America's Container Ports: Linking Markets at Home and Abroad

Show summary Open resource [pdf] (open full abstract)
"The U.S. marine transportation system handles large volumes of domestic and international freight in support of the Nation's economic activities. As a vital part of that system, the Nation's container ports handle cargo and are sources of employment, revenue, and taxes for businesses or communities where they are located. This report provides an overview of the movement of maritime freight handled by the Nation's container ports in 2009 through mid-2010, based on the most current available data through that time period. It summarizes trends in maritime freight movement since 1995, especially during the last 5 years. It also covers the impact of the recent U.S. and global economic downturn on container traffic; trends in container throughput; concentration of containerized cargo at the top U.S. ports; regional shifts in cargo handled, vessel calls, and port capacity; the rankings of U.S. ports among the world's top ports; and the number of maritime container entries into the United States relative to truck and rail containers. The report also includes spotlight summaries of landside access to con¬tainer ports and maritime security initiatives."

Communicating with the Public Using ATIS during Disasters: A Guide for Practitioners

Show summary Open resource [pdf] (open full abstract)
"Advanced Traveler Information Systems, ATIS, can play an important role in communicating essential information to the public during disasters. Variable message signs, 511 telephone systems, highway advisory radio, and websites are some of the dissemination devices of systems that collect, process, and disseminate information about travel conditions to the public for day-to-day transportation operations, and these same systems need to be effectively used during disaster situations. This document provides advice on use of ATIS during disasters and is intended not only for state and local transportation agencies but for their partners in public safety and emergency management agencies. It offers practical guidance to managers of transportation management centers and emergency operations and to public information officers who may be called on to staff joint information centers during disasters. The document discusses what we know about human behavior in disaster situations based on findings from several decades of research. That perspective can help in maximizing the effectiveness of traveler information communications. The current use of traveler information in managing normal incidents and planned special events is examined as a starting point for gauging the processes and technologies that are in place today. Five case studies of actual disasters in Georgia, California, Nevada, Utah, and Washington State show the role that traveler information has played in current practice and provide lessons for others. A concept of operations is presented that characterizes the flow of information among the people, organizations, and technologies comprising traveler information dissemination during disasters."

Evacuation Management Operations (EMO) Modeling Assessment: Transportation Modeling Inventory

Show summary Open resource [pdf] (open full abstract)
"This report documents more than thirty surface transportation modeling tools that have been applied or could be applied to evacuation modeling. Each tool represents a tradeoff between desired scope and analytical complexity, ranging from state-to-state coordination tools such as the Evacuation Traveler Information System (ETIS) to detailed traffic micro-simulation models such as the TSIS/CORSIM traffic simulation model. Based upon a comprehensive literature review, the report first provides a summary of evacuation event types and then a description of the three general classes of modeling approaches (macro, meso, micro) currently used to model evacuation events. The modeling inventory includes a description of each modeling tool and cites case studies (if any) where the tool has been used in modeling evacuation events. Some tools have been developed to model specific types of evacuations, others have more general applications. The modeling inventory concludes with an analysis of the tools as they relate to a modeling spectrum according to scope and analytical complexity, including a discussion of how the decisions supported by analysis drive tradeoffs in terms of scale and computational speed."

U.S. Rural Population and Scheduled Intercity Transportation in 2010: A Five-Year Decline in Transporation Access

