SCENARIO BSCENARIO A
CROSS TRAFFIC
DOES NOT STOP
Intersection Crossing: Stop Sign ControlA
APPLICATION
CONSIDERATIONS• At two-way stop, stop sign should be placed on
the lower-volume street
• Stop signs should not be used as speed control or
traffic calming
• May be supplemented with “Stop Ahead” signage
• Crash history
• Observed conflicts
• Limited visibility on one or more approaches

NAPERVILLE - 5TH AVENUE REDEVELOPMENT
Midblock Crossing: Standard TreatmentB
APPLICATION
CONSIDERATIONS• Difficult to use safely for pedestrians with visual
impairments (unable to determine gap in traffic
or stopped traffic) compared to a stop condition
• Multi-lane crossings should provide a median or
refuge island
• Review pedestrian visibility (e.g., onstreet
parking, lighting)
• Provide advance crosswalk warning signs for
vehicle traffic
• Facilitate crossings where there is consistent
pedestrian demand
• Create a direct route to key destinations
• Locate away from nearest side street or driveway
so that drivers turning onto the primary street
notice pedestrians

CONSIDERATIONS
Mid-Block Crossing: Increased Signage
SIDEWALK
• Difficult to use safely for pedestrians with visual
impairments (unable to determine gap in traffic
or stopped traffic) compared to a stop condition
• Multi-lane crossings should provide a median or
refuge island
• Review pedestrian visibility (e.g., onstreet
parking, lighting)
• Facilitate crossings where there is consistent
pedestrian demand
• Create a direct route to key destinations
• Locate away from nearest side street or driveway
so that drivers turning onto the primary street
notice pedestrians
• Encourage motorist compliance

APPLICATION
CONSIDERATIONS
Mid-Block Crossing: Curb Extensions
SIDEWALK
NOT TO SC ALE
• Difficult to use safely for pedestrians with visual
impairments (unable to determine gap in traffic
or stopped traffic) compared to a stop condition
• Must be designed to accommodate drainage
• May require fire hydrant relocation
• Enhance visibility of pedestrians
• Reduce crossing distance
• Facilitate crossings where there is consistent
pedestrian demand
• Create gateway to lower speed area
• Reduce speed of turning vehicles

APPLICATION
CONSIDERATIONS
Mid-Block Crossing: Speed Table
NOT TO SC ALE
MA X. 50’
SIDEWALK
• Difficult to use safely for pedestrians with visual
impairments (unable to determine gap in traffic
or stopped traffic) compared to a stop condition
• Use of distinctive materials may require additional
maintenance but highlight and define the speed
table
• Typically preferred by emergency response over
speed humps
• Existing City of Naperville policy prohibits speed
tables and speed humps
• Enhance visibility of pedestrians
• Traffic calming device
• Create gateway to lower speed area

APPLICATION
CONSIDERATIONS
Mid-Block Crossing: Rectangular Rapid Flashing Beacon
NOT TO SC ALE
SIDEWALK
• Requires FHWA permission for use
• Regular use of RRFBs could decrease effectiveness;
should be used at key uncontrolled intersections
only
• To minimize glare during nighttime conditions, an
automatic signal dimming device should be used
• Increase driver yielding rates to pedestrians
• Lower cost alternative to traffic signal

APPLICATION
CONSIDERATIONS
Mid-Block Crossing: In-Pavement Lighting
SIDEWALK
• Difficult to use safely for pedestrians with visual
impairments (unable to determine gap in traffic
or stopped traffic) compared to a stop condition
• Actuated by pedestrian, lights may be
misinterpreted as control device
• Encourage motorist compliance
• Enhance visibility of crosswalk

CONSIDERATIONS
Railroad Crossing: Re-Open Cow TunnelA
• Potential for significant utility conflicts and
unknown risks
• ADA access (e.g., elevator or ramp)
• Stormwater drainage
• Amtrak, BNSF, and Metra coordination required
for shutdowns during construction
• Amtrak/BNSF/Metra service disruptions during
construction (could require 48- to 72-hour
shutdown)
• Security concerns associated with a tunnel (e.g.,
limited visibility)
• High-level review suggests the structural
integrity of the cow tunnel may require repairs
• Cost to modernize and repurpose to current code
could exceed cost of a new underpass
• Available right-of-way limitations

B Railroad Crossing: Construct New Underpass
CONSIDERATIONS• Security concerns associated with a tunnel (e.g.,
limited visibility)
• ADA access (e.g., elevator or ramp)
• Stormwater drainage
• Amtrak, BNSF, and Metra coordination required
for shutdowns during construction
• Amtrak/BNSF/Metra service disruptions during
construction (could require 48- to 72-hour

PEDESTRIAN SAFETY & CONNECTIVITY: RAIL CROSSING TREATMENTS
COST ESTIMATE: $3-5 million• Structure is not temperature controlled except at
elevators (if provided in lieu of ramps)
• Considers precast box culverts
• Assumes 10 foot clear dimension inside of the
tunnel.
• Excludes site civil and utilities
NAPERVILLE - 5TH AVENUE REDEVELOPMENT
C Railroad Crossing: Construct New Pedestrian Overpass / Skyway
• Create sense of security and desired level of service
• Opportunity to integrate with development or parking deck
• Site impacts and coordination with BNSF, Metra, and Amtrak for closures
during construction
• ADA access (e.g., elevator or ramp)
• Aesthetics and height
• Maintain conductor line of sight to signal stations
PEDESTRIAN SAFETY & CONNECTIVITY: RAIL CROSSING TREATMENTS
CONSIDERATIONS
COST ESTIMATE: $2.5-4 million• Structure is not temperature controlled except at elevators
• Assumes a pre-engineered steel truss; minimal architectural features
• 70-foot span and 12-foot wide truss
• Includes hydraulic elevator at each headhouse
• Reflects headhouse elevation to allowed for the required clear height
between top of rail and bottom of bridge structure
• Excludes site civil and utilities
