How can we bring these topics under one essay or an article?!

Spending too much time at your computer
Reducing traffic in large cities
Building more car parks in large cities
Using public transporter instead of cars
Speed limits

Perhaps the correlation is that people who work from home stay out of traffic and often spend more time working than if they went into the office.
