Abstract
A housing assembly of the apparatus includes a roadway mounted base plate to which a housing is secured with the housing having a low profile and inclined side and end walls to permit placement of the housing assembly along a course of lane markers. The housing defines a chamber in which transducer and electronic components are housed. A collapsible road tube terminates within the housing in communication with the transducer. A retainer prevents road tube separation from the housing. An electrical cable of flat section passes downwardly through the base plate and terminates at a remote tallying component.
Claims4
A traffic counter apparatus actuated by vehicle travel along a traffic lane of a multi-lane roadway, said apparatus comprising,
- a housing assembly including a base adapted for securement to the roadway surface between two traffic lanes, a housing having a low profile to said roadway with inclined exterior walls, means removably mounting said housing to said base, said housing defining a chamber closed by said base and constructed of material to withstand being run over by any roadway vehicle,
- a road tube for disposition in a traffic lane and having an end attached to said housing assembly,
- pressure responsive transducer switch means in said chamber responsive to air pressure changes in the road tube caused by vehicle passage thereover, thereby producing electrical pulses,
- signal transmitting means in said chamber connected to and actuated by said pressure responsive switch means for transmitting said electrical pulses and
- tally means remote from said housing assembly and triggered by said pulses from said signal transmitting means.
