The goal of Cagliari 2020 is to optimize urban transport, reducing journey times and, above all, improving air quality. In this aspects Cagliari is an ideal case study because it can count on a state-of-the-art infomobility infrastructure in Europe. First of all, a metropolitan network that interconnects all bus stops, with an operating center monitored 24 hours a day. This allows for real-time info on bus frequency and timing at each stop. To which is added an architecture of gates, connected to the accesses in the city, which register the vehicles that flow and leave again. Moreover, all buses are geo-referenced: they have a GPS system that acquires their position and communicates it to the operation centers.
The information on flows, delays and advances make it possible to regulate the speed of movement of the vehicles and the activation of the traffic light systems on the roads crossed.
Cagliari 2020 acquires the information in real time through the netcentric paradigm: a dynamic and pervasive network (urban information grid) whose nodes can be both fixed and mobile.
Tracing the habits of users moving through their mobile devices (like smartphones). Anonymously and in compliance with privacy regulations. The number of moving vehicles is captured with extreme precision, capturing the radio signals of the devices along the main road axes. The collection of the info allows to have a precise mapping on the flows in the area of interest.
The objective is to adopt actions, in real time, according to extraordinary events that may occur in cities (accidents, demonstrations) and provide alternative routes. Other useful data are those on parking areas or the development of solutions for shuttle services on demand. On the basis of the information collected, a shuttle booking system can be created, in real time, from one point of the city to another, within pre-established routes.
Another interesting aspect is the acquisition of data on the energy and environmental impact of traffic in the city. The buses are exploited as probes with sensors that record the polluting emissions of the ether. The control unit will be installed on the vehicle, collect the data and send it to the plant. From the punctual photo of the air quality we will find out how much energy is consumed to cover a certain stretch, and how the mobility system impacts on the population also from the health point of view.
The optimization of energy consumption, on a national scale, is not trivial: it allows an estimated saving of several billion euros. As well as the costs of road accidents that can be reduced: costs that affect, at European level, about 2 percent of GDP. Without considering the calculation of health costs on the inhabitants. Savings that can be reinvested in the services themselves.
Logic is the long term, where the project is a propeller of other business, and new platforms fed over time. There is already an agreement with Cagliari 2.0, the future network of entrepreneur Mario Mariani, father of the incubator The Net Value.
But the future is also beyond national borders: helping start-ups produce services that create economic results and in return, part of the profits invoiced will fund new projects for the survival of the ecosystem. Chicago, which has 3 million inhabitants, would like to experience the platform that will be ready soon.
