Impact of the Charitas-Cafubá tunnel on vehicle travel time

One of the objectives of the Charitas-Cafubá Tunnel is to reduce travel time on the way to the city center of Niterói or the city of Rio de Janeiro. To measure the impact of the tunnel, a comparison of the travel time and vehicle flow of the current two existing routes after the construction of the tunnel with the single previous route was conducted. The results indicated that the travel time between the two alternatives after the construction of the tunnel approaches an equilibrium, both with a shorter travel time than the previous one. However, there was an increase in the total number of vehicles at the point of convergence between the routes. By analyzing the section after the convergence point, it is concluded that the reduction in the initial travel time provided by the Tunnel is counterbalanced by the increase in travel time in the segment after the convergence of the current routes.
