The lane level is the basic level of the system. It´s made up by the lane controllers and all the necessary devices for toll collection and control and signalling of passage of vehicles. These devices also categorize them generating relevant information and storing and transmitting it to the station level.
A toll lane is a functional unit that reports to the station level and is independent of the rest of the lanes. the toll fee -paid according to the passing vehicle characteristics- is performed through it .

Lane types

The toll system has 4 lane configurations :
Unidirectional manual lane
Bidirectional manual lane (reversible)
Atomatic/ manual lane
Manual/ avi lane
In a physical lane there can be:
Only one lane. (unidirectional lane)
Two lanes (one for each direction)
There is only one lane controller for all lane types.
for avi lanes, the lane controller includes a second inductive loop detector (for entrance loop) an antenna interface card and a 48vdc power supply.

Special Keys (red)

Functions of each key:
– Category keys
1 to 7 categories
They indicate the vehicle category: when one of them is selected the system calculates the amount to be paid
– Operative keys

It´S used to open or close a lane. The lane closing through this means leaves the shift
in stand-by.

It´s used for the shift closing and generates information for a cash closing

It allows the operator to communicate with the station qualifying the selection of a list of
predetermined messages .
La lista de mensajes se configura desde el software de Gestión y es la misma para todas las

It desactivates the alarm and is used in emergency cases or for vehicles that have not made the corresponding payment.

It allows to modify the marquee traffic light state.
– Special Keys

It allows to simulate the exit loop

It recharges a pre-paid tag

In certain cases, it interrupts the function that is being executed
– Validation Keys

It assumes this payment mode.
Free of charge. It allows the passage of a free of charge user who does not possess a card, qualifying is details through the operator

It admits the register of details of users who do not pay but promise to do so by means
of a document drawn by the operator

It is a differential tariff given to users who live near the toll plaza
Every neighbor has a magnetic strip that is driven through the automatic reader or
through the lane operator keyboard. If the neighbor doesn´t have a magnetic strip, he
will have to go through a manual lane and give his details to the operator.
The neighbor´s details are validated by the server. In the case of being off-line, they
will be considered correct. Magnetic strip reader
The magnetic strip reader is connected with the rest of the keyboard body. (ISO II magnetic band)

3.2.3 Fiscal printer
The fiscal printer is the unit in charge of issuing a receipt (a ticket ) in accordance to the DGI 4104/96 General Resolution. For this, the equipment to be used is appropriately accredited hrough the General Resolution of the Federal Administration of Public Income of the Argentine Republic.

Ticket format

3.2.4 Alarm button
This is placed nder the booth operator ‘s desk and consists of a push – button switch (single pulser) In case of an emergency, the booth operator presses the button with his knee producing a message on the screen of the Toll plaza Supervisor.

3.3 Blister
It is a device that is placed on the lateral of the collecting booth and contains all the elements that allow the collecting management with magnetic strips and the interaction with the user.

The blister includes:
1 magnetic strip reader
1 LCD display

3.3.1 Motorized Magnetic card reader (ISO II)
The motorized magnetic strip reader can read and write on magnetic strips using the ISO II track

3.3.2 Attention Display
LCD user’s display , of alphanumeric information of two lines and 20 characters. This display is placed in front of the blister so that it can be seen by the vehicle driver. All the interface with the user will be done through it. The messages displayed will be of help of the “Category 2″, type such as, insert Strip”, “insufficient balance”, “Have a good trip”, etc.

3.4 Antenna
Each AVI Lane is equipped with an antenna (installed on the marquee) and an interface plate (integrated to the Lane Controller). The Tags’ reading / recording antenna allows the reading and updating of the members associated to the AVI collecting system.

3.5 Lane Devices

3.5.1 Entrance Automatic Barrier (optional)
The Entrance Automatic Barrier is placed on the isle before the Collector Booth and is driven to indicate that the lane is open or closed. It coincides with the green or red light of the Marquee Traffic light. It covers the lane width so that it doesn´t allow the passage through it when it is closed. The room left is such that it won’t allow the motorcycles out either.

