Wireless digital signage for intelligent traffic management system

Abstract

Wireless digital signage for intelligent traffic management system is an integrated system for traffic management purposes. Digital signage, which is made out of LED matrices, is used to display real-time traffic information sent from the police or other traffic authorities wirelessly and mobile. To show information as a real-time, it is required a system of wireless networks which is able to transmit the information quickly and actual. On a small scale, this wireless system is divided into two, delivery data that carried out by the user through the application and acceptance of that which is received by a hardware display at a same local network. The data delivery can be carried out by applying the principle of a socket programming between users as client with a hardware device on display as the server. To ensure the delivery is reliable, socket used the principle of communication through the TCP/IP. On a large scale, this network system is the integration of small scale network subsystem which every subsystem is connected by using a WiMAX network. It is intended in order that information on traffic conditions that occur can be affordable in many locations as a real-time. To be able to updates information about traffic conditions in real-time, it required mobile devices that can manage the content of the information, therefore it needs a software applications that can run on android and PC so police or authorities can update information quickly. Applications on mobile devices can access multiple digital signage displays that are scattered in various locations and also show the status of each display, whether it is online or offline. © Springer-Verlag Berlin Heidelberg 2014.
