摘要： PROBLEM TO BE SOLVED: To efficiently collect road information such as an accident from general people by using a portable telephone set with GPS or a communication-type car navigation system.
SOLUTION: When a user of a traveling vehicle detects occurrence of an event such as the accident or a fallen object, the user transmits positional information by GPS and information on the accident or the like to an information collection center 2 by using the portable telephone set with GPS 1 or the communication-type car navigation system. The information collection center 2 analyzes received data, estimates a position and directs a patrol vehicle 3 to take a countermeasure. When transmitted information is correct as a result of the countermeasure, a procedure of acknowledgement is performed from the users who have transmitted the information to a selected user. Thus, much information can speedily be collected, correspondence to the accident and that to the fallen object can speedily be performed and secondary disasters can also be prevented.

摘要： PROBLEM TO BE SOLVED: To form an appropriate road repair plan to efficiently repair parts to be repaired with appropriate timing. SOLUTION: A repair/inspection plan forming device 20 forms an inspection plan, based on the previous inspection history of a recording device 26 and sends the plan to an inspection terminal 2. Based on the inspection plan, the inspection terminal 2 inspects a road using a camera 4, a microphone 5, an acoustic sensor 6 and a vibration sensor 7, to see the state of its deterioration. The result of the inspection is sent to the repair/inspection plan forming device 20. The repair/inspection plan forming device 20 classifies the degrees of road deterioration, based on the inspection result, anticipates the future tendency of the road to deteriorate, and presents a plurality of repair plans about parts to be repaired, time of repair, and the scope of repair. A road manager finally selects the repair plan. Rules about construction processes, materials and equipment, and allocation of personnel for achieving the repair plan selected are extracted from a database and to the road manager is given navigation for the implementation of road repairs.

摘要： PROBLEM TO BE SOLVED: To automatically adjust the communication area of a radio antenna in an automatic nonstop charge reception system. SOLUTION: Control radio waves 11 transmitted from the radio antenna 1 installed at a tollgate are received by measuring devices 2, 3, 4 and 5 installed at the boundary of the communication areas of lanes. A communication area position judging device 6 judges whether or not the measured value D of the measuring device 5 arranged in the X axis direction of the measuring device 2 satisfies an allowable value when the measured value A detected in the measuring device 2 is less than the allowable value set to the communication area and moves the communication area in the X axis direction at the time of satisfying it. A processing is similarly performed for the measuring device 3 arranged in the Y axis direction of the measuring device 2 as well. When the measured value D is less than the allowable value, the deviation Δ of the true value and the measured value of the respective measuring devices 2 and 5 is obtained and the communication area is moved in the positive direction of an X axis in the case that ΔA is larger than ΔD and in the negative direction of the X axis in the opposite case.

摘要： PROBLEM TO BE SOLVED: To provide a mobile communication system where the start of communication between a mobile station and a stationary station is quickened and a key in use is quickly and securely switched against an illegal use of an encryption key or the like. SOLUTION: Common keys with plural versions are available for encryption communication between a stationary station and plural mobile stations, each mobile station 1 manages a sole key version and its symmetrical key (ordinary key and emergency key) in a form of key information DB 6, and the stationary station 2 manages plural key versions and their symmetrical keys in a way of key information management DB 12. The mobile station 1 sends a key version of its own station on a communication request, the stationary station 2 discriminates whether or nor a usual key of the received key version is effectively supported and replies the version and the key application (normal), when it is effectively supported. When the usual key is invalid, the stationary station 2 replies the version and the key application (urgent). The mobile station 1 discriminates the key version and the key application replied from the stationary station 2 and switches the key used by its own station into the urgent key, even if the key version is the same when the key application is the 'urgent key'.

摘要： PROBLEM TO BE SOLVED: To make freely distributable computational resources by determining the number of elements of a prior computational table independent of the bit length of a multiple determined from a system request. SOLUTION: When a multiple K (n bits) and a number w of elements are given, a bit extending section 2 obtains a minimum integer m which is an integer not less than n and is a multiple of w. When m is >n, an extending multiple K' is obtained by adding (m-n) bits of a value '0' to the upper portion of the multiple K. Then, in a prior computing table 1, 2W prior computational data are prepared for the number of the elements, the table is referred by the address generated from the coefficients of the multiple K', the data are taken out and a power multiple computation is conducted by a computation section 5.

摘要： PROBLEM TO BE SOLVED: To re-display a simulation of a traffic flow simulation device. SOLUTION: A traffic flow simulation device stores a halfway operation situation of a simulation displayed on a display means 900 in a storage means. The storage means stores each operation situation simulated in each prescribed time division corresponding to order information representing the order of the simulation performed. Moreover, a start command 903 accepts the start of a simulation, and a stop instruction command 904 accepts an instruction to stop the simulation. When a successive return command 906 is instructed, an operation situation is re-display in a reverse order of the order information. Further, when a successive advance command 911 is instructed, the operation situation is re-displayed in order of the order information.

摘要： PROBLEM TO BE SOLVED: To provide a method for generating a simulated marine wave image which is expressed by a triangle wave mesh and is rich in reality and by which a high speed processing can be performed. SOLUTION: The initialization of a field of vision range is performed according to a field of vision range height h from the surface of the sea (100), each intersected point (x, y, and z coordinates, z-0) of a three-dimensional mesh extending to the field of vision range is calculated (101) and each intersected point is stored in a mesh data storage part. The quantized data of 'fluctuation' modulating the quantized data of the wave height pattern changing by a sine wave and as wave pattern according to the time lapse is calculated and is made into a table (103). After the initial data of an image display such as a range of visibility, etc., is inputted, a wave height calculation is started (300). At first, the x and y coordinates of each intersected point is converted into the X and Y of a word coordinate system (301). Based on the X and Y, the quantizied point of the wave pattern and the quantized point of fluctuation are determined (302 and 303). The wave height synthesizing retrieved table data is imparted to a Z coordinate (304).
