One of the consequences of higher mobility is the increase in air pollution. The increase in traffic volume at intersections impacts delays and congestion, thus producing higher air pollution concentrations. This research aimed to identify intersection performance and analyze air quality at existing conditions, then propose traffic management scenarios that increase intersection performance and reduce air pollution at a time. This study was taken on Soekarno-Hatta - M.T. Haryono - D.I. Panjaitan intersection, in Malang. The intersection performance was at the worst level of service (LOS F) for each approach from traffic analysis using the Indonesian Highway Capacity Manual. At this condition, the prediction of air pollutant parameters was out of standard level. The CO concentrate was lower than the standard level, while NO was higher than the standard level. Traffic management was proposed by controlling the movements at the intersection approaches and the number of phases at the intersection. The third alternative can improve intersection performance from F to C and decrease air pollution. The concentration reductions are about ±37.4% for NOx and ±61.3% for CO from the road median to the end of the road. © Published under licence by IOP Publishing Ltd.
