HopStop and Google maps both offer subway directions in many locations. Individual transit systems such as the New York City Metropolitan Transit Authority and the San Francsico Bay Metropolitan Commission offer directions for their local systems through a trip planner tool.
Hopstop, Google and local transit system websites all offer their services free to riders and include the ability for users to enter a start and end point and receive transit directions on select transit systems. Fare information is provided by all sites, but local agencies display more details about the purchase and use of fare cards.
HopStop allows users to find local subway stops, send directions by email, plan a transit trip with multiple destinations and calculate estimates for calories burned and carbon emissions savings for a route. Google Maps offers accessibility features for the seeing impaired, includes multiple languages and links to transit agency websites. Both sites include mobile device integrations and stop and schedule information.
Local agencies display real-time transit updates in the form of maps, service statuses, videos and social media postings. While public transit-focused sites such as HopStop display taxi costs for subway riders to compare to public transit, San Francisco and New York's transit sites publish information on carpools, parking and ridesharing. Local agencies also provide detailed information to riders through stories regarding long-term construction projects, contact numbers and breaking news.
