Answer: To be honest, most groundcovers will not withstand lots of foot traffic, so an alternative suggestion might be to blanket the area with bark chips or install a path or stepping stones with groundcover on both sides. If that doesn't appeal, you can plant Dichondra or Lippia repens(Phyla). Some other traffic-tolerant plants include those that offer more color and texture than the above, such as Erysimum 'Orange Flame' or Leptinella gruveri. Caring for these plants is quite similar to caring for a lawn. They need good light, good drainage and good soil. Gruveri can tolerate the heaviest foot traffic of all.
Hope these suggestions are helpful!
