Use tree planting within medians to create additional canopy cover, help distinguish between opposing carriageways and further narrow the perceived width of corridor.
Benefits
- Increases canopy to mitigate against urban heat island effect
- Narrows the perceived width of the corridor to assist with creating a self-explaining environment
- Mitigates headlight glare from vehicles in the opposite direction
- Reduces stress in drivers
Considerations
- Proximity to lanes may require barriers to be installed where speeds are higher
- Trees in medians on arterials would likely need to be removed during any widening

Further information
This solution can be combined with retention of existing trees, as can be seen at the Northern Road, Bringelly.
Example
Campbelltown Road at Edmondson Park provides tree planting in medians and verges, in what would otherwise appear a much wider corridor. The treatment assists indicate particularly to people driving a higher place value, with Edmondson Park centre and station nearby likely to attract people wishing to cross here. In this location wire rope barriers have been installed due to the lack of space between the trunks and the area where people will drive.
