Transportation Engineering 12 PDH Discount Package 1

This online engineering PDH course presents a study that addresses various aspects of geosynthetic durability to develop procedures that could be used to predict long-term strength losses of geosynthetics used in highway applications. These procedures are essential to designers for allowing tensile capacity for geosynthetics used primarily in mechanically stabilized earth (MSE) retaining walls, reinforced soil slopes, and foundation stabilization.

 

This study was initiated to allow voiced concerns that stress-cracking potential was not being considered in developing the allowable tension load capacity for design when using high-density polyethylene (HDPE) geogrids. Stress cracking is a potential mode of failure occurring in thermoplastic materials that are under a sustained stress significantly lower than the material’s room temperature yield strength, resulting in quasi-brittle fracture of the material. This is also known as slow crack growth and environmental stress cracking (ESC) when in contact with certain aqueous solutions.

 

This 1 PDH online course is applicable to all civil engineers, highway design professionals, transportation planners, material manufacturers and all personnel interested in learning about geosynthetics for highway applications.

This online engineering PDH course presents information on defining high-occupancy vehicle (HOV) lane capacity, options for using available HOV lane capacity, and analyzing HOV exemption policies. It examines the potential impact of certain exempt vehicles on the operation of high-occupancy vehicles (HOV) facilities. The possible exempt vehicles examined in this course include environmentally friendly vehicles, and law enforcement, emergency services, and designated public transportation vehicles. It also presents the experience with the use of HOV lanes by these types of exempt vehicles. Finally, it examines the potential issues and approaches for allowing exempt vehicles to use HOV lanes.

 

Traffic congestion continues to be a major issue in metropolitan areas throughout the country. The agencies responsible for the surface transportation system in these regions use a variety of approaches and techniques to address concerns relating to traffic congestion, mobility, and air quality. The use of HOV facilities represents one approach in use or being considered in many urban areas.

 

This 5 PDH online course is applicable to traffic engineers, transportation planners, conceptual and detail designers, and other technical professionals who will be considering HOV exemption policies as well as monitoring and evaluating the use of HOV lanes by exempt vehicles.

This online engineering PDH course describes bottlenecks and explores near-term operational and low-cost construction opportunities to correct them.

 

Delays due to traffic congestion seem like an unavoidable, frustrating fact of life. Or are they—unavoidable, that is? This course focuses on traffic congestion caused by bottlenecks—which are specific locations on the highway system where the physical layout of the roadway routinely cannot process the traffic that wants to use it and results in localized, recurring congestion.

 

By focusing on relieving localized, recurring congestion at bottlenecks, this primer can help agencies identify the right fix for a particular bottleneck. What’s more, the right fix for a localized, recurring bottleneck is usually spot-specific, more effective, less expensive, and faster to implement than building a new facility.

 

This 6 PDH online course is applicable to traffic engineers and planners, conceptual and detail designers, and other technical professionals who are interested in gaining a better understanding in traffic bottlenecks operational improvements.
