- Establish reliable communication systems to stay in touch with the outer world in case of emergency. Reliable communications technology is particularly important for transportation agencies, in which many employees may be working in the field, driving vehicles or otherwise away from the central offices of the agency. The importance of accurate, frequent, and calming communication can be forgotten in the height of a crisis, as emergency responders focus on managing the immediate demands of the situation.
- Use ITS effectively to disseminate travel related updates promtly during an emergency. Communication is vital and can facilitate the resolution of the crisis by encouraging cooperation and discouraging panic. On September 11, ITS technologies deployed in the New York City metro area aided both agencies and travelers in several ways. Most importantly, ITS were able to alert motorists to problems long before they reached the Manhattan area. Variable message signs (VMS) were used to communicate real-time information to travelers. Within two minutes of the decision to close the George Washington Bridge, the VMS alerted motorists ten miles away. The information provided by its 1-800 telephone lines was simultaneously updated, and the information was electronically transmitted for broader dissemination.
- Consider several means of communication to inform the public of emergency related travel directions and updates. Since the 1994 Northridge earthquake, the transportation management center (TMC) staff has updated the tools for relaying traffic information. Cable Television is now used, real-time traffic information is available on the Internet, and Teletext—a scrolling sign placed at key points in the freeway system—alerts commuters to backups. For the Baltimore rail tunnel fire, the most significant contribution from advanced technology was VMS and HAR (highway advisory radio) which provided information to travelers on the closing of roadways into Baltimore. Maryland’s CHART TMC posted messages on the portions of the Interstate system impacted by the incident.
- Strive to establish interoperability among communication systems used by key agencies responding to catastrophes. The lack of interoperability between the communication systems of different agencies was a major obstacle to inter-agency cooperation during each of the events noted above, and intra-agency communications were hampered by the lack of sustained and reliable communications systems. Agency representatives highlighted the importance of having in place established modes and protocols of communication for telephone, fax, or Internet connections, with particular attention paid to ensuring redundancy in those systems.
 CHART (www.chart.state.md.us) is a joint effort of the Maryland Department of Transportation, Maryland Transportation Authority and the Maryland State Police, in cooperation with other federal, state and local agencies. CHART's mission is to improve "real-time" operations of Maryland's highway system through teamwork and technology.
