Route planning software can design efficient routes for businesses with mobile workforces in less than 30 seconds by accounting for traffic, weather, addresses, and other factors. The software allows businesses to avoid busy areas and intersections, automatically check addresses for errors, use electronic signatures for deliveries, design routes that avoid unnecessary left turns and U-turns, track drivers in real-time, and provide analytics to understand business performance. Route4Me is an example of route planning software that provides these features to help businesses improve efficiency.
