Intelight MAXTIME is a Linux-based local control software that goes beyond your standard signal timing tools, offering advanced tools and functionality for smart mobility and the future of connected and autonomous vehicles (CAV).

Execute standard signal timing with ease and master advanced functions without complex logic strings or modified controller operations using the system’s intuitive user interface and menu structure.


  • Remote Device Management: Centrally schedule software updates for all intersections without a TMS.
  • Open Standards: Publicly available MIBs promote interoperability with third parties and smart city applications.
  • Modern Web: Monitor and configure timings wirelessly from a laptop, tablet, or smartphone through modern web app
  • User-Friendly Dashboard: Custom your user experience to see just the information pertinent to you for each intersection
  • User Management: Limit read/write permissions of individual controller programming and status menus to a set of users
  • Real-Time Analytics: View graphical signal performance analytic tools such as a split monitor, a cycle length plot, phase termination diagrams, coordination diagrams, etc., directly from the local signal controller. Run queries against signal performance metric events to dig into detailed operational questions.
  • On-Board Replay: Replay recent operation to troubleshoot a failure instantly. Replay includes ring timers, phase and overlap states, detector calls, channel status, etc. Replay can be rewound, fast forwarded, or played back slower or faster than real-time
  • Change Tracking: Track all programming changes entered, including the date-time-stamp, the user name, the previous value, the changed value and a user comment to indicate the reason for the change.
  • CV Ready: Support for predictive Time to Next and Time to Red NTCIP objects for all phases and ped movements in free and coordinated operation,  with confidence intervals, that provides direct integration with INTELIGHT’s MAXTIME cv firmware or other CV applications.
