The future of public transportation

tokyo.jpegWe are urban animals. In other words, inhabitants of a concrete-and-steel jungle. The trees become scarce and their counterpart, the skyscrapers, literally touch the sky. Enough poetry, let’s go to the real world.

The average city has a continuously growing population. Millions. The big urban areas count their members by tens of billions. Every inhabitant has needs and the biggest of them is transportation, be it public or private (personal).tramway

Despite the numbers, most of the people still move inside the cities by foot, bike, bus or subway. The last two options are by far the most widely used. Paradoxically, there is a shortage of means of public transportation at peak hours. People have to wait for the next bus or train. This is perfectly normal and yet it doesn’t answer to the question, nor does it suggest how to improve the system.trains.jpeg

Add more buses or trains ? Big problem. Trains need a minimal time for decelerating, stopping, and accelerating for each station. Too many trains and new problems arise. Same for buses.  Too many buses clutter the  traffic. Too few and the passengers are dissatisfied. Rush hour adds more complexity to the system. How to solve all these issues ?Map_of_the_Salzburg_trolleybus.png

Some might say that there is no solution. Some cities have thought at reducing the number of cars in order to favor the buses. Yikes! This is not a solution. Cities will have more and more inhabitants.  The public transportation is the solution, but in order for it to be such a solution, it needs to be redesigned.
