Notes:
* Overall Cost Range applies to the application of a treatment in roadway segment or corridor. For example, several DMS can be installed along an important
route.
**Unit costs were found by adding the unit cost of different equipment for each treatment. This methodology does not apply to all treatments (e.g., TMC,
Intergrated Multimodal Corridors, etc)
