In transportation networks, traffic sensors are used to monitor the operation of transportation systems. A multi-objective detector location optimization is proposed. Four components are included in the objective function:(1) to cover more origin-demand pairs; (2) to obtain the maximum traffic data; (3) to maximize the gain of travel time error, and (4) to maximize the gain of travel time predication. This problem is solved by applying a distance-based, multi-objective, evolution algorithm. Numerical experiments are conducted on a small simulated network and Sioux-Falls network, respectively. An analysis about the obtained Pareto frontier is done. The results demonstrate the feasibility and effectiveness of the approach.
