As an analyst of the intercity bus industry for the National Academy of Sciences' Trnasportation Research Board, I was disappointed that the Outlook article "Greyhound Blacktop Blues" {June 24} did not begin to address key questions about the need for and survival of this mode of transportation. The article did highlight two important facts -- that many bus riders have low incomes and few alternatives to the bus and that the buses are packed, i.e. there is a market for intercity bus transportation.

Unfortunately, the article didn't mention that many people traveling to and from rural areas may lose bus transportation as Greyhound has not reinstated all of its pre-strike services. Nor did it mention that the level of service to cities may also be affected by Greyhound's labor problems and its bankruptcy filing.

National transportation policy does not acknowledge the role of intercity buses in meeting the transportation needs of a large segment of our population. That policy calls for a "market" solution for the problems of this industry, even as more prosperous air and rail passengers receive federal subsidies and support. One would think that an intercity carrier that services some 9,500 places -- and serves those with few transportation alternatives -- would receive more attention from Congress, the administration and the media as it battles for survival.
