Restriping Washington Boulevard Might Induce More Crashes

Comments at Arlington County Board Meeting on March 18, 2016.

Arlington County Transportation Division plans to ask VDOT to restripe Washington Blvd. between EFC and Westover as part of a repaving project.

Program Manager David Goodman described the project and conducted a Q&A at a March 1 meeting he hosted at Westover Library. In response to a subsequent email soliciting public comment, I sent Goodman the following questions, which I want to share with you. (more…)

Widening I-66 Eastbound Inside the Beltway: Is it Really Needed?

Comments at December 5, 2016 VDOT Public Hearing on Environmental Assessment (EA) for Widening Eastbound I-66 Inside the Beltway.

The fact that Arlington residents have an opportunity to comment tonight on the environmental assessment for widening I-66 eastbound is a step in the right direction. When VDOT widened the same stretch of I-66 westbound in 2010, there was no EA public hearing, because there was no EA. (more…)

PRESS RELEASE: I-395 HOT Lanes Extension: An Accident Waiting to Happen

The I-395 Express Lanes North Extension Environmental Assessment (EA) lists roadway safety as one of four principal objectives in extending I-395 toll lanes north to Eads Street (p. 6). It cites the fact that over half of all roadway crashes occur during peak travel periods to demonstrate that congestion not only increases travel time, it also jeopardizes traffic safety (p.14). 

VDOT’s concern with roadway safety is well placed. However, it is by no means clear that HOT lanes will enhance travel safety even if they reduce congestion, since the Build Alternative all but eliminates the western shoulder of the express lane corridor by reducing it from 10 feet to 2. (more…)

Comments to NVTC on Widening I-66 Inside the Beltway

Comments to Northern Virginia Transportation Commission  (NVTC) on Widening I-66 Inside the Beltway on May 5, 2016.

First I want to express my regret that a deal worked out between NVTC and Governor McAuliffe last year to toll I-66 inside the Beltway first and widen it later only if necessary was scuttled in favor a plan to widen I-66 as soon as the tolls are in place. (more…)

VDOT Put the Cart Before the Horse Heading Westbound on I-66 in the A.M.

On October 2, 2015 months after Virginia Department of Transportation (VDOT) announced its decision to toll I-66 inside the Beltway, it published the results of a modeling study entitled: “I66 Multimodal Improvements: Future Conditions Traffic Technical Memorandum”, which assesses the impacts of tolling on I-66 and parallel arteries.

Based on the Metropolitan Washington Council of Governments (MWCOG) TDM Version 2.3, Build 57 regional model, the report indicates that while traffic volume in the a.m. and p.m. peak [traditional] direction will not change much either on I-66 or parallel arteries, non-peak [reverse commute] direction traffic will divert onto parallel roadways. Traffic operations at key locations along Routes 50 and 29 will be degraded as a result. (more…)

VDOT Must Sway Opponents of Tolling I-66

I’m persuaded that Virginia Department of Transportation (VDOT) is genuinely interested in addressing concerns about the traffic impact of tolling I-66, which I support. Nevertheless I’m concerned that VDOT has not responded effectively to the concerns raised. For example, Delegate Jim LeMunyon recently trashed VDOT’s plans to toll I-66 inside the Beltway. (more…)

Keep the Bus and Toll the Road

I am delighted at VDOT’s decision to toll I-66 inside the Beltway and to investigate the impact of tolling and other Transportation Demand Management (TDM) measures to mitigate congestion before undertaking any further widening of the roadway. This makes good sense from both a traffic engineering and financial standpoint. If improved mass transit options together with tolling reduce congestion what’s the point of spending millions of dollars that VDOT could use better elsewhere in Northern Virginia?

Silver Line Alternative to Parking on I-66

Last December during morning rush hour I shuttled with my bike from the Wiehle Reston Metro Station to Herndon Park and Ride, where I then boarded a standing room only 5A bus to L’Enfant Plaza.

I commented to the 5A bus driver that he must be very popular with commuters to attract such a crowd. No, retorted an irate middle aged passenger. She said it takes more than an hour to get into town via the slow moving Silver Line, whereas it takes only 45 minutes via the 5A bus, which stops at Rosslyn Metro en route to L’Enfant Plaza.
