Allsite.ai provides basic road layout tools, allowing you to quickly run a Level AI model that has a 'right of way' and single road lanes. It allows definition of longitudinal grades and, if you have a profile associated with the alignment will update the vertical geometry for review (review only, as the roads elevation is set via feature lines for basic road corridors in the Level AI produced proposed surface).
In the future, more basic 'pseudo road corridor' types will be supported including 2 lane boulevards with an island in the middle.
Getting Started
To get started you will need a polylines or alignments for your road centrelines.
Select them all and convert them to Allsite "Road (Layout Assist)" objects
Set the layout related parameters (see below) for things such as lane width, 'right of way' (ROW) width, cul-de-sac radius, intersection radius.
Set longitudinal grade information (same as for full road corridors)
Run Layout assist
Review modifier locations and configure settings as (same as for full road corridors)
Tip: You can use QSELECTPROPERTYSET command to select roads of a particular type and configure parameters (ie select all LOCAL road alignments and set their intersection radius)
Road Layout Settings
Setting | Description |
Cul-de-sac radius | The radius for cul-de-sacs (if any) on this road |
Intersection radius | The intersection radius. The 'lesser' road type will take precedence for radius (for example a LOCAL road intersecting with an ARTERIAL road will use the LOCAL road's radius) |
Road width (left and right) | Width of the road lane (to left / right of centre) Note: if leave road width right blank, just sets both sides of road to left width. |
Right of way (ROW) width | Width of the right-of-way (to left and right of centre) must be greater than the road width. |
