摘要： A method and apparatus for displaying a representation of a traffic roundabout having a central island surrounded by a circulatory lane is disclosed. The method involves receiving an operator selection of a design vehicle that is expected to use the roundabout, and receiving operator input of a design dimension for the roundabout, the design dimension defining a size of one of the central island and an outer perimeter of the circulatory lane. The method also involves generating a circulatory path of the design vehicle traveling within the design dimension along the circulatory lane, and generating vehicle extent locations associated with passage of the design vehicle along the circulatory path. The method also involves using the vehicle extent locations to compute a circulatory lane width, and generating display signals for causing the display to display an image representing the roundabout.

摘要： A method and apparatus for displaying a representation of a traffic intersection on a display of a computer is disclosed. The method involves receiving operator input defining a relative orientation between a first roadway and a second roadway, the first and second roadways forming an intersection area therebetween. The method also involves receiving an operator selection of a design vehicle that is expected to use the traffic intersection, the design vehicle being defined by a plurality of design vehicle parameters. The method further involves generating at least one turning path of the design vehicle through the intersection between the first roadway and the second roadway, and generating first vehicle extent locations associated with passage of the design vehicle along the at least one turning path. The method also involves generating an outer edge of the intersection area, the outer edge being generally aligned with selected ones of the first vehicle extent locations, and generating display signals for causing the computer display to display an image representing the traffic intersection.

摘要： A method, apparatus, media and signals for generating a computer representation of a three-dimensional swept envelope of a vehicle having a wheeled chassis operable to support a vehicle body for movement along a terrain is disclosed. The method involves receiving terrain data representing a 3D terrain, receiving data defining parameters of the vehicle, and receiving data defining a path for movement of the vehicle from an initial position on the terrain to a displaced position on the terrain. The method also involves disposing a computer representation of the vehicle on the 3D representation of the terrain at successive locations along the path using the parameters. Disposing involves determining points of engagement between wheels of the wheeled chassis and the 3D representation of the terrain to dispose the chassis with respect to the terrain, and determining a corresponding 3D location of the vehicle body with respect to the terrain. The method further involves generating a plurality of spatial extents of the vehicle at the successive locations, the spatial extents defining the 3D swept envelope of the vehicle when moving between the initial position and the displaced position. In another aspect a method for generating a computer representation of a three-dimensional swept envelope of an object moving along a guideway disposed with respect to a 3D representation of a terrain is disclosed.

摘要： A method and apparatus for generating a geometric layout of a traffic intersection is disclosed. The method involves receiving intersection capacity data, where receiving includes receiving an identification of a number of intersection legs associated with the traffic intersection, receiving a lane designation designating a plurality of lanes for accommodating permitted vehicle movements between the intersection legs, each lane having at least one associated permitted vehicle movement, and receiving lane width dimensions for accommodating an expected vehicular traffic volume associated with permitted vehicle movements on each of the plurality of lanes. The method also involves generating a geometric layout of the traffic intersection by receiving orientation data defining respective orientations of each of the intersection legs. The method further involves receiving intersection design criteria for designing the traffic intersection, for each intersection leg, combining the lane width dimensions and the intersection design criteria to determine extents of a roadway segment corresponding to the intersection leg, applying the intersection design criteria to generate corner geometry connecting between the roadway segments, and generating display signals for causing the geometric layout of the intersection to be displayed on a computer display.