Show summary Open resource [pdf] (open full abstract)
"Between 2005 and 2010, 3.5 million rural residents lost access to scheduled intercity transportation, increasing the percent of rural residents without access to intercity transportation from 7 to 11 percent. In 2005, 5.4 million rural residents lacked access to intercity transportation, with that total increasing to 8.9 million rural residents in 2010. Of the 71.7 million rural residents retaining access in 2010, 3.7 million lost access to more than one intercity transportation mode during the 5-year period. These numbers update a 2005 analysis by the Bureau of Transportation Statistics (BTS) of the U.S. Department of Transportation's Research and Innovative Technology Administration. In 2005, BTS measured access to intercity transportation within rural America. At the time, BTS calculated that 93 percent of rural residents in the United States lived within the coverage area of at least one of the four intercity public transportation modes (air, bus, ferry, and rail). Since then, significant changes have occurred to the networks of several of the modes. These changes include, but are not limited to, network reductions made by Greyhound and the suspension of the New Orleans--Jacksonville route previously provided by Amtrak's Sunset Limited. In this report, rural areas within a specified reasonable distance of intercity air, bus, ferry, or rail transportation (hereafter referred to as the four intercity public transportation modes) are considered to have intercity transportation access to that mode. Rural residents living within a reason¬able distance of more than one mode are counted once in the total number of rural persons with access to intercity transportation and once in the total for each mode providing coverage."

Disaster Response and Evacuation User Service: An Addendum to the ITS Program Plan

Show summary Open resource [pdf] (open full abstract)
"The surface transportation system plays a crucial role in responding to natural disasters, terrorist acts, and other catastrophic events. The Disaster Response and Evacuation (DRE) User Service uses intelligent transportation systems (ITS) to enhance the ability of the surface transportation system to respond to and recover from such disasters. The user service provides enhanced access to the scene for response personnel and resources, provides better information about the transportation system in the vicinity of the disaster, and provides more efficient, safer evacuation for the general public if needed. In addition, the transportation system includes a wealth of trained professionals and resources that constitute a portion of the disaster response. Use of ITS to prioritize, allocate, and track these personnel and resources also provides a more effective response to disasters. All types of disasters are considered in this user service including natural disasters (hurricanes, earthquakes, floods, winter storms, tsunamis, etc.) and technological and man-made disasters (hazardous materials incidents, nuclear power plant accidents, and national security emergencies such as terrorism, nuclear, chemical, biological, and radiological weapons attacks terrorist acts.). The basic ITS capabilities for disaster response and evacuation are essentially the same in all of these scenarios, although specific disasters do have unique characteristics (e.g., the amount of warning available, responder risks, local site management (is it a crime scene?), chances for secondary events, recovery operations required, scope and scale of the damage). Broad inter-agency coordination is critical in disaster scenarios, with transportation professionals performing well-defined roles in the larger context of the multi-agency response to the disaster."

Motorcoach Fire Safety Analysis: The Causes, Frequency, and Severity of Motorcoach Fires in the United States

Show summary Open resource [pdf] (open full abstract)
"The Federal Motor Carrier Safety Administration's (FMCSA) mission is to reduce crashes, injuries, and fatalities on our nation's roads involving motor vehicles, and to further its work the agency set out to identify ways to reduce motorcoach fire risk. FMCSA's Vehicle and Roadside Operations Division contracted the Volpe National Transportation Systems Center to perform a study to collect and analyze information from government, industry, and media sources on the causes, frequency, and severity of motorcoach fires in the United States, and to identify potential risk reduction measures. Volpe Center analysts only considered fires that were mechanical or electrical in origin, and that were neither the result of a collision nor arson. This study establishes an integrated incident database, allowing for a comprehensive analysis of risk trends and patterns, and provides recommendations that could result in fewer motorcoach fires and, in turn, safer roads and lives saved. Volpe Center analysts created a database on reported motorcoach fire incidents between 1995 and 2008 as a basis for the study. The resulting database consists of 899 records from the sources cited below spanning the years 1995--2008, with the 2004--2006 data being the most complete. Analysts constructed the database to facilitate analysis by location of origin, point of ignition, geographic and vehicle characteristics, inspection and maintenance histories, vehicle damage, and human injuries and fatalities. The data sources for this study included the U.S. Fire Administration's (USFA) National Fire Incident Reporting System (NFIRS), FMCSA's Motor Carrier Management Information System (MCMIS), the National Highway Traffic Safety Administration's (NHTSA) State Data System (SDS), and NHTSA's Fatality Analysis Reporting System (FARS). R.L. Polk and Co. provided summaries of motorcoach registrations and detailed characteristics data. Additional motorcoach fire records were compiled by two major carriers and two insurance firms. Volpe Center analysts used independent sources to verify that incidents were applicable, to address missing or unknown field values, and to derive non-reported elements."

