Chartered buses will be parked at one of four outlying areas -- the Pentagon parking lots, the grounds of East and West Potomac parks and Lots 1, 2 and 3 of RFK Stadium. Shuttle bus service will be operated between the buses and the Mall area for those buses parked at the Pentagon and East and West Potomac parks. Riders whose buses park at RFK Stadium will take the subway to the Mall area. Bus and train riders will pay 50-cents each way for rides. METRO

The subway will operate today from 6 a.m. to midnight -- later if necessary. Trains will run every six minutes on all lines. More frequent service than that is planned after the mass on the Mall, probably around 5:30 p.m.

Metro will not permit patrons to leave the Smithsonian station at the mid-Mall exit because of its closeness to the papal stage and altar and recommends the station be avoided.

Subway riders may use the other Smithsonian exit at 12th Street and Independence Avenue or any of the L'Enfant Plaza exists near 7th and D streets SW, but they'll have to take a long walk to get to the Mall. Police are planning to cordon off an area between Independence Avenue and Jefferson Drive from 4th to 14th Street as a secure "no-Go" zone. Subway patrons coming out of stations adjacent to the zone will have to walk to either 4th or 14th to get around the Mall to the north of Jefferson Drive, where the altar is located.

Metro, therefore, recommends riders walk to the Mall from the Federal Center SW, Federal Triangle, Union Station, Judiciary Square, Gallery Place and Metro Center stations.

The Farecard system for paying train fares will not be used. Passengers will pay a flat 50-cent cash fare for all trips by depositing exact change in screened metal barrels at station entrances. METRO BUSES

Metro buses will run on regular Sunday schedules but extra buses will be added to 68 major routes, beginning at 7 a.m. At least 200 more buses will be used as shuttles to bring in people from outlying parking lots who have come from out of town on chartered buses. Regular off-peak fares will be charged on regular bus routes. Shuttle buses will charge 50-cents each way.

Buses will be added to the following regular Sunday bus routes: 1H, 2A, 3F, 3V, 4G, 6A, 7F, 9B, 11A, 11B, 11E, 16E, 20W, 32, 34, 36,40, 42, 80, 82, 84, 92, 94, A2, A6, D2, D4, G2, G4, G6, H2, H4, H8, J2, J12, J16, K4, K6, £4, N2, N4, P2, Q2, R2, R6, R8, S2, S4, T6, V4, X2, Y6.

Additionally, Metro will operate the following weekday routes that normally lack Sunday service: 5S, 16X, 17A, 18D, 184, 20L, 27G, 29W, 37, A9, C14, K19, £7, £8, M11, R11, R15, T10, T18, T19, W15, Z1. DRIVING

Beginning at 10 a.m. streets will be closed in the Mall area between 3d Street on the east, Independence Avenue on the south, 23d Street on the West and E Street or Pennsylvania Avenue on the north. Police will attempt to keep open the Southeast-Southwest Freeway, 23d Street NW and the three tunnels under the Mall on 3d, 9th and 12th streets NW.

Drivers entering Washington on the 14th Street Bright can expect to be shunted onto the Southwest Freeway. Drivers using Memorial and Roosevelt bridges will be routed north on 23d Street.

There is a possibility that Washington Boulevard, west of the Pentagon, and Memorial Bridge will be closed to autos part of the day, because police are committed to keeping them open for shuttle bus routes at the expense of automobile traffic.

The Shirly Highway express lanes will be open only to express buses until 3 p.m.

After the mass, all southbound 14th Street Bridge traffic will be routed onto the express lanes. The regular southbound lanes will be turned over to pedestrians wishing to hike back to Virginia. Police in both the District and Virginia plan to adjust traffic signals to accommodate outbound vehicles. GASOLINE

D.C. and Maryland energy officials have ordered the major oil companies to deliver more than 1 million gallons of emergency gasoline to Washington area service stations that will stay open during the pope's weekend visit.

In the District, city officials have asked weekend travelers to refrain from driving their cars into the city if possible and to use public transit.

For those who do drive, D.C. energy officials have arranged for 35 stations along major routes to receive 8,000-gallon deliveries of gasoline on the condition that they stay open from 10 a.m. to 6 p.m. Sunday and Monday. Monday is Columbus Day, a holiday.

D.C. Officials also enlisted 21 stations to remain open voluntarily without special gasoline. Maryland energy officials have delivered nearly 1 million gallons to stations on major routes into Washington. Virginia energy officials had no special plans for the weekend. WEATHER

The National Weather Service outlook for today calls for variable cloudiness this morning with a 20 percent chance of light showers. Partial clearing, breezy and cool weather is expected by afternoon. Temperatures should range from 49 to 56 in the morning, and 64 to 68 in the afternoon.Winds will be from southwest at 10 to 15 mph, shifting to the west at 10 to 20 mph by afternoon. PARKING

There will be no parking in the Mall area.

Most downtown Washington parking garages will be open. Some will give preference to their regular contract customers. The lots will charge "established rates," according to the Washington Parking Association.

On-street parking will be permitted in most downtown areas north of Pennsylvania Avenue.

Fringe parking will be provided free at the following locations, but spaces are limited:

In the District of Columbia -- South Capitol Street fringe lot at South Capitol and Firth Sterling Streets SE, and Carter Barron at 16th and Kennedy Streets NW.

In Maryland -- Sears White Oak Shopping Center, New Hampshire Avenue and Lockwood Road; Korvettes, 11800 Rockville Pike, Rockville; Woodward and Lothrop/Geico, Wisconsin and Western avenues, Chevy Chase, George Palmer Highway fringe lot between U.S. 50 and Md. 450 on Palmer Highway; Montgomery County lots near the Silver Spring station.

In Virginia -- Springfield Industrial Park at Backlick Road and Pentagon North Parking.

Shuttle bus or extra regular-route Metrobus service will be operated between the above-listed fringe parking lots to either the Mall or a subway station.

All Metro-operated parking lots at Metro stations will be free. About 12,000 spaces are available at RFK Stadium, near the Stadium-Armory station, for $2. The privately owned Pentagon City station lot will be open and will charge $1.25.
