Portable and permanent traffic analyzers count traffic, and measure vehicle length and speed. The devices then store the data for future analysis, or report conditions in near real time.

Traffic analyzers continue to be the future of ITS as a way to maximize traffic flow with ever growing traffic volumes and limited growth to traffic lanes.

Why are traffic studies needed?

• Mitigation of congestion
• Forecast traffic impact created by new development
• Determine roadway life
• Relate land use decisions with traffic conditions
• Assist with efficiently allocating limited funds
• Used for origin/destination studies
• Provide input for metropolitan planning efforts

There are a multitude of reasons for performing a portable traffic studies. Here are some:

• Short–term traffic studies
• Traffic impact studies
• Stop sign
• Traffic light
• Posted speeds
• Mall development
• Road construction
• Thruways
• Exit and entrance ramps
• Hour – Day – Week studies
• Vehicle volume studies
• Parks or recreational areas
• Construction zones
• Airports
• Casinos
• Military bases

There are countless numbers of ITS companies that provide permanent traffic solutions, but there are a few key things that separate Vaisala from the rest.

Weather and Traffic

Vaisala is one of the few companies in the world that manufactures both weather sensors and traffic sensors. This means that Vaisala is in the best position to offer a solution that combines weather and traffic data into a single, cost effective solution. Vaisala’s Permanent Traffic Analyzer can measure both traffic data and weather conditions for use with RWIS stations or alone.

Points of Interest Monitoring

Vaisala Permanent Traffic Analyzers are also perfect to monitor traffic flow in and out of points of interests, such as shopping centers, casinos, and military instillations. The sensors can detect vehicles moving at slow speeds and in each lane, so they are a perfect fit for this application. In addition, since the sensors are “in” each lane sensors can be placed on curves and around corners where some sensors must remain placed on roads that are straight.

Vaisala’s Permanent Traffic Analyzers will provide quality count, speed, and length data in many applications.
