Expressways routinely have lower crash frequency rates than other roadway types.
a) True
b) False
The correct answer and explanation is:
The correct answer is a) True.
Expressways, or freeways, tend to have lower crash frequency rates compared to other types of roadways. This is primarily because of their design and operational features, which make them safer for high-speed travel.
First, expressways are designed with limited access points. They typically have fewer intersections, driveways, or other conflicting road uses, reducing opportunities for accidents. By limiting the entry and exit points to controlled access ramps, expressways minimize potential points of collision that occur more frequently in areas with intersections or streetlights.
Another safety feature is the lane separation and higher lane width found on most expressways. This reduces the likelihood of side-swipe accidents, especially at high speeds. The clear division between lanes and often a physical barrier between opposing directions of traffic also helps reduce head-on collisions.
Additionally, expressways are engineered for optimal visibility, with clear signage, road markings, and lighting, all contributing to driver awareness and reducing error. These roads are also designed to accommodate higher speeds safely, with features like wide shoulders and smooth curves, reducing the chances of accidents caused by sharp turns or narrow lanes.
Moreover, expressways are generally less congested than urban or local roads, where more vehicles, pedestrians, and cyclists interact. In comparison, the traffic flow on expressways tends to be more uniform, reducing the chances of sudden stops or unpredictable vehicle movements that lead to crashes.
However, while expressways do experience lower crash frequency rates, the severity of crashes on these roads can be higher due to the higher speeds involved. Nonetheless, overall, expressways are safer than other types of roads.
