The IPERMOB project has the goal of designing and implementing a urban-scale Intelligent Transportation System (ITS), using low-cost innovative technologies. The architecture of the ITS consists of three tiers to keep the following issues well separated: data collection and aggregation; data publication; services.
The key features of IPERMOB follow:
Wireless sensor networks placed all over the coverage area collect real-time data, e.g., vehicular traffic flows, status of parking lots.
The collected data are conveyed via broadband wireless links towards a collection center, which also provides indexing and archiving functions. During transport, data are aggregated into priority classes depending on the urgency of the data: higher priority traffic is provided with a better level of quality of service than lower priority traffic, in terms of reserved bandwidth and latency.
The data stored are processed in real-time and fed to decision-making processes being carried out by the system users and vehicles in the covered area.
Examples of real-time high-level data: available parking lots, both for public use and reserved to the system users only; text messages directed to the system users; traffic congestion areas; best-path search hints; average travel time; warning messages.
In addition to this real-time use of IPERMOB, another goal of the project is to derive new traffic model algorithms at both macro- and micro-level. This will eventually support the refinement of the existing modeling tools, in terms of both accuracy and resiliency.
INTECS has a key role in IPERMOB, being involved in several issues, including:
