RemoteFlash - Traffic Control

World-wide traffic management systems regulate street traffic,  railway transportation, shipping and air traffic. Cooperating electronic control units meter, control, diagnose and manage a total system for modern adaptive traffic control, and for that purpose they exchange data with eachother. Controllers herein are responsible for the data flow between control centers, detectors, and sensors/transmitters.

The area of application for software-driven controllers in traffic control is manifold. From pedestrian traffic lights via medium-sized crossings up to highly complex and networked control units at traffic junctions and hubs. Working in combination with systems for traffic surveillance and simulation and/or systems for meteorologic data compilation traffic control must be considered as a highly complex and modular expandable data network.
The goal of interaction of such a lot of components is effective and coordinated traffic operations for best capacity utilization/load of the traffic infrastructure. Additional aspects to be ideally achieved are minimization of the energy consumption and minimum waiting times due to stop and go conditions. Amongst others the following procedures are invoked:
  • load-dependent program selection for traffic lights, e.g. progressive signal system,
  • in addition, particular signals could be influenced, e.g. green periods in the time of circulation and phase sequence adjustments,
  • definition of increased speed lanes for public transportation,
  • tunnel control and adaptive lane assignment,
  • integration of car-park routing systems and
    maybe even
  • the brightness of environmental lighting to be tuned.
In order to do the adaptive traffic control with orientation towards the overall traffic situation and expectable circumstances these components are combined with strategic units as well, e.g. automatic permanent counting points, strategy detectors, video cameras, theoretical traffic models and simulations.

Often high costs for maintenance are raised in such complex networks where each component must rely on the others. All control units more or less dependent on others, and it is most important to have all controllers fulfill the latest state of the art. Thus, it is a clearly understood demand that controllers must be updated to new, corrected software on demand. New formal definitions may require changes on the controllers as well. And so, this maintenance process typically takes a lot of money for technical personal on side.



The adisoft solution is based on a special and secure wireless data transmission mechanism for mobile software distribution to real-time controller networks in traffic control systems. It is completely free of any dependencies from network operators and providers as well as from the type of physical data transfer media. 

Concurrent and "silent" software updates can be run and controlled by a central backoffice update unit for all concerned controller devices. No technical service is required on-site any more. The delivery of the software updates is carried out via some available wide-area network, e.g. available cable networks and/or mobile and wireless networks like WiFi, WiMAX, UMTS/HSDPA, GPRS, CDMA2000 or GSM. The whole maintenance process is optimized; and cost reductions up to 75% can be achieved.

The design of this innovative remote maintenance solution based on mobile networks covers all specific requirements from highly secured data transfer up to real-time flash updates and roll-back to earlier software releases in case of errors during automatic system checks.
