Final answer:
A traffic signal light on an emerging lane can improve safety by forcing vehicles to slow down, aid pedestrian crossing at appropriate times, and reduce accidents in areas with increased traffic volumes.
Step-by-step explanation:
A signal light can indeed improve safety by slowing down vehicles that would otherwise ignore the posted speed limits. With many drivers speeding through intersections, a signal light can serve as an intervention to regulate vehicle speeds and help manage traffic flow.
Considering pedestrian safety is also crucial. Without a signal light, pedestrians, including students and others, must navigate around fast-moving traffic. Introducing a signal light provides them with a proper time to cross, enhancing their safety.
Furthermore, the increasing accidents at problematic intersections, with some resulting in fatalities, underscores the necessity for improved control measures like traffic signals. With higher volumes of traffic due to nearby business and infrastructure growth, such as a manufacturing plant, retail developments, and event traffic changes, signal lights become even more essential for managing this increased demand and improving overall safety.
