Measurement of Motor-vehicle Traffic Volume Using Camera Images and Artificial Intelligence

by Ryuichi Imai - June 5, 2022

In Japan, road traffic censuses are conducted to assess road traffic conditions. Recently, techniques for counting traffic volume from video images have been attracting considerable attention in order to improve work efficiency and save labor, and a large number of technologies have been developed. However, since traffic volume surveys are often conducted 24 hours a day, day and night, at various sites and under various weather conditions, existing technologies have yet to reach the counting accuracy required in practice. The authors aim to develop techniques for traffic volume surveys applicable in practice by applying artificial intelligence. This paper reports the results of a case study in which the proposed techniques were applied to the video taken during actual traffic volume surveys.

Nature Versus Artifact Body II:Sollen, Central Dualism, and Chameleon Criteria

by Masayuki Matsui - December 12, 2022

Contrary to Wiener’s work, the subject of Sein and Sollen in “nature versus artifact bodies” was logically re-examined using a white-box (pair-matrix) approach and formalized on pair-map (microcosm) under closed-earth versus smart-world conditions. This body science and Sollen of 3M&I variety (pair-map) would be probably developed at the type of ternary SW, which resembles the Eastern danshari concept, and is likely due to the motion–energy dualism under Newton’s laws (analog type), or equivalently, the amount–value dualism under Matsui’s law and dualism (discrete type). For this body’s central dualism, a pair map (rotational phase) was characterized in 1983 based on the microcosm of cross-ellipse images in a matrix of input–output pairs. At the paper, this field theory is physically formulated, solving the pair matrix, ternary SW and its central dynamism in a body of input-output. The observed underlying condensed structure (time model), and the internalized (embedded) dynamism (fractal and wave motion equations), are numerically clarified based on the expansion of the corporate-producing entity pair maps in Matsui’s theory. Furthermore, it is demonstrated that the center of the pair-map hyperplane corresponds to a black hole (manifesting in the form of a conical dip that warps spacetime), collapsing the artifact bodies. Finally, interesting issues and findings are reported regarding the central dualism, progressive physics and chameleon criteria (medium), and are related to pair-map.

3D Point Studio: Utilization Platform for Point Cloud Data

by Kenji Nakamura - August 4, 2022

As Laser measurement technology has made remarkable progress in recent years and the means of measuring the three-dimensional shapes of road spaces as point cloud data have diversified, point cloud data has been measured and accumulated throughout Japan. Point cloud data is useful as a means of accurately grasping the present shape and is expected to be utilized for a wide range of purposes with i-Construction as a turning point. Existing efforts have promoted development of new technologies and open data, steadily increasing opportunities to use point cloud data. However, it is difficult to use point cloud data wisely in accordance with its intended purpose because it is merely a vast set of points that indicate locations in space and does not hold information about the features indicated by the points or about their relationships to other points. Therefore, it is essential to develop an environment for utilizing point cloud data. In this study, we develop 3D Point Studio, a platform for utilizing and sharing 3D data including point cloud data by utilizing area data. The usefulness of this research will be confirmed through examples of applications in the actual sites, and its future development will be discussed.

Creating a scale for measuring non-cognitive abilities developed through sports for elementary school students

by Keita Kawazu - September 20, 2022

The purpose of this study was to create a scale to measure non-cognitive skills that can be developed through sport. To begin, a draft of a non-cognitive ability measurement scale was developed based on previous research. A preliminary survey of 346 elementary school students (318 males and 28 females, mean age 8.90 ± 1.76 years) was conducted, and a preliminary scale was created using exploratory factor analysis. A subsequent main survey was conducted with 1171 elementary school students (1025 males and 146 females, mean age 8.77 ± 1.73). In the present study, confirmatory factor analysis, reliability testing using cronbach's alpha, and structural validity of the entire scale were examined using structural analysis of covariance. Furthermore, theoretical interpretations were also taken into account, and finally, a non-cognitive ability measurement scale that can be developed through sports for elementary school students was created, consisting of 50 items with 5 factors: "self-management," "problem-solving," "cooperativeness," "leadership," and "greetings/polite".
