PHAL stands for stage length control mode. It is designed for controlling stand-alone intersections.

  • Flexible cycle length
  • Parameter-dependent detector functions
  • User-definable extension and modification conditions
  • Definition of special extension points
  • Easy-to-define APS (accessible pedestrian signals) and pedestrian flashers.
  • Control of individual signal groups
  • Public transport features

The following features are available in coordinated stage length control mode, in addition to the functionality already provided in PHAL mode.

  • Automatic monitoring of extension times
  • Up to four coordination intervention points
  • Option to borrow extension time from the subsequent cycle
  • User-defined conditions for terminating forced extensions
  • Optimized extension time distribution for synchronization after switching plans

In SYLVIA+ you can switch plans without compromising traffic flow quality in coordinated controls:

  • Definition of plan-switching points and extension points in pretimed control mode
  • Automatic synchronization by prolonging or shortening extensions
  • Automatic distribution of additional extension time across the entire cycle

The following options are available for expanding the functionality already included in SYLVIA+:

  • Custom definition of additional functions
  • Full access to proven LISA+ functions
  • Definition of pre-logics, post-logics and initialization logics

Control method for coordinated and traffic-actuated controls

Short description

SYLVIA+ is a proven control method for planning traffic-actuated controls and has been used for many years. It is available as an add-on module for the traffic-planning software, LISA+.

APPLICATIONS
  • Standardized control method for all traffic signal controls, ranging from simple to complex
  • Includes public transport priority management
  • No familiarity with logic flow required
  • Extensive integration with LISA+
Benefits

SYLVIA+ is a control method based on signal timing plans. It combines the advantages of a standardized, parameter-based method with the flexibility of the customizable logics created in LISA+. Its particular strength is the implementation of traffic-actuated, coordinated controls.

TARGET GROUPS

Traffic engineering firms, municipal planning departments, controller manufacturers, and colleges and universities
