The Breach of Security at San Jose’s Airport Raises Broader Issues

This Transportation Security Perspective is the fifth in a continuing series produced by the National Transportation Safety and Security Center of the Mineta Transportation Institute. These examine major terrorist attacks and trends in terrorists targeting surface transportation. Previous perspectives include the bus attack in Abuja, Nigeria, the terrorist bombings in Volgograd, Russia; the assault on passengers at the Kunming train station in China; and more

A simple model for the short-time evolution of near-surface current and temperature profiles

A simple analytical/numerical model has been developed for computing the evolution, over periods of up to a few hours, of the current and temperature profile in the upper layer of the ocean. The model is based upon conservation laws for heat and momentum, and employs an eddy diffusion parameterisation which is dependent on both the wind speed and the wind stress applied at the sea surface. Other parameters such as the bulk-skin surface temperature difference and CO$_2$ flux are determined by application of the Molecular Oceanic Boundary Layer Model (MOBLAM) of Schluessel and Soloviev. A similar model, for the current profile only, predicts a temporary increase in wave breaking intensity and decrease in wave height under conditions where the wind speed increases suddenly, such as, for example, during gusts and squalls. The model results are compared with measurements from the lagrangian Skin Depth Experimental Profiler (SkinDeEP) surface profiling instrument made during the 1999 MOCE-5 field experiment in the waters around Baja California. SkinDeEP made repeated profiles of temperature within the upper few metres of the water column. Given that no tuning was performed in the model, and that the model does not take account of stratification, the results of the model runs are in rather good agreement with the observations. The model may be suitable as an interface between time-independent models of processes very near the surface, and larger-scale three-dimensional time-dependent ocean circulation models. A straightforward extension of the model should also be suitable for making time-dependent computations of gas concentration in the near-surface layer of the ocean.Comment: 20 pages, 5 figures, 1 table.

Bus Operator Awareness Research and Development Training Program

This training is designed to enhance the abilities of bus operators to: Quickly and effectively evaluate suspicious and dangerous activities Take actions to protect yourself and your passengers, and Provide timely and accurate information to law enforcement through your control center This summary and the full instructor-led course were developed by the Transportation Security Administration (TSA) in cooperation with the National Transportation Security Center of Excellence (NTSCOE), managed through the Science and Technology Directorate of DHS. Through the intensive efforts of four universities and two federal agencies, the team conducted extensive research both nationally and abroad to identify appropriate countermeasures and related skill sets for bus operators relative to identifying suspicious and dangerous activity and reacting appropriately with a focus on life safety concerns

Carnage Interrupted: An Analysis of Fifteen Terrorist Plots against Public Surface Transportation, Research Report 11-20

This report examines 13 terrorist plots against public surface transportation that were uncovered and foiled by authorities between 1997 and 2010 and two failed attempts to carry out attacks. Certainly, this is not the total universe of foiled or failed terrorist plots in these years, but they were selected on the basis of what is known about them and the accessibility of information. The report focuses on terrorist plots in the West. Seven of the 15 plots took place in the United States, and four occurred in the United Kingdom. These two countries figure prominently as targets of terrorism, and in addition, American and British officials have dealt with terrorist plots through publicized arrests and trials, which provide additional information. Although motive was not a criterion in the selection of the plots, all but one involve individuals or groups inspired by al Qaeda’s ideology of violent global jihad against the West. The exception is the 1997 Flatbush plot, in which two terrorists, both of whom had connections with Hamas, angered by events in Palestine, simply wanted to kill as many Jews as possible to express their opposition to U.S. support for Israel. Other sources suggest that the Flatbush plotters wanted to force the release of jailed Islamist terrorists in the United States, including Ramzi Yousef, who participated in the 1993 World Trade Center bombing, and Sheik Omar Abdul-Rahman, who was convicted for his involvement in a plot to carry out additional bombings in New York

