What is one potential issue that may arise with inductance loops in certain weather conditions?

In the context of inductance loops, pavement cracking from freeze-thaw cycles can indeed be a significant issue. Inductive loops are typically embedded in the pavement to detect the presence of vehicles, and they work by sensing changes in inductance as vehicles pass over them. When weather conditions lead to freeze-thaw cycles, the repeated expansion and contraction of moisture within the pavement can cause stress that ultimately leads to cracking.

This cracking can disrupt the integrity of the inductive loop installation, potentially leading to malfunctions in vehicle detection. When the loops are damaged, it may result in costly repairs or replacements, and could also contribute to traffic signal inefficiencies, as the signals may not operate optimally without accurate vehicle detection.

In contrast, other options like increased material costs or malfunctioning during heavy snow focus on different aspects that may not directly relate to how inductive loops specifically interact with the environmental conditions affecting pavement integrity.
