The Capital Beltway is 64 miles of roadway surrounding Washington,
D.C. The Capital Beltway Safety Team, led by officials from Maryland
and Virginia, was formed to address safety issues on this urban interstate
highway. This report documents the results of focus groups run during
May, 1997 for the Safety Team. Of the eight groups conducted: three
were composed of representative Beltway drivers of private passenger
vehicles; two were composed of specifically selected "aggressive
drivers;" and three were composed of commercial truck drivers.
Procedures followed those used in 1994 for a similar study. The results
indicated that roadway design and maintenance issues were of less
concern to focus group participants in 1997 as compared with 1994
likely reflecting Beltway improvements made during the last three
years. Unsafe driving actions, including aggressive driving, were
of more concern. Focus group participants supported information, education,
licensing and congestion reduction countermeasures. They also supported
vigorous law enforcement of traffic laws even knowing that law enforcement
presence would add to traffic congestion.
