Pedestrian approach to equine hybridisation (5,8)

Ross

I believe the answer is:

zebra crossing

I'm a little stuck... Click here to teach me more about this clue!

'pedestrian approach' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
I also know that 'pedestrian' relates to this answer.

'equine hybridisation' is the wordplay.
'equine' becomes 'zebra' (zebra is a kind of equine).
'hybridisation' becomes 'crossing' (synonyms).
'zebra'+'crossing'='ZEBRA CROSSING'

'to' acts as a link.

Can you help me to learn more?

(Other definitions for zebra crossing that I've seen before include "Where traffic stops for pedestrians" , "Marked place for pedestrians to traverse road" , "Equine interbreeding" , "Marked place for traversing road" , "road safety device" .)
