# A Choreography-Based and Collaborative Road Mobility System for L'Aquila City
## 4 Case Study  
At the moment of writing, ten years after the earthquake, L'Aquila represents a challenging context. It was 3:32 a.m. on 6 April 2009 when an earthquake struck the city of L'Aquila, causing death and destruction [49]. After this devastating event, L'Aquila has started a long but inexorable process of social, physical and economic reconstruction that has allowed it to receive the SMAU (Smart Communities Milano 2015) award for the project \"L'Aquila Smart City: Rete Elettrica Intelligence e Mobilita Verde\" (Smart Electric Grid and Green Mobility) [50]. The operations in progress will make the new electricity grid more secure and efficient and allow for connect to the network the private ecological equipment for the production of energy, allowing for redistributing this energy in case of blackouts. Taking advantage of the broadband designed for the electricity network and the reconstruction work already in place, the project aims to diffuse the optical fiber extensively, touching all buildings, and hence increasing the speed of information exchange via the Internet. Finally, the installation of charging stations for electric vehicles and awareness-raising activities aimed at citizens, car manufacturers and local administrations wants to facilitate the diffusion of sustainable mobility in the city to allow citizens to move over the wide area without weighing on the environment, reducing emissions of harmful gases and using fossil fuels. With the opportunity to interpret reconstruction in an innovative way and the absence of conditions hindering the widespread deployment of technological solutions at the base of a Smart City [51], the INCIPICT project, coordinated by the University of L'Aquila and launched in late 2014 [52], supports the economic development of the city and improves the quality of life of citizens through a widespread use of Information and Communication Technologies (ICTs). The project aims to create a Living Laboratory model, leveraging on the reconstruction of buildings and the radical re-organization of the city's sub-services network (water supply, electricity supply, telecommunications networks), to create essential and enabling components for innovative urban development and support for research activities. These innovative services will be supported concretely through a project of experimentation of the 5G technology [9]. The project is promoted by the Ministry of Economic Development (MISE) [53], which will be carried out in partnership with Open Fiber ([[https://openfiber.it/en](https://openfiber.it/en)]([https://openfiber.it/en](https://openfiber.it/en))), a joint venture of Enel ([[https://www.enel.com](https://www.enel.com)]([https://www.enel.com](https://www.enel.com))) and Cassa Depositi e Prestiti ([[https://en.cdp.it](https://en.cdp.it)]([https://en.cdp.it](https://en.cdp.it))), Wind Tre [54] and ZTE ([[http://www.zteitalia.it](http://www.zteitalia.it)]([http://www.zteitalia.it](http://www.zteitalia.it))). Our use case belongs to this highly challenging context. In particular, it realizes a Collaborative Road Mobility System (CRMS) for L'Aquila city. The aim is to realize a system that allows vehicles and transport infrastructure to interconnect, share information and use it to coordinate their actions. The CRMS provides traffic coordination services exploited through a mobile app for assisting drivers in the most eco-friendly and comfortable driving experience [9]. Referring to the Smart Mobility indicator defined in [55], related system key objectives, and foundational mobility model concepts in [56], our CRMS represents a mobility system in its \"intermediate phase\" of implementation. In fact, it is a pilot project collocated within the context of the ongoing INCIPICT project leveraging a work-in-progress optical network infrastructure. Its key objectives are the reduction of air pollution and traffic congestion. In the future, with the adoption of 5G technology in the city of L'Aquila, CRMS will move to a mature phase.
