To explore the driver’s needs of design elements of signs at short-distance continuous ramp exits of the three-dimensional composite expressway. The study road section including the advance area and three decision points, that the 3km advance notice signs, the destination separation information, and the lane guidance information are studied. A demand questionnaire was conducted through the network, and 271 valid questionnaires were collected. The KANO model shows that 3km advance notice signs, the destination separation information at decision points 1 and 2, and the lane guidance signs at decision points 2 and 3 belong to A (charm attributes). The destination separation information at the advance area and continuous setting the lane guidance signs belong to I (undifferentiated attributes). The research results provide guiding suggestions for optimizing the design elements of signs at short-distance continuous ramp exits of the complex interchange.
