I remeber the day when i first visited melbourne...my friend told me, its easy to walk in Melbourne city..you will not get lost easily because the city is planned in a grid formation...

this has suddenly make me remember the middle ring road in Malaysia...yes, we have the same concept, a ring that goes around our city...

My father's friend, Lim told me that in Guangzhou there are only 2 rings currently but the most ring in the country is in Beijing..they have 6 rings together...Amazing....in a sudden i feel that the basic shape is so interesting....it can be apply to our urban city and assist us to walk in the city easily...and especially it can avoid traffic jam too...is just that we might need to drive long er distance...

I think the ring is indicating the speed of the development or can be said the time taken for development, just like the xylem in the plants...it will develop more rings when it gets older...
all this ring is connected with different exit, in every quarter of the ring, it can form a town, perhaps with grid line planing..

Chicago map..marvelous!
