Original sentence: Auckland is highly dependent on private vehicles as the main form of transportation, with only around 5% of all journeys in the Auckland region being undertaken by bus.Bus services in Auckland are mostly radial rather than ring-routes, due to Auckland being on an isthmus.This results in substantial traffic congestion during peak times.With public transport use declining heavily in usage and provision during the second half of the 20th century (a trend mirrored in most Western countries such as the US), and increased spending on roads and cars, New Zealand (and specifically Auckland) now has the second-highest vehicle ownership rate in the world, with around 578 vehicles per 1000 people
Edited sentence: Auckland is highly dependent on private vehicles as the main form of transportation.Cox further stated that no other centre in New Zealand achieved as high a market share than Auckland city centre.Declining public transport use is a trend overseas, as evidenced over the past 100 years in the USA.Despite the negative perception of public transport, Wendell Cox, public policy consultant said in 2001 that Auckland's "public transport's downtown work trip market share is 31%" compared to Wellington's 26%.The bus and train networks have seen enjoyed increased patronage and service, but service is still limited in comparison to other cities of the same size (and higher density).The bus services are mostly radial rather than ring-routes, due to Auckland being on an isthmus.This focus has been partly due to the low population density of the Auckland region (compared to most cities in Europe and Asia), and is further accentuated by the comparatively long travel distances on the isthmus.This results in substantial traffic congestion during peak times, especially for New Zealand levels, though comparable to many other cities worldwide.With public transport usage declining heavily during the second half of the 20th century, and increased spending on roads and motorways, New Zealand (and specifically Auckland) now has the second-highest vehicle ownership rate in the world, with around 578 vehicles per 1000 people