“Smashing Into Crowds” -- An Analysis of Vehicle Ramming Attacks

Vehicle ramming attacks are not new. But since 2010 Jihadists have urged their use. Is this the wave of the future, or a terrorist fad? To answer this and other questions the authors expanded and updated the database used in their May 2018 MTI Security Perspective entitled An Analysis of Vehicle Ramming as a Terrorist Threat to include 184 attacks since January 1, 1970. They also reviewed literature and examined some cases in detail. This MTI Security perspective indicates that while not new, vehicle rammings are more frequent and lethal since 2014, although the number of attacks seems to be dropping in 2019. Still it is too early to know if this is because of government countermeasures or because it is a fad that has come and gone. They also found that: (a) the majority of attacks occur in developed countries like the US and Europe; (b) though not more lethal than some other tactics they can be easily carried out by those who cannot get bombs or guns in a target-rich environment that is difficult to protect; (c) while Jihadists (responsible for only 19% of the attacks) have exhorted their use since 2010, it isn’t clear these calls have been successful -- instead the pattern of attacks suggest a kind of wider contagion; (d) attackers plowing vehicles into public gatherings and pedestrianized streets are the most lethal, particularly the attacks are planned and the drivers rent or steal large trucks or vans driven at speed; and finally, (e) government authorities cannot prevent these attacks but can and are doing things to prevent them and mitigate fatalities when they occur

A Terrorism Analysis of the April 14, 2014, Bus Terminal Bombing in Abuja, Nigeria

This Transportation Security Perspective is the fourth in a continuing series produced by the National Transportation Safety and Security Center of the Mineta Transportation Institute. These examine major terrorist attacks and trends in terrorists targeting surface transportation. Previous perspectives include the terrorist bombings in Volgograd, Russia; the assault on passengers at the Kunming train station in China; and the reported plot against the Metro in Los Angeles

Selective Screening of Rail Passengers, MTI 06-07

The threat of another major terrorist attack in the United States remains high, with the greatest danger coming from local extremists inspired by events in the Middle East. Although the United States removed the Taliban government and destroyed al Qaeda’s training camps in Afghanistan, events in Europe and elsewhere have shown that the terrorist network leadership remains determined to carry out further attacks and is capable of doing so. Therefore, the United States must systematically conduct research on terrorist strikes against transportation targets to distill lessons learned and determine the best practices for deterrence, response, and recovery. Those best practices must be taught to transportation and security professionals to provide secure surface transportation for the nation. Studying recent incidents in Europe and Asia, along with other research, will help leaders in the United States learn valuable lessons—from preventing attacks, to response and recovery, to addressing the psychological impacts of attacks to business continuity. Timely distillations of the lessons learned and best practices developed in other countries, once distributed to law enforcement, first responders, and rail- and subway-operating transit agencies, could result in the saving of American lives. This monograph focuses on the terrorist risks confronting public transportation in the United States—especially urban mass transit—and explores how different forms of passenger screening, and in particular, selective screening, can best be implemented to reduce those risks

The Terrorist Attack in Kunming, China: Does It Indicate a Growing Threat Worldwide?

At 9:00 pm on March 1, 2014, six men and two women, dressed in black and wielding knives, arrived at the Kunming train station, one of the largest in southwest China, and began slashing people at random. Before authorities could stop them, the assailants had killed 29 people and wounded another 143. It was the second worst terrorist attack in the history of the People’s Republic of China, not including a series of bombings in Shijiazhuang in 1998, which killed 108 people. These, however, were carried out for personal, not political reasons. It was also China’s second most lethal transportation attacks

Mineta Transportation Institute Says Subways Are Still in Terrorists’ Sights

The FBI arrested a California National Guard reservist on March 17 as he headed for the Canadian border on his way to Syria. Once in Syria, Nicholas Michael Teausant, who is also a student at San Joaquin Delta Community College in Stockton CA, planned to join the Islamic State of Iraq and the Levant (ISIL). Although he had never attended the army’s basic training course and was in the process of being discharged by the National Guard for failing to meet “basic education requirements,” Teausant thought he could teach the Syrian jihadists shooting skills and urban warfare tactic

By the Numbers: Russia’s Terrorists Increasingly Target Transportation

If body count is the terrorists’ goal, then surface transportation provides an attractive target— crowds of strangers in confined environments. While Umarov’s Chechen predecessors carried out spectacular hostage seizures at hospitals, a primary school, and even at a theater in the heart of Moscow, trains, subways, and buses have featured heavily among their targets
