INSTALLING AND MAINTAINING TEMPORARY SPEED HUMPS AND TRAFFIC CIRCLES

Concord, California, like most communities, receives requests and complaints from residents regarding high travel speeds and traffic volumes on neighborhood streets. To address neighborhood concerns, Concord undertook a program to install temporary speed humps and traffic circles. The devices, made from recycled tires, can be installed and removed in one day. The devices were tested for effectiveness and durability within the City's maintenance yard before installing them on the street. This paper focuses on testing, installation, and maintenance of temporary speed humps and traffic circles. Problems and follow-up actions encountered during device testing in the City's maintenance yard will be documented. The paper addresses field implementation including pre-construction and installation procedures. Installation procedures are illustrated to assist communities in completing similar installations. Finally, the paper identifies on-going maintenance activities.
