First thing is the zoning, all residential and industrial zones are high density.
The demand for tech in this region is very high due to highly developed cities. Most commercial zones are high density, except those on the outer edges. I forced the high densities CO$$$ buildings to develop near residential area or monorail stations to shorten commute time.
I put a lot of efforts into the public transit system. Most residents can get to work using bus/subway/monorail. There is only one passenger train station for transporting residents in a neighboring city into Horwich to work, all other train stations are for freight.
Because there aren’t many people driving, road traffic is always low and most commercial buildings do not have high customers. To prevent buildings from becoming vacant, commercial zones are limited so the demand is kept high. As a result the advisor keeps telling me businesses are scouting for office advantages :) Also every residential building has jobs and there are no abandoned buildings.
The industries in the northeast supply jobs for a neighboring city. The monorail station shown below stops at the commercial center of the industrial park, it’s heavily congested due to the number of people coming in to work and also using this station to go to another neighboring industrial only city.
Overall congestion in the city.
Monorails actually generate a lot of air pollution.
A lot of subway stations and bus stops are over capacity because they transport so many people to work. On a side note, the average commute time is around 50 minutes, most residential buildings have medium commute.
There is a a bus stop in every block of residential areas. Subway stations are less common but are usually placed right next to high density residential lots. Because industrial parks are on the outer parts of the city, monorail and subway are used to shorten the commute. Usually people travel by subway/monorail then by bus to work.
