Modify times, terms, and demands of traffic flows - Exercise
Task 1: Set a speed restriction on a lane due to site works
- Create a TSA – Traffic Study Area with limits as close as possible to the intersection (allowing the demand zones to display).

- Right-click on the canvas to open the Traffic Analyst Panel.

- Zoom and move the canvas to get a view that allows you to see all the zones as close as possible.
- Select the View tab on the righthand side menu, create new, and rename as you consider.

- Make sure you have the Edit mode selected at the bottom of the View tab.

- Switch off the Images layer under the Layer tab on the righthand side menu. The Highlighter column represents the active layer selection – Images appear as Active on the below image. The cell will be black if the layer is switched off.

- On the top left main menu bar, go to Parameters, then Restrictions.

- Select the tab SpeedControl, select the “plus” sign to create a New SpeedControl, add a description, and set the speed column value to a noticeable one (very high or very low).
- Click Apply and OK.
- Select ONE external lane by pressing Control and double-clicking over the lane selected or pressing Control and wheel-clicking over the lane selected. Select a lane approaching the intersection.

- Right-click over any area selected and select Adjust.
- On the Adjust menu, select the Lanes tab. Under the SpeedControl column, select the speed limitation created on the Restriction menu.

- Click Apply and OK.
- Run the simulation first in TAP and then in InfraWorks.
