Dear Dr. Gridlock:

Is there anything we can do to coordinate the traffic lights on Route 5 in Brandywine? In the morning they back up traffic from Waldorf for miles. There are two lights together, and they don't always change at the same time.

It would seem that Prince George's County could improve this situation or create an interchange there like the one in Clinton.

Whom could I contact about this?

Kimberly Grotenrath


You can call the Maryland State Highway Administration for Prince George's County, at 301-513-7300, and ask for traffic operations.

Also, see the related letter from Mr. Francis in today's column.

We all marvel at the Route 5 interchanges built at Allentown and Woodyard roads, closer to the Capital Beltway. Pardon us for clamoring for the same treatment closer to the Charles County line.

Another Rte. 5 Question

Dear Dr. Gridlock:

What happened to the plans to upgrade Route 5's intersections with Surratts, Brandywine and Accokeek roads to overpasses and underpasses? Are there still plans to go ahead with these upgrades?

Darrell Francis

Fort Washington

No small question, with 80,000 vehicles a day passing through those intersections, but the state has not funded interchanges at Surratts, Brandywine and Accokeek roads.

The state did install some turn lanes at Surratts a couple of years ago. A developer is installing more turn lanes, and the state is trying to get the developer not to work during morning rush hours. His work is causing additional inbound traffic congestion, according to Chuck Gischlar, a spokesman for the Maryland State Highway Administration.

Buses Won't Be Stranded

Dear Dr. Gridlock:

Why in the world doesn't Metrobus use a silent alarm that can be triggered by bus drivers? With Global Positioning System technology, such an alarm could alert the Metro police to the location of a bus sending out a distress call.

Chris Miller


Metrobuses do have such alarms, plus a bus's overhead sign can be adjusted to read "Call 911." Metro knows where all of its 1,400-plus buses are at any time because of an automated vehicle locator system that works like the LoJack car recovery system, according to spokeswoman Lisa Farbstein.

One-Plate Mystery

Dear Dr. Gridlock:

The number of Maryland registered vehicles carrying only a rear plate is a widespread problem. I have probably seen a dozen Maryland vehicles each day with only one plate.

I have also seen several vehicles with expired tags, only one registration sticker or no stickers.

Tom Lansford


The Maryland MVA says it is not aware of such problems. I wonder if readers could get more details, such as the license plate number, which plate is missing and where the vehicle was spotted. I can then ask the MVA to look into the matter.

Parking Impasse

Dear Dr. Gridlock:

While driving one-way on 18th Street NW between F and G streets during a recent morning rush hour, I noticed a car parked in the left lane, which is supposed to remain clear during rush hours. Any blockage of these rush-hour lanes can cause severe backups. When I noticed a police officer looking at the car, I thought, "Good! That illegally parked vehicle will be removed."

The next morning, what did I see but the same car parked in the same place, apparently unmoved since the previous morning! The car was not identified as a government or official vehicle, but it was displaying handicap plates.

Now, if it were up to me, I wouldn't even give the president a pass on parking illegally during rush hour. Do you know why this vehicle was allowed to remain in its illegal spot?

Rick Johnson


No, but you can report such chronic problems to the mayor's command center at 202-727-1000. Keep track of your report. If nothing happens in a few weeks, please write back to me, with license plate numbers and vehicle location, and I'll contact the police.

Illegal parking is the single biggest cause of downtown gridlock, and police should be all over violators.

Use Alert Signs More

Dear Dr. Gridlock:

You ask how Maryland officials could make better use of their overhead electronic traffic alert signs [Dr. Gridlock, July 21]. Some years back, I lived in the Netherlands, and the Dutch made extensive and effective use of their overhead signs. Some in-town signs even indicated the optimum speed to travel in order to catch the flow of green lights!

I suggest Maryland learn from the Dutch; it can't hurt to ask.

Don Junior


The optimum speed to catch green lights seems like something we should be interested in. Perhaps some local officials should visit the Netherlands.

Never Too Young

Dear Dr. Gridlock:

Parents need to realize that they start influencing their children's future driving habits when the kids are about 3 years old. Like it or not, children tend to imitate the behavior of those around them. Parents who ferry their kids around are setting an example that no amount of driving instruction can overcome.
