ABSTRACT OF THE DISCLOSURE A roll-wound route or destination curtain having multiple different route or destination indications spaced from each other along its length and between its ends, for a bus or other transportation vehicle. Code elements are located at positions along the length of the curtain corresponding to positions of the route or destination indications. A distinctive series of code elements is provided, corresponding to each different route or destination indication along the length of the curtain. Each of the code elements comprises a pair of light and dark segments aligned in the direction of travel of the curtain. Each element of each series has a predetermined function selected from the group consisting of testing, binary code and spacer. The ratio of the width, in the direction of travel of the curtain, of the light to dark segments of each element dictates the function of that element. The route or destination curtain according to the present invention, when provided with an optical position sensor identifying the code elements and transmitting distinctive signals corresponding to the route or destination indication, to a microprocessor, provides a reliable system for automatic route or destination indication in a bus or other transportation vehicle.
