INVESTIGATING EXPERIENTIAL GRAPHIC USER INTERFACE OF SMART CITYENABLED TRANSPORTATION SYSTEM IN LAGOS, NIGERIA

Smart cities leverage information and communication technology to boost operational efficiency, disseminate information to the public, and enhance the quality of government services and the welfare of citizens. Smart transportation is largely anchored in digital devices, which are heavily driven by visual elements. These visual cues include icons, illustrations, colours, typographic contents, menu bars, grids, spacing, animation, avatars, visual selectors, interactive maps, and other visual indicators. The appropriate use of visual cues determines the usability of these technological platforms. This study examines the graphic visual components that comprise the user interface-driven tools enabling the smart city transportation system in Lagos, Nigeria. The research design employed is a qualitative descriptive approach. Data were collected through both primary and secondary sources. The results indicated that user interface tools (ride-sharing apps, traffic delivery reports, and wayfinding systems) are indeed deployed with varying degrees to enhance smart mobility in the Lagos metropolis. Finally, the deployment of the user interface tools needs to be fully optimized to achieve better results.
