Traffic management
1. Presentation of the equipment
This assembly consists of 2 subassemblies (the control part and the operative part) and comes with a technical manual and an exercise manual. It is intended for people wishing to learn how to program in the "List / Ladder, Literal and Grafcet" language of a PLC.
1.1 Composition
The operative part: traffic management simulator of a crossroads, consisting of a traffic light to be managed according to day and night, pedestrian calls, priority choices, etc.
The control part: made up of a data processing assembly consisting of:
A PLC (‘TSX07, TSX37, Twido or Zélio according to option) and its extension containing the crossroads traffic light operating program, mounted and cabled on a support equipped with connectors for simple, quick connection with the operative part
The operative part connection cables
A setting and programming terminal in Boolean language for the PLC

Traffic management
1.3 Main functions
The traffic management bench is used to:
Simulate entry to a car park:
Automatically open and close a barrier by detection of vehicle presence
Control the barrier according to the number of places available inside the car park
Manage crossroads traffic according to:
Day and night
Pedestrian calls
The priority given to one lane over another

2. Teaching
2.1 Presentation of teaching
The traffic management bench allows:
Signalling of passageway for pedestrians: from cabled logic to programmed logic
Detection of vehicle presence at the entry to a car park: the Grafcet
Study of lane A: day-time operation: the time-delay
Study of lane A: night-time operation: astable switch
Manual operation of traffic lights: step by step
Management of available spaces: counting
Comprehensive study of crossroads traffic management
It is intended for the following channels:
Professional Secondary Universities Engineering schools
Monitoring and Regulation Electrotechnical Technical Equipment - Energy Various Production
Some exercises that can be carried out using the traffic management bench: they consist of a teacher's document with answers and a trainee document.
Exercise 1: Signalling a passageway for pedestrians lane A
Exercise 2: Detection of vehicle presence at the entry to a car park
Exercise 3: Study of lane A in "day-time" operation (example given on p.7 to 14)
Exercise 4: Study of lanes A and B in "night-time" operation
Exercise 5: Study of lane A in "manual" operation
Exercise 6: Management of spaces in a car park
