    • PROBLEM TO BE SOLVED: To provide a device for measuring a road-surface roughness distribution wherein the partial rough distribution of a road surface is acquired. SOLUTION: A device for measuring a road-surface roughness distribution is provided with an antenna 13 which emits a measurement wave 11 toward a road-surface 12 and receives a scattering wave which is generated when the measurement wave 11 is reflected on the roughness of the road-surface 12 and scattered, rotating means 20 and 21 which rotate the antenna 13 in the plane orthogonal in the emission direction of the measurement wave 11, a transmitting/receiving means 16 which generates and amplifies the measurement wave while amplifies the received scattered wave, a processing means 22a for processing the scattered wave amplified by the transmitting/receiving means 16, a storage means 22B which stores the result of the processing means 22A while related to the rotation angle of the antenna 13, and a parameter formation means 23a wherein the stored content in the storage means 22b is compared with a pre-set content to calculate the compared result for forming a parameter related to a road-surface roughness distribution.

    • PROBLEM TO BE SOLVED: To distribute only optimum information in consideration of position relation and to prevent traffic from increasing by judging the level of information from position coordinates included in received information and the position coordinates of the system itself.
      SOLUTION: Of the information communication device 100, a sensor processor 120 gathers and processes information from sensors 110 for monitoring and grasping the state of a road. A controller 130 performs information processing and communication control of the whole information communication device 100. At this time, it is important to identify the occurrence position of an occurring event, the positions, etc., of the information communication device 100 and a vehicle, and the position and distance of information transmission and reception and X and Y coordinates or two-dimensional coordinates of longitude and latitude are used. After a sensor processor 120 processes the abnormal occurrence event on or nearby the road which is detected by the sensors 110, the controller 130 sends data to a central communication system 500 and also informs nearby vehicles 310 and 320 of the abnormality through a radio line 400 by a radio communication device 140 and an antenna 150.
