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 PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Considering the various constraints for constructing a roundabout
- Determining a preliminary lane configuration and selecting a roundabout category based on capacity requirements
- Performing the analysis appropriate to the roundabout selection category
- Determining the space requirements and feasibility
- Understanding the traffic operations at roundabouts
- Obtaining data required to evaluate the performance of a roundabout
- Estimating the capacity of the various roundabout configurations
- Applying measures of effectiveness determine the performance of a roundabout and estimating these measures
- Familiarizing with the different computer software packages available to implement the capacity and performance analysis procedures
In this professional engineering CEU course, you need to review Chapter 4, "Planning" and Chapter 5, "Operation", of the Federal Highway Administration Publication FHWA-RD-00-067, "Understanding Roundabouts".

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 PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Understanding research objectives and activities
- Learning about minimum retroreflectivity, glare and surround complexity
- Understanding the experimental variables, luminance levels and environmental conditions
- Evaluating experimental results of white-on-blue signs vs. white-on-brown signs
- Learning about the luminance threshold levels and minimum retroreflectivity levels
In this professional engineering CEU course, you need to review the Federal Highway Administration (FHWA) no. FHWA-HRT-08-029, "Minimum Retroreflectivity Levels for Blue and Brown Traffic Signs", April 2008.

This online engineering PDH course provides information on the design and post-implementation evaluation of Road Diets, and presents the decision-making process that helps practitioners determine whether Road Diets are a good fit for a certain corridor.
Four-lane undivided highways have a history of relatively high crash rates as traffic volumes increase and as the inside lane is shared by higher speed through traffic and left-turning vehicles. One option for addressing this safety concern is a “Road Diet.” A Road Diet involves converting an existing four-lane undivided roadway segment to a three-lane segment consisting of two through lanes and a center two-way left-turn lane (TWLTL). The reduction of lanes allows the roadway cross section to be reallocated for other uses such as bike lanes, pedestrian refuge islands, transit stops, or parking.
A Road Diet improves safety by including a protected left-turn lane for mid-block left-turning motorists, reducing crossing distance for pedestrians, and reducing travel speeds that decrease crash severity. Additionally, the Road Diet provides an opportunity to allocate excess roadway width to other purposes, including bicycle lanes, on-street parking, or transit stops.
This 4 PDH online course is applicable to transportation engineers who are interested in improving safety and reducing highway fatalities through the use of proven safety countermeasures including Road Diets.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Familiarizing with the basics of Road Diets
- Understanding the multidimensional benefits of Road Diets
- Learning about the geometric and operational designs of Road Diets
- Gaining a general overview on how to conduct a safety and an operational analysis to determine if the Road Diet is effective
- Exploring various case studies on feasibility determination decision-making

This online engineering PDH course presents the principles of engineering ethics that every engineer is expected to live by when practicing their profession.
Engineering ethics is (1) the study of moral issues and decisions confronting individuals and organizations involved in engineering and (2) the study of related questions about moral conduct, character, ideals and relationships of peoples and organizations involved in technological development (Martin and Schinzinger, Ethics in Engineering).
This course describes the fundamental legal concepts with which very engineer should be familiar. It also presents unique disciplinary case studies selected from across the nation, as well as hypothetical ethical challenges that demonstrate how difficult it can be to apply the code of ethics for engineers.
This 2 PDH online course is applicable to all professional engineers who are either required to fulfill 2 PDH in engineering ethics or are interested in broadening their understanding of what it means to practice and uphold the honor and integrity of their engineering profession while holding the utmost safety, health, and welfare of the public.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Understanding the common definition of ethics regarding engineering
- Learning about the important principles of the engineer’s professional responsibility
- Learning the do’s and don’ts through several ethical and disciplinary cases
- Understanding what it means to practise and uphold the honor and integrity of the engineering profession
