INSTRUCTIONS TO RESPONDENTS

USE OF NATIONAL INSTITUTE OF GOVERNMENTAL PURCHASING CODE

The Texas Department of Transportation (TxDOT) uses the National Institute of Governmental Purchasing, Inc., (NIGP) code to standardize purchases by conforming to the class, item, and group structure of the code. The NIGP code is used to select vendors for our master vendor file from the Texas Comptroller of Public Accounts (CPA) Centralized Master Bidders List (CMBL).

New suppliers and other vendors wishing to furnish materials, equipment, supplies and services to TxDOT should apply to be on the CMBL to receive bidding opportunities.

Existing TxDOT vendors need only be concerned that the information listed on the CMBL file is correct, and that the applicable NIGP class and item are selected for those you can provide.

CMBL information is available online at: https://comptroller.texas.gov/purchasing/vendor/cmbl/ or by phoning 1-512-463-3459.

Early Payment Program - TxDOT is offering an important program to all respondents that provide prioritized invoice processing and payments (prior to the 30th day after receipt of a correct invoice). The program provides enrolled vendors enhanced benefits from improved invoice processing to priority handling to cash advancement and technology efficiencies.

Respondents offering a cash discount in exchange for TxDOT’s priority invoice processing and early payment agreement should complete and return the attached form entitled “Priority Invoice and Early Payment Program” with the response.

MPL. If material is listed on the MPL, no additional submittals are required for that product.

Date of acceptance will be date that TRF approves the controller cabinet assembly.

The traffic signal controllers and cabinets must be identical to the approved pre-qualification sample. Submit any deviations from the approved sample for evaluation and approval before any shipment is accepted for payment.

Deviations from the approved sample after shipment of any parts of the order will be cause for rejection and nonpayment of the remainder of the order. Excessive delays or noncompliance by the vendor at any point in the approval process may be cause for cancellation and nonpayment.

2. Failure. Producers not qualified under this Specification may not furnish materials for

Department projects and must show evidence of correction of all deficiencies before reconsideration for qualification.

If any of the assemblies fail any of the tests, the supplier will be permitted to make one complete repair of the order on a timely basis, as determined by the Department. The supplier must reimburse the Department for any retesting required during acceptance.

The Department will base the cost for each retest, estimated at $1,500 per test, on time and charges.

TRAFFIC SAFETY DIVISION 4 – 40

Minor discrepancies noted in sampling and testing of this item must be corrected within

30 days of written notice of the discrepancies or as stated in the notice. Major discrepancies that in the opinion of the Department will substantially delay receipt and acceptance of the item will be cause for cancellation of the purchase order.

TRAFFIC SAFETY DIVISION 8 – 40

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

A minimum of 255 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 Operation.

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

There must be six additional user-programmable overlaps. All additional overlaps must be programmable through the keyboard and must function as specified by TS 2.

The controller unit must be programmable for four-phase and three-phase diamond operation as well as for two independent, four-phase rings (separate intersection operation) as shown in the following figure.

The following modes must be available for each phase and for the intervals identified as special intervals in three-phase and four-phase operation:

• Maximum Recall

• Minimum Recall

• Pedestrian Recall

• Detector Locking and Non-Locking Memory

• Phase Omit

The controller unit must be designed to provide pedestrian phasing with phases two, four, six, and eight.

All timing entries and displays must be available for phases three and seven.

The operation of the controller unit as a four-phase, three-phase, or separate-intersection-operation diamond must be keyboard selectable. This must be overridden while under closed-loop system control or by TBC control.

2. Four-Phase Operation. The controller unit must perform the sequences for four-phase and 6-phase diamond operation defined in Figures 3–8.

The normal four-phase operation sequence must be: 18164525 →→→ . The six-phase operation sequence must be: 181716453525 →→→→→ .

The point at which operation may be switched from four-phase to three-phase operation must be at the clearance interval 2516B or 2518B to the three-phase clearance interval 15.

3. Concurrent Timing Requirements. Refer to Figures 3–6 for the following descriptions:

Intervals 4516B and 4516C must time concurrently with interval 16; however, interval

16 may not terminate green until interval 4516C has timed out.

Intervals 3516B and 3516C must time concurrently with interval 16; however, interval

16 may not terminate green until interval 3516C has timed out.

TRAFFIC SAFETY DIVISION 10 – 40

Intervals 1825B and 1825C must time concurrently with interval 25; however, interval 25 may not terminate green until interval 1825C has timed out.

Intervals 1725B and 1725C must time concurrently with interval 25; however, interval 25 may not terminate green until interval 1725C has timed out.

All left-to-right internal clearance times (intervals 4518B, 4517B, 3518B, 3517B, 2518B, 2517B, and 2516B) must use the same timing settings for minimum green, extension, maximum (max) green, yellow clearance, and red clearance.

