Urban Freight Case Studies - Washington, DC
DDOT partnered with the Downtown DC and Golden Triangle BIDs and DPW to develop the Downtown Curb-space Management Plan. The Volpe National Transportation Systems Center (Volpe) provided technical assistance in developing the Plan.
The goal of the Downtown Curb-space Management program is to reduce congestion in greater downtown D.C. through five initiatives:6
Reallocation of Curb Space
Regulation of curb-space is a challenging process due to the ever-changing and growing demand for use of limited space. Often, curb-space is not utilized as efficiently as possible, and this produces congestion in adjacent travel lanes.
The Downtown DC and Golden Triangle BIDs compiled information on all curb-space signage for the 14 most highly congested downtown corridors and streets identified by DDOT and Volpe. Based on this information, block- face maps in a Geographical Information Systems (GIS) format were created. DDOT and BID staff also observed and analyzed conditions created by the regulations and developed new curb-space regulatory plans for each block face in the priority corridors. New signage has been installed on K and I Streets NW, between 12th and 21st Streets.
Longer Loading Zones
Developed by DDOT and BID staff, the new regulatory curb-space plans moved commercial loading zones to the approach end of each block wherever possible. This made parking at the curb easier and reduced double parking. The K Street, NW, loading zones also were extended to 100 feet in length wherever possible.
Multispace meters were installed along K Street NW, between 12th and 21st Streets, to better manage curb parking. Several of the benefits of multispace meters include:
In the future, multispace meters have the potential to offer congestion-based pricing or a rate structure that varies by time of day or length of stay.
Metered Loading Zones
DDOT observed a high incidence of commercial vans using loading zones for free all-day parking. In addition, DDOT noted that extended loading times for some delivery vehicles indicated that they should be using off-street loading areas, and the 15-minute limit for vehicles using a loading zone was generally disregarded. To encourage more efficient use of loading zones and vehicle turnover rates, metering of loading zones along K Street, NW, was introduced shortly after the installation of multispace meters. Commercial vehicles must now pay $1 per hour and are limited to two hours.
Enhanced Parking Enforcement
DPW increased its parking enforcement efforts on K Street, NW, between 12th and 21st Street in addition to other curb-space management strategies.
