New Book Chapter draft: Self-organizing urban transportation systems

Self-organizing urban transportation systems

Carlos Gershenson. To be published in "Complexity theories of cities have come of age", edited by Juval Portugali and Han Meyer (Springer, 2010).

Abstract: Urban transportation is a complex phenomenon. Since many agents are constantly interacting in parallel, it is difficult to predict the future state of a transportation system. Because of this, optimization techniques tend to give obsolete solutions, as the problem changes before it can be optimized. An alternative lies in seeking adaptive solutions. This adaptation can be achieved with self-organization. In a self-organizing transportation system, the elements of the system follow local rules to achieve a global solution. Like this, when the problem changes the system can adapt by itself to the new configuration.
In this chapter, I will review recent, current, and future work on self-organizing transportation systems. Self-organizing traffic lights have proven to improve traffic flow considerably over traditional methods. In public transportation systems, simple rules are being explored to prevent the "equal headway instability" phenomenon. The methods we have used can be also applied to other urban transportation systems and their generality is discussed.

Mi nombre es Emmanuel y soy el director de un cortometraje universitario titulado El barrio perfecto. Encontré unas fotos tuyas en internet y me gustaría usarlas bajo tu permiso en una escena. Las fotos son las siguientes: y

El corto está en proceso de terminar pero puedes ver el primer corte aquí:

Hola Emmanuel,

Sí, con mucho gusto.

Me gustó el corto. Una pregunta: ¿la protagonista el búlgara?