All right-to-left internal clearance times (intervals 1845B, 1835B, 1745B, 1735B, 1645B, 1635B, and 1625B) must use the same timing settings for minimum green, extension, max green, yellow clearance, and red clearance.

Separate timing settings for minimum green, extension, max green, yellow clearance, and red clearance must be provided for each of the four external clearance intervals

(1825B, 1725B, 4516B, and 3516B).

Detector Operation Requirements

Detector Four- and Three-Phase Requirements

1 In 4-phase operation:

▪ Must call phase 6 if Overlap A is not green and phase 7 is not called.

▪ Must call phase 6 if Overlap A is not green and phase 8 is not called.

▪ Extend intervals 2516B, 2517B, 2518B, 4517B, 4518B, 3517B, and 3518B.

In 3-phase operation:

▪ Must call and extend phase 1 (left turn).

5 In 4-phase operation:

▪ Must call phase 2 if Overlap B is not green and phase 4 is not called.

▪ Extend Intervals 1625B, 1635B, 1645B, 1735B, 1745B, 1835B, and 1845B.

In 3-phase operation:

▪ Must call and extend phase 5 (left turn).

2, 3, 4, 6, 7, and 8

These setback detectors (or detector sets) belong to the parent phases with the same number

(e.g., detector 2 belongs to phase 2) as shown in Figure 9. These detectors must have a 2-sec.

delay set during red conditions of their parent phase. The detectors are used to extend the parent phase during green.

11, 12, 15, 16, 17, and

These detectors are stop bar detectors and are used to call the associated parent phases shown in

Figure 9. The parent phase green plus a call for that phase plus a 0.2-sec. gap on the detector must disable the detector until the end of green.

9 and 10 In 4-phase operation:

▪ Must extend phase 2 if phase 3 is called

▪ Must extend phase 2 if phase 4 is called

▪ Must call phase 6 if Overlap A is not green and phase 7 is not called

▪ Must call phase 6 if Overlap A is not green and phase 8 is not called

▪ Extend intervals 2516B, 2517B, 2518B, 4517B, 4518B, 3517B, and 3518B

In 3 phase operation:

▪ Must function as a phase-1 calling detector during phase 3 or 4 and as a phase-1 extending detector when a phase 3 or 4 call exists

13 and 14 In 4 phase operation:

▪ Must extend phase 6 if phase 7 is called

▪ Must extend phase 6 if phase 8 is called

▪ Must call phase 2 if Overlap B is not green and phase 3 is not called

▪ Must call phase 2 if Overlap B is not green and phase 4 is not called

▪ Extend Intervals 1625B, 1635B, 1645B, 1735B, 1745B, 1835B, and 1845B

In 3 phase operation:

▪ Must function as a phase-5 calling detector during phase 7 or 8 and as a phase-5 extending detector when a phase 7 or 8 call exists

TRAFFIC SAFETY DIVISION 15 – 40

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 516284 +→+→+ .

The point at which operation may be switched from three-phase to four-phase operation must be through the transition phase sequence to four-phase interval 25 as indicated in

Figure 10.

The controller must be programmable for simultaneous gap operation for phases 4 and

8 in three-phase operation to allow a phase to extend out of a green rest state. When the phase or phases to be serviced next conflict with both phases being serviced, both concurrent phases must reach a green rest state together before they terminate.

Termination of the max timer or application of a force-off must override this feature.

The phases must not be allowed to advance to a green interval beyond the rest state that might override or defeat the simultaneous gap operation.

F. Coordination-Control Hierarchy. 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. Yellow and red clearances from the phase timings may be used in place of the clearance intervals shown.

TRAFFIC SAFETY DIVISION 18 – 40

Table 5

PE Timing Interval Definitions

Interval1 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

Duration

The PE sequence must not terminate until the PE input signal is removed and the Minimum 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

Clearance

This interval must be an all-red clearance in preparation for return to the normal cycle. Return phases 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

TRAFFIC SAFETY DIVISION 20 – 40

load-switch driver outputs. If limited sequence is selected, all phases must be programmable even if not normally used in the intersection sequence.

In the event of a power interrupt as defined by TS 2, if the PE command is present when power is restored, the controller unit must power up in cabinet flash operation and remain there until the PE command is removed.

Overlap phases must begin and terminate with the parent phases as described in TS 2. If the PE call occurs during yellow or red displays between parent phases, the overlap phase must display a minimum of 3 sec. of yellow and a minimum of 1 sec. of red clearance.

“Don't Walk” must be displayed throughout the PE sequence unless a limited cycle is run.

During a limited cycle (interval 6), the pedestrian heads may be programmed to be dark.

PE routines must have priority over all controller functions.

The controller must be programmable to allow multiple track clearance phases either within a single PE sequence or by…
