Refers to the more general and abstract parts of the process |
Planning |
|
|
Refers to more detailed and concrete plan |
Design |
|
|
Refers to establishment of horizontal and vertical alignments and cross section, based on considerations such as operating characteristics of vehicles, design standards, and drainage. |
Geometric Design |
|
|
The distance required to see an object 0.15 m high on the roadway. |
Stopping sight distance |
|
|
The distance required to see an oncoming vehicle of a certain minimum size. |
Passing sight distance |
|
|
Defined as the maximum safe speed that can be maintained over a specified section of highway when conditions are so favorable that the design features of the highway govern. |
Design speed |
|
|
Refers to drawings, usually accompanied by notes, of various aspects or components of the design. |
Plans |
|
|
Are written instructions detailing how the facility is to be constructed |
Specifications |
|
|
Include cost estimates for various parts of the project and are used to evaluate the acceptability of bids and the financial feasibility of the project |
Estimates |
|
|
This is a drawing of the facility as it would look to an observer directly above it. |
Plan View |
|
|
This drawing has elevation as its vertical axis, and horizontal distance, as measured along the centerline of the facility, as its horizontal axis. |
Profile |
|
|
This view has elevation as its vertical axis and horizontal distance, measured perpendicular to the centerline, as its horizontal axis. |
Geometric Cross Section |
|
|
This applies to curved facilities, such as highways or railways, only. It consists of a graph with roadway or railway cross-slope versus horizontal distance. |
Superelevation diagram |
