A Case Study: The Urban Residents’ Choice for Electric Vehicles Warning Sounds

Nowadays, people are exposed to noise on a daily basis. Therefore, in an overvibrant urban environments electrical vehicles operating at low speed are too quiet to be detected by pedestrians (especially vulnerable group are visually impaired people) and urban residents in general. Thus, electric vehicle warning sounds are sounds created to alert and warn pedestrians to the presence of electrical vehicles (e.g. hybrid electric vehicles, plug- in hybrid electric vehicles and all-electric vehicles) moving at low speeds. The goal of this paper is to determine through a case study what the pedestrians would desire and prefer the electrical vehicle warning audio signals to sound like. The case study involved 201 participants who had the task to fulfill a specially designed questionnaire for this purpose. Regarding the questionnaire, the participants were not prepared in any way for the testing they were just advised to keep in mind that the warning sound they select for the “role” of a pedestrian should not be irritable at the same time for the “role” of a driver. The results obtained from the questionnaire were analyzed and discussed in the paper. When speaking about the concept of smart cities and the legislation around the whole world today this is certainly a hot topic where the opinion of pedestrians and future drivers should not be overlooked.
