Right from their first introduction the most advanced de-icing systems and techniques for preventing snow from settling on the roadway were used. The main problem of the Bologna- Florence motorway is the need for immediate intervention as heavy goods traffic makes up more than 50 per cent of all traffic with the result that if a single goods vehicle skids on snow and blocks the carriageway, all the traffic is immediately blocked, including the snow clearing vehicles. It is very important to know the location, in real time, of all the vehicles and what they are doing: i.e. the operations being carried out. As from 1 November 1999, this has been made possible through a new centralised control system (at varying levels of the sub-sections and section) to determine the location and operating mode of each vehicle engaged on ice removing and snow-clearing operations called S.I.S.M.A. Satellite localization of snow-ice removig vehicles. The vehicles are equipped with GPS, global positioning system, devices that allow them to determine the geographical co-ordinates of their position through the satellites within reach of their sensors. The system can also manage vehicle performance by varying its operations according to the stretch on which it is operating, and especially as regards the appropriate dosage of salt for the morphology of the road. This isobtained by a self-learning programme implemented over the route, ahead of full-scale winter operations, for each of vehicles in order to distribute the correct quantities on viaducts, fasticing shadowed areas, areas with drainage pavements and similar (dosages, type of salt (dray or humid) according to a predetermined programme. The system will naturally also store the intervention times and all the operations performed, along with the relative climatic conditions monitored by on-board sensors (at present, generally the temperatures of the road surfaces) and in so doing it provides a highly reliable management tool for verifying efficiency, providing data to the press, accountancy requirements and any legal controversies. A survey of the actual state of the road represents the next stage in the development of the system (which will also be carried out with vehicles in movement equipped with GPS/GSM devices) along with the development of additional sensors for road surface temperature and possibly also other parameters related to weather forecasts such as the temperature and the relative humidity of the air. he next step will be the use of the internet to host conversations with motorists equipped with the appropriate mobile telephones to whom information can be given in real time, while they are in transit, on the conditions of the pavements: temperature, or rather the possibility of icing, treatment with salt, its effectiveness, etc. The system, therefore, will not only provide information for management purposes but also real time information for users for the routes actually being negotiated and on all other points of interest. It must be clear that the SISMA methodology cannot by itself resolve all the problems, especially in the parts most congested by heavy traffic as the solution is the result of the interaction between a better monitoring of the actions in progress and the work of whoever operates the means controlled by the SISMA system.

Modern operations for winter operations were introduced onto the Bologna - Florence motorway in the 1960s. Right from their first introduction the most advanced de-icing systems and techniques for preventing snow from settling on the roadway were used. The main problem of the Bologna- Florence motorway is the need for immediate intervention as heavy goods traffic makes up more than 50 per cent of all traffic with the result that if a single goods vehicle skids on snow and blocks the carriageway, all the traffic is immediately blocked, including the snow clearing vehicles. It is very important to know the location, in real time, of all the vehicles and what they are doing: i.e. the operations being carried out. As from 1 November 1999, this has been made possible through a new centralised control system (at varying levels of the sub-sections and section) to determine the location and operating mode of each vehicle engaged on ice removing and snow-clearing operations called S.I.S.M.A. Satellite localization of snow-ice removig vehicles. The vehicles are equipped with GPS, global positioning system, devices that allow them to determine the geographical co-ordinates of their position through the satellites within reach of their sensors. The system can also manage vehicle performance by varying its operations according to the stretch on which it is operating, and especially as regards the appropriate dosage of salt for the morphology of the road.
