Anyone who has ridden NYC's subway system knows it's a remarkable example of engineering and transport, if not for the sheer volume of daily riders. You'll also know that delays are frequent and service outages are just as common (weekends on the G train anyone?). Still, the city is aiming to improve user experience with the newly released touchscreen maps, which hit Grand Central Station this week. Users are given up-to-the-minute updates on underground closures, delays and directions. Though aimed largely at tourists who are unfamiliar with the system, regular riders will also benefit when traveling off their beaten path or in the (likely) event of alternative service routes.
