Getting around Blacksburg by car has gotten more difficult as the years go by. Yes, there are more cars on the streets (it seems the students all arrive in the fall with two cars each). But the town itself has added to the problem with physical changes and legal restrictions.
First, the legal. The town placed stop signs on Draper Road between Miller Street and Airport Road to control the speed of vehicles avoiding traffic on Main Street. This was despite what the bible for traffic engineers states "STOP signs should not be used for speed control." (the Manual on Uniform Traffic Control Devices, or MUTCD defines the standards used by road managers nationwide to install and maintain traffic control devices on all streets and highways. The MUTCD is published by the Federal Highway Administration. See http://mutcd.fhwa.dot.gov/htm/2003r1r2/part2/part2b1.htm#section2B04).
Other stop signs have cropped up around town, most recently on Airport Road at Country Club Drive and at Southgate Drive. It would be interesting to see the engineering studies that have determined that these stop signs are needed due to high volumes of traffic and were not placed to appease neighborhood residents.
Other legal restrictions imposed by the town are the setting and posting of speed limits at artificially low numbers, especially given the street conditions. The town seems to feel that if the speed limit is set lower, then traffic will actually travel at an appropriate speed. For example, the speed limit on Patrick Henry Drive between Main Street and Toms Creek Road was 35 MPH.
Most traffic traveled at 35-40 MPH, while others speed along at 45 MPH or higher. About a year ago, the speed limit was lowered to 25 MPH. A lot of the traffic still moves at about 35 MPH, but that makes everyone going that speed a law violator (and when the students are gone, the police are out running radar to catch those miscreants). Given that this is a wide, four-lane street designed to move traffic, it is difficult to travel at 25 MPH.
There are other streets in town where the speed limit has been dropped to control speed, even though the MUTCD states "After an engineering study has been made in accordance with established traffic engineering practices, the Speed Limit sign shall display the limit established by law, ordinance, regulation, or as adopted by the authorized agency." (see http://mutcd.fhwa.dot.gov/htm/2003r1r2/part2/part2b1.htm#section2B13). Again, it would be interesting to see the reports done by the town after these studies.
The town has also put in place physical changes to slow or restrict traffic on town streets. Traffic islands were built at both ends (Airport and Miller) of Draper Rd. and Preston Ave. to restrict traffic entering those streets. More recently, "traffic calming" devices, curbing impinging into the lane of travel, have been added. The same type of curbing has been added to what has for years been a major thoroughfare, Southgate Drive. Because these devices narrow the street, they force drivers to slow down. While this may promote safety, it limits the amount of traffic that can travel down a street in a given amount of time.
The latest (and expensive) project is to eliminate Broce Drive as a convenient route to get between University City Blvd., Toms Creek Road, Progress Street, and points beyond. This has always been a more direct route than taking UCB with its longer distance and nasty S curves. But the people in that neighborhood (including a town council member) don't like traffic. First, speed humps were installed (same as the ones on Grissom Lane to slow through traffic), but drivers slow for them, then speed to the next one. Now, the street is being narrowed with the addition of curbs and a sidewalk, plus a roundabout at Lora Lane.
While protecting neighborhoods is laudable, the town has also been inconsistent in its actions. Despite protests from residents in the Shenandoah subdivision, the town pushed to connect Progress Street from its end in that neighborhood to its continuation in a large subdivision off Givens Lane.
The town and VDOT also put forth plans to convert that same Givens Lane from a two-lane street into a major four-lane (with sidewalks and bike lanes) throughway -- serving what? It would make more sense to take that construction money and invest it in improving and synchronizing the traffic lights and other projects (like the new turn lanes at various Prices Fork Rd. intersections) that make traffic flow better (so people don't have to use those neighborhood shortcuts). The town could also spend more time going after those who greatly exceed speed limits instead of setting artificially low speeds that sets up many drivers for a potential ticket.