Risk of Commercial Truck Fires in the United States: An Exploratory Data Analysis

Show summary Open resource [pdf] (open full abstract)
"Large trucks are involved in only 8 percent of fatal crashes per year, but 17 percent of fatal fires. The scope of the current body of research is limited. Studies have treated truck fires generally as a subset of vehicle fires or in their own right on a smaller scale, confined to a limited pool of data. This study, commissioned by the Volpe National Transportation Systems Center (Volpe Center) for the Federal Motor Carrier Safety Administration (FMCSA), expands the current body of research to collect and analyze information from government, industry, and media sources on the magnitude, trends, and causes of truck fires in the United States and to identify potential risk-reduction measures. This study succeeds FMCSA's Motorcoach Fire Safety Analysis (2009), furthering the agency's mission to improve commercial motor vehicle (CMV) safety on our nation's roads. Focusing on non-passenger CMVs with a Gross Vehicle Weight Rating (GVWR) of Class 4 and above, this study combines several government and industry data sources to investigate potential causal relationships across truck fire incidents, crash rates, and fatalities."

Comparison of the U.S. and European Approaches to Passenger Train Fire Safety

Show summary Open resource [pdf] (open full abstract)
"Although the number of fires occurring on passenger rail vehicles has been historically low, the consequences, when a fire does occur, can be catastrophic, depending on the location of the train and the operating environment, particularly if the fire occurs at night or in a tunnel. [...] Accordingly, fire safety is an area of particular importance for inter-city passenger and commuter railroad operations. A "systems" approach to fire safety addresses passenger rail equipment design and materials for fire prevention, fire detection and suppression, passenger evacuation, and the interrelationship between these elements. The Federal Railroad Administration (FRA) and other U.S. agencies and organizations, individual European countries, the International Union of Railways (UIC), and most recently, the European Committee for Standardization (CEN), have all developed performance requirements for passenger rail vehicles, intended to provide such a "systems" approach for passenger safety that includes but extends beyond fire behavior test methods and related performance criteria."

Deployment of ITS: A Summary of the 2010 National Survey Results

Show summary Open resource [pdf] (open full abstract)
"This report presents summary results of the 2010 ITS Deployment Tracking survey, the most recent survey conducted by the ITS Deployment Tracking Project. The U.S. Department of Transportation and its member agencies, including the Research and Innovative Technology Administration, have pursued a research and development agenda, the Intelligent Transportation System (ITS) Program, designed to integrate the latest in information technologies to improve the safety, mobility, and reliability of surface transportation modes. Within metropolitan areas, implementation of these advanced technologies has been accomplished by a variety of state and local transportation and emergency management agencies as well as the private sector. In order to measure the rate of ITS deployment within the nation's largest metropolitan areas, the ITS Deployment Tracking Project has conducted a nationwide survey of state and local transportation and emergency management agencies nearly every year since 1997. The results presented in this report are intended to be a summary of the entire database from the 2010 survey. Access to the complete survey results and previous national surveys are available on-line at http://www.itsdeployment.its.dot.gov. The website also provides access to survey results in the form of downloadable reports, including a survey summary for each survey type and fact sheets. Nearly 1,600 surveys were distributed to state and local transportation agencies in 2010. A total of seven (7) survey types were distributed including: Freeway Management, Arterial Management, Transit Management, Transportation Management Center (TMC), Electronic Toll Collection (ETC), Public Safety -- Law Enforcement, and Public Safety -- Fire/Rescue."

