Reconstruction of the LTAIdentity font, a Humanistic sans-serif font that is commonly found in Singapore's public transport graphics.

No. The individual glyphs' outlines should be pretty close, along with its metrics such as the baseline, x-height and cap height. However, the letter-spacing (leading/tracking/kerning) varies significantly as I do not know of any techniques to create a close match. Instead, this font was optically spaced, then manually adjusted by hand. The above overlay shows this font (in pink) over an existing signage, highlighting the spacing variations.
Please let me know if there are better approaches to this issue.
