Preventing Wrong-Way Driving on Freeways

COURSE NO: C06-013
PDH CREDIT: 6
Preventing Wrong-Way Driving on Freeways
Course Highlights

This online engineering PDH course identifies the contributing factors to wrong-way crashes on freeways and develops promising, cost-conscious countermeasures to reduce these driving errors and their related crashes.  Factors found to be significant are alcohol impairment, age, gender, physical condition, driver's experience and knowledge, time of day, and interchange type.  Vehicle type, seat belt use, lighting, roadway alignment, driver age group, first vehicle contact point, and driver condition (blood alcohol concentration level) are shown to have an impact on crash severity.  Types of countermeasures such as signage, pavement markings, geometric design, and ITS vehicle detection systems are discussed. Applications to twelve specific interchanges are presented.

 

Driving the wrong way on freeways has been a consistent traffic safety problem since the interstate system was opened in the 1950s.  From 1996 to 2000 alone, over 1,700 people were killed and thousands more were injured in wrong-way crashes in the United States.  The average direct economic loss from such crashes is estimated to be over ten million dollars per year.

 

This 6 PDH online course is intended for civil and transportation engineers, design professionals, construction personnel and others concerned with the design and operation of highways.
