Assessing the environmental impact of TSM: a case study of the city of Tampere

Urban transportation systems face increasing challenges from rising traffic volumes and their associated environmental impacts, necessitating innovative traffic management strategies. This study explores the environmental effects of traffic signal management (TSM) solutions, focusing on the transition from fixed-time control to advanced actuated and adaptive systems. A case study was conducted along a six-intersection urban corridor in Tampere, Finland, using microsimulation modeling integrated with emission evaluation tools. The methodology evaluates key performance indicators, including travel delays, stops, fuel consumption, and pollutant emissions, under varying traffic conditions. Aggregated analysis provides insights into corridor-wide impacts, while intersection-specific evaluations highlight localized variations shaped by traffic flow and geometric configurations. The study also underscores the importance of precise scenario characterization to enable robust comparative analyses and presents a replicable framework for assessing the environmental and operational benefits of TSM solutions.
