Road traffic control entails the direction of pedestrian as well as vehicular traffic around disruptions on the road, accidents and construction zones that will help ensure the safety of workers as well as the general public. Traffic controllers are called to intersections and those roads that are suffering from a traffic jam or any other disruption so that they can restart the flow of traffic. They are also stationed near schools to help pupils cross the road safely. Traffic is also monitored through cameras so that the authorities know if anyone is breaking the law or disrupting it and proper action can be taken. The traffic controllers have an occupation that needs them to be outdoors in all types of weather and at day or night for long hours. Whether it be under the sun or in the snow. They also are at high risk of being struck by passing vehicles that may be speeding or the drivers may not be paying attention to where they are going.  Construction sites are hazardous sites and those that are near roads need to have proper warning signs so that people that are driving or walking by know that they need to be careful while going through that area. The worksite may also close part of the road if they consider it too dangerous to allow people to go by it especially if there are cranes nearby that are lifting and transporting heavy materials. If there is an accident on the road or the road is being repaired then part of the road is closed off and traffic is diverted to safer routes. Go here for more information about traffic management. 

Traffic signals are an important part of better traffic control as these are devices that allow for best control at different road intersections. The help tell the driver of what they should and should not do. The biggest function that they perform is to assign the correct way to the opposite flow of traffic so that there are no clashes. The traffic signals are very easy to understand and children learn their meaning at a very early age as well. Sometimes, however traffic signals may actually interrupt a heavy flow of traffic to allow minor flow from the other side, this is where traffic controllers can step in to allow the heavy flow to run itself out.  The whole traffic management system is linked to control centers that collect and process the data on traffic and then find ways to better control and guide it. Traffic management also helps the pedestrians by informing them when it is safe to cross a road and in turn prevents accidents from occurring.
