| Summary |
Mixed traffic flow of cars and motorcycles is the primary type of traffic flow in Taiwan. This study is aimed at proposing traffic safety improvement measures for accidents in environments with mixed traffic flows. In addition, because the current domestic traffic engineering design reference tool makes it difficult to provide countermeasures for the specific types of traffic accidents at intersections, therefore, this project proposed traffic engineering improvement designs based on the
different kinds of accidents for use in the traffic engineering improvements of specific types of accidents, and a referencemanual of traffic engineering designs for intersections was compiled.
The project was a 4-year plan from 2016 to 2020. In the first year (2017), the design criteria were investigated and traffic engineering designs were proposed for "lane transition configuration near intersections" and "methods for motorcycles to turn left at intersections". In the second year (2018), related designs were established for "signal designs", and in the third year (2019), traffic engineering improvement designs were developed for "ways lanes and alleys join together". This year
(2020), the study focused on reviewing previous research and related materials, verifying the research results of the preceding research, carrying out additional surveys and analyzing changes in accidents and conflicts at intersections of the preceding research, and examining the effectiveness of improvements. Finally, an independent reference manual of traffic engineering designs for intersections was compiled and published on the basis of the various collision types raised in previous research, including sideswipe, rear-end, right-angled and angled collision at intersections, and by summarizing various related designs |
