New York State ranks prominently among other states in the nation in the size and scope of its transportation system, with most of the usage of that system concentrated in and around New York City. Areas of infrastructure density and bottlenecks pose security challenges. Moreover, transportation is highly dependent on other infrastructure. Research addressing the reduction of security threats is proposed in terms of transportation operations and expediting recovery. Existing research is presented on transit recovery in the New York area after September 11, 2001 as a guide for future research into prevention of, and recovery from, disruptions to transit.