3.5.2 Exit Automatic Barrier
The Exit Automatic Barrier is placed on the collector booth isle and is driven at the moment the transaction is validated. It covers the lane width so that it doesn´t allow the passage through it when it is closed. The room left is such that it won’t allow the motorcycles out either. When the vehicle leaves, the magnetic loop detects it and the system produces the barrier closing automatically.

3.5.3 Traffic light
The Traffic light is placed on the collecting booth isle and indicates the vehicle driver the moment when he is bound to continue the journey. Once the transaction is validated, the green light is activated to give way to the red light automatically once the inductive loop detects the exit of the vehicle. The traffic light has a sound alarm incorporated that indicates the supervisors and toll booth operators that a violation is taking place in that lane.

3.5.4 Marquee Traffic light
The Marquee Traffic light is placed at the height of the marquee profile and attached to it by means of the corresponding marquee notice . It tells the driver if the lane is qualified for the collecting task. The lane opening is signaled through a green light flash and the lane closing through a red one, both working together with the entrance barrier and commanded by the lane controller.

3.5.5 Exterior Display
It is installed in AVI Lanes. It is a panel of at least 2 rows and 12 characters per row and informs the user about his transaction. It is placed on the traffic light post. The messages to be shown are of the type: “Category
2”, “Puentes del litoral”, “Have a good Trip”, “Thank you very much”, etc.

3.5.6 Video System
Each lane is equipped with a camera situated on the traffic light post. It allows to take the photograph of vehicles in specific situations.

3.5.7 Marquee Variable Notice
Every mixed lane (Manual / AVI) is equipped with a marquee variable notice .

Manual/AVI lane
Manual and AVI

3.5.8 System of Categories Automatic Detection (DAC)
The DAC system is used to obtain a series of parameters to estimate the category of the vehicle that has just paid. The detection mode is of post-categorization (POSTDAC), which means that the system will categorize the vehicle after the toll booth operator has tabulated the category and qualified the way through. In this way, it will be possible to check if the category tabulated by the booth operator is correct. The same procedure will be used in those cases in which the vehicle goes through an AVI mode open lane. It will be categorized when leaving the lane and these details will be incorporated in the transaction. The system possesses axle- detectors and double tyres (group of treadles)

3.5.9 Vehicle separador
The vehicle separator is the unit in charge of detecting the discontinuity produced by the passing of two consecutive vehicles going at a high speed.
It will be placed in all Manual/AVI lanes. Its function consists of allowing a reliable passing logic avoiding ghostly violations or inopportune AVI management.

3.5.10 Height detector
El mismo se encuentra incorporado al separador de vehículos, antes mencionado y forma parte del sistema de DAC. The height detector is the unit able to emit an electric signal at the moment a passing vehicle has a height superior to 2,20 meters.

3.5.11 Inductive loops
The magnetic inductive loops (inductive coils) are made up by wire loops with copper inductive coils: they are placed on the ground and connected to the metallic mass detector, essential to detect the presence of vehicles.
When a vehicle stands on it a variation in the inductance value is produced; once this happens, it brings about the driving of one of its exits.

The toll system has three types of inductive loops
Entrance Inductive loops (for AVI lanes)
Presence-detection Loops
Exit loops

Lane level software

The software runs under Windows NT and works with menus that present interactive screens with friendly graphic interfaces. The software as well as the hardware need Y2K Compatibility for an integral functioning.

Functional description

The lane controller is in charge of:
Managing the passage logia
Commanding the interface with the operator
Managing the control and communication with all the devices
Managing the communication with the Station Server
Registering all the anomalies, discrepancies, flaws, violations, transits and shifts that take place in the lane.
Storing the tariffs and category charts according to the number of axles
Storing the tariffs and category charts according to the number of axles
– Configuring the hardware elements the lane has.
– Allowing the connection of remote users to diagnose the lane from other locations.

