Intersection design for V-nasClair

Automatically create 3D models of intersections on V-nasClair.

◆ By inputting minimum conditions such as linearity and width composition, a 3D model of the intersection is automatically created. ◆ It also supports the design and diagramming of various intersections such as T-junctions and roundabouts. ◆ Intersections can be edited on a dedicated screen. ◆ You can directly edit by simply selecting the areas you want to change (guidance paths, merging circles, corner cut lines, etc.). ◆ The position of the stop line is changed, and at the same time, the "crosswalk" and "road markings" are updated. ◆ Longitudinal and transverse profiles are automatically calculated and created from road surface contour lines. ◆ The current longitudinal and transverse conditions are automatically obtained from a 3D terrain model, and the slopes at the intersection are automatically expanded. * To operate Intersection Design for V-nasClair, V-nasClair version 2020.2 or higher (64-bit version), Basic Suite, and ROAD_Kit are required.

basic information

● By simply indicating the intersection drawing at the points where the linear paths intersect, a 3D model of the intersection is automatically created. The shape of the intersection is updated in real-time according to changes in design conditions, while checks for lane discrepancies and interference with guiding paths are performed simultaneously to prevent setting errors. ● If the intersection is a T-junction, it is automatically recognized as a T-junction intersection, and a 3D model of the T-junction is automatically created. A roundabout 3D model can also be automatically created just by indicating it as a roundabout intersection. ● The position of the stop line can be considered using methods such as mouse operation, input of measurement points, and distance input from the shoulder line. Changes to the stop line position will automatically update elements such as "crosswalk" and "road markings" simultaneously, and this automatic update also applies in curved sections. ● The primary and secondary relationships of intersecting roads, longitudinal profiles, and cross slopes are automatically calculated and created for surface contour lines (editable). The sag points of the intersection and road are automatically calculated and flagged, which can be used for considering the position of drainage pits at the intersection and for preparing construction plans (pavement finish heights). ● The current longitudinal and transverse conditions are automatically obtained from the 3D terrain model, allowing for the significant reduction of effort in slope development for earthworks. The designed and edited intersection shape can be easily checked in a 3D model viewer.
