CE-101 Human Factors in Road Safety

Human Factors in Road Safety

Human Factors in Road Safety

Human Factors in Road Safety PDH online course is a part of the Civil and Transportation course category. The purpose of this course is to introduce the core elements of human factors that affect the interaction between drivers and roadways. With an understanding of how drivers interact with the roadway, there is more potential for roadways to be designed and constructed in a manner that minimizes human error and associated crashes. This course can be taken as part of both Professional Engineering as well as the TPCB license renewal continuing education requirements.

The interdisciplinary study of human factors applies knowledge from the human sciences such as psychology, physiology, and kinesiology to the design of systems, tasks, and environments for effective and safe use. The goal of human factors is to reduce the probability and consequences of human error within systems, and associated injuries and fatalities, by designing with respect to human characteristics and limitations.

In transportation, driver error is a significant contributing factor in most crashes. For example, drivers can make errors of judgment concerning closing speed, gap acceptance, curve negotiation, and appropriate speeds to approach intersections. In-vehicle and roadway distractions, driver inattentiveness, and driver weariness can lead to errors. A driver can also be overloaded by the information processing required to carry out multiple tasks simultaneously, which may lead to error. To reduce their information load, drivers rely on a-priori knowledge, based on learned patterns of response; therefore, they are more likely to make mistakes when their expectations are not met. In addition to unintentional errors, drivers sometimes deliberately violate traffic control devices and laws.
