A biochemical method of communication through the use of scents by creatures of the same species is being utilized in the Digital Pheromones project as a technical approach to optimizing vehicle routing in street traffic networks. This R&D project being conducted by Siemens Corporate Technology in cooperation with the Ars Electronica Futurelab and Johannes Kepler University Linz is based on the fundamental principle of bionics. It takes the idea of the collective intelligence of ant colonies as a model of natural self-organization in order to distribute traffic volume in a way that best utilizes the full capacity of a city’s network of streets and to optimally route individual motorists.
Ants leave behind scents called pheromones that show ants coming after them the path to a food source. The digital counterparts of these pheromones are flows of data based on the amount of time a motorist needs to cover a particular distance. Collecting all the digital pheromones of individual motorists on a virtual city map generates a continually updated picture of the traffic situation in the entire street network. Each vehicle selects its route on the basis of an assessment of the current pheromone landscape.
