In response to The Post's editorial "Regional Movers and Shakers" {July 21}, the creation of a Northern Virginia Regional Transportation Authority is not the answer to Washington's gridlocks.

Currently we have the Virginia Transportation Commission, the Northern Virginia Planning Commission, the Virginia Department of Transportation and the Northern Virginia Planning District Commission, not to mention the Washington Metropolitan Area Transit Authority. We need another organization like we need more traffic.

I believe what John Herrity had in mind when he proposed this authority was a monorail from Richmond. We already have a railroad to Richmond.

Recently the Virginia General Assembly empowered the Commission on Transportation for the 21st Century to examine the structure of the Virginia Department of Transportation, county government and related District commissions and make improvements to facilitate delivery of transportation services in the Commonwealth. This is a step in the right direction -- by the right people.

Recommendations on the situation in Fairfax County have recently been published in the "Report of the Citizens Committee for the Review of Land Use and Transportation Planning in Fairfax County," an effort initiated by the League of Women Voters. It was enlightening and rewarding to be part of this group of citizens examining the way county government works and does not work. The committee's comprehensive and readable report will be available at local libraries. Perhaps I could send a copy to The Post, as it seems it has not seen this interesting and fact-filled publication.

What we need in Virginia and surrounding counties is more cooperation and action by the organizations that already exist. For example, a commuter rail from Burke to Union Station that would use existing rails makes sense. Two years ago Audrey Moore started working on this good idea. However, the District does not seem to want such a commuter rail.

I am relatively new to this area, but it does not take long to see that there is a traffic problem. One of the first steps in the right direction would be to get a commuter rail going. How about it, District of Columbia?
