ROAD DESIGN & INFRASTRUCTURE
The design and infrastructure of roads is important in the safety of driving in a country. It is important to keep different types of traffic separated, provide safe ways for pedestrians and people on bicycles to cross roads, provide safe pavements for pedestrians to walk on, provide clear crossing pathways and signs, as well as speed bumps, traffic lights, and roundabouts to reduce speed in necessary areas where cars are crossing, turning, or parking, and people are walking.
The infrastructures of the roads have to be planned out well due to the different climates in the country. For example, if in one country it rains lot, like in Iran during the winter months, the infrastructure of the roads has to be designed in a way that the roads do not flood. Different climates change does affect the roads, also the gas that leaks from cars affect the road. As far as physics goes, the important factor to consider is speed. The faster a car is going, the more force it needs to be stopped, so in areas where cars might have to stop suddenly or quickly, like in a neighborhood or a business area, it is important that the design and infrastructure of the roads supports the conditions. For example, if there is an areas where cars have to turn right or left a lot to turn into city streets or home areas, then the cars should be going slow, so that when it is time for them to stop, they can do it quickly enough. To make this happen, we need to put speed bumps, traffic lights, and roundabouts in the right places, so that the cars cannot go fast. The government needs to enforce the laws and signs. Like the speed limits, and speed bumps and stop signs, need to be strict, and strict laws should make sure that people do not speed through a stop sign or run a red light. |
Personal StoryOnce, my father's driver was driving, and he did not realize there was a huge hole in front of him on the road, because it was so dark at night, since there were not enough street lights on the road. Half of the car went into the hole. Thankfully, nothing serious happened to the driver, but the car was totaled, we could not have it fixed.
