- A new traffic management system in Espanola, New
Mexico costed $862,279.
- TMC physical components in Lake County, Illinois
costed $1.8 million.
- The cost to retime a traffic signal ranged from
$2,500 to $3,100 per intersection per update from six
separate studies.
- The average cost to retime signals in the MTC
(California) program was $2,400 per intersection.
- The cost of retiming 16 signals at the Mall of
Millenia (Florida) was about $3,100 per intersection.

Notes:
* Overall Cost Range applies to the application of a treatment in roadway segment or corridor. For example, several DMS can be installed along a 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,
Integrated Multimodal Corridors, etc.)
