Final answer:
The sign on the right indicates drivers should slow down and yield to oncoming traffic, which improves pedestrian safety and can reduce traffic accidents.
Step-by-step explanation:
The sign on the right most likely signals drivers to slow down and yield to traffic on the main road when merging. This interpretation fits with standard road sign meanings which dictate that drivers should be cautious and allow other vehicles on the main road to continue before entering. This approach helps to enhance pedestrian safety, especially in busy intersections near campuses where students and other pedestrians cross. Moreover, the installation of traffic signals typically addresses concerns related to high traffic accident rates, making it easier to manage traffic flow and potentially reduce the frequency of accidents.
