Description 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:
Wide range of services offered, tailored to heterogeneous categories of users, including both public administration and officers, and final users.
High system scalability. The system architecture is flexible enough to be applied to urban areas of different size. The area covered by the service can be seamlessly extended without a major upgrade of resources. Furthermore, it is possible to offer custom services, specifically designed for a given application scenario.
Low cost, with respect to traditional ITSs. The overall cost is kept relatively low by using innovative technologies on COTS devices, as well as open protocols and standards, without reducing the quality of service and system performance.
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:
Producing the system requirements, the system architecture and the test plan.
Designing and deploying the wireless backhaul.
Developing the data center of Ipermob.
Acting as the main system integrator, in order to produce a prototype implementation to be installed and operated in the area of the Pisa International Airport “G. Galilei”.
