TRB’s Airport Cooperative Research Program (ACRP) Research Report 163: Guidebook for Preparing and Using Airport Design Day Flight Schedules explores the preparation and use of airport design day flight schedules (DDFS) for operations, planning, and development. The guidebook is geared towards airport leaders to help provide an understanding of DDFS and their uses, and provides detailed information for airport staff and consultants on how to prepare one.

Introduction of unmanned aircraft systems (UAS) will pose safety, economic, operational, regulatory, community, environmental, and infrastructure challenges to airports. These risks are further complicated by the dynamic nature of UAS technological development. Experiences and lessons learned from recent major aviation system changes demonstrate the critical importance of ensuring that airports have the resources needed to avoid adverse impacts and maximize benefits as early as possible. This pre-publica...

Airports in the United States are responding to the demand for increased air travel with sustainable development that incorporates more energy-efficient and lower-emission technologies. Funding for greenhouse gas (GHG) emissions-reducing technologies, such as electrification, alternative fuels, and renewable energy, has also become more accessible as technologies are proven to be safe, reliable, and cost-effective. Newer strategies and programs to reduce GHG emissions reach beyond airport operations to i...

With large swaths of the country still stifling under quarantine from the COVID-19 pandemic, more people than ever are supplementing their meager IRL social interactions with online alternatives. But but doing so can become a proverbial minefield wit...

Whatever you think of Doom Eternal right now, id and Bethesda are determined to spice it up going forward. They’ve hinted at what’s coming next for the hellish shooter, starting with a preview of the game’s first free update. The simply titled Update...

Susan Heap, the Director of Operations at Ferrovial Services says that "Transportation is meaningful across all societies, for many different reasons. I chose a career that connected me to things that matter to all of us. I stay in this industry because of the variety of people and projects that I get to work with every day. There is always a new challenge to overcome or skill-set to learn." Thank you Susan for participating in TRB's Centennial Celebration. To read the more than 60 responses to April's q...

As all aspects of transportation deal with the unfolding effects of the COVID-19 pandemic, there are research needs, gaps, and potential ways to leverage innovation revealing themselves across all modes, systems, and disciplines in transportation. In keeping with the mission of the National Academies of Sciences, Engineering, and Medicine to provide trusted, timely, impartial, and evidence-based information exchange and research, TRB is issuing an urgent and directed call for Research Needs Statements sp...

Accelerated bridge construction (ABC) utilizes rigorous planning, new technologies, and improved methods to expedite construction. Prefabricated columns and their connections to adjoining bridge members (cap beams, footings, pile caps, and pile shafts) are the most critical components of ABC in moderate- and high-seismic regions. The TRB National Cooperative Highway Research Program's NCHRP Research Report 935: Proposed AASHTO Seismic Specifications for ABC Column Connections develops AASHTO specificatio...

Standing Technical Committee on Critical Transportation Infrastructure got its start as the Task Force on Critical Transportation Infrastructure Security tied directly in response to the Presidential Decision Directive 63, Critical Infrastructure Protection (PPD-63). Soon after the task force was established, as a way to bring awareness to this topic, TRB published a special edition of TR News (211): Transportation Security: Protecting the System from Attack and Theft (November-December 2000). The editio...

Pletení, to přece není práce pro chlapa, řeknete si. Ovšem ve slovenských Čičmanech (a vůbec v celé oblasti Horního Pováží) by mnozí nesouhlasili. Tady bývalo pletení ponožek z ovčí vlny výsostnou činností tamních bačů. V dnešní době je ovšem takový pletač nadmíru vzácný.

Seriál „Byl jednou jeden život“ zná snad každý pod 40 let. V německé verzi tohoto populárního seriálu pro děti hodné bílé krvinky zabíjejí plynem zlé bakterie, které volají „To je hrůza!“. Volají to v židovském jazyku jidiš. Jazykové mutace v jiných zemích tento výkřik neobsahují a neobsahuje ho ani originální francouzská verze. To si toho opravdu za 35 let vysílání seriálu v Německu nikdo nevšiml? Nebo se nad tím jen dobře bavili? Na antisemitskou narážku upozornil nyní článek na německém webu zabývajícím se médii Übermedien.de.

Někteří badatelé tvrdí, že dějiny Židů v Číně začínají již v 6. století před naším letopočtem za dynastie Čou, k tomu však nejsou žádné archeologické či jiné materiální důkazy. Všeobecně se tak počítají počátky židovské přítomnosti až od 8. století našeho letopočtu, za vlády dynastie Tang, kdy do Říše středu dorazily první skupinky obchodníků po Hedvábné stezce a usazovali se podél ní. Dnes od 18 hodin můžete na Facebooku Reflexu sledovat premiéru speciálního hudebního pořadu Židé v říši středu. Dějiny izraleského národa a Číny jsou zajímavě propojené.

Zdá se, že pandemie COVID 19 ustupuje. Lidem otrnulo a už se objevují logické otázky, kdo zaplatí vzniklé škody nejen podnikatelům, ale i dalším subjektům. Paleta poškozených se stále rozšiřuje a není skoro hodiny, aby v mediích nevystoupil někdo z poškozených láteřící, že na něj vláda zapomněla anebo že pomoc přichází pomalu. Někdy oprávněně, někdy spíše vykutáleně.

Charles Burns je magorický komiksový génius, jehož knihy vás nenechají chladnými. Někomu mohou být odporné, jiný se v nich bude blaženě pitvat a snažit se o interpretaci autorových výpotků. Je pravda, že podivnost se v jeho komiksech stupňuje. Teď máme jako druzí na světě – dříve než Američané a Britové – možnost pohroužit se do prvního dílu jeho nové trilogie.

Bojíte se, že letos nebudete zatlačovat slzu u zlatavých nekonečných obzorů? Ale budete. A mnozí alergici na řepku slzy zatlačují už teď. Rajčata stojí sice 170kč za kilo, květák je už také kaviárem českých domácností, ale heslo "řídit stát jako zemědělství" nám zajistilo širé moře zlaté barvy. Sice se z řepky nenajíme (teda až na ty, co z pěstování rýžují zlaté dotace), ale že jsou to panorámata, co? 

Ve věku 87 let dnes zemřel jeden z otců zakladatelů rock´n´rollu Little Richard (vlastním jménem Richard Wayne Penniman). S odvoláním na jeho syna to na svém webu napsal časopis Rolling Stone. Příčina smrti zpěváka a klavíristy z amerického státu Georgia zatím není známá.

"America's Funniest Home Videos" will resume the remainder of season 30 the following week at 7:00/6:00c.

Since the outbreak of COVID-19, face masks have been in high demand. One company decided to take an eco-friendly approach to manufacturing and supplying the public with protective masks. The Professional Association of Diving Instructors (PADI) partnered with the sustainable sportswear company Rash’r to turn plastic pollution found in the ocean into face masks.

All proceeds from the masks go directly back into the manufacturing of more masks to help recycle plastics from the ocean. The masks feature a number of ocean-themed designs and include special sizes for kids. The company has received more than 15,000 mask pre-orders in just a few weeks—which has helped recycle more than 1,300 pounds (590 kg) of ocean pollution. The U.S. Centers for Disease Control and Prevention (CDC) now recommends that people wear cloth face masks to prevent the spread of COVID-19 in public places. The masks made by PADI offer a sustainable alternative to the N95 respirator masks being reserved for health care workers.
