Abstract

This article outlines a mechanism to provide bus status and route information to bus stops where power and networking are not available, or cost effective to install. It covers the embedding of electronic shelf labels into a bus stop and using buses passing the stop to update the information on the shelf label with information regarding the status of the next bus due to visit the stop.

Updating location sensitive displays by using roaming third parties knowledge of the entire system

It is becoming common place for users of a service to expect smarter, accurate location data to be made available with respect to a service they are using or intend to use. For example it has now become accustom for passengers of a train/bus/tube to be made aware of how long it is until their service arrives via electronic signage displayed on a platform/bus stop. Current signage requires access to electricity and a data connection to allow streaming of realtime updates as to the location of these services.

    Although this is cost effective when implemented at hub locations such as major bus terminals and train stations, this approach is not sufficient to be used in scenarios where minor stations do not have access to readily available electricity and a data connection. A good example of this is in the usage of minor bus stops consisting of just a sign.

    This disclosure aims to protect a mechanism whereby location based data for a service can be displayed to an end user, via other non related roaming entities. The advantage of this approach is the signage can become a dumb display, requiring low power and no fixed data connection. The dumb display is updated with data via other roaming entities within that service, crucially the information that is updated is not related to the roaming service but is related to other services within the same domain as the roaming service.

    The mechanism defined here provides a cost effective way for service information to be presented to users where power and a data connection is not available.

    This publication has a number of different applications, in this example we will be describing the implementation for a bus service,however this disclosure should not be limited to that implementation.

    A rural bus stop serves bus routes 5 and 7. It's location is such that to run a power supply and a data connection to that stop to provide location data of the services is not cost effective. The bus stop itself is embedded with a device similar to an electronic shelf label (hereafter referred to as low power display device)

    Each bus is already in communication with a central server via a data link and is able to pass information from the server onto the low power display device. As each bus passes the bus stop the low power display device is updated from the bus with data from the bus companies central database. The information that is sent to the low power display device provides an update as to the ETA of the next bus due at that stop. The fact tha...
