<![CDATA[Jakarta and its surrounding supporting cities are intertwined with the electric train transportationsystem known as the Jabodetabek KRL. In using this rail-based mass transportation facility, currentusers/prospective users are assisted by wayfinding information signs in the form of a diagrammaticmap of the Jabodetabek KRL route. One of the official route maps currently in use is the four-way(north-south, east-west) route simplification map. As a result of the simplification of the visualizationof space and distance, navigation confusion occurs on the map, where the positions of station points /between stations and geographical locations are very inaccurate / far from the actual spatialconditions. This of course will distract the basic ability of the user's spatial cognition. This study triesto explore the problems of visual perception and non-verbal communication between users (assubjects) and currently used KRL information signs (as objects) that occur as a result of the variety andmethod of visualization. Using the method of direct observation of the object under study andcomparing it with the spatial conditions of the official geographic map of Jabodetabek, then proceedwith a confirmation process to users (respondents) regarding the misperceptions that have occurred.The results of this study are expected to provide input to the designer of the Jabodetabek KRL routediagram map to pay attention to the fundamental problems of opportunities for misperceptions thatoccur and to improve the communication presentation in the next publication of the route diagrammap.]]>
