The Vaisala Permanent Traffic Analyzer TCP500 is a wireless permanent traffic analyzer that collects data without any external sensors, loops, or tubes. It is a self contained, in-pavement sensor that utilizes Vehicle Magnetic Imaging (VMI) technology to detect vehicle count, speed and classification. The Vaisala Analyzer TCP500-B2A also can measure pavement wet/ dry, chemical percent factor, and surface temperature from additional sensors in the lid. The Vaisala Analyzer TCP500-B3A adds even more weather capability by adding an external pavement temperature and subsurface temperature readings. The analyzer reports wirelessly to a site controller alongside the roadway, or it can report to a road weather station (RWIS). The sensor features an easily removable lid, which allows for quick extraction of sensor components during road maintenance or sensor maintenance. The sensor provides accurate and essential data necessary for effective traffic analysis, control and management. When used with Wireless Data Management (WDM) software, historical data can easily be presented in the form of reports, charts, and graphs. The Traffic Analyzer adds a unique, cost effective approach by measuring both weather and traffic through a single sensor. This allows the user to gain either weather or traffic data they might not have previously had access too.
