    PEDESTRIAN CONTROL IN LINK MODE  
  PED 1 CONTROL  
    * P1 cannot introduce in AØ  
  * P1 can introduce at any time in BØ provided SG1 is in  
  extension (i.e. Minimum green has expired) and SG1  
 
  gaps or wastes.  
  * P1 can introduce at the start of CØ provided SG1 is in   
    extension (SG1 closes down at the start of BØ yellow).  
  * Any ped demand placed during BØ intergreen or during  
  CØ will not be serviced until the next cycle  
 
    PED 2 CONTROL  
    The introduction of P2 is governed by delay timers  
 
  T1 and T2.  
  * T1 starts timing at beginning of BØ min. green  
  * T2 starts timing at beginning of BØ yellow.  
  * P2 can introduce at any time during the period from   
    when T1 expires until T2 expires, provided SG2 is in  
    extension and SG2 gaps or wastes.  
  * P2 can introduce when T2 expires provided SG2 is in   
  extension (SG2 closes down at the instant T2 expires).

  PEDESTRIAN CONTROL IN    NOTES:  
  V.A.  AND FLEXI ISOLATED MODES   1. Signal groups are independent of phasing.  
  Controller only runs AØ. P1 can introduce in AØ if SG1   2. All phases have a permanent demand in  
  is in extension (i.e. Minimum green has expired) and SG1       Masterlink and Flexilink  
  gaps or wastes. P2 can introduce in AØ if SG2 is in   3. The values of timers T1 and T2 are normally  
  extension and SG2 gaps or wastes.        set at twice the travel time to the reference  
           intersection.
