Can closing roads improve traffic?


Safety along roads often comes down to reducing motor vehicle speed, or removing them altogether. Opponents of reducing vehicle access often claim increased commute times as a reason not to pursue increased safety measures. However, a phenomenon in network theory known as Braess's Paradox tells us that removing access to a path in a network can sometimes *improve* traffic flow. This project aims to explore how often this occurs in real urban road networks, with the aim of identifying places where safety can be improved without opposition of decreased mobility for car drivers hindering these efforts.
