    • A motorized traffic-way controller wherein a retractile tire barrier and opening gate barrier are coordinated to operate in unison by a motor drive that is recycled by closing a mode switch through cam controlled "stop" and "go" switches responsive to the position of the motor drive, the installation being above grade with low profile modules having retractile tooth configurations that projects for tire damage, and with a signal barrier supported by a drive unit at the side of the traffic-way and in the form of an arm that is lifted when the tooth configuration is retracted, the modules and drive unit being adapted to coupled engagement one with the other when assembled.

    • The method of arranging a row of tire sensing devices across about half a traffic lane, arranging the devices into groups whose length is no greater than the difference in width between the narrowest dual tire to be detected as such and the widest single tire to be detected as such, arranging the groups into a series of blocks each containing N groups producing a first output indicating that a tire has passed whenever a tire encounters any one of the sensing devices, and producing a sound output indicating that the passing tire is a dual tire whenever the tire has encountered a sensing device in each one of a first, second, and Nth group of devices.
    • 将一排轮胎感测装置布置在大约半个行车道上的方法,将这些装置布置成长度不大于要检测的最窄双胎之间的宽度差和要检测的最宽单个轮胎之间的宽度差异的组 因此,将组布置成一系列块,每个块包含N组,产生指示轮胎在遇到任何一个感测装置时轮胎已经通过的第一输出,并且产生表示通过轮胎是双轮胎的声音输出 每当轮胎在第一组,第二组和第N组装置中的每一个中遇到感测装置时。
