In Street editing 
, you can use Remove Nodes 
to clean up streets by removing nodes individually or selecting many at once. When removing the nodes, you have the additional options to maintain the street layout and curve, or limit the deletion to only two-segment nodes while preserving the intersections.
You can also delete intersections and maintain the street segments connected to the intersection before deletion.
To remove street nodes , click Street editing and click Remove Nodes in the Tool Options window 
or press C+R. You can also click Graph > Remove Nodes in the main menu.
Remove street nodes
Click the Remove Nodes tool select single node or multiple nodes to remove:
In this case, the nodes are removed and a segment between the end point node at the top and the intersection node remains:
When you turn on the Fit to Curve toggle button in the tool options, CityEngine maintains the same street alignment and curve before the node or nodes were deleted.
Turn on the Remove joints only option to maintain the end point and intersection nodes in a street. When you select the end point and intersection nodes they are not selected:
The result is the same as the image above:
Remove intersection
Click the Remove Nodes tool and select an intersection node to remove it.
The segments connected to the intersection node are shortened to begin at the boundary of the removed intersection. This leaves the street alignments intact.

The Remove Nodes tool options include the following:
| Remove Nodes | |
