Introduction. The cross section of a roadway is composed of several distinct parts. They are: the median (for divided roadways); the lane; the shoulder; the inslope; the roadside ditch; the backslope and; the clear zone; the bridge; When the selection .

Introduction - No change. Practical Design (Technical, Policy, and Program) - Added sections .
The geometric cross section is composed of multiple lateral design elements such as lanes, shoulders, medians, bike facilities, and sidewalks. The designer’s task is to select, size, and document these elements appropriately. There is flexibility in the selection . D. Section Deleted E. Stopping Sight Distance F.

The four activities provided in this chapter cover information in Chapter 4 of AASHTO Green Book and Chapters 3 and 5 of Roadside Design Guide. Specific subjects covered are cross sectional elements.

The TCDH and the AASHTO Policy on Geometric Design of Streets and Highways also give dimensions for minimum safe sight triangles at grade crossings.
vertical curves) and horizontal alignment (tangents and curves), the roadway cross-section (lanes and shoulders, curbs, medians, roadside slopes and ditches, as well as sidewalks).
Any discussion of highway roadside clear zones needs to start with a general definition of what is a clear zone. The AASHTO Roadside Design Guide 1 defines clear zone as "the total roadside border area, starting at the edge of the traveled way available for safe use by an errant vehicle.” But AASHTO is not clear about what defines "safe".
Cross Section Elements CHAPTER 4 CROSS SECTION ELEMENTS PAVEMENT Surface Type The selection of pavement type is determined by the volume and. The term "clear zone" is defined as the total roadside border area, starting at the edge of through traveled way, available for safe use by errant vehicles.
Safe use generally means the slope is. Safety and Traffic Design March General Systematic upgrading of roadside features and elements will be designed to meet current nationally accepted standards for crashworthiness. It is FLH’s conviction that the respective statutory missions of FLH and partner agencies relating to enhancing safety.
The cross sections are also hand drawn, thus are of limited accuracy such as the cartoonish like cross section of Lake Superior and given the acutely dominate water environment, perhaps not the best choice of topics for a roadside geology text less addressing, e.g.

The need to connect and blend all the envi- ronments involved in the traveled way and the context will greatly influence the roadside design. Cross Section and Roadside Width Determination The desired width and cross-section elements of the roadside.
