Traffic rerouting is the process of changing the path that vehicles take to avoid congestion, accidents, or road closures. This can be done manually by traffic control personnel or automatically through navigation systems like GPS apps. The goal is to improve traffic flow and reduce travel time for drivers. When a road is blocked or heavily congested, rerouting helps direct vehicles to alternative routes. This can involve using side streets or highways that are less crowded. Rerouting is essential for maintaining safety and efficiency on the roads, especially during peak travel times or emergencies.
