Nikolaos Geroliminis

Traffic congestion is increasing in major cities. The construction of new infrastructure is not a feasible solution to decrease congestion. My research to date has focused on developing more sustainable transportation systems by improving the use of existing facilities. Specific areas of research include modeling and estimation of travel times and other performance measures in arterials; location of emergency response vehicles in transportation networks; urban transportation and gridlock in cities.
