13.9.2 Suburban Design
Pedestrian activity on suburban roadways tends to be in the range of light to moderate. The following recommendations address the presence of pedestrians and facilitate potential future retrofits without heavily impacting mobility.
Angle of Entry -
See guidance provided under
.Curb Radii and Curb-to-Curb (Throat) Width -
The radii and throat width for right-turning roadways in suburban areas should be designed to accommodate larger vehicles. In the event that the area becomes more urbanized in the future, the turning roadway can be striped to delineate a tighter radius, promoting lower speeds and improving visibility of pedestrians for motorists (see
and
). See Cross Sectional Elements in
for striped lane width.Channelizing Island -

.Deceleration Lane -
See guidance provided under
.Acceleration Lane -
Acceleration lanes may be used; however, they make it more difficult for pedestrians, especially those with visual impairments, to cross the turning roadway. Therefore, acceleration lanes are not advisable where pedestrian activity is anticipated.Drainage -
See guidance provided under
. When pedestrian facilities are not initially installed, consideration should be given to determine where crosswalks may be installed in the future to avoid conflicts with inlet locations.Lighting -
See guidance provided under
.Apparatus and Pole Placement -
See guidance provided under
. When pedestrian facilities are not initially installed, care should be taken when placing ITS equipment, apparatuses, and signal and utility poles to avoid the anticipated or planned location of future pedestrian walkways and landing areas.Crosswalk Location -
See guidance provided under
. If an acceleration lane is present, consider placing the crosswalk at the upstream end of the turning roadway, placing pedestrians in the line of sight for drivers as they decelerate to make the turn. At the downstream end, on approach to an acceleration lane, drivers will be accelerating out of the turn and more likely focusing on cross-street traffic.Crosswalk Orientation -
