BRT is a fully segregated bus lane with boarding and ticketing procedure similar to LRT.

Such concept has been used in Jakarta, Seoul, Johannesburg, Cape Town.

Some parts of the Sunway BRT will be elevated.

The problem with LRT to Sunway is that there is large flyover which blocks the construction at suitable gradient.

Besides, the Bandar Sunway taskforce did say if no LRT, then BRT is the next best thing.

Do not worry on BRT, because it has almost similar service level to LRT. Only BRT buses for BRT line, as well as same ticketing system as LRT/MRT.

Again, I doubt you can run LRT to Icon City because it is so build up. Glenmarie is easier because running through Subang Airport road has gentle curve.

Another thing is as the extension runs from Lembah Subang depot, building the line towards LDP to Icon City is very unlikely, due to the lack of available space.

For Icon City, the solution is simple. Build a proper walkway to KTM Setia Jaya.

For someone to use Sunway BRT, wanting to travel to KL. The fastest is the person to take BRT to BRT station next to KTM Setia Jaya. Then from there take KTM Komuter to KL Sentral.
