Hour : Minute Action 10 (time to implement: action to implement)

There must be a minimum of 10 actions per day plan.

There must be a minimum of 15-day plans.

Each action in a day plan must consist of a group of the following objects:

• Pattern, consisting of:

• Cycle length

• Offset

• Split

• MUTCD flash (on-oft)

• Free operation

• Sequence

• Special functions 1-8 ( on-oft)

• Auxiliary functions 1-3 ( on-off)

• Mode of operation ( a means of changing operating modes by time of day)

• Max II

• Gap / extension II

• Phase omits

Any or all of these may be selected within a single action.

Transfer into and out of FLASH must be in accordance with the Texas MUTCD. It must be possible to program each phase and overlap to flash either yellow or red via the front panel of the controller unit. This must be accomplished by flashing the load switch driver outputs simultaneously.

An entry must consist of time period implemented: day plan, months, dates of the month, and days of the week.

A minimum of255 entries must be programmable.

There must be a copy feature that allows the transfer of entries between day plans.

Other programming schemes that meet the functional intent are acceptable but require approval in writing by the TRF Signal Operations Engineer.

D. TBC. The internal reference sync pulse, from which the local offset is calculated, must resynchronize at midnight, or the resynchronization must be user programmable with a default to midnight. A pulse must be generated whenever the time-of-day clock shows a time that is an exact multiple of the current cycle length after this resynchronization. In case of a power failure, re-sync must be calculated from the programmed re-sync time.

The power failure recovery routine must accommodate the case of a power failure at midnight.

E. Diamond Operntion.

1. Program Requirements. Assign phase numbers to traffic movements as shown on the diamond intersection layout in the following figure. Overlap A (OLA) is defined as phases 1 +2. Overlap B (OL B) is defined as phases 5+6.

5. Three-Phase Operation. The controller unit must be keyboard selectable for three phase diamond operation.

The controller unit must perform the sequences for three-phase diamond operation defined in Figure 10 and in Table 4.

The normal sequence of operation must be 4 + 8 � 2 + 6 � 1 + 5 .

F. Coordination-Control lfierarchy. When the system switch is in the SYSTEM position, the controller unit must be under the control of the master controller or TBC.

In the absence of any on line closed-loop-system control by a master controller, the internal TBC must control the coordinated, free, and flash operation of the intersection when the system switch is in the SYSTEM position.

When a master controller brings the intersection on line, its control must supersede that of the internal time-base coordination.

When the system switch is in the FREE position, the controller unit must operate in a non coordinated (free) mode.

G. Preemption (PE). The internal preemptor supplied must be easily programmable from the front panel for either railroad- or emergency-vehicle PE sequences.

Phases must be selectable such that a limited signal sequence may be operational during PE. It must be possible to add phases that are not in the intersection sequence to this special limited sequence without adding external logic.

The intervals shown in Table 5 must be provided as a minimum. Terminology may vary, but the meaning must be clear. Additional unspecified intervals that may lead to confusion must be programmable to zero. If abbreviations are used on the display, they must be defined on the front panel. While in PE, the display must clearly identify the intervals being timed as PE intervals. Yell ow and red clearances from the phase timings may be used in place of the clearance intervals shown.

PE Timing Interval Definitions

Interval

Description

0 PE Delay This time must start immediately when the PE command is received. It must not affect the normal operation of the controller unit until the delay time out occurs. This interval may be used for emergency-vehicle (fire-lane) PE delay. If zero time is set, the interval must be omitted.

1. PE Minimum The PE sequence must not terminate until the PE input signal is removed and the Minimum Duration Duration time has expired.

2. PE Minimum Green Any vehicle signal that is green at the time this interval becomes active must not terminate unless it has been displayed for at least the time programmed in this interval. If zero time is set, the interval must be omitted.

3. PE Minimum Walk PE Minimum Walk Time (in seconds). A PE-initiated transition must not cause the termination of a Walk before its display for this period.

4. PE Ped Clearance At the time of PE call, walk-indications must immediately change to Pedestrian Clearance interval.

The Pedestrian Clearance interval must not terminate unless it has been displayed for at least the time programmed in this interval. If zero time is set, the interval must be omitted.

5. PE Track Green Signals programmed as track (or fire-lane) signals must remain green or be changed to green. All other signals must be red. This interval must be optionally programmable to zero during emergency-vehicle PE.

6. PE Dwell Green Minimum Dwell Time (entered in seconds). This parameter controls the minimum timing for the dwell movement. The phases allowed during the dwell interval must be selectable to include all phases that do not cross the track. The dwell interval must not terminate before the completion of PE-duration time and PE-dwell time, and until the call is no longer present. Each signal must be keyboard-programmable for red, red flash, yellow flash, or green. As an alternative, a limited cycle must be programmable for use with railroad PEs.

7. PE Exit Ped Clear PE Exit Pedestrian Clear Time (in seconds). This parameter controls the pedestrian clear timing for a walk signal transition to the exit phase or phases.

8. PE Exit Yellow This interval must provide a solid yellow clearance for indications that were green or flashing yellow. Red and flashing red displays must display solid red.

9. PE Exit Red This interval must be an all-red clearance in preparation for return to the normal cycle. Return phases Clearance must be programmable from the keyboard.

10. PE Max Call This interval is the amount of time that a PE call may remain active and be considered valid. When the PE call has been active for this amount of time, the controller must return to normal operation.

The PE call must be considered invalid until the call is no longer active.

The phases to be serviced following the PE sequence must be front-panel-keyboard programmable.

PE sequences must be selectable using external inputs. PE priority must be assigned with # 1 being the highest. If a higher-priority PE input is received during a PE sequence, the controller unit must immediately transition to the new sequence subject to the constraints of PE Minimum Green and PE Minimum Walk. The transition must take place in a safe manner from any point in the sequence and must meet all Texas MUTCD requirements.

Provisions must be made to clear two conflicting track phases from a single PE input.

This may be provided by two-track clearance phases for a single PE or by combining two PEs.

PE 1 must be reserved for a priority railroad PE. If more than two PEs are provided, it must be possible to delete the priority override for all but the railroad PE. If a non-priority

PE is activated during another PE cycle, the one in progress must continue through its entire cycle. If the second PE input is still active when the first one is completed, the controller unit must immediately go to all-red flash or initiate the non-priority PE. When all PE inputs are removed, the controller unit must proceed through the normal sequence to Return Red Clearance (interval 9).

Once the controller unit has entered the first timed interval following PE Delay (interval 1 ), the sequence must continue to the end, even if the PE call is dropped. If the call returns, the Minimum Preempt Duration (interval 1) the controller unit should reinitiate track green and complete the PE sequence.

The controller unit must be programmable to be in flash or in limited sequence during interval 6. If flash is specified, the phases must flash yellow or red as programmed from the front panel. Flash must be implemented by simultaneously flashing the appropriate
