Abstract
The “RER line E” spans Paris area, with 35 stations. This project aims to create a unique sonic design in the train using auditory icons to connect each station with its history and regional characteristics. It helps commuters, visually impaired individuals, and visitors detect stations, reducing mental load and enhancing inclusivity.
Description
“Eole” is the largest current project of the French railways (SNCF) and the showcase of Mass Transit in Île-de-France area. It involves the extension of the RER E (Regional Express Rail Network) to the west, with a first phase scheduled to be operational in May 2024. With next-generation rolling stock, the RER-NG, this line will ultimately transport 620,000 passengers who will benefit from significant time savings. Anticipating in the industrial development process of rolling stock, exchanges between “SNCF Voyageur” and STS allowed for the development of a specifications document on the concept of onboard sound design, linked to inclusivity, accessibility, and line identity.
According to the operator, the project’s objectives and requirements were as follows:
• Anticipate and streamline platform/train exchanges.
• Establish unique landmarks at each station for regular customers.
• Surprise occasional customers by offering a positive onboard experience.
• Develop the line’s identity.
The contribution of sound design has allowed us to go further. Following the results of previous analyses and projects on visual impairment and hypersensitivity in public transportation conducted by STS, we knew that the challenge was actually to promote universal access to transportation for all populations and facilitate understanding and movement for everyone, regardless of their level of cognitive ability. The development of ‘auditory icons’ for each station in the transportation line was meticulously undertaken to ensure seamless integration and understanding. Longer versions have been developed to symbolize the terminus.
Through thorough research and collaborative efforts, a diverse range of elements representing the cultural, historical, and social aspects of each territory were identified. This involved conducting interviews, historical research, and consultations to create a comprehensive list of elements. Establishing a common vocabulary for describing sounds posed an initial challenge, necessitating the development of sound textures and logic for ‘soundals’. With a validated set of sound materials and shared vocabulary, creative work commenced.
After extensive iterations and feedback sessions with both professionals and users, the final sounds were tailored for optimal in-situ perception. Additionally, a ‘micro sound logo’ was crafted to anticipate and enhance passenger engagement. A lengthened version of this is heard at each line junction to maximize the understanding of the route for the visually impaired and to capture everyone’s attention. Evaluation by daily users indicated a high level of satisfaction, with 75% finding the sounds representative of the territory, 67% believing it enhanced the line’s value, and 65% feeling a greater sense of personalization in their journey. This meticulous approach to auditory design significantly enhances the overall travel experience, ensuring inclusivity and engagement for all passengers.
