Study on the occurrence of horn and traffic environment in a major intersection in Taipei City

Abstract

Examining the cause of car horns can lead to improvement of environmental problems, road structure and operation in car traffic. In this study, in order to evaluate the laws, regulations, road structure and operation methods on automobile, we selected a different country form Japan, Taiwan, investigated the occurrence of the horn with traffic conditions at intersections in Taipei city, and analyzed them from several viewpoints. First, we grasped the relationship between the total traffic volume and the number of the horns. After that, we picked up one of patterns of “vehicle interruption to other”, and analyzed this pattern to find out influential factors to cause the horn under the traffic conditions. As a result, from the first part, the number of horns generated increases in a certain traffic volume range. In the second part, it was shown that the horn occurrence rate on “vehicle interruption” is affected by the speed gap between two cars and interrupt direction of maneuvering car.
