The problem of the traveling salesman is a useful approach to determine the most efficient [shortest length] routes to take within a given transportation network.  In this exploration, I used the streets of downtown Rochester as the network and all the intersections as start and end points of a desired route.

Giulio Piacentino with McNeel Europe created a Grasshopper component that attempts to solve this problem.  Here is the aerial image of downtown Rochester:

Below are all the intersections:

…and from the intersections is the network of street.  This network includes all the possible routes one could take  from any intersection to another.

The simple grasshopper definition below allows testing of almost an endless number of paths.

This animation demonstrates a selection of random start and end points [connected by a yellow line], and draws the shortest route from one to the next by following the streets [red lines].

While Curitiba‘s rapid bus transit system is more familiar to the world, Bogotá also has an exciting and successful one of its own [TransMilenio] where the city’s original plans to build elevated highways were eliminated in lieu of a more robust bus system.  Their buses are somewhat like subways in that they have their own lanes and passengers pay at stations [instead at the entry of each bus].  There are also free feeder buses that transport people in the outer areas to the stations as well as free bicycle parking at the stations to encourage people to bike to and from the stations.  Take a look at the video below to learn more about the system.
