15 APPENDIX III - Mains supervision

15.1 Mains voltage [V]

The page ”Mains [V]” gives some additional mains voltage supervision options. It is based on two sections: basic and advanced, designated for those who wants to achieve a very precise and strict level of supervising mains voltage.

Figure 265: Mains

15.2 Minimum mains voltage 0-255 V

The controller switches instantly to the failure mode with dark lamps, when the mains voltage drops below this value and the duration of the voltage dip is equal or longer than specied in F993N4. The controller remains in this mode until the mains voltage again has been a least 5 seconds. A programmed value of zero disables this function.

Figure 266: Minimum mains voltage

15.3 Maximum mains voltage 0-300 V

The controller switch instantly to the failure mode with dark lamps when the mains voltage is above this value. The fault will be cleared again when the mains voltage has been inside the interval between the minimum and maximum for more than 10 seconds. A value of zero will disable the checking of maximum voltage.

Figure 267: Maximum mains voltage

15.4 Mains supply frequency 50-60

The mains frequency can be set to 50 or 60 Hz.

Figure 268: Mains supply frequency

15.5 Mains voltage dip duration 0-40

The value is given in 20 ms resolution. A value of zero will internally be considered as 60 ms.

Figure 269: Mains voltage dip duration

15.6 Auxiliary mains voltage 0-255

An extra mains voltage value can be defined to achieve a state in which a fall in mains voltage below this value will force the controller into a controlled shut-down mode (see also F999N41). Flashing yellow will be displayed in failure mode if not F993N1 is set to dark failure mode (+2). The value must be above the minimum value defined in parameter F993N2. A value of zero disables this function

Figure 270: Auxiliary mains voltage

15.7 Mains frequency limit (critical) 0-20

The controller will switch to the failure mode when the mains frequency variation is more than the +/- limit. The fault will be cleared again when the frequency has been within the limit for at least 10 seconds. A value of zero will disable this function.

Figure 271: Mains frequency limit

15.8 Mains frequency limit 0-20

The controller will set a fault when the mains frequency variation is more than the +/- limit. The fault will be cleared again when the frequency has been inside the limit for at least 10 seconds. A value of zero will disable this function.

Figure 272: Mains frequency limit

16 APPENDIX IV - Capacity evaluation module

16.1 Introduction

Capacity evaluation module allow you to check your intersection performance under the pre- defined traffic control conditions. Open the Capacity evaluation module and follow 5 steps procedure in order to achieve final results.

Define the number of approaches and departures as you see it on the junction,

Figure 277: Number of approaches/departures

16.2.3 Traffic lanes and movements

Define the directions and the signal group associations. 3,5 m is a default lane width and can be changed.

Figure 278: Number of legs

16.2.4 Approach grade

Define the approach grade for each leg.

Figure 279: Approach grade

16.2.5 Pedestrian crossing

Locate the pedestrian crossings (choose the distance C and the signal group association):

Figure 280: Pedestrian crossing

16.2.6 Turning radius

Turning radius might influence the final results. It is as well important to clarify values as they are on site.

Figure 281: Approach grade

16.3 Step 2 - Traffic flows

Define the traffic flow and HGV ratio according to your traffic studies. It is possible to declare few different periods.

Figure 282: Traffic flows

16.4 Step 3 - Saturation flow

Check the Saturation flow evaluation and modify specific factors if necessary:

Figure 283: Saturation flow

Use Glossary to check the meaning of each factor.

Figure 284: Help

16.5 Step 4 - Results

Results grouped on the Step 4 present the traffic conditions on each lane group.

Figure 285: Lane group results

Use Glossary to check the meaning of each value result.

Figure 286: Help 2

16.6 Step 5 - Results

Results on the step 5 present the overall intersection performance. Values are presented for each leg and for the whole junction both in tabular and graphical way:

Figure 287: Lane group results

17 APPENDIX V - Intersection documentation

You can create a document from you ITC configuration. Select Reports function from the Main

Menu bar and choose your preferable template from the list:

Figure 289: Main menu Report function

Modify and save your own template files which can be found in .Work¿WordTemplates folder:

Figure 290: Main menu Report function


18.1 Intersection layout

The interaction has 6 vehicle groups (G1, G2, G3, G4, G5 and G6) and 3 pedestrian groups (P1, P2, P3).

