Louis Knapp {letters, Nov. 27} is on target in saying that the Washington area needs market-oriented solutions to its traffic problems and that more parking spaces are needed near Metro stations. However, that is not the whole answer.

Mr. Knapp said that the Council of Governments should not recommend taxing employer-paid parking. Maybe not. But something should be done to encourage employers to subsidize subway fares, not just parking in lots. If employers offered workers Farecards, or a transportation allowance, more people might use the subway.

I have been a rider of the Silver Spring Metro since its maiden voyage on Feb. 6, 1978 -- it's not cheap, but it's cheaper than parking downtown. Mr. Knapp said he lives two miles from a Metro stop. Why couldn't he arrange with a member of his family or someone in his neighborhood to drop him off at the station? For someone who lives so close to the subway, that would be an obvious solution.

Mr. Knapp also commented, "A reasonably affluent citizenry simply won't allow itself to be forced into buses." I'm not sure what his definition of "reasonably affluent" is. Although my income is well below the Montgomery County median, I certainly would not call myself poor. Yet driving into town has never been an option I could consider because paying for my own parking is prohibitively expensive.

I don't know if Mr. Knapp was referring to a bus trip all the way into town (13 to 15 miles from his Rockville home) or just the two miles from his house to the nearest Metro. Surely he could manage two miles? I travel almost seven miles from the fringes of Rockville to the Metro each day on the bus, and I know it can be done. But if one is looking for door-to-door convenience, Metro will never be the answer. Some trade-offs must always be made.
