Oregon Transportation 30 PDH Discount Package 2

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 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 engineering PDH course describes the research activities and consequent findings related to the development of recommendations for maintained retroreflectivity (MR) levels for white-on-blue signs and white-on-brown signs. It also includes an investigation related to MR levels needed for complex visual conditions that include glare from oncoming headlamps and fixed roadway lighting.

In 2003, the Federal Highway Administration published research recommendations for minimum MR levels for traffic signs. The recommendations included most sign types but not white-on-blue signs or white-on-brown signs. In addition, the 2003 MR levels were based on conditions representing dark rural environments.

This 4 PDH online course is applicable to all traffic engineers, transportation planners, sign manufacturers and all personnel interested in learning about or who are involved in the planning and determination of minimum retroreflectivity levels for traffic signs.

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 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 presents guidelines on the design of traffic elements, illumination, and landscaping associated with roundabouts.

The design of these elements is critical in achieving the desired operational and safety features of a roundabout, as well as the desired visibility and aesthetics.

This 3 PDH online course is applicable to traffic engineers, transportation planners, conceptual and detailed designers, and other technical professionals who are involved in the traffic design and landscaping of roundabouts.
