Final Answer:
Traffic signs, traffic signals, and road markings are set up to regulate, guide, and inform drivers and pedestrians about road conditions and rules.
Step-by-step explanation:
Traffic signs, traffic signals, and road markings serve crucial roles in maintaining order and safety on the roads. They are strategically placed to regulate the flow of traffic, guide drivers, and provide essential information about road conditions and rules. Traffic signs convey specific messages, such as speed limits, warnings, and directional information. Traffic signals control the right of way at intersections, managing the movement of vehicles and pedestrians. Road markings, including lane dividers and crosswalks, help organize and guide traffic.
The setup of these elements is a coordinated effort by transportation authorities to create a standardized and universally understood system that enhances road safety, minimizes congestion, and promotes efficient traffic flow.
