The roadway infrastructure of Brazil is the primary mode of transportation for its population. However, the condition of the Brazilian roadways has not improved correspondingly to the rising socio-economic development of the country. Furthermore, the growth in vehicle flows in large and medium-sized cities approaches saturation flow and roadway system capacity. Thus, the traveling from point A to point B in an efficient, safe, and desirable manner has not been achieved. Under current circumstances, this case study set out to analyze the performances of intersections located at AL-110 highway in Arapiraca - Alagoas by performing a traffic microsimulation in addition to proposed alternatives to improve traffic congestion and conflicts observed in the field. Thereby, the results of the simulation show the current configuration has not satisfactory handled the traffic volume. In addition, the proposed alternatives have resulted in considerable improvements in traffic capacity and fluidity, contributing to the reduction of travel time. These improvements consequently decreased consumption of fuel, emission of gaseous pollutants, the maintenance cost of the fleet’s vehicles, and the occurrence of accidents in the region.
