Naylor Road Metro Station Area Access and Capacity - WMATA.com.

Crash data, summarized in Table 9 and provided by SHA
as recorded by police reports, reveals that Branch Avenue
experiences more collisions than Naylor Road.
While some of these collisions may be attributed higher
traffic volumes on Branch Avenue, the crash rate (i.e.
typically the number of crashes per million or 100 million
vehicle miles traveled, or VMT) appears comparatively high
to Naylor Road. For year 2008—the only year available for
comparison as AADT data is from 2008 to 2010 and crash
data is from 2006 to 2008—Branch Avenue’s total crash rate
(420 crashes per 100 million VMT) is more than two times
Naylor Road’s rate (201 crashes per 100 million VMT), as

calculated using the Federal Highway Administration’s (FHWA) formula (Appendix 9). Total
collisions dropped on Branch Avenue and Naylor Road between 2006 and 2008, though Branch
Avenue property crashes increased greatly in 2007 before dropping in 2008. In contrast to SHA
ranking Prince George’s County first in Maryland in 2008 traffic fatalities, no roadway fatalities
occurred between 2006 and 2008 near Naylor Road Station.
Kiss & Ride
The Naylor Road Station Kiss & Ride lot includes a taxi stand, 13 A-spaces (15-minute
temporary parking at all times), 42 short-term metered spaces (free 15-minute parking during
peak periods), four Zipcar spaces, four handicap spaces, and 10 motorcycle spaces. During
the afternoon peak period, when the greatest incidence of motorists waiting to pick up rail
passengers typically takes place, 55 temporary parking spaces are available (13 A-spaces and 42
short-term metered spaces). Handicap, motorcycle, and Zipcar spaces, as well as the taxi stand,
are omitted from any analysis of Kiss & Ride capacity, as they are not available to most motorists
picking up passengers.
Field observations conducted during the afternoon peak period at Naylor Road Station in
August 2011 showed that the average dwell time for vehicles in the Kiss & Ride is approximately
2.7 minutes. Rounding this figure up to three minutes and adding a 30-second buffer between
vehicles using the same space yields a capacity of one vehicle per space every 3.5 minutes, or 17
vehicles per hour for each space. Factored by the 55 available spaces, that results in an overall
Kiss & Ride capacity of approximately 935 vehicles per hour. Considering that the station
ridership estimates that the maximum daily Kiss & Ride pickups are approximately 505 (see
Table 4), there is ample capacity to accommodate all users in the Kiss & Ride lot (Figure 32).
Even if all 505 maximum daily pickups occurred in a single hour, the Naylor Road Kiss & Ride
would only require approximately 30 temporary parking spaces to accommodate demand.
Nevertheless, during field observations congestion was observed to be a problem. The
congestion stemmed from motorists waiting for passengers in areas other than marked spaces,
which illustrates that may people picking up passengers prefer to queue rather than pull into
a parking space. This problem is particularly acute in the curved lane immediately adjacent to
the crosswalk closest to the station entrance (Figure 33). Congestion in this spot is particularly
problematic as it can back up to the entrance of the Kiss & Ride lot.
