Blake Lane Corridor Safety Updates

Latest News 

On August 2022, with the help of School Board Member Karl Frisch and Fairfax County Public Schools, 22 bus stop locations were adjusted to eliminate the need for students to stand and wait on Blake Lane.

On August 2^nd, the Board approved the installation of “Watch for Children” Signs and “$200 Additional Fine for Speeding” Signs as part of the Residential Traffic Administration Program on Blake Lane. In the July 19^th Board Meeting, I presented a Board Matter with Chairman McKay and Supervisor Alcorn, which directed staff to provide information and recommendations on purchasing additional speed devices so that we have more capacity countywide to use these effective deterrents to speed.

Beginning early June 2022, the Fairfax County Police have increased police patrol presence along the corridor and have deployed a radar speed sign at the site.

On May 18, 2021, the Board of Supervisors approved the resolution for the installment of "$200 Additional Fine for Speeding" signs on Blake Lane, between Jermantown Road and Sutton Road, as part of the Residential Traffic Administration Program (RTAP).

On September 2021, the requested "$200 Additional Fine for Speeding" signs have been installed on Blake Lane.

On November 2021, the Virginia Department of Transportation (VDOT) conducted a signal warrant study at Blake Lane and Hibbard Street, collecting traffic data to be evaluated by a traffic engineer. It will be several months before it is known whether the intersection meets required warrants.

Due to residents' requests, VDOT installed a speed radar to determine the appropriate speed in this corridor and the 85th percentile was 43.5 MPH. VDOT says the current speed limit of 35 MPH is appropriate for this road. The 85th percentile speed is defined as, "the speed at or below which 85 percent of all vehicles are observed to travel under free-flowing conditions past a monitored point." Another way to consider this is the speed at which 15% of traffic violate on average.
