The TrailerCam Advanced traffic management system includes a new heavy-duty TrailerCam with mounted webcams and multi-lane detection sensors coupled with EarthCam’s Traffic Management software. The software displays a unified interface with complete live and archived multi-lane information. The system includes EarthCam’s dynamic visualization and flow graphs of density, volume, speed and vehicle class by lane for up to 10 lanes. Selectable triggers activate VMS sign information, as well as email and online alerts. Each lane flow is calculated automatically in five minute increments and archived for reference and tracking studies.
