Isokron karta

En isokron karta (eller diagram) i geografi och stadsplanering är en karta som kopplar områden till isokroner mellan olika punkter. En sådan karta kallas ibland en isokron (iso = lika, krona = tid). ^[1] I hydrologi och trafikplanerings används isokron kartor för att visa områden med lika lång tid. Termen används också i kardiologi. ^[2] ^[3] ^[4]^[5]

Användning redigera

Transportplanering redigera

En gammal isokron karta över Melbourne som visar resetider i järnvägssystemet , 1910-1922

Isokron kartor används i transportplanering för att visa tillgänglighet i transportsystemet där restid används som kostnaden. Dessa kartor kan skapas för olika transportmedel ^[6] som till exempel: fot, cykel och bil.
