Know Your Vital Signs
In the mid-1990s, TxDOT, backed by TTI research, changed its practice for selection and use of more than a dozen traffic control devices. The department also changed the design of several other signs. Once the changes were made, TTI and TxDOT implemented a statewide public information campaign-Know Your Vital Signs. From the distribution of brochures, CD-ROMs, videos and slide shows to drivers of all ages, the Vital Signs message was well received. As a result, numerous traffic environments in Texas have been made safer by signs and signals that are more easily understood than before.
