Four systems are available, programmable to classify vehicles to the FHWA scheme. In a study conducted by the Main Facility (Lyles, Wyman; July 31, 1982; Evaluation of Vehicle Classification Equipment) a scheme "E" was selected from five candidate schemes and recommended to the FHWA for adoption as a standard. In order to correct logic errors in that scheme and to add categories for mototcycles and buses the classification scheme "E" logic has been changed and a new scheme called "F" has been evolved. This scheme "F" has been evaluated and appears workable as a classification scheme at about 95% classification accuracy. The I.R.D. unit is a permanent all weather system. The Golden-River unit is a semi-permanent, clear road system only. The Streeter-Amet unit and the G.K. Inst. Units are clear road systems using pneumatic tubes only. The fifth system tested, a Sarasota unit classifies by road loops to 7 length categories only. Sarasota expects to have the same electronic package operating from road tubes with scheme E or F programs available after January, 1985. All systems operated satisfactorily during the three month test period within the limitations listed under the Detailed Evaluation. (Author) Evaluation. (Author)
