摘要： A link travel time calculation device includes: a collection element for collecting a travel position and a transit time in each vehicle; and a link travel time calculation element. The calculation element calculates a total travel time interval of all sections based on the travel position and the transit time in a predetermined time period. The calculation element calculates a first travel time interval of an upstream section and a second travel time interval of a downstream section based on the travel position and the transit time. The calculation element calculates a travel time interval of the object link with respect to the predetermined time period by subtracting a sum of the first travel time interval and the second travel time interval from the total travel time interval.

摘要： A directional beam antenna device includes: an antenna supporting member which is supported on a base in such a manner as to be rotatable about a first rotational axis; an antenna portion which is supported on the antenna supporting member in such a manner as to be rotatable about a second rotational axis which is perpendicular to an antenna aperture and is inclined at a first angle with respect to the first rotational axis, the direction of an antenna beam being inclined at a second angle with respect to the second rotational axis; a first driving unit for rotating the antenna supporting member about the first rotational axis with respect to the base; and a second driving unit for rotating the antenna portion about the second rotational axis with respect to the antenna supporting member. A directional beam controlling apparatus is provided with a controlling unit for controlling an elevation angle of the antenna beam to a target value by causing the second driving unit to rotate the antenna portion with respect to the antenna supporting member, and for controlling an azimuth angle of the antenna beam to a target value by causing the first driving unit to rotate the antenna supporting member with respect to the base.
