ISORT: Intelligent Self-Organizing Transport

Project brief ARC Discovery Project DP0878119
2008-10
   
Project summary

Intelligent Transportation Systems (ITS) are focusing on sensor observations and information for local actions, such as driving assistance or congestion avoidance, subsumed in the autonomous vehicle and telematics. Global actions, e.g., wayfinding and trip planning, are frequently ignored. This is where the current project begins. We are studying self-organizing transport for managing global decisions. Self-organizing transport is realized by a mobile sensor network composed of intentional and social agents. We develop computational models of the ontologies of various agents in urban ITS with the aim to let them communicate locally and act globally. This paradigm shift enables an ad-hoc transport management design that is inherently ubiquitous, real-time, and independent from any external infrastructure. The design is tested in simulations, and demonstrated in a mobile sensor network.

From previous research (Winter and Nittel 2006; Raubal et al. 2007), an intelligent self-organizing transport network is characterized by a cycle of two processes: a synchronized negotiation process and a travelling process. In the negotiation process, different ontologies of the agents have to be overcome in an ad-hoc manner. In the travelling process, agents cross over multiple modes of transportation with different degrees of freedom and autonomous, flexible behaviour in response to local transport demand or supply. Current work considers the fundamental ontology model of communication between ITS and wayfinders, and collaboration between multiple modes of transportation (Winter and Wu 2008).

Project participants, cooperations and links The project follows up an international collaboration with Silvia Nittel (USA) and Martin Raubal (USA). The original idea came out of a discussion with Monika Sester (Germany).

The project collaborates with the ARC Network for Intelligent Sensors, Sensor Networks and Information Processing (ISSNIP), and participates in the Rowden White Sensor Network Lab.
