Transportation Safety 15 PDH Discount Package 1

This online engineering PDH course will provide a background of bicycling including common vocabulary, concepts and knowledge.  The history of bicycling and improvement to the intermodal system will be discussed. 

Bicycle planning issues will be covered.  Utilitarian and recreational bicycling will be compared.  The basic principles to be considered for a transportation project will also be discussed.  The process of utilizing comprehensive planning, selection/development options will be provided as well as post design assessment.  Bicycle safety issues will be discussed.  The most common bicycle-motor vehicle crashes will be identified.  The types of bicyclists and their associated risks will also be covered.

This 4 PDH online course is currently intended for engineers and planners who are interested in learning more about bicycle planning and safety for use in roadway design.

This online engineering PDH course contains updated recommendations excerpted from the 2001 handbook. The recommendations do not constitute a new standard of required practice but are instead intended to supplement existing standards and guidelines in the areas of highway geometry, operations, and traffic control devices.  The recommendations provide guidance that is firmly grounded in an understanding of older drivers' and pedestrians' needs and capabilities, and can significantly enhance the safety and ease of use of the highway system for older persons, and for the driving population as a whole.

In 1998, FHWA published the Older Driver Highway Design Handbook, seeking to provide highway engineers with practical information linking the declining functional capabilities of older road users to the need for design, operational, and traffic engineering enhancements keyed to specific roadway features. Early experiences with the recommendations, including extensive feedback from local- and State-level practitioners through workshops conducted for departments of transportation across the country in 1999 and 2000, indicated a need to revise and update this resource. The result was a new handbook, the Highway Design Handbook for Older Drivers and Pedestrians, published in 2001.

The course also provides supplemental technical information not found in the full handbook.  The information is provided to explain (1) how specific diminished capabilities lead to age-related driving problems; (2) license renewal requirements and distinctions for older drivers in each State in the U.S.; and (3) how and why to conduct visibility measurements to ensure that various pavement marking treatments covered in the Handbook serve the needs of older road users. These materials are included to support practitioners in exercising the engineering judgment often called upon to reach implementation decisions.

This 7 PDH online course is intended for civil and transportation engineers concerned with the design and maintenance of road systems.

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.
