for wildlife
Lights are always on
