Beltway Express Lanes wont post travel times
How much time will it save you to use the 495 Express Lanes around the Capital Beltway? Though it might seem a reasonable question for a travel mode designed to save drivers time, the answer wont be available for years, says the Virginia Department of Transportation.
The problem, according to WTOP radio news, is that most GPS systems are only accurate within 30 feet of a location. With the Express Lanes next to the main part of the Beltway, theyre too close to each other for an accurate time estimate for either one individually.
VDOT and Transurban, which constructed the Express Lanes, are also worried that giving too much information to drivers could cause accidents.
Meanwhile, I-66 is adding points with travel times posted: three eastbound and six westbound.
