Decades ago, the number of private cars was small, and there were not many public transport vehicles. Traffic congestion was not a problem; but as the population continued to increase and the city concentrated, traffic problems worsened. According to reports, traffic jams not only make travellers frustrated, but also waste valuable time; the time spent on traffic jams is up to billions of hours every year, regardless of public or private companies, they want to find a solution.
Roads in central Uganda, Africa, are already full of cars, mainly because of the significant increase in the number of cars in cities in recent years. According to population projections, 60% of the world's population will live in the city by 2030; as more and more people enter the middle class, the demand for cars will continue to grow.
Despite the government’s efforts to build traffic signs and deploy traffic police, traffic problems remain difficult. Is it because of the road surface problem? Still too few roads? This is a very complicated issue. At the moment, there are some ideas in the making, but no one can guarantee that these methods will work. Technology needs to be integrated into existing infrastructure, but there are still many issues to be overcome.
At present, the industry has tried to use artificial intelligence (AI) to respond to road conditions in real time. Such intelligent traffic signs have been proven to work in some places. It is pointed out that the intelligent traffic sign can shorten the traffic time by 25%, reduce the brakes by 30%, and idle at 40%. If you install it on the busiest traffic, it may help improve road conditions.
Each traffic sign can decide to turn red or green. First, there is a computer at each intersection that is equipped with a surveillance camera or radar. Each intersection can monitor the road conditions in real time, establish a time plan, and calculate how much green time each intersection needs, thereby improving efficiency.
When an intersection is analyzed, it communicates with the surrounding intersections to establish an integrated network behavior. Of course, this can be a very expensive investment, so it should be imported from the main main road with the largest traffic flow.
