Answer :
Final answer:
The statement is true; pentagon-shaped signs are used to mark school zones and indicate school crossings, and their role in pedestrian safety is significant. Traffic signals at intersections also contribute to the safety of pedestrians, especially in areas with high vehicle traffic.
Explanation:
The statement regarding the shape and purpose of the pentagon-shaped sign in school zones is true. The five-sided sign is indeed used to mark school zones and to warn drivers about nearby school crossings. These signs sometimes include horizontal lines that signify the exact location of the crosswalk, which helps ensure pedestrian safety, especially in areas where students and others frequently cross the street. Installation of such signs, as well as traffic signals, play a critical role in managing vehicle speeds and providing safe crossing points for pedestrians in high traffic areas, such as those near schools and college campuses.
For example, before the installation of a traffic signal at a specific intersection described as Clay Street and Eagle Avenue, there was a significant risk to pedestrians due to speeding vehicles. The installation of the traffic signal improved safety considerably by allowing pedestrians, including students, to cross at appropriate, regulated times. Furthermore, the presence of increased traffic near the intersection, possibly due to the opening of a manufacturing plant and the expansion of businesses, further underscores the necessity of implementing traffic control measures to enhance safety.