5.1 Lanes State
The lane controller can be :
Switched off
Closed Lane
Open Lane:

Manual and AVI

The change of state is controlled using the “Operator´s Identification Card” (contactless card)

5.1.1 State – Closed lane
The closed state appears when the lane controller is on, its application is working but the shift is not open.
In this state, the lane is waiting for either local commands or commands from the server. At the same time, it will register all the incidents that can be detected.
All the vehicles that go through the lane in this state will be entered as closed lane violation and stored in the system with time, date, lane number and category. These messages will be associated to the station shift in the system, since in the closed lane state there will not be any open shift where to register these messages.
In this state, the lane is apt to receive messages; so, the screen zone for messages will display the last messages with their corresponding time and date.

It will take place with the ignition of the equipment. It includes all the ignition processes until the indicator of “Closed lane” appears on the screen zone intended for that. During this transaction the lane does not detect any type of event (command or signal).
During this transaction, the lane controller verifies the system integrity and the functioning possibilities. In case of being on-line it will show the users’ charts, the tariffs, the senders(issuers) and any other chart managed on line.

It will take place by means of an event of closing lane or shift, either locally or remotely. To be able to close the lane, the must not be any vehicle there. On the contrary, when intending to close the lane, the corresponding information will appear on the screen.
The closing will be performed in two different ways:
Local: From the toll booth
Remote: From the station supervisor terminal
It can be closed:
Shift Closing: The next time the operator opens the lane a new shift will be generated
Lane Closing: The next time the operator opens the lane a different sub-shift, within the same shift, will be generated.

5.1.2 State – Open lane

The lane opening ways are:
Automatic: When they work without any human intervention, using a motorized strip reader Manual: When the booth operator is the one that controls the lane.
AVI: When they work without any human intervention, accepting AVI as a payment mode.
At the same time, the shift can be opened in two different modes:
Toll booth operator
The modalities defined in this project in which each lane type can operate are:

Lane Opening
It will be performed through local login or opening telecontrol.
The opening can be:
– Local: When the opening is performed from the Toll booth. In this case there are two opening options:
– Strip : The booth operator drives his card and inserts his password
– Keyboard: The booth operator presses the login button and then types his dossier (or record) number and password.
– Remote : When the opening is performed by the station chieffrom the control spot. In this operation he will have to introduce the number of the booth operator´s dossier (or record) which will remainregistered.
The local opening can be performed under this situation:
ON-LINE: There is a real time connection with the station server
OFF-LINE: There isn´t any connection at that moment.
In case the lane is off-line, the system will locally validate the dossier (or record) number and the password, with the last users’ chart in force.
Once the controller has received the order to open (whatever the origin), the opening process is similar for all the cases.
In case of being on-line:
It brings the users, versions and issuers chart
Based on the versions chart, it asks the server the versions charts that it doesn’t have.
It asks the Server for a shift number
In case of being off-line:
It generates a shift locally
It uses its internal counter of ticket number.
In both cases:

– It verifies its correct operation and in case of any flaw in a certain device it will register the incident with the mistake and will remain in closed lane state.
– It goes on to the corresponding state whether the dossier (or record) number belongs to a booth operator or to a maintenance worker, and according to the opening mode registered.
– The fiscal printer automatically assigns the Ticket number.

5.1.3 Shift number allocation
The shift number will be assigned by the station during the lane opening. If for that booth operator the station found a shift open, no other new shift will be opened but a new sub-shift for that shift. If, on the contrary, there are no open shifts, the station will assign a new shift number. All these proceedings will be performed through the messaging between the lane and the station (opening request)

In case of there not being any communication with the station, the lane assigns a shift according to its counters and indicates this condition in all the messages generated in off-line mode. The lane does not work with sub-shift assignments for which it will generate new shifts in all cases.

