Each unit can perform up to eight studies, plus generate per-vehicle records, with up to 4096 bins of data. This could include, for example, classification by speed, by lane, and volume. The type, configuration, and format of data to be collected can be custom programmed or selected from menu-driven choices. Available data types include per- vehicle records, per-lane data, binned vehicle classification by axle, speed, length, gap, or he adway, or almost any combination of these classifications. Vehicles can also be classified according to either a Scheme “F” or a user-defined classification scheme.
