As population and jobs have become less concentrated, providing transit services to Maryland residents has become increasingly challenging. Nearly three-quarters of all workers in Maryland drive alone to work. And, though transit services are available to many (almost 80 percent of the state's population live within a 10-minute drive of a commuter service such as the Maryland Transit Administration's MARC train and commuter bus services), development patterns make it difficult to take transit to non-work destinations, such as shopping and recreation.
