Roadway Design 12 PDH Discount Package

This online engineering PDH course focuses on the geometric design of vertical alignments for modern roads and highways.

Roadway vertical alignments are a combination of various parabolic curves and connecting tangent grades. Along with the roadway cross section (lanes, shoulders, curbs, medians, roadside slopes, ditches and sidewalks) and horizontal alignment (tangents and curves), the vertical alignment (grades and vertical curves) helps provide a three-dimensional roadway model. Its ultimate goal is to provide a safe, smooth-flowing facility that is crash-free.

In today's environment, designers must do more than apply design standards and criteria to 'solve' a problem. They must understand how various roadway elements contribute to safety and facility operation, including the vertical profile.

This 4 PDH online course is applicable to traffic or transportation engineers interested in learning about the principles to be considered when designing roadway vertical alignments.

This online engineering PDH course summarizes and highlights the geometric design process for modern roadway intersections. It presents the general guidelines for at-grade intersection design and provides an in-depth look at the principles to be considered when selecting and designing intersections. The contents of this document are intended to serve as guidance and not as an absolute standard or rule.

Intersections are unique roadway elements where conflicting vehicle streams (and sometimes non-motorized users) share the same space. This area encompasses all modes of travel (pedestrian, bicycle, passenger vehicle, truck and transit) as well as auxiliary lanes, medians, islands, sidewalks and pedestrian ramps. These may further heighten the accident potential and constrain the operational efficiency and network capacity of the urban street system. However, the main objective of intersection design is to facilitate the roadway user and enhance efficient vehicle movement.

This online engineering PDH course focuses on the geometric design of horizontal alignments for modern roads and highways. In today's environment, designers must do more than apply design standards and criteria to "solve" a problem. They must understand how various roadway elements contribute to safety and facility operation, including the horizontal alignment.

The roadway horizontal alignment is a series of horizontal tangents (straight roadway sections), circular curves, and spiral transitions. It shows the proposed roadway location in relation to the existing terrain and adjacent land conditions. Together with the vertical alignment (grades and vertical curves) and roadway cross-sections (lanes, shoulders, curbs, medians, roadside slopes, ditches and sidewalks), the horizontal alignment (tangents and curves) helps to provide a three-dimensional roadway layout.
