Kwiminyaka yakutshanje, ngophuhliso loqoqosho, ishishini kuhola wendlela welizwe lam liqhubele phambili ngokuxhumaxhuma, nto leyo inyuse isantya sokuqhuba ukuya kuthi ga kwinqanaba elithile.Kule meko, ubume bendlela egudileyo itsala umdla kuzo zonke iinkalo zobomi. Njengesalathiso sobuchwephesha, tyaba komphezulu wendlela uhlala usetyenziselwa ukulinganisa umgangatho kunye nenqanaba lenkonzo yendlela yobunjineli bendlela. Ngexesha lenkonzo yohola wendlela, esi salathisi sibonisa ngokuthe ngqo ukhuseleko kunye nokhuseleko ezindleleni. Zininzi izinto ezichaphazela ukuthambeka kwepavityi yekhonkrithi yekhonkrithi, kubandakanya ukuthambeka kwezinto kunye nokufana komxube, ubungqongqo besingqimba sesiseko kunye nolwaleko olusisiseko, njl. Ulawulo lokwakha isiseko kunye nomphezulu yeyona inzima. Yonke ikhonkco ukusuka ekungeneni kwezixhobo ukuya ekuxubeni kwemixube ye-asphalt, ukusuka kwindledlana eya kulwakhiwo, ichaphazela ngokuthe ngqo kwaye ithintela ukuguda komphezulu wendlela. Ngexesha lenkqubo yokwakha, ukuba kukho ingxaki kwikhonkco elithile, iya kuchaphazela ukuguda komphezulu wendlela.
