• Abstract:
  This report presents the research and results of this study along with procedures for operating the prototypes which were constructed. After careful evaluation, a prototype was constructed using the infrared sensor technology. However, it was discovered that the infrared was too sensitive for use as a remote vehicle sensor. After further investigation, an ultrasonic ranging device was chosen for implementation as an overhead vehicle sensor. A prototype was then constructed and tested under laboratory and field conditions and was accepted as being well-suited for use as an overhead vehicle sensor system. Several more prototypes were constructed and put into operation during the period June 1986 through the present. They operate continuously and their accuracy is checked periodically with traffic counts collected with inductive loops.
