Final answer:
Temporary traffic control signs are categorized into Regulatory, Warning, and Guide signs. Traffic signals are important for controlling vehicle speed, ensuring pedestrian safety, and reducing traffic accidents.
Step-by-step explanation:
Temporary traffic control signs are divided into three categories: Regulatory signs, Warning signs, and Guide signs. Regulatory signs include commands such as Stop signs and Speed Limit signs, indicating legal obligations drivers must follow. Warning signs provide alerts about potential hazards ahead, like curve or pedestrian crossing signs, to ensure driver and pedestrian safety. Lastly, Guide signs offer navigational information to guide drivers along their route, such as highway markers and exit signs.
Importance of Traffic Signals
A traffic signal plays a significant role in enforcing speed limits, enhancing pedestrian safety, and reducing the incidence of traffic accidents. Speeding vehicles are more inclined to slow down in the presence of a traffic signal. Pedestrians, including students who may need to cross busy roads to access campus, benefit from designated crossing times facilitated by signals. With the installation of a traffic signal, the risk of accidents at intersections can decrease significantly, potentially saving lives.
