Abstract

This paper is to investigate the auditory recognition distance with several types of vehicles including two types of IC engine vehicle (diesel and gasoline), fully electric vehicle and hybrid vehicle. For this investigation, two experiments were performed. The first experiment was conducted with two low speeds (20 km/h and 30 km/h) on public road similar to proving ground in order to indicate whether a car comes to a subject with two age groups (above and below 60 years old). The second experiment was done on underground parking lot to detect whether there is a car or not when one of the vehicles is under engine/motor idle case. The distance between subject and car is defined as an auditory recognition distance. In addition to the mean value used usually in statistics, the mode value was introduced to represent the typical auditory recognition distance from both sets of experimental data.
