The pilot project includes seven speed radar detectors to register traffic counts and track drivers' speed outside and inside the test zone.

‘The variable we're looking for is motorist behavior,' CDOT environmental specialist Tony Cady said. ‘To test the validity of this system, we need to determine if there's a drop in speed and also whether this is a long-term behavior change, or just something motorists stop reacting to after a period of months.'"
