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.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Hurricanes are one of the most catastrophic events resulting in severe consequences including loss of life and property damage. Emergency management teams play a huge role in safeguarding the lives of people in endangered areas by evacuating them to safer locations as efficiently as possible. This study was undertaken to evaluate the traffic control plan (TCP), for the Hampton Roads region of Virginia, and the performance of the designated evacuation routes using large-scale traffic simulation models. Road network was coded in a state-of the- art microscopic simulation program, VISSIM. The emergency evacuation plan for the study area was evaluated by simulating the various evacuation scenarios as described in the abbreviated transportation model (ATM) for Hampton Roads region. The study area comprised of the following nine evacuation areas - cities of Virginia Beach, Norfolk, Chesapeake, Portsmouth, Suffolk, Hampton, Newport News, Poquoson, and York. The following objectives were achieved in this research - 1) estimated the traffic performance of evacuation routes and other major arterial streets, 2) located the major bottlenecks, congestion, or other operational difficulties in the areas covered by the network, 3) estimated the total network evacuation time, 4) conducted what-if scenarios (e.g., incident occurrences), and 5) recommended amendments to the TCP to improve the traffic performance.

This book was released on 2008-11-10 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first practical guide to infrastructure security using Intelligent Transportation Systems (ITS) Intelligent Transportation Systems, or ITS, integrates different computing, control, and communication technologies to help monitor and manage traffic management that helps reduce congestion while saving lives, time, and money. While mobility and safety are the primary objectives of any good transportation system, security has also become an equally important consideration in their design and operation. This book provides a comprehensive treatment of techniques to leverage ITS in support of security and safety for surface transportation infrastructure. Through the book's multidisciplinary approach, readers gain a comprehensive introduction to the diverse aspects of transportation infrastructure security as well as how ITS can reduce risks and be protected from threats with such topics as computer systems, risk analysis, and multi-modal transportation systems. This book, which will serve as a textbook and guide, provides: Current ITS approaches to security issues such as freight security, disaster and evacuation response, HAZMAT incidents, rail security, and ITS Wide Area Alerts Guidance on the development of a regional transportation security plan Securing ITS itself and privacy issues involved in any collection and use of personally identifiable tracking data Exercises, question-and-answer sections, and other helpful review tools for the reader Filling a gap in the practical application of security, Transportation Infrastructure Security Utilizing Intelligent Transportation Systems offers both students and transportation professionals valuable insights into the new security challenges encountered and how to manage these challenges with the use of computerized transportation systems.

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.

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.

Book excerpt: Hurricane evacuation has attracted renewed emphasis since hurricane Katrina in 2005. Every coastal state is establishing their evacuation guidelines and searching new methods to improve evacuations. In this dissertation, first, hurricane evacuation of the Hampton Roads region of Virginia is investigated using large-scale regional mesoscopic traffic simulation models. Fourteen evacuation scenarios consisting of various combinations of storm categories and traffic control strategies are evaluated. The evaluation of scenarios provided information on the clearance time, average travel times, bottleneck locations, and congestion durations. The major findings from scenario evaluations include: (1) The differences in participation rates (100% versus 70%) did not impact the clearance times in a Category 1 storm evacuation, but have significant impact in a Category 3 storm evacuation, (2) The status (open or close) of a critical tunnel crossing, the Monitor-Merrimac Memorial Bridge-Tunnel did not have impact on the evacuation performance in Category 1 and 2 storm. However, opening the tunnel would improve the performance in a Category 3 storm, (3) The clearance times derived from simulations can be used to determine when to issue evacuation orders for various storm intensities, and (4) The bottleneck locations and durations identified for each evacuation scenario can be used to allocate the limited traffic monitoring equipment during an evacuation. The second focus of this dissertation is to investigate the impact of assumptions made regarding evacuee route choice on evacuation performance estimates. In the hurricane evacuation literature, very few studies have documented the realistic route choice behavior of evacuees during a hurricane. Due to this lack of realistic route choice behavior data, modelers make assumptions about the route choice behavior and traffic assignment. User-equilibrium traffic assignment has been extensively used in past evacuation studies. In this dissertation, realistic route choice behavior was determined by evaluating findings of a few published studies. The impact of route choice behavior on evacuation performance, especially travel times, is then investigated using the regional simulation model of the Hampton Roads region. The analysis found that the user-equilibrium traffic assignment significantly underestimates the travel times during an evacuation. The extent of underestimation of evacuation travel times depends on the total evacuation demand (a function of storm intensity), and the percent of evacuees willing to use en-route information to seek alternate routes when facing congestion. For the three en-route percentages reported in the literature i.e., 30%, 50%, and 70%, the UE travel times were 58%, 42%, and 33% lower than actual travel times realized in a Category 1; 94%, 71%, and 57% lower in a Category 2; and 90%, 69%, and 54% lower in a Category 3 evacuation. These findings illustrate the need to collect real-world data on evacuee route choice in order to build accurate evacuation models. The third focus of dissertation is to propose a procedure to assess the benefit of adding additional intermediate crossovers on a contra flow facility. Contra flow operation in which the direction of traffic on one or more travel lanes is reversed in order to increase the capacity of a road network is becoming a critical component of the evacuation plans of coastal states. Several coastal states have a contra flow plan in place for evacuation, however only a few states have intermediate crossovers between the origin and termination points. The impact of intermediate crossovers on network performance has not been well investigated in previous research. This dissertation investigates the benefits of having intermediate crossovers between regular and contra flow lanes. Based on the investigation, it can be concluded that adding intermediate crossovers did improve network performance for medium and high evacuation demand situations. Adding intermediate crossovers for low demand situations did not improve the network performance and thus any considerations for intermediate crossovers for the low demand evacuations must be based solely on providing access to road-side services (gas, food, and others). For high and medium demand situations and for the road network studied in this section, a 28% improvement in the average travel time was observed by deploying four intermediate crossovers out of the 44 potential crossover locations. The iterative elimination procedure proposed in this dissertation is the first attempt in the literature to provide a systematic approach to determine the critical intermediate crossover locations within reasonable computation times.
