📋 Tender Overview
Rete Ferroviaria Italiana FS Italiane Group presented the study to the Lombardy Region and the local authorities involved to identify a plano-altimetric layout of the new road and rail crossing of the Adda river.The objective of the study was to evaluate the performance of the individual intersections on which the vehicular flows resulting from the redistribution of the traffic that will gravitate on the new bridge between the Municipalities of Paderno and Calusco dAdda converge.For the San Michele bridge RFI confirms that it is essential to maintain the current operating conditions and the monitoring of the work which will allow it to function for about ten years. Beyond this period no rail or vehicle transit is envisaged.Therefore the time horizon of the study was defined as 2030.Traffic analyzes were performed by building a regional-scale model for a total of 65000 km of network identifying all the insistent routes on the new bridge in three different future scenarios and quantifying the related traffic flows. The most critical road intersections were then identified and their performance assessed.In the scenarios examined various infrastructures for future construction were taken into consideration such as the variant of Cisano Bergamasco the variant of Brivio to the SP342 the variant of Calusco.In summary it is assumed that the new road bridge will attract a total of 550600 vehicles per hour in both directions during the morning rush hour with an estimated increase of approximately 50 compared to the current configuration.The study also defined possible interventions for the renewal and optimization of traffic light systems which will make it possible to improve the quality of service Service Level in some road intersections despite the increase in traffic assumed in the project scenario 2030. For the other at-grade crossings the non-variance of the service level between the state of affairs and the project scenario by 2030 is confirmed.On the positioning of the road bridge RFI hopes for the widest consultation between all the Bodies and believes that even if the sharing process takes time it will have undoubted benefits on the duration of future planning processes. In this regard the comparison between the technicians of RFI and the Lombardy Region continues for the in-depth analysis of the proposed study the results of which will be analyzed in September.
