 Road traffic congestion costs South Africa over one billion rand annually. The city of Johannesburg is ranked 77th in the world for traffic congestion. Causes of increased traffic include urban migration, affluence, underdeveloped public transport systems, power cuts and malfunctioning traffic lights. This is made worse by copper cable theft, road closures and damaged roads. In many cases it is difficult to expand the road network. Fortunately, an efficient and more affordable solution that can improve traffic flow is to deploy traffic pointsmen. By developing a model that fuses crowdsourced data on traffic congestion from social media with real-time traffic data, we can recommend the best locations for traffic pointsmen to be deployed to. The system is robust to unreliable traffic infrastructure and optimises the distribution of traffic pointsmen to ease congestion.
