Starting from the early 1990s, Kuala Lumpur experience considerable development since the Asian Economic Boom of the early 1990s (when economic growth was averaging at 10%). Under the initiative the Prime Minister Mahathir Mohamad at globalisation, major urban developments in the Klang Valley has resulted in an extended Kuala Lumpur Metropolitan Area. This area, which extends from the Federal Territory of Kuala Lumpur westward to Port Klang, east to the Titiwangsa Mountains as well as to the north and south and includes other administratively separate towns and cities such as Klang, Shah Alam, Putrajaya and others, is known as Greater Kuala Lumpur. Notable projects undertaken within Kuala Lumpur itself include the development of a new Kuala Lumpur City Centre around Jalan Ampang. Skyscrapers have shot up and Kuala Lumpur, formerly a languid colonial outpost, has become one of the most lively, advanced and vibrant cities in South East Asia. Traffic jams are a scourge commuters endure daily, despite the numerous 6-lane highways constructed all over the city (including two elevated highways). Bus services are notoriously irregular and inadequate.
