Kutheni iibollards zaseOstreliya zikhetha umthubi?

Iibhola zaseOstreliya zikhetha umthubi ngezi zizathu zilandelayo:

1. Ukubonakala okuphezulu

Umthubi ngumbala otsala amehlo kakhulu onokubonwa lula ngabantu kunye nabaqhubi kuzo zonke iimeko zemozulu (ezifana nokukhanya kwelanga okunamandla, iintsuku ezinamafu, imvula kunye nenkungu) kunye neendawo ezikhanyayo (imini / ubusuku).

Umbala otyheli ubonakala kakhulu emehlweni omntu, okwesibini kuphela kumhlophe.

Ebusuku, ngezixhobo ezikhanyayo, umthubi ubonakala kakhulu kukukhanya kwemoto.

2. Ukudlulisa ulwazi olulumkisayo

Umthubi udla ngokusetyenziswa njengombala wesilumkiso kwindawo yezothutho kunye nokhuseleko ukukhumbuza abantu ngeengozi ezinokubakho okanye imiqobo.

Indawo efana neempawu zendlela, izithinteli zesantya, kunye nemicu yokulumkisa nayo isebenzisa tyheli.

Umsebenzi weiibholadiikholisa ukuthintela ukungqubana kunye nokuthintela izithuthi ukuba zingangeni ngempazamo kwiindawo zabahambi ngeenyawo, ngoko ke ukuthelekisana kombala kudla ngokusebenzisa imibala enentsingiselo "yesilumkiso".

3. Ukuthotyelwa kwemigangatho kunye neenkcukacha

I-Australia inoluhlu lwemigangatho yoyilo lwendlela kunye nocwangciso lwedolophu, njenge-AS 1742 (i-traffic control equipment series standard), ecebisa ukusetyenziswa kwemibala eqaqambileyo ukuphucula ukhuseleko.

Iibhola ezityhelizinochaso olumandla kumhlaba kunye nemvelaphi (enje ngepavumente engwevu, indawo eluhlaza, neendonga), eziququzelela ulawulo olusemgangathweni.

4. Enxulumene nenjongo

Imibala eyahlukeneyo inemisebenzi eyahlukeneyo:
Mthubi: iqhele ukusetyenziswa kwizilumkiso zendlela kunye nothintelo lokuntlitheka kokhuseleko.
Umnyama okanye igrey: ifanelekile ngakumbi kwiibollards zokuhlobisa.
Ubomvu nomhlophe: inokusetyenziselwa ukubekwa wedwa okwethutyana okanye ulawulo lwexeshana.

Ukuba ubonaiibhodi ezityhelikwizitrato zaseOstreliya, kwiipaki, ezikolweni, kudederhu lweevenkile okanye kwiindawo zokupaka, basenokuba:
Umsebenzi wokhuseleko lokhuseleko (ungquzulwano lwemoto)
Umsebenzi wokwahlula indawo (njengezowuni yokungangeni)
Umsebenzi wesikhokelo esibonakalayo (isikhokelo sendlela yendlela)
