In the Dr. Gridlock column July 24, a driver complained about the District's new policy to fine people who stop on 14th Street near the Washington Monument to pick up Virginia-bound riders so they can use the express lanes of I-395. This had been a longstanding and popular commuter practice. The penalty for stopping now is $35. In response to the complaint, Chief District Traffic Engineer George Schoene said the city is considering two alternative locations to the 14th Street site: one on 10th Street between Pennsylvania and Constitution avenues NW and a second in the 1400 block of Madison Drive between 14th and 15th streets.

Schoene asked readers for comments and suggestions. Some of those, which also were sent to Dr. Gridlock, follow:

Dear Mr. Schoene:

While I do not believe that the pickup area causes anywhere near the disruption or danger caused by cars blocking the intersection of 14th {Street} and Constitution {Avenue} or by running the lights, I'll concede that traffic flow might be improved by moving the pickup area.

Of the two . . . locations, the most logical and convenient would be the 1400 block of Madison Drive. This would allow drivers to continue to use the 14th Street corridor and to take advantage of the left turn allowed at 15th Street. Traffic is less heavy on Madison Drive and the distance the riders would have to walk to be picked up is similar to the current distance.

The other . . . location is far less convenient because that block is often filled with {Metro and tourist} buses. The only easy access to the express lane would be through the Ninth Street tunnel and that is farther out of the way for the drivers, as is 10th Street.

Whichever location is chosen, I would hope for fair warning. Having the D.C. police ticket drivers now with no alternative . . . is precipitous and unfair. DAVID G. PAYNTER Springfield Dear Mr. Schoene:

I urge you to help commuters like myself keep the system that serves us and the city so well. At present, I can get home in 35 minutes. Should the car pool be abolished, I would have to take a bus and the Metro at a cost of about $1,000 a year ($4.20 {per} day; $21 {per} week). For a single parent like myself, this represents a considerable savings of time and money.

I would prefer the new location at 10th and Pennsylvania. However, I would also like to go on the record as saying I would go almost anywhere in the 14th Street area to pick up the car pool.

I hope you will be able to help the hundreds of people like myself who rely on this fast, convenient and cheap transportation daily. DONA DE SANCTIS Springfield Dear Mr. Schoene:

I have been a rider and a driver for the past five years and if, in fact, the situation has been thoroughly researched by an intelligent individual or team, it would be immediately clear that the brief stops {to pick up riders} don't begin to compare to the length of time the Metrobuses stop.

Isn't that what is really the problem here? Isn't it that Metro is complaining about all that lost revenue? Why does everyone in Washington refuse to see the benefit to the District, in terms of thousands {fewer} autos coming into the already nightmarish road system? A drive anywhere from the 14th Street bridge to K Street, the Capitol to the River, is nothing but one big obstacle course of blocked lanes and busted asphalt.

But back to the 14th Street/Constitution Avenue pickup spot . . . . The alternates suggested will not work because the drivers will have to go through so many more turns and hassles to get over to them and back {to} the express lanes that they won't have saved themselves any time. Who is this supposed to help?

All it would take is a change in the sign at that particular spot to read Car-Pool Pickup, One Minute {or 30-second} Limit. As long as right turns are allowed onto Constitution Avenue at 14th Street, the present pickup spot doesn't hurt anyone but it helps thousands. ALICE M. TAYLOR Springfield Dear Mr. Schoene:

I understand the "No Standing" provisions on 14th Street NW, for I continually become frustrated when encountering drivers sitting and waiting for a passenger.

{But} I have great difficulty with the "No Stopping" provision. To me, it is a minor inconvenience in trade for fewer automobiles funneling in and out of the city . . . a compromise I am willing to make, just as I make the compromises necessary to be in a car pool.

Since the river and the bridges are in your jurisdiction, it seems that moving fewer cars over the upstream and downstream spans would be a fair trade for allowing "stopping" but not "standing." I believe a distinction may be drawn between "stopping" and "standing," and most jurisdictions apparently agree or the signs would not read as they do.

Moving from the rational to the emotional, it just plain {angers me} that a cab or bus can stop at the curb to pick up a waiting passenger and I cannot. Just how am I supposed to get to 10th Street, which is hardly on the way to anywhere? Madison Drive?

Look, it would be nice if you didn't have to put up with non-District traffic and the rest of the District's services didn't have to provide support to nonresidents. I'm certain it would be just as nice if Virginia didn't have Maryland traffic and vice versa. Unfortunately, that's the way it is.

Cut me a break . . . fine me if I stand out, but for crying out loud, allow me to pick up a waiting passenger at the curb. DAVID M. CROYLE Manassas Sir:

I am writing to . . . support the location of 1400 Madison Dr. as the pickup spot for the Springfield Underground. This location is more agreeable to the majority of riders, I suspect, because it is closer to the 14th Street spot we are used to. Also, it is more a central location than the 10th Street location because many of us walk over from the Northwest area around 18th and K.

The Madison Drive spot was used for a few days earlier, but without any enforcement, drivers continued to stop at the 14th and Constitution spot whenever they saw riders they recognized, and vice versa. Then those of us who were waiting over on Madison were left standing "carless."

I understand your wanting to open up 14th Street traffic, and as long as you are concentrating on south of Constitution, you might look north of Constitution and ticket the husbands who wait for their wives to come out of {the Department of} Commerce, blocking one lane of 14th Street. That has been the case since I started working downtown 10 years ago, and is the case outside most government office buildings. It's true on 15th {Street} in front of the Treasury, too.

Please help to maintain one of the few systems I know of that works in the District of Columbia. PATRICIA PRICE Springfield

Schoene plans to meet soon with D.C. police officials to share the letters with them and discuss the current "No Stopping, No Standing" policy as well as alternative pickup spots, according to D.C. Department of Public Works spokeswoman Tara Hamilton.

Schoene was unavailable this week, but Hamilton said his staff has been receiving the letters and plans to respond to each one. But, she said, no decision will be made solely by the Department of Public Works.

"Obviously, we want to do this in cooperation with the Metropolitan Police Department," she said. "One of the considerations {given as alternatives} was what would cause the least disruption to traffic."

Meanwhile, D.C. police spokesman Quintin Peterson said the department's "enhanced rush-hour traffic enforcement," which began March 30, is still in effect. There is still a $35 fine for violating the "No Stopping, No Standing" rule.

Peterson repeated parts of a harshly worded statement released when the policy was announced.

"The goal of the plan is to reduce traffic congestion by eliminating the obstacles that adversely affect the morning and afternoon rush-hour periods . . . . Unfortunately, enforcement procedures must be used in dealing with nonconformists who persist in using improper driving practices . . . . The tolerance of the community has been seriously strained by a few motorists who disregard the traffic laws and display a lack of concern for others."

Peterson said that with more than 280,000 registered vehicles in the District combined with the number of cars from Maryland and Virginia, all using the 1,100 miles of city streets, an aggressive traffic enforcement plan is essential.
