- Title
- Transit signal priority for emergency evacuation: mitigating disaster.
- Creator

- Abstract/Description

The goal of this research is to answer a single question. During an urban evacuation, is it advisable for regional planners to allow transit units signal priority in cases where police assisted traffic controls are not an option? Standard practice for emergency evacuation is to place police officers at intersection throughout the evacuation area. However, this is not always an option where environmental factors such as the presence of fire, chemical plume, radioactive fallout (nuclear...
Show moreThe goal of this research is to answer a single question. During an urban evacuation, is it advisable for regional planners to allow transit units signal priority in cases where police assisted traffic controls are not an option? Standard practice for emergency evacuation is to place police officers at intersection throughout the evacuation area. However, this is not always an option where environmental factors such as the presence of fire, chemical plume, radioactive fallout (nuclear contaminated wind and dust) do not permit police presence. Results from a case study conducted on Washington D.C. show that it would take four non-prioritized transit units to accomplish the same task as three prioritized vehicles. Furthermore, allowing transit signal priority during an urban evacuation has little to no effect on evacuation clearance time or evacuee travel time. Moreover, when transit signal priority is restricted to operate only on evacuation routes, evacuee travel and delay time decreases.

- Abstract/Description

Catastrophic events in the past revealed the need for more research in the field of emergency evacuation. During such a procedure, different problems such as congestion at the related traffic networks because of the large number of the evacuating vehicles can occur. Current best practices, in order to deal with such problems, suggest the further involvement of buses in evacuation operations. On the first part of this study after the accurate development of the related simulation model, the...
Show moreCatastrophic events in the past revealed the need for more research in the field of emergency evacuation. During such a procedure, different problems such as congestion at the related traffic networks because of the large number of the evacuating vehicles can occur. Current best practices, in order to deal with such problems, suggest the further involvement of buses in evacuation operations. On the first part of this study after the accurate development of the related simulation model, the optimization of a selected bus system characteristics focusing on the vehicle routing parameter will follow through the development and the application of a non-linear cost minimization problem. On the second part, the potential use of the regular-everyday bus routes in a no-notice emergency evacuation in order to save time comparing to the time needed so as to assign the actual evacuation routes to the evacuation bus vehicles will be analyzed.

- Title
- An emergency evacuation planning model for special needs populations utilizing public transit systems.
- Creator
- Hess, Linda S., College of Engineering and Computer Science, Department of Civil, Environmental and Geomatics Engineering
- Abstract/Description
-
The need to have evacuation plans in place for readily implementation for special need populations has become evident after catastrophic events such as Hurricane Katrina. For the purpose of this research special need populations will include, but are not limited to, people with physical disabilities, senior citizens, non-English speaking populations, residents and employees without vehicles, and tourists. The main objective of this research is to evaluate different evacuation procedures for...
Show moreThe need to have evacuation plans in place for readily implementation for special need populations has become evident after catastrophic events such as Hurricane Katrina. For the purpose of this research special need populations will include, but are not limited to, people with physical disabilities, senior citizens, non-English speaking populations, residents and employees without vehicles, and tourists. The main objective of this research is to evaluate different evacuation procedures for special need populations from large urban areas utilizing current public transit systems. A microscopic simulation model was constructed to analyze real life scenarios for evacuation methodologies. A linear programming optimization model was developed to find the optimum locations for evacuation bus stops for the case study area. The results from this research were very interesting and can aid evacuation planners in the future.

- Catastrophic event planning and response for urban areas through dynamic traffic assignment and departure time-slot allocation.

- Degnan, William C., College of Engineering and Computer Science, Department of Civil, Environmental and Geomatics Engineering
- Abstract/Description

Catastrophic event emergency planning has emerged as one of the most important operations management areas. Much of the successes of a response plan rely on the ability to maintain an operating transportation infrastructure. In recent years urban areas have become susceptible to biological terrorist attacks due to their size and demographics.

Show moreCatastrophic event emergency planning has emerged as one of the most important operations management areas. Much of the successes of a response plan rely on the ability to maintain an operating transportation infrastructure. In recent years urban areas have become susceptible to biological terrorist attacks due to their size and demographics. To mitigate the devastating effects of an attack, a comprehensive catastrophic event response plan is devised. The characteristics of the disease (dormant periods, signs/symptoms), daily traffic operations and trip distributions, patient-choice hospital modeling and emergency center corridor optimization are all elements of an effective response plan. Simulation and optimization modeling of this plan becomes a faster-than-real-time tool in replicating urban area degradation. Therefore, allowing planners to identify "worst case scenarios" within the network and implement Dynamic Traffic Assignment (DTA) techniques and a non-linear departure time slot allocation mathematical model ensuring infected populations receive treatment and/or vaccinations efficiently.
