In attempt to promote racial harmony and to balance racial mix within public housing estates, the Ethnic Integration Policy was introduced in March 1989. This policy is concern with maintaining prescribed block and neighbourhood proportions in each ethnic group. Resale of flats to a particular ethnic group is restricted if it increases the proportion of the affected ethnic group beyond the prescribed limit in the block or neighbourhood. However, no restriction is imposed on sellers and buyers from the same ethnic group as it will not further increase the ethnic group's proportion in the block or neighbourhood. This policy is applied consistently to all ethnic groups.

Singapore’s Transportation
Singapore has one of the world best transportation service in the world. The main public transports are the Mass Rapid Transit (MRT), Light Rail Transit (LRT) and Public Bus Services.
Although Singapore transportation modes prove effective for fellow, we did not stop but continue to improve the efficiency for our transportation to a higher level. With this in mind, we have created 2 amazing technology in for our transportation need.
This first is the Electronic Road Pricing System (ERP). We are the first in the world to use Radio Frequency ID technology to effectively track and manage road traffic volume at different times of the day. This traffic management tool is an electronic toll system that deducts prescribed road price from a stored value smart card inserted in a Radio Frequency ID based in-vehicle unit.
The other is the ez-link card. It is a new-generation stored value contactless smart card that communicates with the ez-link reader using radio wave via wireless communication. According to www.ezlink.com.sg, this card improves boarding time for buses by as much as 50% and allows 40 people to pass through the MRT fare gantry using the ez-link card for same time that it takes 25 people to pass through using the old payment mode.
