Incident response systems use technologies to assist transit agencies to react faster and more efficiently to incidents and emergencies. For area-wide evacuations, many agencies can utilize the regional 511 planning system. The degree of success is contingent upon the agency's ability to collect and organize their data efficiently and effectively so that they can be shared with regional partners. While the 511 systems are developed for general information about travel services, if transit systems participate than they can communicate to the public about specific emergency conditions relevant to transit as well.
Communications with law enforcement, fire, and emergency medical teams is extremely important for incident response. This can sometimes be achieved through radio interoperability with other agencies when the transit system operates as a part of the county administration. In other cases, cell phone-based communications must be relied upon, which is less than ideal due to lost signals and capacity constraints.
