This chapter will focus on how new transit technology and corridor-regeneration policies can help transition greyfields. It builds on Chap. 3, which outlined the new distributed green technologies and their potential to help with urban regeneration in the greyfields at precinct scale. Transport systems are the sole focus of this chapter, as they have a very specific ability to help with urban regeneration via transit-activated GPR, given that accessibility is probably the largest city-shaping mechanism.
