Title: Traffic Flow Detecting Apparatus.
IPC: G08G1/01
Filed: 1967-07-14
Abstract: 1,164,924. Road traffic measurements. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 14 July, 1967 [15 July, 1966; 15 Nov., 1966; 2 Dec., 1966], No. 32624/67. Heading G4Q. Traffic volume is measured by a roadside microphone M feeding a rectifier L connected to an amplitude discriminator the output of which is averaged, e.g. over five minutes, to provide the final output at T. This output may be classified into low, medium and high for controlling traffic signals. The level discriminator S preferably provides a ONE output at each noise peak and a ZERO output otherwise, and may comprise a saturation amplifier (Figs. 5 and 6, not shown). If the microphone is disposed at the centre of a controlled cross-roads, the output of the level discriminator circuit may be fed additionally to two further averaging circuits (A1 and A2. Fig. 9, not shown) via a switch operated synchronously with the traffic signals; in this way separate outputs are derived for North-South flow and for East-West flow as well as an output for total flow. When two microphones are disposed on opposite sides of a road (Fig. 10, not shown) for measuring traffic in both directions of flow, the same noise may be recorded by both detectors; this may be avoided by a comparator (C, Fig. 11, not shown) which disables the level discriminator in the channel with the smaller signal level. In a more elaborate arrangement, Fig. 12 (not shown), there are a plurality of comparator units each supplied through filters from the microphone outputs, and a logic circuit (L) for utilizing the outputs of the comparators to disable one or other channel under prescribed conditions.
