Parizvino, marambi emumugwagwa matsvuku, magirini uye eyero. Tsvuku zvinoreva kumira, girini zvinoreva kuenda, yero zvinoreva kumirira (kureva kugadzirira). Asi kare kare, kwaingova nemavara maviri chete: matsvuku negirini. Sezvo mutemo wekugadzirisa traffic wakawedzera kukwana, rumwe ruvara rwakawedzerwa gare gare, yero; Zvadaro rimwe rambi remumugwagwa rakawedzerwa. Pamusoro pezvo, kuwedzera kweruvara kwakabatana zvakanyanya nemaitiro evanhu epfungwa uye chimiro chekuona.
Retina yemunhu ine masero ephotoreceptor akaita setsvimbo uye marudzi matatu emasero ephotoreceptor akaita sekoni. Masero ephotoreceptor akaita setsvimbo anonyanya kunzwa chiedza chechero, nepo marudzi matatu emasero ephotoreceptor akaita sekoni anonzwa chiedza chitsvuku, chiedza chegirini nechiedza chebhuruu zvichiteerana. Pamusoro pezvo, chimiro chekuona chevanhu chinoita kuti zvive nyore kuti vanhu vasiyanise pakati petsvuku negirini. Kunyangwe yero nebhuruu zvisiri zvakaoma kusiyanisa, nekuti masero ephotoreceptor ari muziso haanyanyi kunzwa chiedza chebhuruu, tsvuku negirini zvinosarudzwa semavara emwenje.
Kana iri nzvimbo yeruvara rwemwenje yemumugwagwa, pane chikonzero chakasimba, kureva kuti, zvichienderana nepfungwa ye physical optics, mwenje mutsvuku une wavelength yakareba uye transmission yakasimba, iyo inokwezva kupfuura mamwe masaini. Saka, yakaiswa seruvara rwechiratidzo chemumugwagwa kune traffic. Kana iri yekushandiswa kwegirini seruvara rwechiratidzo chemumugwagwa, imhaka yekuti musiyano uripo pakati pegirini netsvuku wakakura uye zviri nyore kusiyanisa, uye coefficient yemavara maviri aya yakaderera.
Pamusoro pezvo, kune zvimwe zvinhu kunze kwezvikonzero zviri pamusoro apa. Nekuti ruvara pacharwo rune kukosha kwekufananidzira, zvinoreva ruvara rwega rwega zvine hunhu hwarwo. Semuenzaniso, ruvara rutsvuku runopa vanhu chido chakasimba kana kunzwa kwakanyanya, zvichiteverwa neyero. Zvinoita kuti vanhu vanzwe vakangwarira. Nokudaro, zvinogona kuiswa semavara emwenje yemotokari dzvuku neyero ine zvinoreva kurambidza traffic nenjodzi. Girini zvinoreva kunyorova uye kunyarara.
Uye ruvara rwegirini runoderedza kuneta kwemaziso. Kana ukaverenga mabhuku kana kutamba pakombiyuta kwenguva yakareba, maziso ako achanzwa kuneta kana kuti kuomesa musoro zvishoma. Panguva ino, kana ukatarira zvirimwa kana zvinhu zvakasvibirira, maziso ako achanzwa kunyaradzwa kusingatarisirwi. Saka, zvakakodzera kushandisa ruvara rwegirini seruvara rwechiratidzo chemugwagwa chine kukosha kwemugwagwa.
Sezvambotaurwa pamusoro apa, ruvara rwechiratidzo chemotokari rwepakutanga haruna kuiswa zvisina kurongeka, uye pane chikonzero chakati. Nokudaro, vanhu vanoshandisa ruvara rutsvuku (runomiririra njodzi), yero (runomiririra yambiro yekutanga) uye girini (runomiririra kuchengetedzeka) semavara ezviratidzo zvemotokari. Iye zvino zviri kuramba zvichienderera mberi nekushandisa uye kufambira mberi kune sisitimu iri nani yekuraira traffic.
