System Architecture

Traffic Light Control & Traffic Signal Priority

  • city of Leipzig
  • transport information system of Leipzig
  • FIFO-Priorization for public transport is not physically sensible and feasible in every traffic situation.
  • FIFO-Priorization can have a negative effect on traffic quality and public transport operating quality.

Traffic Light Control & Traffic Signal Priority>>> Quality optimized traffic light control

  • Prioritization for certain public transport vehicles
  • Withhold premature vehicles
  • Concerning the planned order of public transport vehicles at decisive nodes
  • Reliable connections in public transport
  • Considering traffic situation of all transport users
  • Improving punctuality
  • Reduction in the spread of travel time
  • Improvement in transport quality for all transport users
  • Saving of traction energy
  • Ensuring the efficiency
  • Avoiding interruptions of green waves by public transport
  • Enviromentally friendly mobility on main traffic axes
