THE DEVELOPMENT OF SIGNAGE SYSTEM OF THE SAEN SAEP CANAL BOAT TRANSPORTATION TO SHOW THE IDENTITY OF THE SAEN SAEP CANAL

Abstract

This research aimed to develop a signage system for Bangkok’s Saen Saep Canal passenger boats, which serve as a vital water transportation network in the city.  The objectives were threefold: first, to develop a signage system that reflects the cultural identity of the Saen Saep Canal; second, to improve the public perception of this water transportation network; and third, to communicate travel information to users through contemporary, effective design. The research sample was divided into 2 groups as follows: Group 1 consisted of 50 participants residing in the area along the Saen Saep Canal, specifically between Phan Fa Lilat Pier and Wat Sri Bunruang Pier. Data were gathered using a questionnaire that assessed participants' perceptions of the canal's cultural identity. Group 2 consisted of 100 passengers of the Saen Saep Canal boat service. Participants assessed the prototype signage system using a satisfaction questionnaire to evaluate the design developed in this study. The research findings revealed three key elements of the Saen Saep Canal's cultural identity. The cultural blend of Islam and Buddhism ranked first, followed by the ethnic diversity of residents living along the canal, and the canal's extensive length. Architectural elements from two religious sites located at Saen Saep Canal piers informed the signage system design: Ban Don Mosque, representing Islamic architecture, and Wat Sri Bunruang, representing Buddhist architecture. These structures were analyzed to establish design guidelines that reflect the canal's cultural identity. The design elements were straight lines, curves, triangles, lines with intersections and clear directions for leading the eye. The layout was balanced and symmetrical with composition and visual symmetry. There were a clear emphasis and gradation in the layout of the elements. Five types of signage systems have been developed: pier name signs, pier notification signs for passengers indicating the name of the next pier, signs showing information about boat routes, signs showing information and fares, and port image symbols. The overall evaluation results of all aspects of the entire signage system for passenger boats on the Saen Saep Canal, including all types of signs, received the highest satisfaction score of 4.55. Three key aspects were evaluated in order of satisfaction scores. The highest-rated aspects (mean = 4.69) were promoting the passenger boat service's image and communicating travel information. Representation of the canal's multicultural identity, specifically the Islamic-Buddhist blend, scored moderately high (mean = 4.46). Aesthetic appeal and design uniqueness received the lowest satisfaction rating (mean = 4.35).
