Masayuki Takada,Kazuma Hashimoto,Tamaki Inada,Ki-Hong Kim,Yoshinao Oeda,Yu Chang Lin,Wei Lin, Analysis of drivers' horn use factors at intersections in an urban area of Taiwan, The 49th International Congress and Exposition on Noise Control Engineering, 2020.08, In many countries’ urban areas, noise pollution is produced by frequent use of car and motorcycle horns. It is necessary to clarify the reasons for horn use and propose measures to control it. To investigate the relationships among horn use and such factors as driver awareness, behavior, and vehicle environment, we conducted a questionnaire survey in Taipei, Taiwan. Respondents were asked about their normal horn use, their understanding of the law about such use, their impressions of horn sounds, and their personal attributes. The questionnaire covered the following: intrinsic factors (e.g. attitudes, personal norms); frequency of horn use (i.e. behavioral intention); and judgement about horn use under certain traffic conditions. Our results should lack of awareness about legal horn use. Regarding the relationship between intrinsic factors and behavioral intention for horn use, such factors as attitude, perceived behavioral control, and moral obligation were related to the strength of the behavioral intention to use the horn. Concerning extrinsic factors, logistic regression analysis revealed that speed differences with the vehicle ahead and another car cutting in ahead affected horn use..

The final goal of the present study is to clarify the causes of horn use and to propose a transportation system to suppress horn use. To this end, we have investigated relationships between horn use and factors such as driver awareness, behavior, and vehicular environment. Our previous study investigated causal relationships between horn use and the vehicular environment in Taiwan, and found that horn use was more frequent when gridlock occurred at intersections. The present study analyzed details of gridlock situations at three intersections in Taipei during which vehicle horns were used. We found many cases where honking began after vehicles entered the intersection to turn left during the green-light phase. In particular, drivers often used their horns when they had to wait for more than 4 seconds for the vehicles in front of them to start moving after a green light allowed left turns. Logistic regression analysis revealed that the probability of a driver using a vehicle horn was significantly affected by the duration between the signal turning green and the vehicle in front of them starting to move..
3. Japan has many remote islands in its territorial waters. The isolation yields intense depopulation under aging society in Japan. Improvement of its life surroundings is important challenge for these areas. Some of researches indicate the necessity of the connection to other areas, such as nearby bigger islands or main islands. This study focus on shopping of remote islands residents, especially going out to other areas. This study had a survey in Goto, Nagasaki, and confirmed the resident’s activity to other areas for making up their demand for shopping. Then, to examine the transportation policies and the replacement of shopping facilities, this study built the shopping model that can predict the frequency of shopping in other islands in relation to transportation parameters like travel time. The model showed the good fitness for shopping behavior of residents in Goto ..

7. Benjun HUANG, 大枝 良直, 外井 哲志, 松永 千晶,  Research about Route Guidance by Car Navigation with an Emphasis on Safety and Ease of Driving, 平成26年度土木学会西部支部研究発表会, 2015.03,  With the development of technology in IT, more and more drivers use the car navigation system for setting the trip route. Hence there is need to develop a car navigation system that is consistent with road sign system to reduce this confusion, anxiety situation.In order to search the shortest path, car navigation use different algorithms. The classical algorithm used in car navigation is Dijkstra algorithm. In this research we will use the Dijkstra algorithm. Compared with the traditional shortest path only using Dijkstra algorithm, the improved algorithm with consideringroad sign database and turn will effectively solve the issue ofthe different guidance gave by road sign and the carnavigation..
