The purpose of this evaluation is to assess the feasibility and acceptability of using the Autoscope Machine Vision Vehicle Detection System (Autoscope) on the Indiana Department of Transportation highway system. The Autoscope is a system that monitors vehicles on a roadway via processing of video images and provides detector outputs to a traffic signal controller. The system consists of image sensors (cameras), an automatic control unit (ACU), a supervisor computer, and software.
To evaluate
the Autoscope, three units were installed at three different locations
(intersections). The evaluation of this device consisted of: 1) requiring
NEMA environmental tests for the Autoscope; 2) obtaining the environmental
test data from the camera manufacturer; 3) observing the ease of installation;
4) observing the performance of the Autoscope during different weather
conditions; 5) assessing the cost-effectiveness of using the Autoscope;
and 6) obtaining comments from INDOT's Fort Wayne and LaPorte districts'
personnel via a questionnaire about the Autoscope's performance.
On January
25, 1996, the Econolite Control Products, Inc. submitted the Autoscope's
specification. After the specification was reviewed, it was found that
the Autoscope model 2004 is in compliance with the requirements described
in the report. It was recommended that this product be approved for use
on the Indiana Department of Transportation highway system and be included
in the next "LIST OF APPROVED AND/OR PREQUALIFIED MATERIALS"
effective date May 1, 1996.
