Abstract: Provided is a multilayer precast paved road that enables simple coupling between upper pavement panels and lower pavement panels using joint members and enables easy and quick assembly and removal without requiring a large number of processes. A multilayer precast paved road including a plurality of precast lower pavement panels laid on a road panel and a plurality of precast upper pavement panels laid on upper surfaces of the lower pavement panels is configured such that the lower pavement panels 3 and the upper pavement panels are arranged in a zigzag manner, and joint members are provided to lie between upper and lower joining surfaces of the lower pavement panels and the upper pavement panels, and the lower pavement panels and the upper pavement panels are coupled to each other through engagement or fitting between the lower pavement panels and the upper pavement panels achieved by the joint members.

Abstract: A paved structure capable of feeding power to a traveling body in a noncontact manner. The paved structure feeding power to a power receiver provided in a traveling body through an electromagnetic wave, includes: a depression extending in the direction in which the traveling body runs; a magnetic member laid in the depression; a power feeding body laid on the upper surface of the magnetic member to feed power to the power receiver through an electromagnetic wave; and a power feeding body protector laid in the depression to cover the power feeding body.

Abstract: A trough used for feeding power to a traveling body in a noncontact manner, a paved structure, and a method of constructing the paved structure. The trough used for a paved structure feeding power to a power receiver provided in a traveling body through an electromagnetic wave, includes: a trough body having a trough depression extending in the direction in which the traveling body runs; a magnetic member laid in the trough depression; a power feeding body laid on the magnetic member to feed power to the power receiver through an electromagnetic wave; and a power feeding body protector laid in the trough depression to cover the power feeding body.

Abstract: The present invention provides a trough used for feeding power to a traveling body in a noncontact manner, a paved structure, and a method of constructing the paved structure. The trough 1a used for a paved structure 5 feeding power to a power receiver provided in a traveling body 2 through an electromagnetic wave, includes: a trough body 10a having a trough depression 100 extending in the direction in which the traveling body 2 runs; a magnetic member 11 laid in the trough depression 100; a power feeding body 12 laid on the magnetic member 11 to feed power to the power receiver through an electromagnetic wave; and a power feeding body protector 13 laid in the trough depression 100 to cover the power feeding body 12.

Abstract: The present invention is to provide a paved structure capable of feeding power to a traveling body in a noncontact manner. The paved structure 1 feeding power to a power receiver 3 provided in a traveling body 2 through an electromagnetic wave, includes: a depression 10 extending in the direction in which the traveling body 2 runs; a magnetic member 11 laid in the depression 10; a power feeding body 12 laid on the upper surface of the magnetic member 11 to feed power to the power receiver 3 through an electromagnetic wave; and a power feeding body protector 13 laid in the depression 10 to cover the power feeding body 12.

Abstract: A hazard perception test system comprising a CRT screen for displaying a sequence of images of a scene to be viewed by a test subject and in which at least one hazard appears, the images establishing a state of relative movement between the at least one hazard and the test subject, a computer for generating a select signal in response to an action by the subject, the select signal representing an image in the sequence selected by the subject as a point in the sequence at which to change the state, and for determining the ability of the subject to satisfactorily perceive hazards on the basis of the select signal.

Abstract: A control system is provided to enable pavement line marking apparatus to refurbish old lines on a pavement surface. The control system has at least one old line detector adapted to scan a predetermined width of the pavement surface while being carried forwardly along the pavement. The old line detector is capable of recognizing old line pattern transition points as taught by a neural network and in response to such recognition, control activation of new line material applicators to repeat accurately said line pattern changes.

Abstract: A removable barrier adapted to co-operate with a concrete median barrier of a roadway to form, in situ, a barrier between a vehicle travelling in one direction on the roadway and a vehicle travelling in another direction, wherein:the removable barrier is adapted for movement such that, when desirable, the vehicle travelling in the one direction can transgress the barrier and travel on the opposite side of the roadway, and further whereinthe removable barrier comprises at least one shell conforming substantially to the outer shape of the concrete median barrier and is adapted for sliding movement relative to the concrete median barrier.
