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.

STREET CONFIGURATION

CURB RADII improving pedestrian safety whileaccommodating emergency vehicles

In new construction, the

appropriate turning radius is

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.

DESIGN FOR BICYCLES

Lakefront Bikeway,

Cleveland

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).

DESIGN FOR BICYCLES

Pittsburgh

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.

SPEED LIMITS USGBC requirements for dedicated bike

routes

Fatality rate of

vehicle/pedestrian

accidents dropsfrom 45% at 30

mph to 5% at 20

mph or less (U.K.

Department of

Transport, 1997)
