Scuola Superiore Sant’Anna lead a research project in Intelligent Transportation Systems funded by the Tuscan Regional Board through the European Regional Development Fund: IPERMOB, a multi-tier Information System for urban mobility, recently ended in June 2011.

IPERMOB testbed chosen for the proximity of the residential  buildings and the resource criticity (roads and parkings).


IPERMOB proposes a new generation of integrated systems based on the optimization and inter-operability of the chain formed by data collection systems (road-side and vehicular based); aggregation, management, and on-line control systems; off-line systems aiming at infrastructure planning; information systems targeted to citizens and municipality to handle and rule the vehicle mobility. As testbed, whose functionality has been publicly demonstrated in May 2011, IPERMOB provided real-time information about parking availability and vehicle flows and quasi-online traffic modeling for the landside of the International Airport of Tuscany, Pisa, Italy

The IPERMOB testbed architecture

The IPERMOB testbed architecture consists of a three-tiered infrastructure:

  • data collection,
  • data transport, and 
  • final user application  

The data collection tier adopts low-cost WSN (running computer vision distributed processes) and Vehicular Ad-hoc Networks (VANETs) technologies to estimate traffic-related information. The goal of such visual WSN is to collect information about parking lot occupancy and traffic flow.

The WSNs are in turn connected to the rest of the system by IEEE802.11h point-to-point bridges. A special node in the WSN, the coordinator, acts as a gateway between the WSN and the upper layers.
The data transport tier provides, to the upper layer, a standard interface for accessing the data produced by the lower layer and stores them for future use.
Applications can be on-line control systems providing real-time information to the users (drivers, police, etc.), or off-line systems aiming at infrastructure planning. The implemented prototype provides example applications of both types.

In May 2011 the Pisa airport landside has been equipped by visual Wireless Sensor Networks (WSNs), i.e., networks of tiny smart cameras, aimed at gathering information about parking occupancy and instantaneous vehicle flows through the main road segments.
