Digital signage on mass transit is extremely effective because it can be updated up to the moment with advertising and content. It eliminates the high cost of printing and distributing posters throughout a transit system. You can deliver targeted ads that deliver some motion and attract the attention of the passengers. You can use the digital signage to display multiple advertisements to a high-visibility area; with a traditional sign a passenger in the back of the bus or train may miss a static ad placed in the front of the vehicle, whereas rotating signage advertisements reach all riders equally.
A great use of signage on a bus or train would be to provide riders with public information related to route changes, schedule interruptions, and notices that might affect them in their daily routine.
In my experience, digital signage in mass transit works extremely well as a delivery method of content to passengers. Units such as the Ceres 201 work as affordable solutions for mass transit signage that are rugged and can operate on a standard 12V vehicle power supply.
