Many public transit systems have websites where a rider can get information about which bus routes to take. Google Maps also provides transit route directions for users. Additionally, riders can look for transit maps at local bus stations and Visitor's Centers, or ask a bus driver or fellow passenger for advice on which bus routes to take.
Understanding the ins and outs of a city's public transit system takes practice and time, but there are many resources available to help new riders or visitors get around. Online transit route planners sometimes provide directions for slower routes, because the computer programs do not take into account the realities of traffic or riders with mobility issues who need more time to make transfers. Some riders find transit maps cluttered, overwhelming and difficult to read.
A bus driver typically is able to help transit riders with directions but can sometimes be too busy to help someone who is lost. If the transit system has staffed ticket or information booths, a rider can get advice on bus routes at those locations. A rider can usually find an experienced passenger who is familiar with the transit routes and can provide knowledgeable information about the best bus routes to take and the quickest ways to get around.
