Ohio Transportation and Ethics 30 PDH Discount Package 2

This online engineering PDH course presents the fundamental design principles common among all roundabout types. This course also presents detailed design considerations specific to multilane roundabouts, rural roundabouts, and mini-roundabouts.

Designing the geometry of a roundabout involves choosing between trade-offs of safety and capacity. Roundabouts operate most safely when their geometry forces traffic to enter and circulate at slow speeds. Horizontal curvature and narrow pavement widths are used to produce this reduced-speed environment. Conversely, the capacity of roundabouts is negatively affected by these low-speed design elements. As the widths and radii of entry and circulatory roadways are reduced, the capacity of the roundabout is also reduced.

Furthermore, many of the geometric parameters are governed by the maneuvering requirements of the largest vehicles expected to travel through the intersection. Thus, designing a roundabout is a process of determining the optimal balance between safety provisions, operational performance, and large vehicle accommodation.

This 4 PDH online course is applicable to traffic engineers, transportation planners, managers, and other technical professionals who are involved in the geometric design of roundabouts.

This online engineering PDH course introduces and describes four commonly used strategies that may be implemented to better manage traffic on and adjacent to freeway ramps. In doing so, this course lays the foundation from which practitioners may successfully develop, select, operate and maintain strategies and plans.

These four strategies give agencies the ability to control the rate that traffic is allowed to enter the freeway facility; temporarily or permanently restrict traffic flow, provide priority to special vehicle uses, and implement treatments at the ramp-arterial terminal to improve traffic operations on and along ramps and adjacent arterials. For each strategy, a number of associated techniques and approaches exist, some of which will prove to be better than others at fulfilling agency goals and objectives.

This 4 PDH online course is applicable to traffic engineers, transportation planners, conceptual and detail designers, and other technical professionals who are interested in gaining a better understanding in ramp management strategies.

This online engineering PDH course describes operating managed lane projects through a case study approach, highlighting best practices of the projects and the lessons learned. It also presents emerging issues and knowledge gaps. The intent of this course is to provide a cross-cutting study of the issues and experiences of various agencies as managed lane projects are implemented and policies are drafted.

Increasing traffic congestion in the major metropolitan areas is costing billions of dollars each year in lost productivity, wasted fuel, increasing air pollution and hours of delay. Adding new general-purpose lanes is increasingly difficult because of factors such as construction costs, limited right-of-way, environmental and societal concerns. As a result, agencies are looking for solutions to improve the flow of traffic on existing facilities.

One concept being considered is that of "managed lanes". Managed lanes employ various strategies to improve flow and maximize the efficiency of the freeway system. Common types of managed lanes include high-occupancy vehicle (HOV) lanes, high-occupancy toll (HOT) lanes, value priced lanes, or exclusive or special use lanes.

This 4 PDH online course is applicable to traffic engineers, transportation planners, conceptual and detail designers, and other technical professionals who are involved with developing and operating managed lane facilities in freeway corridors and are interested in gaining a basic understanding of the issues associated with developing managed lane projects.

This online PDH course primarily covers engineering countermeasures for horizontal curve safety that are relatively low-cost, such as signage and pavement markings.

This course is intended to provide information specifically relating to lower volume two-lane roads and the agencies that manage them. It will help transportation agencies and their crews understand the available countermeasures and how to select and apply them.

This online engineering PDH course refers to military design requirements and objectives and provides guidance on the general provisions and geometric design criteria for the design of roads, streets, bridges, walks, parking, residence drives and storage areas. It discusses how geometric design deals with the dimensions of the visible features of a facility such as alignment, sight distances, widths, slopes, and grades.

This 3 PDH online course is applicable to civil and traffic engineers, technical professionals and construction personnel who are interested in gaining a better understanding of geometric design for roadways, walkways and open storage areas.

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.

In this online engineering PDH course, background on the philosophical models that guide ethical behavior is discussed and then applied to specific situations in engineering codes of ethics. This course is based on the American Society of Mechanical Engineers Professional Practice Curriculum, Volume 8, Section: Engineering Ethics.

Many engineering organizations have drafted codes of ethics to which their members are required to commit.  Generally, these codes are quite similar and are based on a few fundamental principles which provide guidance to professional engineers in common situations. Nevertheless, there are many difficult or ambiguous situations in which the best ethical solution is difficult to determine.

This 2 PDH online course is intended primarily for engineers seeking to learn ethical principles and how to apply them to their professional practice.
