This book was released on 2006 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Hampton Roads region of Virginia has developed a hurricane evacuation plan to facilitate the movement of large numbers of vehicles as they attempt to leave the region in advance of a storm. Although the plan considers many aspects of hurricane evacuation, this evaluation focuses on its impacts on traffic operations. A traffic control plan (TCP) was developed that describes the procedures to be followed in the event an evacuation is ordered. Ramps providing access to I-64 are designated as open or closed, and many are metered in an attempt to influence the route choice of evacuees and thereby balance the demand across available evacuation routes. Although considerable work has gone into the development of the TCP, it has not been evaluated from a microscopic perspective to determine the performance characteristics with respect to traffic flow. This study provides that microscopic analysis for the freeway portions of the evacuation routes. The evaluation found that under less severe hurricane conditions (Category 1 or 2), the TCP performs reasonably well under the assumptions made in this study. The most significant assumption made was that all background traffic, including individuals evacuating their homes but remaining within the region, will not use the interstates during the evacuation period. Although background traffic will likely exist, there was insufficient information available in this phase of the study to assign background traffic to the network in any reasonably accurate manner. As the intensity of the hurricane intensifies to a Category 3 or 4, the TCP begins to be less effective. Ramp metering rates, designed in the TCP to ensure free-flowing conditions on the interstate mainlines, result in significant queues at the ramps and back onto the arterial network. Under Category 4 conditions, these queues would likely result in gridlock throughout the arterial network and lead evacuees to search out alternative routes, possibly negatively impacting the performance of those routes as well. The evaluation concludes that lane reversal is warranted under any storm predicted to make landfall as a Category 4 or higher and should be strongly considered for any Category 3. The study further finds that when lane reversal is implemented, the ramp metering rates should be significantly increased to reduce ramp queuing and allow more efficient use of available mainline capacity. The recommendations offered in this report will help to ensure an efficient evacuation of vehicles from the Hampton Roads region, should one be required. The revised ramp metering strategies and guidance on the use of lane reversal will help to maximize the available capacity provided by the interstate routes. Assumptions made throughout the study could render the results uncertain. Background traffic using the interstate routes could add to the congestion reported here. In addition, conditions outside the bounds of the network modeled in this project could negatively impact evacuating vehicles leaving Hampton Roads.

Download or read book Large Scale Evacuation written by Michael K. Lindell and published by CRC Press. This book was released on 2018-12-07 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large-Scale Evacuation introduces the reader to the steps involved in evacuation modelling for towns and cities, from understanding the hazards that can require large-scale evacuations, through understanding how local officials decide to issue evacuation advisories and households decide whether to comply, to transportation simulation and traffic management strategies. The author team has been recognized internationally for their research and consulting experience in the field of evacuations. Collectively, they have 125 years of experience in evacuation, including more than 140 projects for federal and state agencies. The text explains how to model evacuations that use the road transportation network by combining perspectives from social scientists and transportation engineers, fields that have commonly approached evacuation modelling from distinctly different perspectives. In doing so, it offers a step-by-step guide through the key questions needed to model an evacuation and its impacts to the evacuation route system as well as evacuation management strategies for influencing demand and expanding capacity. The authors also demonstrate how to simulate the resulting traffic and evacuation management strategies that can be used to facilitate evacuee movement and reduce unnecessary demand. Case studies, which identify key points to analyze in an evacuation plan, discuss evacuation termination and re-entry, and highlight challenges that someone developing an evacuation plan or model should expect, are also included. This textbook will be of interest to researchers, practitioners, and advanced students.

This book was released on 2013-06-06 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Pipeline and Hazardous Materials Safety Administration of the U.S. Department of Transportation defines hazardous materials (hazmat) as a substance or material capable of posing an unreasonable risk to health, safety, or property when transported in commerce. Hazmat accidents can result in significant impact to the population (death, injuries) and damage to the environment (destroyed or damaged buildings and infrastructure). Further, hazmat, especially explosive materials, can potentially be used by terrorists to attack civilians or to destroy critical infrastructure. This handbook provides models from Operations Research and Management Science that study various activities involving hazmat transportation: risk assessment, route planning, location decisions, evacuation planning, and emergency planning for terrorist attacks. There are two important research areas in hazmat transportation that are widely studied in the literature: risk assessment and shipment planning. In the risk assessment area, important issues include measurement of accident probabilities and consequences in hazmat transport. Example works in the risk assessment area include modeling risk probability distribution over given areas, considering hazmat types and transport modes, and environmental conditions. The first half of this handbook covers the two fields of risk assessment and shipment planning, while the second half of this handbook provides useful models and insights on other important issues including location problems for undesirable facilities, network interdiction, terrorist attack, and evacuation.

