City Hall is going to spend up to one million baht on redesigning bus route boards after the existing ones came under fire from commuters.

The move comes after images went viral on social media showing passengers squatting to read information. Other images show commuters mockingly using magnifying glasses to read the minuscule fonts on the boards.

Bangkok deputy governor Chakkaphan Phewngam pledged to solve the problem within the next three months.

"The fonts will be larger and made more colourful so that people of all ages can easily read them. We expect to spend less than a million baht redesigning 50 boards. There will be no more need to use a magnifying glass and squat just to read the bus routes," Mr Chakkaphan said Monday.

The boards in question are located in seven areas: the Mo Chit-Saphan Khwai area, Victory Monument, Rattanakosin Island, Siam Square, Sukhumvit-On Nut, Sathon Road and Wong Wian Yai-Phetkasem.

Mr Chakkaphan said it is not necessary to change all boards. Officials only need to replace the maps. However, the Bangkok Metropolitan Administration needs to dig into its coffers because the two-year warranty it had with the board maker has expired.

Some private firms and organisations have offered help by suggesting design ideas, he said.

"We would also welcome it if they would help cover expenses," Mr Chakkaphan added.

The deputy Bangkok governor also said the city will take this opportunity to modernise the boards by including QR codes which passengers can scan for additional information.
