SERVICES

In order to create an environment where residents have a more livable community we conduct traffic studies from which we create data files used in the community planning process.

Roundabout

Studies include:

Automated:

  • Volume
  • Speed
  • Classification

Manual:

  • TMC
  • Other

For automated studies we specialize in the use of Radar technology, as we believe it to be the most accurate and reliable equipment available. For evaluations of non-intrusive traffic detection systems, please see:

Our extensive research indicates that the accuracy of our Generation 1 Jamar Radar Recorder is superior to that of pneumatic road tubes:

This saves our customers time and money.

Our Generation 2 Black Cat sensor is similar to our Jamar Radar Recorder: Doppler Radar accurately records Volume and Speed. Also, this revolutionary device is a powerful classifier, able to accurately measure vehicle length, on roadways of up to four lanes.

With our Houston Radar Crossfire we now have the ability to accurately survey up to six lanes of traffic, further reducing the need for the use of tubes or loops. As this is a true side-fire device the concern for occlusion is eliminated.:

Such accuracy for temporary surveys of high volume roadways has simply not been available, until now.

Our considerable array of equipment includes both Doppler and FMCW technologies, enabling us to apply the most effective equipment to most any location.

For those customers who prefer the use of pneumatic tubes, we also use Jamar Apollyon Classifiers.

Thus, classifications can be recorded according to either vehicle length, or axle length.

 

For manual surveys we use video.
