Kanban and its information display method.

At present, the general traffic information presentation method is that the government transportation department fixedly erected the road traffic information at the ramp or at an important intersection. For the passers-by who have not yet passed through the kanban erection area, it is impossible to obtain the required information in advance and immediately. Traffic information, so the release of traffic information is not efficient. On the other hand, with in-vehicle equipment for GPS positioning and wireless communication, passers-by can get instant and on-the-spot traffic information, however, in the release of traffic information (short travel time) and cost (including the purchase and service of in-vehicle devices) This instant traffic information service is a barrier to popularization when the ratio of maintenance and communication costs is poor and the software and hardware standards of the telematics platform (including the front and back of the network) are not yet complete.

In terms of vehicle body broadcast information, passengers and pedestrians are currently mainly targeted for service, while information content is mainly commercial advertisements, such as bus body advertisements or advertising vehicle bodies and voice advertisements. Taking the bus as an example, in the case of in-vehicle advertising, the fixed advertisement generally located above the seat has a small display area and monotonous information content, so the benefit is limited, and the dynamic advertisement using the electronic display screen is limited by the interior space and the display device. Technology, the display panel can only be placed in a fixed location, and the broadcast effect is easily affected by the change in the number of passengers. In terms of off-vehicle advertising, the main target of advertising is mainly waiting passengers. Therefore, it can only have better advertising effects when the vehicle stops. On the other hand, taking advertising vehicles as an example, the appeal of advertisements is for home residents or pedestrians who move slowly. Therefore, advertising vehicles often drive at a slow speed to achieve their broadcast effects. However, the right to use passers-by is easy. Suffered from violations.

As far as the business model of information broadcasting is concerned, commercial advertising information is a disgusting message for most users who receive broadcast messages. However, pure subscription information services cannot obtain the necessary costs for broadcasting service operations. Therefore, subscription information and commercial advertising must be balanced in order to coexist.