Transportation Safety by the Numbers

Show summary Open resource [pdf] (open full abstract)
"For the majority of Americans, driving or being a passenger in a motor vehicle is the most dangerous daily activity he or she will be undertaken. However, everyone can take steps to drive safely, such as avoiding the deadly 'Ds'--distracted or drunk driving. That is one of the reasons why transportation safety is a strategic priority of the U.S. Department of Transportation. According to the Centers for Disease Control, accidents (unintentional injuries) are the 5th leading cause of death in the United States. Transportation accidents account for 31.9 percent of the accidental deaths reported in 2010. Motor vehicle accidents or highway fatalities are responsible for the largest share, accounting for 93 percent of transportation‐related deaths. However, motor vehicle crashes have been trending downward, decreasing by 20.2 percent over the past 10 years, which has resulted in fewer motor vehicle fatalities and injuries. Many safety factors, including the safety measures, have contributed to this decline."

Unmanned Aircraft System (UAS) Service Demand 2015-2035: Literature Review & Projections of Future Usage

Show summary Open resource [pdf] (open full abstract)
"This report assesses opportunities, risks, and challenges attendant to future development and deployment of UAS within the National Airspace System (NAS) affecting UAS forecast growth from 2015 to 2035. Analysis of four key areas is performed: technology, mission needs, economics, and existing or anticipated challenges to routine use in NAS operations. Forecast effects of emerging technologies as well as anticipating new technological innovations in areas of airframes, powerplants, sensors, communication, command and control systems, and information technology and processing are evaluated. Anticipated mission needs include intelligence, surveillance and reconnaissance (ISR), as well as new areas such as stores delivery, cargo transport, search and rescue, and pilot augmentation; example business case models are developed for each of these areas. Challenges to routine UAS usage in the NAS include: absence of legislation and regulations for safe flight in integrated airspace; pilot training and certification; regulatory, policy, and procedural issues; social issues, such as privacy and nuisance concerns; environmental issues, such as noise and emissions; and safety. Provided these challenges are largely mitigated, the following are projections of UAS fleet size by user in 2035: Department of Defense ~14,000, with additional ~5,000 having optional pilot augmentation (Air Force ~3,500; Navy + Marines ~2,500; Army ~10,000); Public Agencies (Federal, State, & Local) ~70,000. Total UAS vehicles will approach ~250,000 by 2035, of which ~175,000 will be in the commercial marketplace. UAS operations are expected to surpass manned aircraft operations, for both military and commercial domains, by 2035."

"The Bureau of Transportation Statistics (BTS) Border Crossing/Entry Data provides summary statistics for incoming crossings at the U.S.-Canadian and the U.S.-Mexican border at the port level. Data are available for trucks, trains, containers, buses, personal vehicles, passengers, and pedestrians. Border crossing data are collected at border ports by U.S. Customs and Border Protection. The data reflect the number of vehicles, containers, passengers or pedestrians entering the United States. Customs and Border Protection does not collect comparable data on outbound crossings. Users seeking data on outbound vehicles may therefore want to review data from individual bridge operators, border state governments, or the Mexican and Canadian governments."

Hazardous Materials Emergency Preparedness Grants Program: Assessment of the Alignment between Local Activities and Program Goals

Show summary Open resource [pdf] (open full abstract)
"The Hazardous Materials Emergency Preparedness (HMEP) Grants Program provides technical and financial assistance to states, territories, and Indian tribes and their subdivisions to prepare and train for hazardous materials incidents. In the 2005 budget cycle, the Office of Management and Budget reviewed the program using the Program Assessment Rating Tool (PART). The PART review found that HMEP-supported local activities may be insufficiently linked to the Department of Transportation's long-term hazmat incident goal, and that the program lacks independent evaluations to identify potential areas for improvement. This report has been commissioned as a first step in determining the extent of the links between the HMEP Grants Program and the DOT hazardous materials program, and in identifying opportunities to strengthen these links. It presents findings from an assessment of the linkages between Departmental goals and funded local activities. The assessment draws on a 'logic model' that was developed to illustrate the workings of the program, as well as a review of actual grantee activities based on documentation and interviews with a subset of 16 grantees. Information from the interviews has also been compiled to present a comparison of grantees' approaches to program management, including aspects of the sub-grant and prioritization process, recordkeeping, and statelocal communication. The final section of the report draws on these findings to present a set of recommendations on effective practices for improving the alignment between grantee activities and program goals."

