What would likely not be considered a factor when evaluating roadway design for safety improvements?

When evaluating roadway design for safety improvements, construction regulations are typically not considered a direct factor influencing the design's safety effectiveness. The primary focus in such evaluations generally lies on elements that directly impact how road users interact with the roadway and their surroundings.

Traffic volume plays a crucial role, as higher volumes can lead to an increased likelihood of accidents. Weather conditions are also significant, as they can affect visibility and road surface conditions, impacting driver behavior and safety. The use of Crash Modification Factors (CMFs) provides data-driven insights into how various design elements influence crash rates, which is central to assessing safety improvements.

Construction regulations pertain more to the mandatory standards and guidelines that must be followed during the construction process, rather than the safety effectiveness of road designs themselves. While these regulations ensure that construction methods are safe, they do not directly evaluate the roadway's design in terms of its ability to prevent accidents or protect users once the road is operational.
