Even though I generally don’t like slow traffic, today after work I managed to turn this to a kind of victory: most of what you see below was written on the bus trip. It was mere 50km but seems like the national day for beginning of the school year means a lot, traffic-wise. There were quite a lot of buzz.
What I understood on the way home was that in order to really gain insight to this project, where I’m talking about the mass transit systems, it would be really good to make some tabular examples.
I like to gather a simple model of traffic modes and then collect some rough data on properties for each of those modes. At first I came up with 9 modes and 2 properties. The first step would be to make a rough sketch of the model. It’s interesting how there are fundamental differences, like: a train can “skip” car traffic (railroads are unaffected by cars, at least directly). Airplanes don’t follow roads – but they follow certain other limitations. Train vs. flying? When should one pick a flight, when is train still more suitable perhaps due to economy, time, or the ability to either relax or do work during the trip?
The traffic is an interesting phenomena. It can be thought of as…
- being a mechanical system
- being a dynamic system (truly thinking of the traffic flows, queues and so on)
- having certain costs for the individual and for anyone who is responsible of setting up the “circuits” (roads, rails, waterways) and any infrastructure related to those
- traffic is ultimately there to enable people the movement and extend their capabilities, space-wise
There’s a lot at play when we’re thinking of mass transit systems. For example, one interesting property is that you can’t isolate the systems; you most likely could not “own entire circuits” (or eg. road systems) and then just plant precisely the required taxis or buses in there, and reap profits. Traffic doesn’t work that way. It’s an interplay between all the actors involved. Only railroads seem to be somewhat prone to be very controlled and even monopolistic.
Mass traffic (public transportation) is a kind of ever-hot potato, around the world. The level of its penetration (use) and sophistication varies probably quite a lot. The type of vehicles used also depends on geography; is the country mountainous or flat? Does the country stretch over a large area or is it small? Or something in-between?
More to come!
