Invest in new rail links and reduce pass through due entire countries.
Why is this important?
A huge amount of in- and exports across the countries are done by trucks. These trucks cause air pollution, noise and worsen street conditions.
Nowadays everyday products are ordered on the internet from all over the world and far distances of transportation is not a big deal anymore .
An investment in better infrastructure can ensure cleaner air, and renew and expend the rail links. When more people will go by train rail ticket are easier to afford and it will decrease the need of a car. Unfortunately the costly car is still a must for more rural areas.
I am a passionate biker and hate to suffocate on the exhaust fumes of vast trucks.
