Expansion of major cities in India, with its fast-growing economy, has led to a drastic increase in the requirement for basic utility amenities viz. electricity, communication, water etc. There has been a substantial emphasis on developing an underground utility network for providing the essential utilities to people. This leads to excessive construction works both for the installation of new underground tubes as well as for the repair and restoration of the existing ones. Since most of these facilities are placed beneath the roadway surface, the excavation and construction at these sites lead to a reduction in the roadway width, causing congestion. This study analyses the impact of carrying out the underground utility works on road traffic and users at four urban locations in the city of Bengaluru, India. For each site, PTV VISSIM software is used to simulate vehicle trajectories for alternative scenarios with varying obstruction widths using the actual observed traffic volumes and compositions. Vehicle trajectories are fed as inputs to the international vehicle emissions (IVE) model to analyze the impact on transportation systems. The effect is studied in terms of average speed, exhaust emissions and fuel consumption for different classes of vehicles. There is a consistent drop in vehicular speeds for all classes of vehicles with increased obstruction width at all the locations, although the amount of change depends on the characteristics of traffic at that site. While the changes in the vehicle emissions and fuel consumptions are not as consistent in their direction as the vehicle speeds, it is not surprising given the complexity of the vehicle interaction dynamics on Indian roads and the current vehicle technologies. In general, there seems to be an increase in the emissions and fuel consumptions with an increased obstruction width. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
