Petaling Jaya and Subang Jaya's urban plans are comparable to those of Shah Alam, with one notable exception: Shah Alam isn't called the city of roundabouts for nothing. From section 1 to section 25, there are 18 roundabouts dispersed around the area that link the main thoroughfares. Plaza Alam Sentral, also known as PAS, SACC Mall, Plaza Shah Alam, formerly known as Shah Alam Mall, formerly known as Plaza Masalam, Ole-Ole Seksyen 18, Anggerik Mall, and Kompleks PKNS are some of the retail centres in the city.
