Traffic Control GUI Modernization

A traffic control systems provider needed to redesign its aging desktop application with an outdated and unreliable user interface. The legacy system required significant maintenance effort and lacked cross-platform flexibility. Eastgate engineered a modern, modular desktop application that replaced the legacy interface while maintaining 100% backward compatibility and improving overall system reliability and user experience.

Challenge

• Legacy desktop application with outdated and unreliable user interface limiting operational efficiency
• High maintenance overhead due to aging technology stack and monolithic architecture
• Need for cross-platform capability while maintaining backward compatibility with existing workflows
• Performance bottlenecks in data rendering and system responsiveness

Solution

• Modular component architecture enabling maintainability and future scalability
• Modern desktop framework replacing legacy UI with responsive, intuitive interface
• Cross-platform compatibility ensuring deployment flexibility without reimplementation
• Performance optimizations improving data rendering and system responsiveness
• Phased migration strategy maintaining parallel operation during transition period

Architecture

Outcome

• Achieved 30-40% improvement in UI usability and user experience metrics
• Reduced rendering latency by 25-35% improving overall system performance
• Maintained 100% backward compatibility preserving all existing workflows and integrations
• Decreased maintenance burden through modern, maintainable codebase

Tech Stack

• Backend: C#, .NET
• Frontend: WPF, Modern Desktop Framework
• Data: SQL Server
• Protocols: gRPC
