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.

Book A Transportation Guide for All hazards Emergency Evacuation

Download or read book A Transportation Guide for All hazards Emergency Evacuation written by Deborah Matherly and published by Transportation Research Board. This book was released on 2013 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: "TRB's National Cooperative Highway Research Program (NCHRP) Report 740: A Transportation Guide for All-Hazards Emergency Evacuation focuses on the transportation aspects of evacuation, particularly large-scale, multijurisdictional evacuation. The guidance, strategies, and tools in NCHRP Report 740 are based on an all-hazards approach that has applicability to a wide range of "notice" and "no-notice" emergency events. The report follows the basic planning steps of the Federal Emergency Management Agency's Comprehensive Preparedness Guide (CPG) 101. Each chapter parallels one of the six main CPG steps. Each chapter is further subdivided into smaller, discrete tasks, with cross-references to tools--such as templates or checklists--that are shown at the end of each chapter and are on a CD-ROM included with the print version of the report."--Publisher's description.

Book Modeling Hurricane Evacuation Traffic

Download or read book Modeling Hurricane Evacuation Traffic written by Haoqiang Fu and published by . This book was released on 2006 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Little attention has been given to estimating dynamic travel demand in transportation planning in the past. However, when factors influencing travel are changing significantly over time - such as with an approaching hurricane - dynamic demand and the resulting variation in traffic flow on the network become important. In this study, dynamic travel demand models for hurricane evacuation were developed with two methodologies: survival analysis and sequential choice model. Using survival analysis, the time before evacuation from a pending hurricane is modeled with those that do not evacuate considered as censored observations. A Cox proportional hazards regression model with time-dependent variables and a Piecewise Exponential model were estimated. In the sequential choice model, the decision to evacuate in the face of an oncoming hurricane is considered as a series of binary choices over time. A sequential logit model and a sequential complementary log-log model were developed. Each model is capable of predicting the probability of a household evacuating at each time period before hurricane landfall as a function of the household's socio-economic characteristics, the characteristics of the hurricane (such as distance to the storm), and policy decisions (such as the issuing of evacuation orders). Three datasets were used in this study. They were data from southwest Louisiana collected following Hurricane Andrew, data from South Carolina collected following Hurricane Floyd, and stated preference survey data collected from the New Orleans area. Based on the analysis, the sequential logit model was found to be the best alternative for modeling dynamic travel demand for hurricane evacuation. The sequential logit model produces predictions which are superior to those of the current evacuation participation rate models with response curves. Transfer of the sequential logit model estimated on the Floyd data to the Andrew data demonstrated that the sequential logit model is capable of estimating dynamic travel demand in a different environment than the one in which it was estimated with reasonable accuracy. However, more study is required on the transferability of models of this type, as well as the development of procedures that would allow the updating of transferred model parameters to better reflect local evacuation behavior.
