My trip to work yesterday took 1 hour and 20 minutes. An accident caused a traffic chaos. Irritated, I looked at the bus that tried to squeeze its way in to my lane.
Buses should have their own lanes, for many reasons.
I did some back of an envelope calculation for my cost for travelling to work (40 km one direction) and I did some rough estimates of the resulting CO2 emission.
It is most expensive to go by car and it also gives the highest CO2 emissions. The bus costs, as calculated as cost without taxes and subsidiaries, less than 20 kr.
Now, a lot of political attention is bought to the use of alternative fuels from agriculture, such as ethanol and biodiesel (biogas should not be categorised here, being a combination of waste management and fuel source). The alternative fuels are subsidised and does not bring taxes to the society. The cost is therefore somewhat higher, and the CO2 advantage is modest.
While the infrastructure investments for modern bus systems, Bus Rapid Transit (BRT) are modest, the operational cost decrease a lot.
For trains and metro almost no one is questioning the need for specific infrastructure.
If buses were given the same treat as other means of public transports it would give a major improvement of both the cost and the environment.
