Scientific - technical translation Some things we should learn about roundabouts Richard Webb rightly extols the virtues of roundabouts and identifies problems implementing them in the US. There is also great scope for improvement on the way they laid out in the U. I do suspect that our Department of Transport may be as intransigent as the US authorities. I am thinking of a Swiss design that allows safe, low-speed entry and exit in all traffic conditions for all vehicles, including articulated bendy buses, with high traffic flows. This is achieved by slight curves to the arms, each a single carriageway just wide enough for bus wheels. Yellow zebra pedestrian crossings on each arm remind drivers that they don’t have priority under Swiss law and offer easy and safe passage for walkers and cyclists. In the UK, anyone crossing the arm of a roundabout is likely to be intimidated by speeding drivers, in part because it unnecessarily has two lanes. All parties in the UK’s recent election promised to promote cycling and walking for health and climate advantage. That will be impossible unless we learn from the Swiss, not only on roundabouts, but more generally on road and path design.
Aylanma yo’llar haqida biz bilishimiz kerak bo’lgan ma’lumotlar Robert Veb aylanma yo’llarning afzalliklarini to’g’ri talqin qiladi va AQSh da ular keltirib chiqarayotgan muammolarni tasniflab beradi. BB hududida ularni joriy etishni rivojlantirish uchun katta imkoniyat mavjud. Bizning Transport Departamenitimiz AQSh hukumatidek murosa qilish tarafdori ekanligigga shubham bor. Menimcha, Shvetsariya loyihasi xavfsiz hamda ulkan tirbandlik oqimida barcha transport vositalari, hatto bukiluvchan avtobuslar uchun ham barcha sharoitlarga ega hisoblanadi. Bunga har biri avtobuslar uchun yetarlicha kenglikda bo’lgan harakat yo’llarini biroz egri qilish orqali amalga oshirildi. Har bir harakatlanish yo’lidagi sariq zebrali piyodalar harakatlanish yo’lakchasi haydovchilarga Shvetsariya qonunlariga ko’ra ularning piyodalar va velosiped haydovchilaridan ustun emasligi va ular harakatlanadigan yo’lakni xavfsiz tutishlarini eslatib turadi. BB da aylanma yo’lning biror tomonidan kesib o’tayotgan kishi tezlikni oshirgan haydovchi sabab asabiylashishi mumkin, chunki bu ba’zan har ikki tomonda sodir bo’lishi mumkin. BB ning so’nggi saylovida barcha partiyalar sog’liq hamda ob-havo masalalari uchun piyoda yurish va velosiped haydashni keng yo’lga qo’yishga va’da bergan edi. Biz Shvetsariyaning faqatgina aylanma yo’llar haqidagi emas, balki umumiy yo’l va yo’lakchalar dizayni haqidagi qonunlariga amal qilmasak, bu ilojsiz bo’lib qolishi mumkin. What more can the aviation industry do? What more could the aviation industry do to reduce carbon emissions? The decision by Airbus to stop making the double-decker A380 in 2021 may need to be reviewed. This plane, particularly if configured with all seats in economy for intercontinental travel, has higher efficiency in terms fuel used per passenger per kilometer than others. Incorporating railway stations into more airport passenger terminals would help reverse the current trend of scheduling hundreds of flights between regional airports, which may be convenient, but is more unkind to the environment than doing a final leg by train. A jet engine’s maximum efficiency is at high throttle settings. So can we design a plane with booster engines used only for take-off, with more modest engines for cruising flight? Running big engines for the entire flight is an absurd waste of kerosene and an abuse of the atmosphere. Clearly a new design of aircraft would be needed to stop the drag of extra engines ruining the economy gains of the concept.
Aviatsiya sanoati yana nimalar qilishi mumkin? Zaharli gazlarni kamaytirish uchun aviatsiya sanoatida yana nimalar qilishimiz mumkin. 2021- yilda A380 nomli ikki qavatli avtobus shaklidagi samolyotlarni ishlab chiqarishni to’xtatish uchun Airbus kompaniyasi qabul qilgan qaror ko’rib chiqilishi kerak. Qit’alararo sayohat uchun ekonom klassi to’liq o’rindiqlar bilan jihozlangan ushbu samolyotning har kilometga bir yo’lovchi uchun sarflaydigan yonilg’isi boshqa samolyotlarga qaraganda ancha kam hisoblanadi. Aeroportning yo’lovchilar tushadigan bekatlarini temiryo’l stansiyalari bilan bog’lash hududiy aeroportlar orasidagi qatnov jadvalining yaxshilanishiga yordam berishi mumkin, bu ancha qulay, ammo bu atrof-muhit uchun ancha zararli bo’lishi mumkin. Qo’shimcha motor eng ko’p yonilg’i sarflanishini nazorat qiluvchi qismga ta’sir etadi. Shunday ekan biz samolyotlarni faqat uchish uchun qo’llaniladigan kuchlantiruvchi motor, yoki sayohat uchun mo’ljallangan uncha katta bo’lmagan motor bilan loyihalashimiz mumkinmi? Butun sayohat uchun katta motorlardan foydalanish atmosferaga ziyon yetkazish va yonilg’ini bekorga sarflash hisoblanadi. Havo kemalarining yangi loyihasi iqtisodga zarar bo’luvchi qo’shimcha motorlardan foydalanishni to’xtatishga xizmat qiladi. Download 29.81 Kb. Do'stlaringiz bilan baham: |
