Drivers become aware of the speed they are traveling and many slow down. The trailer can be used on most streets that are wide enough to park the trailer out of the way of traffic. It cannot be set up on streets where it will be even partially in the travel lane. Pavement undulations are only used after all other efforts have been exhausted. In addition, they can only be installed on streets that meet established engineering criteria.
Many neighborhoods have homeowners associations or a neighborhood watch group.
It is often helpful for these groups to circulate newsletters notifying all residents of any neighborhood problems including speeding. Many times area residents are unaware of their speed and its affect on their neighbors. Stop signs are not successful in slowing traffic. Drivers try to make up for the delay by speeding up between stop controlled intersections. This quick acceleration increases noise and air pollution near the signs.
