Collect The Traffic Data You Need

Messaging signs and speed trailers work to slow down traffic and modify driver behavior in the vicinity of the sign. But if you want to study how people are driving when they feel like no one is watching, then you need a solution like the Stalker Traffic Data Collector (TDC). 

Housed in a weatherproof, lockable housing, the Traffic Data Collector utilizes Stalker’s legendary radar technology to collect data on both closing traffic (i.e.- vehicles moving towards your sign) and away traffic (i.e.- vehicles moving away from your sign) so you can measure traffic data on both sides of your road with one convenient traffic system. 

Once you have collected your data, you can download it into the included Stalker Easy Analyst software to create beautiful, NHTSA-compliant free-flow traffic counts, speed analysis charts, traffic flow graphics, and more.

The software is intuitive and easy to use, and the reports can be used to support grant applications, community policing efforts, and infrastructure planning.
