Answer :
Final answer:
A 'merge ahead' sign on a roadway indicates that two separate traffic flows will soon unite, necessitating vigilance from drivers. Meanwhile, at congested intersections, traffic signals can significantly improve traffic flow management and pedestrian safety by enforcing speed limits and defining appropriate crossing times.
Explanation:
The sign 'merge ahead' is usually used to indicate locations where two separate traffic lanes come together into one, common in highway or expressway systems. When you see a merge sign, it means vehicles will soon be entering your traffic flow from the side, so it's essential to be attentive and prepared for this.
This scenario is similar to a heavily congested intersection where a traffic signal could be beneficial for controlling the traffic, based on the information provided about the increase in traffic near the intersection. A traffic signal would require vehicles to obey the defined speed limit, and it would help manage the traffic flow from the manufacturing plant and businesses, as well as the routing of college football game traffic. It provides an orderly process of letting vehicles and pedestrians take their turns, thereby averting possible accidents.
Pedestrian safety is another essential aspect here. Many people, including students, must cross this intersection regularly, hence, a traffic signal would enable them to cross safely and at appropriate times.
