Focus on Low-Speed Electric Vehicle Noise: Should There Be Sound?

Ezinsukwini zakamuva, udaba lomsindo olwenziwe nguizimoto zikagesi eziphansiSekuyiphuzu lokugxila, kuphakamisa imibuzo yokuthi lezi zimoto kufanele zikhiqize imisindo ezwakalayo. I-US National Highway Traffic Safety Administration (NHTSA) isanda kukhiphe isitatimende sezimoto zikagesi ezinesivinini esiphansi, zikhanyisa ukunaka kakhulu emphakathini. I-ejensi isho ukuthi izimoto zikagesi eziphansi kufanele zikhiqize umsindo olwanele ngenkathi zihamba ukuze zikwazise abahamba ngezinyawo nabanye abasebenzisi bomgwaqo. Lesi sitatimende siye sakhipha isibonakaliso esijulile ekuphepheni nasekuhambeni kwezimoto kwezimoto zikagesi ezinesivinini esiphansi ezindaweni zasemadolobheni.

Gxila kumsindo wemoto kagesi ephansi uma kufanele kube nomsindo - i-cyclemix

Lapho uhamba ngejubane elingaphansi kwamakhilomitha angama-30 ngehora (amamayela ayi-19 ngehora), umsindo wenjini yezimoto zikagesi uphansi, futhi kwezinye izikhathi, cishe akunakubalulekanga. Lokhu kubeka ingozi engaba khona, ikakhulukazi ngenxa "yabantu abayizimpumputhe, abahamba ngezinyawo abanombono ojwayelekile, kanye nabahamba ngamabhayisekili." Ngenxa yalokho, i-NHTSA ikhuthaza abakhiqizi bezimoto zikagesi ukuthi bacabangele ukwamukela umsindo ohlukile ngesikhathi sesigaba sokuklama ukuze baqinisekise ukuqaphela okusebenzayo kwabahamba ngezinyawo abazungezile lapho beshayela ngejubane eliphansi.

Ukusebenza buthule kweizimoto zikagesi eziphansiUthole amanani abalulekile emvelo, kepha futhi waveza uchungechunge lokukhathazeka okuhlobene nokuphepha. Abanye ochwepheshe bathi ezindlekweni zasemadolobheni, ikakhulukazi emigwaqweni enabantu abaningi, izimoto zikagesi eziphansi ezingenamsindo owanele ukuxwayisa abahamba ngezinyawo, ukwandisa ubungozi bokushayisana okungalindelekile. Ngakho-ke, ukuncoma kweNHTSA kubonakala njengokuthuthuka okuhlosiwe okuhloswe ngawo ukuthuthukisa ukubonakala kwezimoto zikagesi eziphansi ngesikhathi sokusebenza ngaphandle kokuyekethisa ukusebenza kwawo kwezemvelo.

Kuyaphawuleka ukuthi abanye abakhiqizi bezimoto abasezingeni eliphansi kagesi sebevele baqala ukubhekana nalolu daba ngokufaka izinhlelo eziklanyelwe ngokukhethekile ezinhlelweni ezintsha. Lezi zinhlelo zihlose ukulingisa imisindo yenjini yezimoto zendabuko kaphethiloli, okwenza izimoto zikagesi ezinesivinini esiphansi zibonakale ngenkathi zihamba. Lesi sixazululo esisha sinikeza ungqimba owengeziwe wokuphepha kwezimoto zikagesi e-Urban Traffic.

Kodwa-ke, kukhona nabagxeki abangabaza izincomo ze-NHTSA. Abanye bathi isimo esithule sezimoto zikagesi, ikakhulukazi ngejubane eliphansi, kungenye yezinto zabo ezikhangayo kubathengi, futhi kwethulwa umsindo ngocingo kungahlehlisa isimo lesi sici. Ngakho-ke, ukushaya ibhalansi phakathi kokuqinisekisa ukuphepha kwabahamba ngezinyawo kanye nokugcina izimfanelo zezemvelo zezimoto zikagesi zihlala kuyinselelo ephuthumayo.

Ekuphetheni, udaba lomsindo kusukaizimoto zikagesi eziphansiunaka ukunakwa okugcwele emphakathini. Njengoba izimoto zikagesi ziqhubeka nokuthandwa, ukuthola isixazululo esiqinisekisa ukuphepha kwabahamba ngezinyawo ngenkathi kugcinwa izici zabo zezemvelo kuzoba yinselele eyabiwe kubakhiqizi kanye nezinhlaka zokulawula zikahulumeni. Mhlawumbe ikusasa lizofakaza ukusetshenziswa kobuchwepheshe obusha ukuthola isixazululo esifanele esivikela abahamba ngezinyawo ngaphandle kokuyekethisa isimo sezimoto zikagesi.
