The City of San Antonio's goal is to improve mobility safety across all modes of travel in a way
that fits the neighborhood environment through retrofitting residential streets with
"traffic
calming" features and other devices and treatments.
"Traffic Calming" refers to modifying streets in such a manner as to reduce the negative effects
of cut-through and/or high speed traffic while enhancing the safety for pedestrians and bicyclists
alike. Such efforts are typically aimed at reducing vehicle speeds and/or the volume of non-local
traffic in residential areas.
Various treatments can be applied to address specific problems. Speeding problems can be addressed
by changing vertical alignment or horizontal alignments. Speed humps, traffic circles, median
islands, and chokers may effectively reduce operating speeds. Cut-through traffic problems can be
addressed by blocking certain movements that divert traffic to streets designed to handle the higher
volumes. Street closures and diverters may help reduce or eliminate cut-through traffic. Visual
Obstructions can be addressed by extending curbs in certain areas to provide better visibility while
also slowing through speeds.
Traffic calming features are only appropriate on two-lane, residential
"local" and "collector"
streets. With the exception of median barriers, traffic calming features may not be used on major
arterials as designated in the Major Thoroughfare Plan.
Speed Humps
Speed humps have been the "canned" solution for traffic calming in San Antonio for some time.
The City of San Antonio and many other communities have determined that speed humps are an
effective and appropriate roadway feature for safely reducing vehicle speeds on certain types of
streets. The usual installation provides two speed humps that are a few hundred feet apart,
thereby creating a zone in which vehicle operating speeds are in an acceptable range.
Emergency Services:
Because speed humps have a negative effect on Fire and Emergency Medical Services vehicles, care
must be exercised in not locating speed humps on routes where there is relatively frequent use by
such vehicles.