5.2 Maintenance Mode
This type of test is executed from the closed lane state, and allows to test the lane elements from the lane controller. This item is very useful to start the system and when some important maintenance is done to it.
The aim of this type of test is to give the possibility of managing the signal elements from the supervising computer seeing that what enters there reproduces what in fact occurs in the lane. In this way, it will be possible to modify the passage and marquee traffic lights, the display messages and watch- apart from all thisthe state of the DAC detectors. Besides, it will be possible to print test tickets, read magnetic strips and visualize their content and perform barrier openings and closings.
It is possible to check the lane controller operation and see that its memory is free of flaws. (auto test) This modality can be only entered with duly authorized strips.
The entrance / exit to this maintenance modality will be stored in the system within the events and auditory register, keeping the number of strip entered and the people involved in it, date/time and lane number.
With this modality it will be posible to:

Modify ports configuration
Modify the number of report copies
Modify E/S device addresses
Modify device libraries
Modify the station and lane number
Modify hardware general configurations
The specifications of the test operation are:
It will not cahnge the marquee traffic light to green
The “Open Maintenance” will be indicated in the display
It will send Registers of 0 value
It will print tickets of 0 value
The date/time will be able to be changed
It will be possible to switch off the controller
AVI Transactions with test tags.

5.4 Communication with the station
On-line: it is the normal operating state; in permanent communication
Off-line: In case of losing connection, the lane software works independently. It performs validations against the received parameters in the shift opening.
As it is not possible to perform liquidations in this operation mode for lack of information, all the data is transferred once the connection is recovered. Only at that moment can the balance be closed.
In this mode the lane files can be updated only from the Station, using a diskette with files of Tariffs, White lists, Black lists, Operators, etc.
It is not possible to send diskette information from the lane to update the station data base. This operation will be performed automatically when the communication between both levels is restored.
The Station Messenger Server automatically starts when the PC is switched on. It internally keeps the data of the lane development updated.
When detecting a lane opening the following operations are performed:
It validates the user’s details (manually or through magnetic strip ) against the users chart.
It assigns a shift number, checking that the last assigned shift to that user has been closed. On the contrary, it gives way to the shift in force.
It transfers the updated data referred to tariffs, users and quotations to the lane PC .
At a vehicle´s arrival, it performs the following operations:
– It receives the vehicle ‘s information generated by the lane.
– It validates the data sent by the lane, checking if:
– There exists the Bin Code Combination (according to ISO norms) / Service Code
(it indicates the type of user, kind of “free of payment”, etc)
– If a neighbor is using the system, it means that he exists and is not in the black

If a “free of payment user” is using it, it means that he exists and is not in the
black list.
It sends the reply to the lane.
It records date, time, shift, lane, anomalies and incidents in the base.

5.5 Special functions
5.5.1 Special functions of the Booth operator keyboard

It allows to simulate the Presence, Entrance and Exit inductive loop
It gives way to the necessary functions at moments when there are flaws in the vehicle inductive detectors
Ex: – Force the exit barrier action in case the vehicle exit is not detected
– Initiate the collecting function if the presence of a vehicle is not detected
at the entrance loop

It is used when a pre-paid TAG user manages the recharge of it.
The booth operator will have to select this key and enter the amount he wants to load as credit in the Tag.
In certain cases, it interrupts the function that is being executed.
The passage logic operations can be cancelled until the moment of pressing the collecting key
Once the collecting key is pressed, the operation cannot be cancelled.
The “cancel” operation can be performed in the Manual Type Lanes.

The booth operator has a series of messages- defined by the user – that can use to send to the station by
means of a selection from a list.

5.5.2 Image capture
A CTV camera will be capturing everything that takes place in the lane. For each activated device, there will be an image capture that will be provisionally kept until the transit is completed.
Once the transit is completed, and if there had been any anomaly, the image captured will be kept. This image will go together with the corresponding transit data and will be of great use in the validation process.
