Sadak par jagah ka hisaab: gaadi gino ya log?
Sadak par 20 car khadi hon, har car mein sirf ek aadmi. Aur ek bus mein 40 log. Kisne sadak ka zyada achha istemaal kiya?
Socho pehle… phir dekho jawab
Bus ne! Car mein jagah zyada, log kam. Bus mein jagah kam, log zyada. Engineer is hisaab ko 'log gino, gaadiyan nahi' kehte hain.
Sadak ki jagah seemit hoti hai. Agar har aadmi alag gaadi mein chale, toh sadak jaldi bhar jaati hai aur jam lag jaata hai. Socho, school ki chhutti ke baad gate par kitni bheed hoti hai!
Cause-effect: zyada log bus ya metro mein chalein, toh sadak par gaadiyan kam, jam kam aur dhuaan bhi kam. Isliye shehar ki planning mein bus aur paidal raaste zaroori hain.
Desh ke pehle National Household Travel Survey ne bataya ki kaam par jaane wale lagbhag 43% log two-wheeler se jaate hain, 28% paidal, aur sirf lagbhag 7% bus se. Shehron mein auraten aadmiyon se kai guna zyada bus use karti hain. Isliye achhi aur baar-baar aane wali bus bahut logon ki madad karti hai.
Ghar pe try karo
Kaagaz par ek lambi sadak banao. 10 chhote dibbe (car) kaato, har ek mein ek bindu (aadmi). Ek lamba dabba (bus) kaato jisme 10 bindu. Dono ko sadak par rakho. Kisne kam jagah li?
Wow!
Ek bus ka kaam bahut saari car mil kar karti hain, aur woh bhi zyada jagah lekar!
Mummy-Papa ke liye
Aaj bachche ke saath kaagaz ki sadak par car aur bus ke tukde rakh kar dekhiye ki kisme kam jagah lagti hai.
