This is the second tutorial in the blog about how to use the new feature for laying roads, introduced in SCARM v. 0.9.24. This article will provide you with information about how to make intersections with some additional options.
The basic piece for creating of road crossings is called “Intersection”. It is a 90 degree 4-way junction, which in its simple form may be used as follows:
Simple road crossing
You can also make a 3-way T-shaped junction by closing the missing road with “Road end” part as follows:
This is the most compact form, but if you want to be closer to the real world, you will need a rounded corners in order to allow bigger vehicles to make proper turns. These sections are called “IS Adapter” and have rounded areas on left, right or both sides. By using of the adapters, you may get the following:
Simple road crossing with rounded corners
|If you want to rotate IS adapter piece, you will need first to place it on the plot and then to move and attach it to the desired road section.
You can also just drag-and-drop the IS adapter piece form the button to the drawing plot with the mouse and attach it as you wish.
The 3-way T-shaped junction with rounded corners will look as follows:
Simple T-junction with rounded corners
The basic intersection part has a roundabout option. When used, you can make a small traffic circle like the following:
Simple road crossing with roundabout in the center
As before, the roundabout may be with T-shape where the missing road needs to be closed with “Detour” part as follows:
Simple T-junction with roundabout in the center
The next tutorial will give you even more information about how to use the crossing road sections in SCARM.
