Title:

Amber Alert and Major Catastrophe Messages on Dynamic Message Signs: Focus Group Studies in Texas

Abstract:

Texas DOT wanted to expand their DMS Message Design and Display Manual to include information related to AMBER alerts and specific major catastrophes (including weather-related conditions). The objectives were to obtain initial responses from drivers concerning information needs and to help develop potential messages for further study. Regarding flooding, participants were split as to whether they would continue to drive if the message said "FLOODED". The consensus of those that would continue was that the message should include information regarding the location of the flooding or an exit to use. Also, no consensus was found for a term describing this situation, although "FLOODED" was used in messages designed by five of the six groups. For hurricanes, information needs identified far exceed what can be accommodated via DMS. However, the information needs cited provide valuable insights into the initial perspectives of motorist needs during evacuations.