Decade of Decline in Person Crossings from Mexico and Canada into the United States

Show summary Open resource [pdf] (open full abstract)
"The number of persons crossing into the United States through its ports of entry along the Canadian and Mexican borders has been declining since 2000. Recently, research¬ers have proposed various reasons for the decline in per¬son crossings, including (but not limited to) the economies of the three nations and increased security at the borders. This report does not examine reasons for the decline in person crossings, rather the trends in person crossings by mode are investigated. In 2009, there were approximately 252 million person crossings into the United States from Mexico and Canada. The majority of those crossings (75 percent) took place along the Mexican border. Along both the northern and southern borders, a large proportion of crossings were with personal vehicles. An additional 17 percent of total crossings were by pedestrians."

Statewide Systems Implementation Experience from iFlorida Model Deployment

Show summary Open resource [pdf] (open full abstract)
"The iFlorida Model Deployment, which was started in May 2003, called for the Florida Department of Transportation (FDOT) District 5 (D5) to complete the design, build, and integration of the infrastructure required to support operations in 2 years. The required infrastructure was extensive, spanned numerous stakeholders, and included many technologies that were new to FDOT D5, such as sophisticated traffic management center (TMC) operations software, a wireless network deployed along I4, an interface to Florida Highway Patrol Computer Aided Dispatch (FHP CAD) data, statewide traffic monitoring, and many others. The iFlorida plans also called for deployment of these technologies in ways that required coordination among more than 20 stakeholders. It was an ambitious plan that would result in dramatically different traffic management operations for FDOT D5 and other transportation stakeholders in the Orlando area. In implementing the iFlorida plan, FDOT faced many challenges ranging from higher failure rates than expected for some field hardware to difficulties with the Condition Reporting System (CRS) and Central Florida Data Warehouse (CFDW) software. 'Despite these challenges, it can be readily claimed that the overall iFlorida Model Deployment was successful,' according to the final evaluation report for the iFlorida Model Deployment, published in January 2009. The difficulties associated with the iFlorida Model Deployment provided many opportunities to identify lessons learned from the experiences they had. The most important of these are presented below in a series of lessons learned articles."

Estimated Impacts of Septmber 11th on US Travel

Show summary Open resource [pdf] (open full abstract)
"The terrorist attacks of September 11, 2001, had an immediate and visible impact on U.S. transportation. While the obvious impacts were temporary, there may have been less obvious yet longer lasting changes in U.S. travel patterns. The Research and Innovative Technology Administration's Bureau of Transportation Statistics analyzed the impacts in three different ways. All three analyses found these post-9/11 travel trends: 1) Immediate and continuing impact in air travel 2) Immediate but temporary decline in highway travel 3) No impact on rail travel, and 4) Travelers switched from air to highway. 1. NHTS Data: A comparison of 2001-2002 National Household Travel Survey (NHTS) long-distance travel data for pre-9/11 and post-9/11 yielded the following initial findings: 1) Reduction in the amount of long-distance travel 2) Decrease in the rate of international trip taking 3) Reduction in the rate of personal business travel, and 4) Changes in mode of travel depending on distance traveled. 2. Time Series Analysis: Forecasts using travel data from 1990 to 2001 were compared to what actually took place after 9/11. The comparisons found: Actual Airline Revenue Passenger-Miles began in December 2004 to approach the forecasted values. Otherwise, up to then, Airline Revenue Passenger- Miles were significantly lower than forecast."
