This is a Civil thesis which studies approaches for signal timing to facilitate evacuation and response in the event of a no-notice urban evacuation. A simulation model was constructed with data from Washington, D.C. Experimental results indicate that significant trade-offs exist in setting timing plans as long cycle lengths can lead to reduced evacuation times, but at the expense of delay on minor roadways. Best compromise plans employ cycle lengths greater in length than used in ordinary peak hour plans, giving significantly more green time to the main evacuation routes than to minor roadways as used in peak hour plans.
