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.

- Designing methods to avoid vehicle path overlap
In this professional engineering CEU course, you need to review Chapter 6, "Geometric Design", of the Federal Highway Administration Publication FHWA-RD-00-067, "Understanding Roundabouts".
This online engineering PDH course presents the factors that lead up to the decision to construct a roundabout with an approximate configuration at a specific location, preceding the detailed analysis and design of a roundabout. By confirming that there is good reason to believe that roundabout construction is feasible and that a roundabout offers a sensible method of accommodating the traffic demand, these planning activities make unnecessary the expenditure of effort required subsequently.
This course also presents methods for analyzing the operation of an existing or planned roundabout. These methods allow a transportation analyst to assess the operational performance of a facility, given information about the usage of the facility and its geometric design elements. An operational analysis produces two kinds of estimates: (1) the capacity of a facility, i.e., the ability of the facility to accommodate various streams of users, and (2) the level of performance, often measured in terms of one or more measures of effectiveness, such as delay and queues.
This 5 PDH online course is applicable to traffic engineers, transportation planners, conceptual and detailed designers, and other technical professionals who are involved in the planning and operation of roundabouts.

This online engineering PDH course describes the strategy involving the application of shoulder rumble strips (SRS) and centerline rumble strips (CLRS) in combination. This strategy is intended to reduce the frequency of crashes by alerting drivers that they are about to leave the travelled lane. While research has been published on the safety effectiveness of SRS or CLRS used in isolation, the effectiveness of the combined treatment has not been shown.
Geometric, traffic, and crash data were obtained at treated two-lane rural road locations in Kentucky, Missouri and Pennsylvania. To account for potential selection bias and regression-to-the-mean, an Empirical Bayes (EB) before-after analysis was conducted using reference groups of untreated two-lane rural roads with similar characteristics to the treated sites. A slightly different approach was required for the analysis of the treatment sites in Missouri, which is installing rumble strips on two-lane rural roads whenever a resurfacing project is undertaken. As a result, a suitable reference group with no rumble strips for this road type presently or in the near future did not exist. The analysis also controls for changes in traffic volumes over time and time trends in crash counts unrelated to the treatment.
This 4 PDH online course is intended for traffic engineers, design professionals and construction personnel who are involved in the design and application of centerline and shoulder rumble strips.
