DVDH is providing its expertise to the city council to study the extension of the Bordeaux tram to reach the town of Gradignan, south of Bordeaux. The services include presenting alternatives for achieving a low-carbon mobility system for the town. The study then focuses on the tram option: estimating potential demand, analyzing fares, estimating costs, benchmarking, and evaluating the benefits in terms of modal share and CO2 emissions.
