Expressways routinely have lower crash frequency rates than other roadway types.
a) True
b) False
The correct answer and explanation is:
Correct Answer: a) True
Expressways generally have lower crash frequency rates compared to other types of roadways, such as rural roads, urban streets, or highways. This is because expressways are designed with several safety features to minimize accidents. These features include higher speed limits, controlled access points (on and off ramps), and fewer intersections. The design of expressways reduces the likelihood of head-on collisions, turning accidents, or conflicts between different types of vehicles.
One of the key factors contributing to lower crash rates on expressways is the separation of traffic flows. For example, expressways often have lanes designated for specific types of vehicles, such as trucks and passenger cars, which reduces the potential for accidents due to vehicle incompatibility. In addition, expressways are usually designed to be free of sharp curves or intersections, which further reduces the chance of accidents occurring.
The limited access to expressways also plays a crucial role. With fewer entry and exit points, there is less chance for vehicles to suddenly merge or stop unexpectedly, which can lead to accidents. Furthermore, expressways typically feature clear signage and road markings, helping drivers to navigate safely and effectively.
Despite these advantages, expressways are not without risk. Factors such as high speeds, driver inattention, and inclement weather can still lead to serious accidents. However, overall, the engineering and design improvements make expressways safer than other types of roads, leading to fewer accidents per mile traveled. This is why expressways tend to have lower crash frequency rates.
