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 online engineering PDH course provides guidance and recommended practices on planning and designing ramps with freeway facilities. The overriding objectives of effective planning and design are to minimize congestion, improve safety and enhance overall mobility.

This course also describes in greater depth the issues and concepts specific to ramp planning and design. This information will help practitioners develop a comprehensive understanding of project planning and design, and it will help ensure that projects are implemented successfully.

This 4 PDH online course is applicable to traffic engineers, transportation planners, managers, and other technical professionals who are involved in ramp planning and design in support of the overall ramp management strategy.

This online engineering PDH course provides information on roundabout at the planning, design, construction, operations and maintenance levels. It also includes the procedures considered for selecting and assessing the appropriateness of a roundabout.

A modern roundabout is one of the three types of circular intersections. However, roundabouts have demonstrated substantial safety and operational performance over other forms of intersection control. This course focuses on two categories of roundabouts: single-lane and multilane roundabouts. It is intended to ensure consistency across the State in the implementation of roundabouts at new installations and to provide safe and efficient traffic operations in the case of retrofit/redesign or reconstruction of existing intersections.

This 7 PDH online course is applicable to transportation engineers, road designers, planners, contractors and professionals who are interested in the design, operation, construction and maintenance of roundabouts.

This online engineering PDH course provides an overview of the main operations, logistics, and technology strategies for improving urban freight mobility and delivery.

The course covers the challenges and opportunities associated with urban freight transport, as well as various strategies and technologies that can be used to improve freight mobility in urban areas or to minimize its impacts on others. Operations, logistics, and technology (OLT) strategies represent a set of practices that can be applied to improve the movement of goods and the quality of life of urban residents.

The course will help in understanding potential applications of OLT strategies in order to improve urban freight management and mobility through sharing noteworthy practices that have been implemented successfully.

This engineering online PDH course will establish conditions under which, when an engineering failure has occurred, it can be attributed to negligence.    

Five causes of failure are proposed: negligence, rare failure mode, overlooked failure mode, new (previously unrecognized) failure mode, and incorrect assessment of a known risk. Negligence is the only cause that involves failing in an ethical duty.  These concepts are illustrated with five case studies of failures ranging from gross negligence to absolutely unforeseeable events: 1) the Great Boston Molasses Flood of 1919, for which a new possible cause was identified 95 years later (2014); 2) a building collapse in Bangladesh in which over 1,000 people died—one of the worst structural engineering disasters in history; 3) a meteorite strike of a private residence; 4) the crash of the British-French Concorde supersonic airliner, caused by an unlikely tire blow-out; and 5) radiation overdoses received by patients treated by the Thorac-25 medical linear accelerator, caused by errors in the software controlling the machine.
