Crossroad

This element allows to handle several traffic lights and make them work through cycles.

Each traffic light can be linked to a crossroad thanks to its parameter Crossroad.

Link new traffic lights

When you create the element Crossroad, it is not linked to any traffic light. Thus, it cannot control any. You will have to add-up each traffic light to your crossroad. Each traffic light can only be linked to one crossroad.

• First, select the traffic light that you want to link to your crossroad.

• Then, in the Parameter tab associated with your traffic light, find the parameter Crossroad and select the exact name given to your crossroad.

• Don't forget to click Save in the Parameter tab to take your change into account.
• Now the link should appear in Edit Mode, as an orange line.

• Repeat the process for each traffic light that you want to link to your crossroad.

Cycle table description

The parameter Cycle table allows to edit a whole table which gives a complete description of the cycles of a crossroad. When clicking on the edit icon you will access a table as the one below:

Here is a description of each column:

Cycle

A cycle is defined by a period of time in which each traffic light have a defined color. Each cycle is identified with a number (or index). The first cycle of the cycle table will be 1, then, the index will be incremented for each new cycle added. The cycle table will go through all cycles, and then loop starting from the first cycle.

You can add and defined a new cycle by clicking on the add button. You can also remove existing cycles by clicking on the button.

Time

The time column will define how long a cycle should be, in ms. For example, a value of 5000 for a given cycle means that the current cycle will last for 5 seconds before switching to the next cycle.

Traffic lights

For each traffic light that you have linked to your crossroad, you will have an additional column representing a traffic light for each cycle you will have to define the color of the given traffic light.
