Reducing Congestion Through Visualization

Urban motorists benefit daily from sophisticated traffic monitoring and control systems. Most major cities have become virtually impenetrable because of heavy traffic conditions. To combat this problem, improve safety on the roads and reduce air pollution, cities are equipping their road traffic controllers with visualization systems like those built with ILOG software.

Visualization solutions powered by ILOG clearly and accurately display the flow of automobiles through the cities and surrounding areas. Information such as number of vehicles, average speed and road conditions are shown in a map-based display. Controllers can make quick decisions, using signaling systems -- stoplights and information boards -- to manage traffic glow to prevent or reduce road congestion and air pollution, moving cars through areas faster.

Real-time monitoring
Today's road traffic controllers need highly reliable and intuitive graphical user interfaces (GUIs) that enable real-time monitoring of traffic and on-screen interaction with data sources and signaling equipment. These GUIs must consolidate information, taking data from diverse sources -- sensors, cameras and databases, for example -- and display it in a well-organized, highly ergonomic graphical environment. The traffic controller needs to be able to spot potential congestion points and immediately take steps to prevent traffic jams from occurring.

Fully interactive displays
Major cites around the world have adopted ILOG visualization technology to manage traffic in real time. ILOG supplies everything necessary for quickly building fully interactive GUIs.

• Industry-specific graphic objects
  ILOG provides a way to quickly and easily implement industry-specific graphic objects and behaviors. Users need only import and connect a graphic object in order to use it. This simplifies and expedites development by eliminating the need for research and design work to create a graphic for a project.
• High-performance display engines
  ILOG visualization engines are among the fastest on the market, ensuring real-time display whenever possible.
• Unparalleled development tools
  The developer gets a complete set of graphical editing and deployment tools. The tools enable the user to fully modify a graphic object, add it to a display and connect it to a data source.
• Maps and mapping tools
  To fully comprehend the flow of automobile traffic, a controller must see traffic displayed in a map. ILOG provides an entire visualization system devoted to enhancing GUIs with cartographic information. The system includes maps of regions throughout the world.
• Connectivity
  With ILOG Server, ILOG ensures every computer running the same display system gets the same picture. ILOG Server keeps vastly removed computers in sync by automatically updating data across networks
.
• Gantt chart and other standard diagrams
  ILOG provides graphs and diagrams used throughout the industry to display key information in a logical, easily understood manner.
• Full compliance with other systems
  ILOG software is designed to work with all the leading systems. It easily integrates with systems from across the entire industry.
• Web support
  All ILOG software fully supports Web-based applications. Key road-traffic control systems have been made Web-accessible with Java visualization from ILOG.
