As more children are exposed to computer science and programming, numerous indicators have been proposed to evaluate programming learning. Because these indicators are not divided by step in a learning goal, learner's growth cannot be evaluated in detail. Our research focuses on resolving this issue in the field of programming. Herein we propose a rubric to measure the progress of programming learning for elementary school students. This rubric, which is comprised of indices, aims to evaluate learning achievement of logical skills such as logical thinking and problem solving using a unified learning goal. Furthermore, this rubric consists of 30 evaluation items in 8 categories. Then we investigate whether this rubric can be adapted to existing workshops of programming learning. The workshops occurred in 2016 and 2017. in addition, A total of 101 students between 6 and 12 years old participated in the workshops. The rubric successfully evaluates programming learning workshops as it provides a unified evaluation that covers common learning objectives in existing indicators. Our rubric is available at https://g7programming.jp/plr/.

Lowering of so-called “rat-run” traffic on community streets has been one of significant challenges for improving the living environment of neighborhood. However, it has been difficult to quantitatively grasp the actual situation of rat-run traffic by the traditional surveys such as point observations. This study aims to develop a method for extracting rat-run traffic based on car probe data. In addition, based on the extracted rat-run traffic in Toyohashi city, Japan, we try to analyze the actual situation such as time and location distribution of the rat-run traffic. As a result, in Toyohashi city, the rate of using rat-run route increases in peak time period. Focusing on the location distribution of rat-run traffic, in addition, they pass through a variety of community streets. There is no great inter-district bias of the route frequently used as rat-run traffic. Next, we focused on some trips passing through a heavily used route as rat-run traffic. As a result, we found the possibility that they habit...
