Small, lightweight, and ultra-portable, the TDC 2 allows you to collect traffic data accurately and discretely.

TDC 2 Traffic Data Collector from Stalker Street Dynamics

Small Size. Huge Features.


Messaging signs and radar 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 Street Dynamics Traffic Data Collector 2 (TDC 2).

Encased in a weatherproof housing that is approximately the size of a paperback novel, the TDC 2 utilizes our legendary radar technology to collect data on both approaching traffic (i.e.- vehicles moving towards your sign) and receding traffic (i.e.- vehicles moving away from your sign) so you can measure traffic data on both sides of your street with one convenient traffic system.

Pair your TDC 2 with optional 4G to the Street Dynamics Web Portal to access your live data from anywhere, or download stored data from your TDC 2 via USB and view it in the included Easy Analyst software. Either option allows you to create beautiful, NHTSA-compliant free-flow traffic counts, speed analysis charts, traffic flow graphics, and more.

Check on the overall status of your TDC 2 from the safety of your vehicle via your phone with the TDC 2’s included short range wireless capabilities, or from your desk if your TDC 2 is equipped with optional 4G. 

Use your traffic data to support grant applications, community policing efforts, and infrastructure planning.