There are 4 loop detectors (D1, D2, D3, D4) on the main road and 4 video detectors on the side roads (C1, C2, C3, C4). Video detectors connects to the digital input terminal. The pedestrian push buttons (P1, P2, P3) connects to the Aux/Red2.

Figure 291: Intersection layout

The Stage Sequence contains both main and alternative stages (A, B1, B2, C, D and E).

18.2 Step 1 Intersection layout

First switch the graphical mode and type the intersection name, Backplane ID, number of signal groups, plans etc.

See: Quick Start View button section 3.5 page 17

Figure 292: STEP 1

See: STEP 1 - Intersection layout section 4.1 page 18

18.3 Step 2 Signal groups

Click STEP 2 button and decide the signal groups name, type and min group sequence.

Figure 293: STEP 2

See: STEP 2 - Signal groups section 4.3 page 25

18.4 Step 3 Conflicts

Fill in the intergreen time matrix with the values from the traffic design. Values should always consider the local traffic regulations, speed and distances.

Figure 294: STEP 3

See: STEP 3 - Minimum inter green time matrix section 4.4 page 29

18.5 Step 4 Conflicting group numbers

Table from STEP 4 contains conflicting group numbers

Figure 295: STEP 4

See: STEP 4 - Signal group conflicts section 4.4 page 31

18.6 Step 5 Start-up sequence

Choose start-up sequences from the list - different for the vehicle and pedestrian signal groups.

Figure 296: STEP 5

See: STEP 5 - Intersection start-up sequence section 4.6 page 32

18.7 Step 6 General plan programming

Make the signal plans ”isolated type” and decide the star-up and rest stage. To learn more about:

- start-up stage definition see: Start-up stage section 4.7.3 page 34

- rest stage definition see: Rest stage programming section 6.1.1 page 89

Figure 297: STEP 6

See: STEP 6 - General plan programming section 4.7 page 33

18.8 Step 7 Lamp supervision programming

See: STEP 7 - Lamp supervision section 4.8 page 36

18.9 Step 8 Intergreen time matrix

The Intergreen time marix from STEP 8 usually contains both physical and logical conflicts - more about logical conflicts in section 4.9.2 page 41

Figure 298: STEP 8

See: STEP 8 - Physical and fictive inter green time matrix section 4.9 page 40

18.10 Step 9 General plan programming

The plan drawing represents the traffic design. If your traffic design contains only the tabular representation of the green times, you can draw it on your own here in STEP 9. When the drawing plan structure in STEP 9, consider both the green times and stage sequence.

Figure 299: STEP 9

Here you should consider the main stages only. Don’t draw any alternative stages here. How it is decided that the stage B2 is a main stage and the B1 is an alternative one?

Simply, if we made the B1 main stage then groups P8 and P9 would never get green as these groups don’t belong to any other stage but only to B2. That is why the B2 stage is a main stage. And only if the P8 either P9 is not requesting, controller can create the alternative stage B1, with the left turn G4 green two times, in stage B1 and E2.

See: STEP 9 - Traffic plans programming section 4.10 page 43

18.11 Step 11 Stage sequence

The Stage Sequence usually contains programming for main stages only. You don’t have to program the alternative stages here. Alternative stages will be created by the controller auto- matically, following some additional rules programmed in the Detector Logic.

Figure 300: STEP 11

See: STEP 11 - Stage logic programming section 4.12 page 55

18.12 Step 13 Loop detector hardware programming

The software generates the default loop detector hardware programming.

Figure 301: STEP 13

See: STEP 13 - Loop detectors section 5.1 page 66

18.13 Step 14 Detector Logic

The Detector Logic programming links loop and video detectors with vehicle groups:

Figure 302: STEP 14 - loop detectors and digital inputs

The Detector Logic programming links the push button inputs with pedestrian signal groups:

Figure 303: STEP 14 - push buttons

See: STEP 14 - Detector Logics section 5.2 page 68

18.14 Step 10 Sequence Logic programming

Press the ”vehicle actuated” button and change the default fixed time settings to vehicle ac- tuated.

Figure 304: STEP 10

You can also add Sequence Logic in STEP 1, make it fixed time plan and associate with Plan 3. This way first two plans would remains vehicle actuated and the last one fixed time plan (back up plan).