Book excerpt: Transportation in cities, with its related environmental and social concerns continues to be a topic of the utmost priority for urban authorities and central governments around the world. Frequently, the concern is not orderly but driven by the safety crises, which take place regularly, and even the best-planned urban transport systems require considerable studies to safeguard their safety, maintenance and operational use. On a broader front, the continuing need for better urban transport systems in general and the need for a healthier environment has led to an increased level of research around the world. This is reflected in the proceedings of the Thirteenth International Conference on Urban Transport and the Environment in the 21st Century, which stresses the continuous steady growth and research into the urban transport systems control aspects, information and imulation systems. All these topics continue to be of importance for analyzing the complex inter-relation of the urban transport environment and for establishing action strategies for transport and traffic problems. Of interest to engineers, scientists and managers working in industry, universities, research organizations and government involved in the planning and management of urban transportation systems and transport policy, this book contains papers within the following subject areas: Environmental and ecological considerations; Information systems and GPS applications; Intelligent transport systems; Intermodel passenger transport systems; Land use and transport integration; Modality in freight; Public transport systems; Road pricing; Traffic management; Transport automation; Transport logistics and operations research; Transport modelling and simulation; Transport security and safety; Transport sustainability; Transport technology; Urban transport planning.

Download or read book Computer Simulation based Framework for Transportation Evacuation in a Major Trip Generator written by Fengxiang Qiao and published by . This book was released on 2009 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since emergencies including both natural disasters and man-made incidents, are happening more and more frequently, evacuation, especially transportation evacuation, is becoming a hot research focus in recent years. Currently, transportation evacuation study focuses on evacuating people and property from large areas and does not address the problem of transportation evacuation in a small and dense area. This research is intended to identify the study framework of developing transportation evacuation plans in small and dense areas. Texas Medical Center (TMC), Houston, Texas, is selected as case study in this thesis. Incidents are assumed based on potential threats. Traffic information is collected through filed data collections in the TMC area, and evacuation scenarios with incidents and management improvements are coded and simulated in VISSIM, a microscopic traffic simulation model. Genetic Algorithm is one of the calibration methods for searching multiple parameters at the same time and is used in this thesis to calibrate parameters of driving behaviors in VISSIM by using field collected and simulation data. Based on the simulation results, potential improvements and measurement of effectiveness (MOE) of operations such as Reversed Lane (RL) and In-bound Shuttle (IS) are analyzed and evaluated. Simulation results show that the evacuation would be much more efficient if appropriate operational strategies are implemented. Proper management improvements such as Reversed Lane and In-bound Shuttle could greatly maximize the number of persons/vehicles evacuated in the area. The selected operational plan can efficiently evacuate all persons in the Texas Medical Center in suitable simulation scenario under a given incident assumption. The framework of developing transportation evacuation plan is tested and proven to be effective in the Texas Medical Center. The microscopic simulation based study process is targeted on small and dense areas and it can be used in any other similar areas. It is recommended that further work be conducted to form a comprehensive evacuation plan.

Download or read book Hurricane Preparedness and Recovery by a Transportation Agency written by and published by . This book was released on 2002 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: A hurricane can be crippling to a regional transportation system such as the Hampton Roads District of Virginia. Preparedness and recovery by the highway agency, in coordination with localities and emergency services, is critical to minimizing the short, medium, and longterm effects of the event. In prior efforts, investigators characterized costs, risks, and benefits of managing spares of signs, signals, and lights in anticipation of hurricane damage (Lambert et al. 1998). In addition, use was made of probabilistic hurricane forecasts for inventory planning and operation. Based on the prior efforts, the research problem is identified as follows: (1) improving the basis for priority setting in recovery efforts; and (2) adoption elsewhere (i.e., in addition to sign-signal-light inventory) in the agency of risk-cost-benefit assessments and evaluation to improve the agency's preparedness and response capability.

Download or read book Developing and Maintaining Emergency Operations Plans written by United States. Federal Emergency Management Agency and published by . This book was released on 2010 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive Preparedness Guide (CPG) 101 provides guidelines on developing emergency operations plans (EOP). It promotes a common understanding of the fundamentals of risk-informed planning and decision making to help planners examine a hazard or threat and produce integrated, coordinated, and synchronized plans. The goal of CPG 101 is to make the planning process routine across all phases of emergency management and for all homeland security mission areas. This Guide helps planners at all levels of government in their efforts to develop and maintain viable all-hazards, all-threats EOPs. Accomplished properly, planning provides a methodical way to engage the whole community in thinking through the life cycle of a potential crisis, determining required capabilities, and establishing a framework for roles and responsibilities. It shapes how a community envisions and shares a desired outcome, selects effective ways to achieve it, and communicates expected results. Each jurisdiction's plans must reflect what that community will do to address its specific risks with the unique resources it has or can obtain.

Available in PDF, EPUB and Kindle. Book excerpt: This is a print on demand edition of a hard to find publication. Hurricane Katrina, in Aug. 2005, was the costliest hurricane as well as one of the five deadliest storms in U.S. history. It caused extensive destruction along the Gulf coast from central Florida to Texas. Some 22,000 Active-Duty Army personnel assisted with relief-and-recovery operations in Mississippi and Louisiana. At the same time, all 50 states sent approx. 50,000 National Guard personnel to deal with the storm¿s aftermath. Because the media coverage of this disaster tended toward the sensational more than the analytical, many important stories remain to be told in a dispassionate manner. This study offers a dispassionate analysis of the Army¿s response to the natural disaster by providing a detailed account of the operations in Louisiana and Mississippi.
