STREET CONFIGURATION
LANE WIDTHS - determining acceptable criteria for safer,
narrow streets
Drivers behave less
aggressively on narrow
streets, running fewer
traffic signals, for
example (Untermann,1990). In studies of
varying street widths
and traffic safety, It
appears that the group
of streets with the
safest results occur
between 22 and 30feet in curb face width.

about 4.6 m (15 ft) and about
7.6 m (25 ft) for arterial streetswith a substantial volume of
turning buses and/or trucks.

BIKE ROUTES - Connections to existing or planned bike
routes including the Towpath and Lakefront trails
Several data sources
have shown that crashes
between motorists and
pedestrians or bicyclists
are less likely when there
are more people out
bicycling or walking
(Jacobsen, 2003).

SHARROWS discussion of Franklin Boulevard application
In San Francisco,
which studied
design and
placement of
sharrows in 2004,
sharrows were
shown to improve
lane positioning of
cyclists and
improved passing
distance by
motorists.
