Final answer:
The described efforts like using traffic cones and flashing lights are part of traffic management, aimed at controlling the flow of traffic and ensuring road safety by enforcing speed limits and reducing accidents.
Step-by-step explanation:
The activities mentioned, including the use of traffic cones, spotters or flaggers, arrow sticks, flashing lights, and warning signs, are all methods employed in traffic management. This is an essential part of road safety that aims to control and direct the flow of traffic, particularly in areas where roadway construction or other potential hazards exist or where there is a need to ensure that vehicles comply with the speed limits. For example, when a traffic signal is installed at a busy intersection, it is primarily to control the flow of traffic and ensure that vehicles adhere to the speed limit, thereby reducing the number of accidents and enhancing the safety of both drivers and pedestrians.
