摘要： In a vehicle-oriented system (1) for providing information to a vehicle (5) side by using an information providing area (11) provided on a plane where a vehicle (5) moves, a magnetic distribution indicating the information by a plurality of N-pole magnetic markers (10N) is formed in the information providing area (11), and a sign (100) for identifying a position and orientation of the information providing area (11) is provided in the information providing area (11). Therefore, information can be provided by a magnetic method irrespective of a forwarding direction of the vehicle (5).

摘要： A system includes a sensor network comprising at least two optical fibers coupled to a pavement. Each optical fiber includes one or more optical sensors installed a predetermined distance from one or more adjacent optical fibers. The one or more optical sensors are configured to produce a wavelength shift signal. A processor is configured to determine one or both of one or more attributes of one or more objects travelling on the pavement and a traffic condition of the pavement based on the wavelength shift signal. A transmitter is configured to transmit the one or more attributes to a predetermined location.

摘要： In an installation method for laying magnetic markers (10) in a road for driving assist control on a vehicle side, a laying work vehicle (2) sequentially lays the magnetic markers (10) while moving along the road without performing a prior survey or the like of laying positions, and then by using a positioning work vehicle (3) including a magnetic sensor capable of detecting magnetism, the laid magnetic markers (10) are detected and the laying positions are identified to generate position data regarding the magnetic markers (10), thereby allowing reduction of cost of laying the magnetic markers (10).

摘要： An installation system has a laser range finder set at a reference position to measure a distance to a target, an installation cart which performs operation for laying a magnetic marker in a road, and an arithmetic unit which identifies a position relation of a laying position where the magnetic marker is laid with respect to the reference position. When operation for laying the magnetic marker in a road is performed, by taking the installation cart during performing the operation of laying the magnetic marker in the road as a target, based on a distance to the installation cart measured by the laser range finder, the position relation of the laying position with respect to the reference position is identified by the arithmetic unit.

摘要： A speed bump system and method for a roadway that encourages a driver of a passenger vehicle to slow down and that does not substantially impede an emergency vehicle are described herein. The system includes a structure for disposing across the roadway to encourage the driver of a passenger vehicle to slow down before driving over the structure. In one embodiment, the structure has a raised middle portion, a first raised outer portion proximal to one end of the raised middle portion, and a second raised outer portion proximal to the other end of the raised middle portion. The three raised portions are traversable by the passenger vehicle. The structure further includes a first gap between the first raised outer portion and the raised middle portion, and a second gap between the second raised outer portion and the raised middle portion. The width of the first gap, the width of the second gap and the distance between the first and second gaps allow the emergency vehicle to pass through the first and second gaps.

摘要： Speed bumps for mounting across roadway lanes to encourage vehicle drivers to slow down are formed of laminated layers of elongated flexible rubber strips secured together to form a speed bump unit. Typical bump heights of three inches are obtained from six laminated half-inch layers. in one embodiment, layers not exceeding five inch widths cut from treads of discarded vehicle tires between opposing shoulders have a propensity to lie flatly upon a road surface, and are pyramided upwardly by a plurality of stepped layers of decreasing widths thus presenting inclined leading and trailing edges for intercepting the tires of oncoming moving vehicles. In another embodiment curved layers of tire tread strips form ingress and egress edges inclined gradually downward from an uppermost crown to the roadway surface for intercepting the oncoming moving vehicle tires.
