To add a component road

Choose a component road assembly to draw in-canvas.

1. Click Create Transportation Component Road (Ctrl + R).
2. Display the Stack if it is not already displayed.
3. Checkmark your preferred component road creation method in the Stack. Available options are an Element Based or PI Based sketch method. Tip: Hover over the icon to view an animated tooltip about each method.

• PI Based: Using this method, you draw the road's alignment by placing points of intersection at each click location. InfraWorks will automatically generate horizontal road curves or spiral curve spirals where permitted by design geometry.
• Element Based: Using this method, you draw the road tangents and curves individually.

4. Optionally, click the orange hyperlinked text in the Type section of the Stack to choose a different component road assembly style to sketch.

5. Single-click in-canvas to place points. Each click places an individual point along the component road's alignment. Sketch guides will display tangents in blue and curve sections in green, and will report the total component road length in canvas. The curve length and curve radius values are displayed in annotations; the curve radius annotation is directly editable in canvas.

   

   Tip: Press Ctrl + L to constrain the length value for a line or curve as you are sketching.

6. Right-click while sketching to choose default layout options.

7. Double-click to finish drawing the component road. After you have added the component road, you can:

   • Select the entire assembly or individual components and modify their attributes in the Stack.
   • Use in-canvas grips to adjust vertical and horizontal geometry as needed.
   • Tip: Hold Shift while modifying existing curves in a roadway to keep horizontal curve geometry fixed to the tangent.
   • Insert components into the component road assembly if you want to add additional components such as lanes, medians, shoulders, sidewalks, or bikeways.
   • Place decorations on your component road.

Additional information

• Road start point and endpoint locations are defined by the order in which a user draws the road. First click defines the start point and double-click defines the endpoint of the road.

• When you add a component road, the design speed property determines which set of criteria to use for parameters such as minimum and maximum radius, spiral length, and tangent length. After a component road has been added, you can modify its horizontal and vertical geometry, as well as the design speed. The default design speed is based on the function selection. Local roads are set to 45km/hr and freeway metric roads are set to 110km/hr.

• To extend an existing component road, click the end of the original road as your starting point for the extension. The extension snaps to the existing road.
